Luck presents Hollywood. The Luck's Radio Theater brings you Merle Oberon and Jean Autry in The Cowboy and the Lady. Ladies and gentlemen, your producer, Mr. Cecil V. DeMille. Greetings from Hollywood, ladies and gentlemen. Among all the modern improvements of this changing world, there's one old time invention that we still can't do without. The American Cowboy. Science has failed to unhorsen because it never devised a machine that can rope a steer or draw a lot of people into a motion picture theater. Hollywood owes more to the cowboy than Detroit does to the houseless carriage. And if you're anything like me, thrills of memory run up and down your spine at the very mention of William S. Hart or Tom Mix. Today, the king of the cowboys is Jean Autry. He's the hard-riding hero of boys and girls both young and old from Butte Montana to the Bronx. And tonight we rope Jean Autry and put him in the Luck's Radio Theater corral. Of course, every story about a cowboy must have a lady to give it the romantic touch. So we threw our lariat in the direction of Warner Brothers where Merle Oberon is making a picture called affectionately yours. Tonight you'll hear this charming lady playing the same role in the cowboy and the lady that she did in the Samuel Golden picture. Before this play is over, we're going to cover a pretty wide stretch of territory from as far east as Palm Beach to the somewhat more rugged neighborhood of a Rocky Mountain Ranch. And in either of those localities, or just about any place in between, you will find that our product is far from a stranger. It's a very good reason for that, too, because Luck's Flakes is just as welcome to the lady whose front yard is a mountain slope as it is to her sister under the skin who hasn't any front yard but lives in the city apartment. It's obvious, even to a mere man, that they both want their hands to stay lovely, but you can't run a house without washing dishes in either place. And some really chivalrous help with that work has made Luck's Flakes a hero with the ladies from coast to coast. Now we have a big package of romance and adventure for you. So let's unwrap it right away by raising the curtain on the first act of the cowboy and the lady, starring Jean Autry as Stretch Willoughby and Merle Oberon as Mary Smith. The Silver Bowl Club is running full blast. The diners crowd the table, dancers crowd the floor. And in the back room, which is the real reason for the club's existence, the roulette wheel is humming merrily. It's in the gaming room that we meet the lady of our story, young and lovely Mary Smith. This is her very first visit to a club of this type, and her eyes sparkle with excitement. With her, and also a first visitor, is her Uncle Hannibal. Well, Mary, how do you like it? Oh, Uncle Hannibal, it's thrilling, but I'd hate to think of what fathers say if we knew we were here. I'll stop worrying about your father. We're here to have a good time. See, would you like to risk a few dollars, huh? You mean gambling? Sure. But I've never gambled Uncle Hannibal. Neither have I. What do you say? Well, I... Okay, everybody, line up against that wall. Hannibal, what is this? I don't know. Come to that door, Pete. Nobody gets out of this room. He don't grab that wheel. That's exhibit number one. It's a raid. That police. Oh, Uncle Hannibal. No, no, no, it's all right. I can handle this. I'll take care of everything. All right, come on, folks, up against the wall, everybody. Just a moment, please. You two, Bob, get moving. Wait. My name is Hannibal Smith. Well, you don't say. Yes, I do. And this is my niece, Mary Smith. Now, listen, Bob, I'm an old hand at this game scene. There's 200 people in this joint, Bob, and 185 of them are named Smith. Now, line up against that wall. It's a raid.   That's exactly what I told the newspaper, sir. But they have a list of the guests, and one of them is named Mary Smith. I told them... They print her name out soon. Must be some other Mary Smith. I'm sure it was, sir. Send for my daughter. I'll ask her myself. Just a moment, Horace. You needn't bother sending for her. What's that, Hannibal? I said you needn't bother. I'm afraid it was our little Mary, all right? Oh, of course. You saw her, I suppose. No, I took her. Oh, you took her? Uh-huh. Will you please explain that? Sure. You see, I felt sorry for her. I'll bet she hasn't talked to a man in the sixties since she left school. I thought it was time she should see how the younger half lives. Oh, I've asked you many times, Hannibal, to please stay out of my affairs. Well, this is an unnatural existence for a girl, Horace. Mary is perfectly happy.  She's just trying to be loyal to your bigoted notion. It's faithful. Now listen, you wouldn't... Chester, you may go. Yes, sir. Hannibal, do you realize what you've done? Don't you realize that my name is being mentioned as a possible candidate for president? Horace, you haven't got a chance. Never mind that. A scandal like this may cost me the nomination. Mary and a gambling rate. We didn't gamble. We just danced and had a good time. Say they had a jam session last night with a done-your-heart-good. Hannibal, sometimes I think you're in your second childhood. Well, come on in. The water's fine. We've got to do something about this. We've... I've got it. Yes, sir. Yes, sir. Tell my daughter to pack her grips. She's leaving for Palm Beach on the next plane. Now listen, Horace, you can't do that. Keep quiet. I know what I'm doing. You've interfered enough around here. You're sitting out. Oh, sorry. Can I help you, Pat? No, thanks.  Letting yourself be bustled out of town this way. What am I to do? Break his heart? If the newspapers get too inquisitive, he's going to tell them I've been in Palm Beach for weeks. I'm afraid your poor father's in over his head. Why don't you stop him before it's too late? I can't. He wants that nomination so desperately. Sometimes it frightens me. Me too. You had a good time last night, didn't you? Oh, marvelous. The raid was thrilling. Yes. Palm Beach out of season is going to be pretty dull. That's right. Rub it in. Well, if you can find a young plumber, somebody lying around loose down there, you take my advice and grab him. You think you'd know how to talk to a young plumber?  Uh-oh, here's a gloomy gut. Yes, horse? You mind if I speak to my daughter for a moment? Okay, I'll have the car brought around. I've arranged everything, Mary. There are two maids in Palm Beach opening the house. They'll take care of him. Thanks. They'll be nice company, too. Mary, I can't understand what's gotten into you. You're good heavens, Father. What did I do that was so dreadful? I've tried to make it clear that without Henderson's support, my nomination is impossible. And you know how he'd react to a scandal of any kind. And what am I supposed to do? Live like a prisoner because Henderson's a narrow-minded fool? Mary. I'm sorry, Father, but it isn't fair to me. I don't see anyone, and I don't go anywhere. This is the first time in two years that I've been out, and I had to go with Uncle Hannibal. I can't allow you to destroy something I've worked on for years. Oh, perhaps you'd rather I give up the whole idea. Sometimes I wish you would. Mary. But maybe we could go back to living like normal human beings again, where we don't have to be under a microscope all the time. Oh, Father, we've to have such fun before you went into politics. Remember those wonderful summers on farm? Oh, don't be absurd, Mary. This is a great tribute. There'd be nothing left for me if this fell through. I see. All right, Father. Boris. The reporters are downstairs. Report us. Grab those bags quick. But I've not finished packing. Go on. Go on. I'll send you the rest. Cars at the back door. Hurry, Mary, hurry. Goodbye, Father. Goodbye, dear. Goodbye, Uncle Hannibal, and thanks for a wonderful time. Goodbye. Don't forget about that plumber. On the bed here. Yes, Miss. Ellie, did you find out if the reeds have opened their house yet? Oh, they haven't, Miss. There isn't a house in Palm Beach open at this time of the year. Except ours. Oh, Ellie. I'm bored. Yes, Miss. I've noticed this. Do you play any card games, Ellie? Let's see. Casino, Miss. Casino. I'd love to play Casino.  Well, I'd like to, but... Oh, you have a date. Oh, it's nothing, Miss. I can break it. It's only with one of the fellows at the rodeo. A cowboy? Yes, Miss. Oh, I wouldn't think of letting you break it. Have a good time. Oh, thank you, Miss. Ellie. Ellie, wait. Yes, Miss. Has, um... Has your cowboy got a friend? A friend? Uh, why, yes, Miss. But he's for Katie. Oh. I mean, I promise, Katie. Well, you see, it's a blind date, Miss. Blind date? Oh, that sounds marvelous. Will you be having your dinner off here, Miss Mary? Hello, Katie. I was just trying to induce Ellie to take me on your blind date. You missed? Oh, I don't think you want to do that, Miss Mary. Why not? He's a cowboy. Yeah, and they're awful particular... Oh, no, Miss. Oh, no, no, that ain't it.  Scared? Why should they be scared?  Cooperation once in a while.  Oh, I'm sorry, Miss. That's all right, Katie. Perhaps they'd be right. But what do you think? Huh? Do you think I'm a cold fish? Well, I... Go on, Katie, I don't mind. Well, you don't exactly siffle, Miss. What do you think I better do about it? Crash, I don't know, Miss Mary, but it's not your fault. You got it in you all right, but you've been held down so much, that's all. Yeah. Me and Katie talk about it a lot. Do you really? Sure. We always felt kind of sorry for you, Miss Mary. Thank you. Well, have a good time. Both of you. Uh, Miss Mary, if you really want to go, I think we can fix it up for you. A blind date? Sure. We'll give you a couple of pointers, and you might get five. Yeah, we'll show you our system. Oh, you've got a system. Sure. Well, it's sort of a system. Depends on what you run up against. For instance, he's a cold type and keeps giving you the icy stare. Well, if you made up your mind, you're going to get him to kiss you or bite right out by flaring him. That's maneuver number one. I see. Maneuver number one, factory. I'll remember that. That's it. Now, if that don't work, make him talk about himself. That's number two. But a man can't talk about himself and kiss you at the same time. No, but sooner or later, he's going to talk himself out, ain't he? I suppose so. Tell her about number three, Katie. Oh, number three, sure. Firemix. Of course, you can only use that in case of emergency. Tell him a hard luck story. I see. We're going to simply ask. Mm-hmm. That's it. Mm-hmm. That's like money in the bank. Just tell him what a hard time you've had of it and how you had to suffer. Then if you throw in a tear or two, he's yours. Uh, you think you can do it, Miss Mary? Well, I'd certainly like to try. Well, let's go. The rodeo's over in West Palm Beach. I'm ready. Now, let's see. Maneuver number one, factory. Maneuver number two, make him talk about himself. Maneuver number three, tell him a hard luck story. Is that all? That's all. Come on, then. Let's go and meet the cowboys. I wish they'd hurry. No need for suspense, Nick. One cowhand is just like another. Here they come. I was getting prettier every day. Ah, now you go. Hey, I want you to meet my friends, Stretch and Sugar. Oh, yeah. Hey, how are you, man? How do you do? I want you to meet Katie and Mary. How are you, fellas? How are you? Hi, Mary. Hi, Mary. And Mary, I want you on a pal stretch here to be good friends. Mary, this is Stretch. Oh, well. Hello. Hello. Oh.  Come on, girl. Yeah, come on. Well, I guess we ought to go, too, then. I guess so. Look, you don't seem very enthusiastic. Oh, sure I am, miss. Matter of fact, I'm hungry as a stare.  Yeah? I've seen lots of good riding, steeper chasing and high jumping, but you're about the best I've ever seen. Yeah? I got awfully excited when you threw that stare. Yeah? I was scared. I screamed. Didn't you hear me? Nope. Oh, well. Anyway, I thought you were just wonderful. I said I thought you were just wonderful. Oh, it's all in a day's work. Well, that finishes number one, doesn't it? Pardon? Oh, nothing, nothing.  Mary, isn't it? That's right. Mary Smith. Nice name. Mary Smith. Do you really like it? Sure. I like it fine. I'm so glad you like it. Look, why don't you say something for a change? Oh, I will. If I can think of anything important. Oh, I suppose being around with cows all the time, you don't have a chance to converse much. Cows ain't much on the small talk. I see. Let's go, folks. Come on, Mary. We're all going up to the house. The house?   Guitar? Oh, stretch, do you play it? Yeah. The guitar. Stretch. That was lovely. It'll do. Where's the others? I don't know. Out for a walk on the beach, I guess. It's such a beautiful night, isn't it? Oh, it's all right. Nice place here. Yes, isn't it? You work here, huh? Yes. What do you do? Oh, I'm a... I'm a lady's maid. Mm-hmm. Oh, but that's... I'll talk about me. Let's talk about you. Why? Well, that's maneuver number... I mean, I don't know.  Nope. Where's your home? Is it far away? Montana. Really? Montana? Yeah. I just told you. What's it like? Tell me about it. Hear that? What? A new chord. Listen. It's lovely. A little flat, I think. Say, what do you do for this lady you work for? Oh, I help her dress. No. How old is she? Oh, uh, about my age. Married? No. Well, what's she waiting around for? She hasn't found the right man yet. Mm-hmm. But look, you were going to tell me all about yourself. Oh, was I?  Me? I'm just a working girl.  I guess you've been around rich people too much. I haven't got you mixed up. Don't you ever get mixed up, Stretch? Not about things that matter. Do you always know what you want? I sure do. What? Well, I want a spread of my own. A ranch that'll run about a thousand head of cattle in a pretty valley with a crowd stream running right through the middle. And a nice house. And nobody else? Well, sometime maybe. A wife. And children? You bet. That's nice. Go on, Stretch. Well, that's all. Oh, Mary! Just a minute. Excuse me, Stretch. I'll be right back. Take your time. Yeah, Miss Mary. How you doing? Okay. Very badly. Your system's no good. It ain't ever failed me. Is that him singing? That's a good song. It doesn't mean a thing. I've tried maneuver number one and maneuver number two, and I'm nowhere at all. What about number three? What is it? I've forgotten it. Hard luck story. That's only for emergencies. Well, what do you think this is? That's right. Well, I'll give it a whirl. Mary! I'll tell you that you have a voice. Nope. Well, you have a marvelous voice. Not much chance to use it in Montana. Cow's ain't got no air for music. Stretch, I envy you. Nothing on your mind but your job. No trouble, no responsibilities. I wish my life were as simple as all that. Isn't it? You don't look to me like a girl that's had a tough time of it. You don't think so, huh? That's funny. That's really very funny. Oh, I'm sorry. I meant it. That's all right, Stretch. Say, maybe if you tell me something about yourself, I... Oh, no, no. I wouldn't want to burden you with my trouble. You might be good to get it off your chest. Maybe I can help. You're very kind. Is it your family? Mm-hmm. Father mostly. Your father? His. His drinking. Oh. He's drinking. Night after night. Sometimes for weeks without stopping. Well, can something be done about him? No use. We've tried. No ambition. No willpower. He hasn't worked for 12 years. 12 years? Well, who supports him? I do. What do you know? Anymore in the family? Anymore. Anymore children? Oh, yes. Yes. Five. Five? Well, that is five, including me. Don't any of them work? No. Why not? All girls. And you're the oldest. Gosh. Poor kid's sisters, and you support them all. Oh, not that I mind. They're such darlings, all of them. But sometimes it's a bit hard. Yeah. I can imagine. Last year, for instance, when both Dottie and Henrietta were down with the measles. At the same time? It wouldn't have been so bad if I hadn't been out of work. And what were the doctor bills piling up and... Sometimes I just don't know how I go on. Oh, gee. You poor kid. Oh, stretch.  No, no, no, no. Don't cry. Just here. Just put your head down here on my shoulder.  Stretch. You kissed me. Huh? Oh, I'm sorry, miss. I didn't mean it. Oh, no, no. Please don't be sorry. Please. Be stretch. Let's go. Your friends are leaving, stretch. Well, that means me too. Bye, Miss Mary. Goodbye, stretch. Bye, Miss Mary. Bye, Miss Mary. Goodbye. Goodbye. Bye, Miss Mary. Get inside. I'll see him alone. Buzz said they were going to Galveston this morning. I never thought he'd come back. Go on. Get in the house. Yes, ma'am. How are you? Hello. Oh, hello. I was just going around to the kitchen to look for you. Were you? Yeah. The boss in? Oh, yes. A little smorning. Gee, it sure is pretty here. You suppose she'd mind if we sat down? No. I, um, I thought you were leaving for Galveston this morning. Well, the boat shoves off this afternoon. You know, I kind of hate to leave here. Do you? Yeah. You see, last night I got to thinking, uh, look, uh, Mary, I, uh, will, uh... Well, uh, well, what? Well, Mary, we were leaving today and I was thinking, have you ever been out in my part of the country? Mm-hmm. Oh, no, no. Well, it's beautiful. A girl like you'd be crazy about it. And I was just figuring that if it's okay with you, well, more Hawkins could put you up until I got my house finished and, well, uh, I started to build it just before I left, just in case. And I thought that after a while, if you wanted to, we could change things around in the... That's her. That sounds wonderful, Stretch. Next summer, when I get my vacation, that's exactly where I'll go. Next summer, huh? Yes. We could have some more evenings like last night. I had such a wonderful time, didn't you? I was just telling the girls this morning.  The next blind date, huh? Yes. You don't know what trouble a girl has. Sometimes you meet the most awful people. Oh. I guess I was wrong. Wrong? Yeah. Sounded like you were on the level last night. Like it really meant something to you. I never had so much fun in all my life. So that's all it was. Well, I always knew that cow punchers were just supposed to be half-human, so, well, I guess I had it coming to me. You see, I don't go out with girls much. Generally, because I don't like the way they think. I joined this show because I thought maybe somewhere I'd run into one that didn't measure things by how many men she'd kissed in a week. I guess that sounds funny to you. Please stretch. Well, if you don't mind, I think I'll get going. Kind of feel like I need a bath. On second thought, I think you're the one that needs a bath. Oh, put me down! Hey, that's the right pretty swimming pool, isn't it? Put me down! Why, sure, Miss? Sure! Go along, Miss Mary. I had a fine time. Oh, my goodness! Help me up, hurry. He drew in the pool. I saw the whole thing. Katie, has he gone? He's gone in good riddance. Katie, Ellie, get me some dry clothes. Hurry. I've got to be at that boat. What boat? The boat for Galveston. I've got to see him again before he leaves. What? He threw you in the pool! I know, but don't you see, Katie, he was using manoeuvre number four. In just a moment, Mr. DeMille and our stars, Merle Overon and Jean Autry, return in act two of The Cowboy and the Lady. But first, shh, girls, just a moment, please. Mr. Rick, we're so excited. You are going to tell them about it, aren't you? Well, you haven't given me a chance. You see, ladies and gentlemen, before the program started, I showed the girls the lovely brooch, which the makers of Lux Flakes are offering right now to women all over the country. This one is entirely different from the Scarlet O'Hara brooch we offered last fall, and we think even lovelier. With the beauty. It looks like a real antique. No wonder it was inspired by the beautiful jewelry of the old south, and the original of this very brooch was worn in Gone with the Wind. My, I'd just love to have something as glamorous as that, but it looks so expensive with those five big simulated pearls and the big turquoise-colored stone in the center. And it has a safe to catch, too. You would expect to pay a lot for such a handsome jewelry piece, wouldn't you? It's almost two inches wide with a beautiful antique-style gold-finished setting. But it's yours for only 15 cents and the opening tab from a large-sized box of Lux Flakes. And because we know from past experience how much you're going to like these brooches, we're all set to take care of your orders promptly. But please don't delay. Get your order in early. Only 15 cents for that lovely brooch. Well, that's wonderful. I never heard of such a bargain. How do we get it? Well, first, you buy a large box of new quick Lux Flakes. They come in the same familiar box. Well, that's easy. We always use Lux anyway for our stockings, undies, and other nice things. Then, when you open it, tear off the opening tab of the box and send it with 15 cents and your name and address to Lux Box One New York City. Wait a minute, Mr. Ruick. I want to write that down. All right. Are you all set? I'll repeat it for you. Send the opening tab from a large-sized box of Lux Flakes and 15 cents in coin. No stamps, please. To Lux Box One New York City. Be sure to send your name and address so we can send your gong with the wind brooch right away. Now, with your brooch, you will receive an illustrated order blank for additional pieces. Ring, tendon, bracelet, earrings. All in the same beautiful design. All amazing bargains. This offer is good only in the United States. Act two of The Cowboy and the Lady, starring Jean Autry as Stretch Willoughby and Merle Oberon as Mary Smith. Completely under the influence of maneuver number four, the old-fashioned caveman routine, Mary Smith rushes to the pier where the Galveston boat stands ready to cast off. Pushing her way desperately through the crowd, she spies stretch at the foot of the gang plan. Stretch, wait. Oh, hello. Stretch, I came to see you all. No call for you to do that. But listen, Stretch, I want to explain. No need to explain anything. Well, I'm glad I met you. Stretch, come back. And by your spring, lads. Stretch! Sorry, lady, we're taking up the gang plan. I've got to speak to that man, that-that cowboy. You'll have to get on the boat then. We're leaving. But it's important. Listen, lady, on the boat or off. Which is it? On. Hello, Stretch. Hello. Excuse me, please. Please, Stretch. If you just let me talk to you. Well, I'm sort of busy right now. You've got to listen to me. Do you mind letting me in my room? No. There's something I've got to get straightened out. Please let me talk to you for a few minutes, and I won't bother you anymore. I guess I'll go up on the air for some fresh air.    What are you doing here anyhow? Dogging your footsteps? Well, watch your step on these stairs. You watch your own. Now listen, Stretch. Oh! Now, there you go. Didn't I tell you? I'm still listening to me. It wouldn't have happened. Well, I'm sorry. You heard that? I'll get over it. Look at my shin. Mary, you shouldn't have come on this trip. How long is it? About 68 hours. I suppose it will take me all that time to get myself straightened out with you. Yeah. You might lose your job. Oh, no. That'll be all right. Listen, Stretch. That's what I want to talk to you about. About my being a lady's maid. Poor lady. You'll have to dress yourself for a couple of days. I'll bet you'll be all tuckered out. You shouldn't talk like that. She's not so bad. You might like her. Uh-huh. I worked one summer on a dude ranch. I met plenty of her kind. Show horses. What are they good for? Except to dress up and look pretty. Give me a workhorse every time. Like best. That little marimine.  Oh, thank you. But a woman like your boss. Well, she ain't rigged up to carry her part of the load. The first time I've ever heard horses compared to people. Well, good horses are nice people. I've got words that go with it, too. Kind of a love song, you might call it. I'd like to hear it, very much. Let's go roaming around the rain. The night is soft and mellow. The moon is bright and yellow. Let's go roaming around the rain. Let's go riding along the trail. There's a booming desert roses blooming. Let's go riding along the trail. There's a pregnancy. Some of the bees. The rustling leaves. There's music to my ear. Come and rock me there. The song of the trees. The song of the breeze. It's what I long to hear. Let's go roaming around the rain. The lazy clouds are sailing. Let's go. Hey, too bad we couldn't give you a moon. Oh, the fog's all right. Well, maybe it's better. Night. Well, stretch. Well? I'll see you in the morning. Good night. Good night.  It's our last one. We can take another turn around the deck. But we can't do that forever. Yeah, I guess we can. You better go get some sleep. And you too. Yeah. Don't believe we'll close an eye, though. I won't either. We seem to be giving each other insomnia. What time is it? Oh, about 3.30. Say, that's the fishing boat out there. We're getting close to Galveston. I wish Galveston would stay away. We're going so on the count of the fog. I love the fog. It shuts out the rest of the world. Hey, you're shivering. I'll get you a coat. No, no, don't go. I don't want to be alone. Only take a minute. Please. All right. You know, it's wonderful stretch. You and I are miles and miles apart. And if you really knew me, you wouldn't like me at all. And yet, I'd rather be with you than with anyone else in the world. Isn't that funny? Say that again. I'd rather be with you than with anyone else in the world. You sure? Yes. You're not mixed up now? No. It's the one thing I'm not mixed up about. Come on with me. Where? We're going to find the captain. What for? The cause where I come from. When a man feels about a girl the way I feel about you. Well, I get married. Come on. Come stretch.  I do. Then I now pronounce you man and wife. Is that all? That's all. Good night. I, Mary, take these stretch as my wedded husband. For having to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and cherish till death do us part. But captain forgot to say that. Is this where we're going to live stretch? In a tent? This is it, honey. It ain't very much, but rodeos don't go in for fancy stuff. Oh, I love it stretch. And I love you. We won't be here long. We'll be living for the ranch as soon as I can quit the job. Hey, stretch, the chief wants to see you. Huh? Okay. Say, you don't mind being alone, do you? Yes, but I'm going to be very busy cleaning up here. Well, I'll be right back, honey. Go near here. Sure thing. Entrance to the rodeo grounds. Phone's on your left. Thanks, Vals. Katie, I can't hear you. What did you do? Your father's coming to Palm Beach. When? Don't you see, Katie? I'm... I'm married. We're speaking to Katie. Is there anything wrong at home? No. No stretch. You must be worried about your father and... and sisters. Well, in a way, mostly about father. You know, I kind of feel rotten about that. You should have thought of that last night. But I guess we didn't think much about anything last night. No, we didn't. Did we? Hey. Look, if, uh, if we could get him out to the ranch, we could take care of him somewhere. Oh, no stretch. Don't you worry about that. Well, I was just thinking, maybe that... maybe you'd better go back and see if he gets settled. Go back? Yeah. I was figuring that if you went back home and got them fixed up, well, you could be out to the ranch by Tuesday. Don't you think that's a good idea? Oh, stretch. It's wonderful. Well, come on then, honey. We'll get you out of here on the first side. I got it all written. Here, how you get to the ranch. Thanks, darling. Oh, you'll be crazy about more Hawkins. I'll get her to fix up a room for you till the house is finished. I can hardly wait. Boss to Houston. Yeah. All aboard. Here they go. All aboard. Mary. It's gonna be a million years, Sir Toosie. Bye. Stretch. Stretch, there's something. Something I ought to tell you. What? Well, it's about... All aboard. Bye, Mary. All aboard. Bye. All aboard. Bye, Mary. All aboard. Bye. Goodbye. Goodbye, Stretch. Can't throw a bombshell like that and then walk out on me. Uncle Hannibal, I've got to change my dress before Father comes. Who did you get married to? Uh, Palmer? No, no. A cowboy. Cowboy? Young? Yes. A young cowboy. See, that's wonderful. Is it? Well, unfortunately, I'm a show horse and he thinks I'm a work horse. And work horses are nice people. You didn't know that, did you? No. Are they? They're horses are nice people because they carry their part of the load. Oh, I'm in such a mess. Have you ever been so confused you couldn't make sense out of anything? I'm doing fine right this minute. Oh, I'm sorry. Oh, maybe I can help you. You met a cowboy young, married him and went to Galveston. So what are you doing here? Well, he suggested I come back here to my drunken father and four sisters. Oh! Well, that clears everything up. Oh, Uncle Hannibal, I can't explain it now. All I can tell you is I love him very much. I sort of have a feeling that's all that's necessary. Oh, Uncle Hannibal. It's Father. He's here. What did I tell him? Nothing. Your poor father is accustomed to being in the dark. But thanks for me, Uncle Hannibal. I've got to tell him sometime. Well, hello, Mary. Hello, Father. Good to see you. You look wonderful. A week in Palm Beach is just what you needed. Oh, yes. Well, my dear, everything's in excellent shape. Probably settle the whole thing before we leave here. I expect your help, of course. Well, many men and their wives are all here, and I want a dinner arranged for them on Tuesday. Tuesday? Yes, nothing elaborate, just enough to keep them in good humor. But the big thing comes later. You know who's coming down? Henderson. Now, we ought to have a reception for him. Father, I won't be here on Tuesday. I beg your pardon? I said I won't be here. I expect to be back in Montana with my husband. I'm married, Father. Oh, this is no time to be facetious, Mary. I'm not being facetious. I met him last week at a red-ear. He's a cowboy, Horace. A cowboy? You married a cowboy? Yeah. Why? This is fantastic. I can't believe it. A cowboy. And what's the matter with a cowboy? There's nothing the matter with a cowboy as far as I'm concerned. But what about Henderson? Can't I make you understand that without his support, my nomination is impossible? Mary, Smith, and a runaway marriage with a cowhand. That's going to look fine in print. Oh, stop it, Horace. Is there any reason why Henderson should find out? And how do you suppose I'm going to keep a thing like this secret? The boy doesn't know who Mary is. And if we keep our mouths shut, nobody will know. At least not until you get Henderson's endorsement. Once it's been published, he's got to stick by you to save his faith. No, I won't stand for it. Mary, you're going to stay right here, and I'll arrange to have the marriage annulled quietly. I'm sorry, Father, but if you attempt to do that, I should tell you to the newspapers myself. Oh. All right, Mary, if that's the way you feel about it, I hope you're proud of yourself. I don't suppose I should expect any further help, but I hope you have the decency at least to stay here until after the Henderson dinner. Is that asking too much? Of course I'll stay, Father. That's what you want. I'll stay and do anything you want me to. Thank you. Oh, Uncle Hannibal.  We have just heard Act Two of The Cowboy and the Lady, starring Merle Ovalon and Jean Autry. Mr. DeMille brings you Act Three in just a moment. The curtain rises on the third act of The Cowboy and the Lady. It's Tuesday morning. The day of Mary's expected arrival in Montana, and the Hawkins Ranch is the scene of feverish preparation. For the tenth time, Stretch bounces into the kitchen to pester my Hawkins. My Hawkins? Oh, Stretch, will it be, get out of this kitchen. I'm cooking. Now, wait a minute, Ma, this is important. What do you want? Well, it's about those, what do you call it? Those new curtains for her room. New curtains? There ain't gonna be new curtains. I'm not gonna make my house over just for her. Oh, come on, Ma. I wish you'd go and finish that house of yours and stop pestering me about new curtains. There ain't gonna be any. Hey, Ma. What is it, sugar? Oh, where do you want these new curtains hung up? Sugar, how many times have I told you not to come busting in here when I'm baking?  Sure, sure, sorry, Ma. No new curtains, huh? Well, well. Oh, leave me alone. Thanks, Ma. Say, what are you baking? Put that down, none of your business. Oh, something for Mary, huh? You think I got nothing to do but cook for Mary? Get out of here. Well, I guess I'll go over and take a look at the new house. Again? This is the fourth time today. The fifth, Ma. Hey, Stretch, telegram for you. Telegram? Here you are, just come. See, the train must be early, huh? What time is it? Half past eight. What you cooking, Ma? Just that pabolo. All right, all right. What about it, Stretch? Want me to get the buckboard out? No. What's the matter, Stretch? She ain't coming. You mean she... Oh, Stretch. Next week, maybe. A week after. She ain't sure. Well, I guess I'll run along. Anything you want, Stretch, let me know. Stretch, from what you tell me, I'm sure she wouldn't have to point you. Less than she couldn't help herself. A sentence holding her back there, maybe. Yeah. And maybe I ought to go back and find out what. Good enough to put my knees under the same table with a great Mr. Henderson? You look fine, Uncle Hannibal. They say this Henderson's quite a fellow. He's a magician. All he has to do is to wave the wand over Father's head and presto, he gets the nomination. By the way, when are you leaving from Montana? Tomorrow, the next day. The moment everyone clears out. Are you going to come clean with your cowboy? Even if I get tossed out on my ear, which I probably will. Well, for a consideration, I'll be there to catch you when you land. Evening, Mary. Almost ready? Ready, Father. Mary, I hope you realize that if Henderson gets an inkling of your marriage, it will be most disastrous. He has very fixed ideas and he'll be very careful about the years. I know, Father, and I'm sure everything will go well tonight. I did promise to do everything I can to help. What was that you were saying, Mr. Henderson? I was saying Smith that if all the young ladies in our country were like Mary, I'd feel a little more secure about our future. Our youth today seem to feel that life is not worthwhile unless it's lived scandalously. Oh, oh, yes, yes, of course. You agree with me, my dear? You're very kind, Mr. Henderson. Kate, yes? Yes, it's Mary. Didn't I hear the door? I'll go see Miss. How are you? Where's my wife? Your wife? Well, she, I mean... Oh. I guess she's upstairs. Will you tell her I'm here? Well, no, I can't. You see, she don't work here anymore. Well, where does she work? Where is she? I don't know.  Yeah, but Mary didn't talk much. She was very funny that way. You better go now. Goodbye. Now, just a minute. Is the boss home? Yeah, but... But then I'll ask her. She ought to know where Mary is. Now, wait. You can't go in there. Now, I'm gonna see the boss. Excuse me. Wait, please. Pardon me, folks. I didn't know there was a party here. Oh. Oh. Good evening. Are you looking for someone, young fellow? Yes, I was. The boss. Well, I'm the head of the house. Are you sure you haven't made a mistake? Yeah. A bad one. Sorry. Oh, wait, young man. Uncle Hannibal, don't. Will you come back here just a moment? Well, these men are politicians. They're always interested in talking to the man on the street. Sit down, young fellow. Why, certainly.  Why don't you?  Yeah. I guess maybe I will. Thanks. Uh, a chair here, please. Where are you from, young man? Montana. Montana. Ah, fascinating place. I've always been interested in the Lone Star State. You're thinking of Texas, sir? Well, why, of course. I always get them confused. Are you married? Yes, I am. I'm married. A lady's maid. She supports a father and four sisters. Uh, he should cling to a girl like that, shouldn't he, Mary? I, I think so. I don't.  Turned out that she was too good for me. Couldn't stand for me to meet her friends. On account of me being a cow hen, I guess. Since to me a cowboy ought to be as good as a lady's maid, I must remember to look that up and see what the book says. Well, keeping cows under control must be more productive work than hooking up a dress. What about the Indians? Who's going to fight the Indians? The cowboys always come to the rescue. They have a slogan, haven't they? We always get our man. Oh, no, dear. Those are the Marines. Wait a minute, everybody. Wait a minute. I want to get some advice from him. I want your opinion, young man. Judge Smith, our host here, is seeking the nomination for president of the United States, and he wants my support. Now, what would you advise me to do?  And the same goes for your smart-elite friends here. I beg your pardon. Do you think that...  Now, just a minute.  In the first place, I don't see where you get off picking anybody for president when you haven't the decency to treat a person like a human being.  Yeah, and what their needs are. And what you can do to help them. That's all that's gonna count in the long run. And if Judge Smith there wants to be president, he ain't gonna get very far looking down his nose at people and thinking he's better than they are. Abraham Lincoln didn't have to do it, and he turned out to be a pretty good president. Have you quite finished? Yeah, except for one more thing. I'd like to invite you all out to the ranch. And maybe we could show you something about decent manners. Good night, all. Wait, listen to me. I'm in a hurry. Please stretch, let me talk to you, please. A lady's maid, huh? You were bragging. Stretch. Well, Horace, I guess the cow hand sort of missed things up, didn't he? That was the husband, I presume. That's right. Like they always say, Horace, you haven't lost a daughter, you've gained a son. Well, he's your gain, Horace.  What's the matter? Firstly, I like the boy very much. And your snooty friends had coming to them, Horace. I want to speak to Mary. Then you'd better hurry before she leaves. She's leaving? Where? I didn't ask her. I figured that was your job. Mary, open this door. Well, Father. Where are you going? To Montana, I suppose. I haven't decided where I'm going yet, but it's definitely not to Montana. I can tell you that. Why not? The damage is done. It doesn't make any difference now. If you're thinking of Henderson, I can just show you. No, Father. Just for a change, I'm thinking of myself. I had a wonderful chance to be happy, and it's gone. Oh, I don't blame you. I don't blame anyone. But I can't go back to him now. He wouldn't have me, and I don't blame him either. Mary, I... You and I are alike in a lot of ways, except one. You had a great ambition, and so did I. You wanted to become president of the United States. And you wouldn't let anything stand in your way. I wanted to be a wife. That was my ambition.  I wasn't strong enough to fight for it. I'm not crying about it. Anything I get, I deserve. Certainly is nice to have you back, Stretch. Thanks. Quite a little work done on the house. The house? Your house. Almost finished, Stretch. Yeah? Well, that's as far as it'll get. I'm not moving in. Sorry, Stretch. Good morning. See, what's that fellow doing here? I don't know. Name's Smith. Been waiting for you since last night. Your, uh, Stretch Willoughby, aren't you? That's right. And you're Judge Smith, aren't you? Yes, I, uh... I was just looking at your truck garden here. And I used to grow tomatoes as big as these on my farm. You know, all the way in here on the plane, I kept thinking of something you said. People ought to get off their high horses. You're right. When you look down your nose, your viewpoints inclined to get blurred. Great many parents are that way. They'll get up on their high horse, I mean. They demand respect and sacrifice from their children, and the trouble is they forget they have to earn it first. See, I, I never earned it, but I got a great deal of it from Mary. All her life, she made many sacrifices just to safeguard a mad obsession of mine. Well, she doesn't have to do it anymore. I'm rid of my obsession. I've walked out on the whole business. You walked out? Not that I had to, but I, I realized it wasn't what I wanted after all, that I was getting on the plane to come here. It begged me to change my mind, but I refused. There are too many men in the country that are better equipped for the job. Besides, I found that Mary had an obsession that's more important. You see, she wants to live in Montana the rest of her life, and I doubt if even you could talk her out of it. Oh, will you, will you excuse me, sir? I got to get inside here. Just, just... Go right ahead, sir. Hey, ma, ma, ma Hawkins! Where are you, ma? Hey, Willoughby, what do you mean slam on doors like that? Well, where is she? She's here, isn't she? Where is she? Where's who? What are you talking about? Ma, it's so... What's that? The cake I was baking. Somebody slammed the door on the cake, so it... Oh, I slammed the door, Mary. Stretch. Oh, stretch. On my way out, I'll close it easy. You were baking a cake? Yes, I, um, I figured that there's something that even best couldn't do. Mary. Stretch, are you glad to see me? I, I know you aren't much on small talk, but couldn't you say yes? Mary, uh, I'm stuck from there on... Oh, stretch. Kiss me. Well, I guess I could do that, all right? Oh, stretch. Maneuver number five. Mr. DeMille returns with our stars for their curtain calls in just a moment. We hope you're enjoying tonight's program. If you have comments about the K and X drama hour lineup and would like a copy of our drama schedule, please visit our website at knx1070.com. Now, here's Mr. DeMille with our stars. We leave the cowboy and the lady home on the range and bring Merle Oberon and Jean Autry back to our microphone for a curtain call. Thank you, Mr. DeMille. It sure was an honor for me to work with Merle Oberon in your theater. Thank you, Jean. The only wrong note in the whole week, Jean, was the fact that you didn't bring your horse. I was anxious to meet him. Well, Merle, I reckon champion will be sorry, too. But he doesn't like this traffic around Hollywood Boulevard much. Every horse to his taste, Jean. You know, you and champion have given us some exciting times on the screen. And I've often wondered, what gave you yourself the biggest thrill? Well, sir, it wasn't in a picture at all. It was something that happened down in Oklahoma when I was a telegraph operator. One night, a stranger got off the train and this cow crossing where I worked and came in to send a telegram. I saw my guitar line there and he asked me to play it for him. So I sang a couple of songs and he joined in for a couple. And all together, I guess it took him half an hour to write out that telegram. Where was the train all this time? Well, that train never wasn't much of a hurry anyway, so it just waited. Finally, the man finished that telegram and he said, See you again, son. And he went out and got on the train. There wasn't much in the telegram. Just a couple of jokes addressed to a newspaper in New York. But that night, well, I could tell ever Brass Pounder on the line how I'd met Will Rogers. And Will had written his newspaper column between songs. What did he say when he finally did see you again, son? Well, he just said, Well, cowboy, I see you and that guitar made it, didn't you? Well, Mr. DeMille, I reckon that everybody would like to know what kind of a party you're having here next week. I reckon it'll be a bright one, Gene, because our guest of honor is Miss Shirley Temple. You'll hear Shirley, Charles Winninger and Gene Lockhart in Captain January, a story of a bluffle lighthouse keeper and the little girl named Star, who was the light of his life. Shirley's performance in the 20th Century Fox picture is a brilliant memory. And next Monday night will be a memorable night for this theater when we present Captain January. And with Shirley Temple, I think you'd better get ready for a capacity house. Mr. DeMille, good night. So long, everybody. Our sponsors, the makers of Lux Flakes, join me in inviting you to be with us again next Monday night when the Lux Radio Theater presents Shirley Temple, Charles Winninger and Gene Lockhart in Captain January. This is Cecil B. DeMille saying good night to you from Hollywood. Gene Autry appears tonight through the courtesy of the makers of Double Mint Gum. He is currently seen on the screen in the Republic picture, Melody Ranch. Merle Oberon is now making the picture affectionately yours with Dennis Morgan at Warner Brothers Studio. Heard in tonight's play were Eddie Waller as Hannibal, Lou Merle as Murray's father, Gloria Blondel as Katie, Fred Mackay as Buzz, Werner Felton as Ma Hawkins, Arthur Q. Bryan as Henderson, Janet Waldo as Ellie, and Ralph Sedan, Charles Seal, Joe Duvall, Stanley Farrar, and Julie Bannon. The brooch offered you by the makers of Lux Flakes was designed from one worn and gone with the wind, the Selznick International picture produced by David O. Selznick and released by Metro-Goldwyn-Mayer. Our music is directed by Louis Silvers and your announcer has been Melville Roy. This is the Columbia Broadcasting System.


This is again a buzz about space, largely due to the three billionaire kids, Amazon's Bezos, Virgin's Branson and Tesla's Musk. Musk and Bezos are talking about colonizing Mars and outer space straight out of science fiction, popular when we are growing up. In this episode of The Science Show, we are going to look at not space or Mars colonies, not space science fiction, but what makes going to outer space possible? Rockets. Yes, the rockets, the kind we played around as kids. The same principle that makes those rockets possible also makes it possible to have designs and space exploration. We all think Americans won the space race as they went to the moon. It seemed like that was a race and there was only one winner, the United States. And it was over with Apollo astronauts landing on the moon. What about the rockets that still power all our satellite launches? What about the rocket engines that powered these rockets? Are you aware that most rockets that the US today uses to power its military and civilian space launches use Russian rockets? If the US won the space race, why does it use Russian rockets today? All of which came out of the Soviet space program. As intrigued by recent MIT review that talked about the decades old Russian engine with which Musk and Bezos engines are competing. So let's look at those engines, those rocket engines and let's start with the rocket engine RD-180 that has powered the US Atlas launch vehicles from 2000 onwards. The Atlas rockets were manufactured by Lockheed Martin, now by United Launch Alliance, a joint venture between Lockheed Martin and Boeing. Where did this RD-180 rocket engines come from? Why did the US switch from their indigenously designed engines to RD-180? The origin of RD-180 is an older engine, RD-170, which was developed for the Soviet-planned Buran space shuttle. RD-170 was to power the energy launch vehicle. The energy launch vehicle made only two flights, the last one in 1988, shortly before the Soviet Union collapsed. It was followed by Yeltsin's kleptocratic years that saw Russia become virtually a vassal of the United States. Its state entities were dismantled and its assets sold. The company that survived the Yeltsin years was NPO Enerjomash and it was one that sells the RD-180 engine to the US. These rocket engines were developed in the 80s and are still in use today by the United States military and NASA. They are almost 30-35 year old rocket engines. Both the US and the Soviet Union built on the V2 rocket that Germany had developed and used in the Second World War. Warner Von Braun, the head of the German program, brought over a large number of German engineers to the United States. Von Braun worked on the US Apollo Moonshot program as can be seen here. For those who remember Kubrick's film, How I Stopped Warring and Started to Love the Bomb, the character of the mad scientist wanting to build bigger and bigger bombs was based on Von Braun. The Russians also had German scientists working on the rocket program, but they were able to radically improve the V2 design and develop better rocket engines than the Americans. To compare various rocket engines, let us look at what happens in a rocket engine. When you have what is called an open cycle rocket engine, this has fuel and liquid oxygen. These are the two things you need to go to the combustion chamber for it to fire and the exhaust gases coming out of the combustion chamber leaves at a certain velocity and that is what powers the rocket forward. When you want to pump fuel and oxygen at a higher pressure, if you have higher pressure you get a better and more efficient engine. Then you need to provide pumps which will therefore pump at a higher pressure both fuel and oxygen into the combustion chamber. Now for powering those pumps we use a turbine. As you can see the open cycle rocket engine, there is a turbine which powers both the fuel pump and the liquid oxygen. So what powers this turbine? We take a little bit of fuel, we take a little bit of the oxygen, we fire it in a pre burner and the exhaust gases of the pre burner expand in the turbine powering both the two pumps. Now this exhaust from the turbine in an open cycle rocket engine is exhausted into the atmosphere or outside the rocket which means whatever unburned fuel is there and whatever oxygen is left after the combustion both get exhausted. If they go out of the rocket then what happens is that we lose some fuel and some oxygen which could have entered the combustion chamber and participated in the rocket propulsion. This is where the Russians and the Americans parted ways. The Apollo program which was the American moonshot program was powered by Saturn rockets. These Saturn rockets were quite large, they were very impressive. They had high lift capacity but that was not an efficient engine which they used. The rocket engines used were essentially open cycle with the losses we talked about. The Soviet engineers invented something clever, they designed something more clever. They developed what is called a closed cycle rocket engine. This is what we have in front of us, a closed cycle design in which we have the same configuration as earlier which is you have liquid oxygen pump, you have the fuel pump being rotated by a turbine, this is a common shaft that is because the fuel used and the liquid oxygen used have roughly similar specific densities that you could use a common pump. This turbine exhaust as you will see was fed back into the combustion chamber. While it was fed back into the combustion chamber, what was done was all entire oxygen which as you can see which is being pumped was fed to the pre burner through the turbine and it was fed into the combustion chamber with some of the fuel which might or might not have been burned completely. Now, why was oxygen rich exhaust of the turbine used in this way because that meant that the fuel was completely burned but it had a problem. The problem was metallurgy. This required relatively high sophistication for the metallurgists to try and see how this extremely hot gases with oxygen would not cause melting of those components which came in contact with it in the combustion chamber. Remember this is like a oxyacetylene torch through which we cut steel. So, that is what we are really seeing here when you talk about the exhaust of this turbine entering the combustion chamber. This was a difficult metallurgical problem with the Soviet engineer solved. The Americans did not believe that this was a solvable problem. So, they moved to a different configuration which is what we will show you now. They used what is called a fuel rich stage combustion rocket engine. Here and we have the first the simplified version that turbine pump configuration is all of it is same and we are seeing the turbine exhaust which is now fuel rich does not have enough oxygen to burn completely entering the combustion chamber. That means unburned fuel is now being pumped in the combustion chamber which means that it will be completely burnt in the combustion chamber itself when it gets the liquid oxygen or the oxidizer which is coming otherwise which is being pumped into the combustion chamber. The problem here is that if we use a fuel which for instance is say a high form of what is called kerosene or P1 fuel if we use any fuel of that kind then you have the problem or what used to be called glycol based fuels then you have the problem that we generate soot and if you generate soot it gums up the piping the valves and other stuff and that makes it much more difficult. So, what they had to do in order to avoid this kind of soot exiting the turbine or the pre burner in this case was to change the fuel. When you change the fuel to something like liquid hydrogen which is what they did then of course this problem is avoided but you have a different problem that the hydrogen fuel has a very different specific density the liquid oxygen therefore you need a different pump therefore you need also two turbines not one. This is what the Americans did for their fuel rich stage combustion as you can see their fuel rich stage combustion becomes more complex because it now uses two pre burners two turbines and two pumps and this was the more difficult engineering feat that they had to do because they did not solve the metallurgical problems which the Soviets had solved by which with better metallurgy they could handle the oxygen rich exhaust from the turbine. Now, this was the major difference between the two what happens with in this case is that oxygen rich stage combustion is much more efficient in terms of its bang for the buck how much can certain amount of fuel provide in terms of impulse and we are not going to the details of that but the same size with the same amount of fuel you seem to get better efficiencies and a better bang for the buck. This is why when you come later to what the Americans were looking for for their engines rocket engines to power their rockets they found that the Russian RD-170 was a much more powerful engine rocket engine but unfortunately for them it is too big what EnergoMash did for the Americans was to split the RD-170 which is what the Energia rocket launch vehicle was it had four compartments the split into two compartments and that is from RD-170 the transition to RD-180 and the RD-180 is the one which was then used for a huge number of launches the American military and NASA carried out the Atlas III Atlas V engines rocket engines then became the Russian RD-180 engines that is one part of the story that is the second part of the story which is even more interesting you had another group in the United States which is also sending rockets they were planning to send for the space shuttle the basically rockets which are called Antares rockets now this is Northrop Grumman which were at that point developing the Antares rocket in the 90s they had come to Russia and they heard about the NK-33 rocket engine now NK-33 was a part of the moonshot program of the Soviet state at that point of time this was 60s now that was called the N-1 launch vehicle that didn't work very well in fact they were trying at a very short compressed period to try and develop their own moonshot program which they again abandoned once the Apollo program successfully put the Americans on the moon they actually started they had started later but what they had is this NK-33 rocket engines which also had the same property that we discussed earlier they were oxygen rich they were that way relatively more efficient and they handled the metallurgical problems of oxygen-rich combustion as well so the Americans heard about it they didn't actually believe it these engines however had been preserved 40 of them were kept in a quasi mothball state under atmospheric conditions air conditioning and so on and then the Russians said here we had solved the problem and if you want you can take one of them and experiment on it and see whether it works or not the Antares group of Northrop Grumman found that it actually worked they did experiments on it found that yes what was promised was true it was a more powerful rocket than what they were using and this was something better than what they had planned for and it was off the shelf available of course 40 year old engines so these 40 year old engines powered the first Antares rocket launches and test bench results were there after four of these engines were used one of them blew up then of course as you and cry why are you using 40 year old mothball engines reconditioning them and trying it like this so they had to give up that attempt but the point is the N-33 rocket engines worked even 40 years after they had been mothballed Antares switched their rockets the rocket engine then was not the NK-33 as they had tried they switched to RD-181 now RD-181 is again derived from RD-180 which you've already seen and discussed for the Atlas launch vehicles except instead of the two chambers that we talked about it has one chamber so RD-181 is effectively half of RD-180 just as RD-180 is half of RD-170 so this are the progression of Russian launch engines rocket engines which Americans have used and continue to use even today except for the fact that we have what is now a renewal of a kind of Cold War between the United States and Russia following what would be called the Crimean Crimean Peninsula issue where United States objects to the referendum that took place in Crimea by which Crimea joined Russia now without getting into the geopolitics of this today because we are really talking about engines there was a then a move that the American space program should decouple from Russian rocket engines except for the fact there was no rocket engine readily available so there was a talk about not using Russian rocket engines but trying to develop their own rocket engines and also a talk about manufacturing RD-180 in the United States itself so it is theoretically possible given the fact that transfer of technology agreement had been signed for these rocket engines which were coming from Energomash to also possible to be developed or manufactured in the United States what they found was the cost was too high that the investment they would have to make to manufacture wasn't really worth it so the hunt started for alternate engines and this is where Elon Musk and Bezos come in they would like their engines to be used they also have been funded in different ways both Bezos and Musk have been funded by NASA and the US military for developing alternate rocket engines and these are the rocket engines that today are competing with the Russian engines even today the Americans continue to use the Russian engines by 2022 they will stop using Russian engines for military launches which is basically the programs which put satellites in the sky of course you have a huge range of satellites the military uses and Russians are also not comfortable about this they have said they would like to ban the use of their rocket engines for putting essentially military's hardware into space so from both sides there is now a decoupling on the issue of military launch vehicles what we are now seeing is the B-4 engine of Bezos as well as Musk's various engines the Raptor engine being the largest of the family which are trying to compete with the Russian engines yes probably by 22-24 the Russian engines should be slowly phased out of the American space program particularly as NASA is funding now both Blue Origin as well as Elon Musk SpaceX for their rocket engine we have to now see whether when the Americans decouple completely from the Russian engines which they probably do in the next two to five years whether Musk's Raptor engines and the other SpaceX engines as well as Blue Origin's B-4 engine can successfully replace the Russian engines so we will have to watch and see how this competition today develops in space


Tom here from Lawrence Systems and this is a Raspberry Pi 4 With nothing on it. So it's not interesting yet We're gonna make this a much more interesting Raspberry Pi 4 and the goal of this video is to show you how to get started with Kali Linux as a Reconnaissance tool now the business use case for this is you want to be able to take something that's relatively inexpensive I mean I could just drop my laptop off at a clients But I'd miss it and I like this laptop and it costs a lot more than this Raspberry Pi And if you have a client where you need to do some assessments you need to do some discovery you need to Be able to access their network easily without modifying firewall rules because this is kind of an initial When you're working with clients or sometimes you you know don't have access or have not changed out the firewalls and got everything set up So you want something fast and easy to deploy? That's what this is We're gonna show you how to load Kali Linux We're gonna show you how to set up X to go on a Raspberry Pi 4 running Kali Linux And we're gonna top it off for remote access with zero tier now I've done some in-depth videos with zero tier But I'm gonna cover the basics here and how to get it set up how to join your computer to the network And once you have it joined to the network with zero tier it doesn't really matter where it is That's kind of the whole fun part of how this works is no matter where you deploy this It doesn't need any extra firewall rules changed on their network as long as the Raspberry Pi can get internet It'll go out to zero tier it'll get connected and then you can connect it even if their IP address changes It doesn't matter it's going to work and that's what we're gonna walk through today So let's get started but first if you like to learn more about me or my company head over to Lawrence systems calm If you like to hire short project There's a hires button right at the top if you like to help keep this channel Sponsor-free and thank you to everyone who already has there is a join button here for YouTube and a patreon page Your support is greatly appreciated if you're looking for deals or discounts on products and services We offer on this channel check out the affiliate links down below They're in the description of all of our videos including a link to our shirt store We have a wide variety of shirts that we sell and new designs come out. Well randomly so check back frequently And finally our forums forums.laurancesystems.com is where you can have a more in-depth discussion about this video And other tech topics you've seen on this channel now back to our content Now as I mentioned raspberry pi is relatively inexpensive We're doing this on a raspberry pi 4 4 gig started kit this technically would work probably on a raspberry pi 3 But hey the 4 is out and it's relatively inexpensive And this whole kit including the sd card and a fan and heatsinks that I put on it Is all of $99. So this is a pretty expensive pretty inexpensive box Especially compared to my laptop and it does run kelly linux perfectly fine Now what is or where do we get kelly linux kelly linux by offensive security is a really great linux distribution Which i'm so happy they've really got well maintained arm versions of as well Not just x86, but arm versions that work on things like raspberry pi It's basically an all-in-one Linux tool kit with lots of great tools on here We're really just going to scratch the surface when it comes to doing reconnaissance and just show some of the basics On here towards the end of the video, but at least it'll get you started if you look for any other Things on kelly linux you'll find it's a really amazing tool set on there for doing not just some basic reconnaissance But even some advanced from mobility scanning road access and maybe some you know Real pen testing you could do all from this box, but this at least will get you started with it Now we have here the different images You should be able to modify my instructions here to work with one of these other systems if you want Specifically though, we're going to download kelly linux for the raspberry pi the 64 bit one right here Now how do you get it on there that part's pretty easy? And basically if you're running it on linux like am you can just get this image file and copy it to the sd card Now this kit that i referred to comes with 32 sd card That's actually plenty for what we're going to be doing at it It really doesn't take up a lot of space to get this loaded Now in case you're running windows i'll leave instructions on this right here There is an instruction for making kelly bootable on a usb drive for windows And it shows how to use this tool here called etcher, which is free So all of this doesn't cost anything in terms of the software wise once you have the hardware everything else is just your time It took to learn this so it's only you know expense so to speak that you're going to be putting into this So you can get the free etcher tool burn it to or flash it to i say burn because i think of cds But you could just flash it to the drive and they have the instructions here now one of the first steps So once it logs in is going to be this right here And we're going to talk about that because housekeeping is important Especially when you drop these things off and what you don't want to do is load this up with just the default image and Drop it off because it's got the default username of kelly and password of kelly along with Predefined keys on it which would be easily accessible by someone else if they wanted to take it over So when i talk about the housekeeping part don't kind of skip over it because you want to jump ahead Do take the time to do that because sometimes these get dropped off at clients And maybe you're trying to do a discovery and maybe they have a threat actor on their network And now you just gave them a tool in the middle of their network with default credentials So before you ever deploy these in any environment, please do the little housekeeping steps And we're going to jump into those next now assuming you did everything right and you flash the system Flashed a little sd card. This is what your boot screen should look like if you have an hdmi plugged into your Raspberry Pi So pretty straightforward. It's going to go through it boots up And we're going to get a login prompt and a graphical one at that in just a moment All right. Now we're at the login prompt now from here. We're going to type in kelly And we're going to type in kelly again, which would be the default password I already changed it. So yes, I did type in a longer password And now you'd be into the ui now, that's fine. And from here you can open up a terminal You can look up your ip address. Um, I already know what the ip address is Is I seen it register on the firewall and looked at the thtp table So I know what the ip address is and we're actually going to go and ssh into the box That's the way I'd prefer to do it from here on out and manage it And we're going to show you how to get back to the graphical ui because ideally if you're deploying this At a clients, you're not going to have an hdmi and an easy access to it So we'll switch over to ssh and then show you how to get back into the graphical part from there Now as I said, I already know the ip address. So we're going to ssh in kelly at 192 1683 Dot 180 that was with my firewall Handed out as an address to this through the network interface. Well, technically before I ssh in I usually do ssh copy id Now this is another assumption and you can you know pause right here I don't have a video on this but you can go look up how to generate ssh keys If you do this with ssh keys, you're going to be that much more secure This is something I recommend doing but if you did want to just use username and password to log in That is completely possible and you can kind of skip this step But if you do ssh keys, it's that much more secure because no one can brute force an ssh key the same way Or as easily I should say as a username, password combination So we'd copy our id it would prompt us for a password It copied my ssh keys over to the kelly linux install because I already had them on here It didn't prompt me for the password again. But once you've done that You can just go here then and ssh in And you're in now housekeeping As I had mentioned right here sudo rm Etsy ssh ssh host then sudo dpackage reconfigure open ssh server and restart service Now the reason you do these is so you can Go in and delete those static keys that were generated that come as the default keys on all of these instances So we've got go over here. I'm not going to run those commands as I ran them But just take the time to do those right there the next little bit of housekeeping is provided you installed your ssh keys is sudo Vim or your editor of choice if you're preferred nano, I highly recommend learning vim. It's worth the time ssh ssh dconfig Don't forget the sudo and right here the default is password authentication. Yes, and we added password Authentication. No, please note that p and a are both capitalized. What that means is that only Keyed authentication can occur So we can log in with a key, but there is no way to log in with Username password before you do this and before you change that setting do make sure that you can log in like I did and that it can be Passwordless login through the keys like this. So ssh kelly and it logs in do that before you set it once You know, you have the keys working then set it in a way you go So that part is done as far as ssh keys You've cleared the old ones you've now if you've done this properly you have your ssh keys installed So you can easily just log right into kelly. It's just just make your life a lot easier when you're setting this up Next step zero tier and zero tier is a really important piece of this I'll leave a link to this because if you go to the zero tier download page, you won't see listed exactly the different compilations for The arm processors, but they do have them They're just specifically right here and this is the one specifically you want to use that will work with kelly linux This is something i've covered in a previous video, but i wanted to make sure was uh, you know It's important that you get the right one This is the arm 64 and i'll leave a direct link to this in My forum post of each of these commands so any of the commands i type in here I will make a list of in the forum post so you can just copy and paste them in so you can get this file But this is the zero tier one arm 64 So we'll just do a quick copy link address And then we would just do a w get And install it now i've already downloaded this file But that's all you got to do is to get that file then you would do sudo d package pkg dash i And then you would do zero tier 64 dev This will install that particular package because this package is not available through your normal apt kits repositories That's where we had to download specifically the dev package But once it's installed we can jump right into zero tier as a matter of fact put sudo in front of it Because it's controlling things at the network adapter level. It does need sudo access zero tier cli Put in the that and now we can list the display. So let's say info It is online and ready. So how do we join a network? That's actually pretty simple So we're going to go over here to zero tier And this is my zero tier youtube testing network id And i have an entire video which i'll link to where i go in depth of all the amazing features that zero tier has But essentially it uses what they call udp hole punching So you do not have to open ports, but you still get access to your devices that are all on zero tier Even when they're on separate networks, which is obviously an important part if you want to take this To a client to do some reconnaissance So we go here to a network id and we're just going to copy it And we're going to go down here and we see my laptop is already in here And it's actually the only device in here. So then we go back over to the terminal And we want to zero tier we just type in the word join so sudo zero tier cli join And paste that in Join okay That's really it. So now if we go here zero tier peers We can see it's now joining some of the network. That's exactly what we want. So we can go back over here to zero tier again Wait for the page to refresh All right. Now it's showing up. So we're going to go here check the box And we'll give it a name of kelly pie And this one's actually going to go to my house for the testing so Uh tom's house. Whoops There we go. That's where it'll be for testing. Just go in there type it. It's saved now here Is the new ip address of it And what this does was zero tears it adds another network adapters another we're joined and we have an ip address We can go to ip space a And we can see That ip address and the zero tier adapter now from here on out We're going to start accessing this from this ip address. So if we go over here And we type ip a on my computer. We see that my laptop has a zero tier ip address of this But that means we can go here ssh kelly at And now i'm logged in via that ip address So no matter where I go with this raspberry pi or my laptop as long as they both have internet access They will start talking to each other over zero tier. So even when I move around with my laptop I don't have the vpn back to the office or anything like that I can just take this my laptop has internet And then i'll actually going to take the raspberry pi for the next part of this video We're going to take it to my house and get it over there so we can access it or anywhere else We take it and i'll always use that ip address zero tier statically assigns an address an id to it So it becomes unless you change it the address it always receives whenever it gets internet So no matter what ip address is handed from whatever network it's on it always has a backup So to speak a secondary i address that matches that zero tier address Now one last thing we're going to do though before we Get rid of this raspberry pi and put it on another network. We're going to sudo apt-get install x to go Server now i've already got it set up on here But there's really not much setup you just do apt-get install x to go server That was it That's all you have to do to get set up now I have a previous video there were a lot more instructions a new version of cali linux here in august of 2020 Is a lot More updated and didn't have to have any extras and that's going to give us the ui access we're looking for so We're going to we'll go ahead and test that right now and we're going to go over here We're going to go open up x to go Now i already added this as a new session with that same ip address But we're going to edit and show you what the session looks like Is you create it i called it cali pi there's that ip address because we're going to access it from its zero tier ip which is static Login username is cali ssh port is there try auto login via ssh keys Now the reason that box is checked is because with the auto login It's going to use my key files to automatically log in if you previously Didn't have your ssh key set up and you skipped that part earlier in a video Then no problem you if as long as you didn't disable password login You could put a username and password combination to log into this The last little piece you have to do is right down here The desktop that's installed is xfce you can install other desktops if you want But i found it xfce works perfectly fine So there we go xfce hit okay. There's really not anything else we need to do in here But click it for connection. It's going to use my keys my ssh keys So it's not going to prompt me for a password and it's going to connect here in a second Here's x to go And it's loading up a desktop session Now i can even leave i can open up things and leave this desktop session running something i can Kick off utility i can open up a browser We'll actually open up a browser right now and i'm browsing from that machine It's you know, basically a terminal or remote access to it So here it is because some of the kelly training docs and if we were to close this He'll take a second to close But we didn't log out Then we go back over here Go back in again And you'll see it'll be right where we left off So if you do kick off something you can use the ui to Be inside that network now another advantage of using the ui because this is Remoteed into another network right now. We're on the same network for the next part of the video We're going to put the raspberry pi somewhere else. I'll still be here in the studio But i'm actually going to drop it off at my house and when we do that We're going to still be able to get to the ui and everything we need to do So we still have access to any graphical utilities we want if we wanted to especially things like wire shark I find wire shark is a whole lot easier to use through the ui at least you know if you want to do a lot of Filtering and stuff like that. It's great to do it here. Oh, and if you're wondering why it's so small Don't worry. We can fix that. I just left it at the default 800 600 But yes, it will go bigger. So we'll close that now. We have wire shark if you wanted to use this Yes, you can use wire for shark from the command line I know someone may point that out, but we have full terminal access, but i'll admit Since you are looking at a terminal through graphics right here, which is okay I still prefer the command line here When you're in it because well, you can use things like tmux and then start a session start a process Leave disconnect close my laptop and still resume that session later I've got a video where I've talked about tmux as well But we're going to go ahead take this over to my house drop it off Show you how to get it connected and then we're going to do some scanning on it to show you how to create a network Enumeration report and kind of start diving into how this actually works and what it looks like in practice now that we've gone through the setup So it's the next day for you. It's just a jump in the video But for me it's tomorrow and I have my coffee because it's the morning and I have the raspberry pi installed Now all's I did when I took this to my house Plugged it into the network now a couple little things Make sure you have permission to scan a network before you go dropping off a raspberry pi That has not gone well for people who have without permission plugged into random networks So it is important you have permission and of course I have permission to do this because it's my house Second the only thing I did was plug it in. I didn't look at the ip I didn't plug a screen into it. I just turned it on with a network jack plugged into a switch So that's it. I don't care what ip address it gets because we have zero tier installed And probably within only a few minutes it popped up in zero tier from the time I turned it on to the time It was active and connected So as long as it gets an address and can get to the internet It'll then get to zero tier and then we can access it So we're going to switch over here and look at the zero tier control panel And we see my laptop is online and I've got my Office ip address blurred out, but I'm leaving public my home ip address, which is 6 9 14 103 125 So this is the kelly pi at tom's house and once again even though it's at a completely different location It still gets assigned the static address of 10 147 17 dash 94 so we'll switch right here ssh and to kelly at 10 dot 147 dot 17 dot 94 And we're in so let's look at what ip address it does have so now we can go in and look not that we Need to know except we want to do some reconnaissance So we see the eth zero is plugged into 192 1681 Dot 124 so we have nothing on the wlan We could always start scanning the wlan and start messing around with that if we wanted to as well If we wanted to you know, see what wireless networks We'll see that for another video But in terms of here's our zero tier connector has that same ip address Which allows us to get in which means even if my public ip at home changes because well it is dynamic I don't have a static one at home And if I move this to another network to do another reconnaissance Well, same thing. I just keep logging into the same ip address. This is kind of the beauty of how that works So now let's actually enumerate my network So we're going to go ahead and do that with Tmux first and why am I doing the tmux? Well, then we can close my laptop and move on I've got a whole video I'll link to about how to use tmux, but what tmux essentially allows you to do is detach and reattach from sessions and so We'll go back here tmux. I think it's l ls and it shows us that we have one tmux session running in the background And watch this if we exit And go back in That session still exists and let's reattach to it And the reason that's going to be important when we have here is because when I kick off this command It's going to take a little while. Well, not a little while for you I'll skip ahead in a video in terms of waiting for the enumeration to occur But I do recommend that you run this through some type of terminal session that way if you're waiting two or three hours If it's a large-scale network for something to complete that you're not You know just hold on I got to keep the session open because if the session breaks and you kick it off It may not complete But if you have it spawned in something like a tmux shell It's going to have no problem You can disconnect for it even if I abruptly disconnect from it It will automatically go back in and I can reattach that session and pick up where I left off And the processes I kicked off will keep running so I can see the results from them So let's go ahead and Use nmap to enumerate my network and I'm going to leave these commands once again as I said over in my Forums so that way you can just copy and paste them because there's going to be kind of a long command We're going to put in for this Okay, so here's the command we're going to use and there's a lot of different ones you can use with nmap But this is kind of a nice basic discovery script that we'll go through and as long as you have both nmap installed And the only thing you have to add because kelly comes with nmap has this xlst proc Tool apt to get installed at no big deal there and what this allows you to do is nmap dash dash script Discovery is a script you're going to run this is built into nmap We knew the network because we typed it ip space a and we've seen it was a 192 168 network So we'll say 192 168 1 slash 0 slash 24, which means scan all hosts on that segment of the network if dash x Oh report dot xml and then we have this what this says is once that's done and we generate report dot xml Then we want to run this tool against report dot xml. We're going to stick a date in front of it We're going to call it the tom house report dot html And what this is actually going to do is take a little while to run and give us a nice html report of all the hosts that discovers ports open and this is the You know real important step is the discovery of what hosts are on a network Especially when you're doing this for business purposes and you go. Hey, I got to start enumerating. What is on this network? What are all the devices? What are all the things that need to be taken care of or what are the random things that are open and Beyond scope of this particular test you can take the same nmap and this takes a little bit longer nmap has some basic vulnerability scanning Abilities so it can then take after you find all these ports Then you can maybe do a more intense scan on a couple devices for vulnerabilities and cbe's If you want to kind of keep drilling down into a network for discovery and you can all do it from the Strasbury pie. I forgot to put sudo in front of it. So I kicked that off and here's what I'm talking about So if I were to close this and we'll just go ahead and Close it real quick Then go back open up a terminal session make the screen a little bit bigger here for you ssh back in List out the sessions for tmux and we'll just do there's only one session. So we'll just attach Right where we left off. It didn't stop this from running So it's still digging through finding the mac addresses Doing some multicasting if there's anything ipv6 on there. So this script's going to take a little while to run But we're going to go jump ahead here in a second to it being finished All right, it took about 15 minutes for this to run and now it's complete So we now have our report xml and this right here, which is important the tom house report dot html Because while we can go here and we're going to go ahead and open up the report And it's got lots of data and it's all a nice xml format. So you can import into something It's still not pretty if you wanted to just easily have something that can be presented to a client or just for you to look at To get a nice pretty report now a couple things we can do one We could just grab that report and bring it back over to my computer and view it or as I mentioned earlier We have x to go installed and same ip address the kelly at 10.147 1794 We're going to go ahead and just open this up with x to go and part of the reason I put x to go on here So we can get to the graphical UI if you want to run tools like wire shark Also to show that it does work across internet connections and works quite well So I'm going to take a second to get connected and spawn the screen. It's actually not an internet speed connection It's how fast a Raspberry Pi can spawn a session because this hasn't been spawned before so it's not reconnecting to existing one There we go And we're going to go here There's the toms house report and we'll open up in a browser and show you what it looks like And we'll find all the devices on my network And there's a lot of things on my network well A decent amount of them I should say I know a bunch of them are chromecast So let's scroll down the report a little further ports that are open Flags it found uh, oh this is interesting it dug into quite a bit This little device that I have here, which is another Raspberry Pi. I've talked about that project running the MI so it's a Raspberry Pi camera system I have on there So it went and explored all the different Things you can do on there to tell me a lot about it One i2-168-106, what's this? HTTP chrono request times Interesting, so there's some of the ports that are open on this. I'm going to guess that's a chromecast But you have a lot of detail that you can start going through you have a good understanding of what's on this network now And what might be interesting to further investigate Now among these and let's actually scroll back up towards the top Because we're on that network. We can also start logging into them So let's see what else do we have here 192-168-1.4 or what else is there? Wow a lot of stuff. Well 192-168.1.8 Let's see what's on that one Okay, we got ssh open we got the ssh host key It found a lot of different assets that were publicly somewhat publicly available to start identifying what this is And it's a free NAS. I already know because this is my network But you can see how it really goes through and takes the time it starts diving into these Then from there we can launch further intelligence reports and start digging further into Everything on there and of course because we're on that same network 192-168-1.8 and we can start logging into things from this network So now we can start digging further playing with the ui's etc etc So it's really nice having the ui start really pentesting something and it's all easily available here and the same thing with the Sessions if I kick something off that's going to take a while and I well I'd want to close my laptop and move on We'll close this Now that the session spawn will just go ahead and Close that go back over here next to go And open it back up actually you want to change the resolution to Something a little bigger. This looks a little bit better Quit opening up at 800 600 reconnect to it And we're right where we left off We have the login screen that we left it off on and I can Pick up wherever left off or if I had something like and we'll pull up wire shark for an example again Maybe you want wire shark to keep doing something in the background Authentication is required but the authentication in And maybe we want to do some sniffing on this particular network or there is the option here So we have the a bluetooth monitor. So if there's bluetooth devices in the area you want to look at There's a lot you can start pivoting from and doing here and it's all facilitated of course because The zero-tier connection allows us well wherever this is or if their ip address changes No worries. This will always essentially have that same static ip address We can go into and even if it changes mid session the sessions will always end up at that same place So I can always reattach later even if it's a week later. It doesn't really matter Now the couple final things that you may want to consider that goes a little bit on the scope of this But it's something you can load on here are things like sync thing and you can use that same ip address So maybe you put a fleet of these out there and zero-tier does allow for free up to 100 devices So you could have a handful of these raspberry pies give them all nice names for which site they're at Then set up something like sync thing on there for each one of them And what that would do is anytime these reports are done You could then have it tied to whatever internal device you want this tied to such as my laptop and those reports can just show Up here. It's also handy if you have scripts you want to deploy that are common across all these You could always set up sync thing drop that script in there and then log in remotely to execute them And if you want to make this more automated I have a video on ansible as well where you could set up all these in a list with ansible And then you could maybe run the same scan modified it of course to match each network And build out different functions that way so you could say I want to run this command against these group of raspberry pies At these particular clients or just kick those scripts off at some type of interval that you want and then Have sync thing drop all the reports back over here when they're done You'll just see them show up and you'll have all your reports and you can even go further and automate You can see how this can keep building into a pretty well Rounded tool set for relatively inexpensive building out these sensors and having a dedicated sensor on a network like that Such as the raspberry pies obviously just helpful in general When you have to do troubleshooting because being able to pivot into the network like that Or have your browser at the ready because so many things, you know, whether it's a phone system Or really any other devices. These are going to be accessed by ssh Hopefully not but telnet's still out there somewhere and of course web browsers Many things have web interfaces on them But that is easiest access from inside that network now the last thing i'll mention and i have another video And i'm going to link to all these different spots i talked about so you can start with this and then pivot to all these other extras Is using a proxy chain So proxy chaining allows you to pivot into a network and we're going to do this over ssh And then bring your browser as if it's acting inside that network So we're going to do ssh my minus capital d 90 50 that's my proxy chain port and it's the same port i used in my video And then it's just the same kelly at <IP_ADDRESS> then from here This is tmux so i'm able to split the screen Proxy chains and we're going to pull something and what you're doing when you kick off something with proxy change You're wrapping it in that proxy chain. So we'll open up firefox So we open up firefox in that proxy chain And then we're going to go to 192.168 um We'll go back to eight for example Because now we're inside the free nas that's not my local ip address So if we go back over here, we'll even show my computers at 3.18 Now that we're local on my computer and i want to do something like ping 192.168 1.8 I can't do anything like that just doesn't work And if i were to open up a regular browser, it also won't go there proxy chains allows you to be inside that network But then pull it through a proxy chain back over to yours So now i'm at my local browser on my computer But it's chained to that particular raspberry pi which pivots and puts me inside that network And one of the other things that i have inside of here And i've covered this before i've mentioned mi which was something else that the Discovery tool found at 192.168 111 I can get to there And it will load this is actually my sump pump viewer. This is what i'm actually using that camera for nothing too exciting But it lets me know if my sump pump has water in it or not when it's the rainy season And uh, then if we want we can do an h e t p s One of the other discovered ports on that list was my pf sense Gonna add h e t p s colon slash slash There we go advanced Exceptors can continue And now we found my pf sense inside my network now the last thing i'm going to comment on is With zero tier. This is not a noise free Clean way to get into a network now whether or not it gets noticed on a network is a different topic But zero tier one is persistent. We'll figure out ways to get on the network But this is the host host 192 168 1.24 And these are all the connections it has and more specifically and port 9993 That is the initial zero tier connections that it did and these are all the zero tier ip addresses It connects to and talks to to make those connections. So First they're all udp and unless there's specific outbound udp filtering, which is usually not on networks Except for extremely locked down ones and even then It has some other ways that it may try to get around these But for the most part udp escapes pretty much unnoticed on most networks And if you block it you may have problems, but they're For the most part, it's not a noise free is what I really want to bring up So if this goes on a network, if you think you're being anonymous by being on there, well granted, they will know that you're Probably if someone reverses this it takes the time to look at these ip addresses. They may correlate that this is on zero tier So as I said, please make sure you have permission to be on the network And it's not like the cleanest noise free way to get back But it generally works I've had this work on a wide variety of networks with a wide variety of firewalls without any issues at all And I have no ports open on my firewall for this This is all what they refer to as udp hole punching where it just goes out finds those zero-tier servers And then my computer here my laptop went out and found those same zero-tier servers and brokered the connection between there So like I said, I'll leave a link to my zero-tier video where I dive in depth in the network engineering of what makes that work But it's a great tool great product and it makes doing this type of accountants work Just so much easier because like I said, it generally just works all the time out of the box You don't have to go fiddle with anything You just plug the Raspberry Pi in and have a great day or even mail it to someone Provided obviously they know she should be plugging it in mail it to them Have them plug it in because you want to do reconstance on a network But you don't have to have a ton of pre-existing knowledge of their network And especially if you're sending this to a remote client who's well They hired you to be their network engineer because that's not their task This makes it easier for them to plug in now. They don't have to tell you a lot of stuff They just know that hey, I got a switch here and I know I get internet when I plug it in That's all they you know get me internet and this will get online within a few minutes of being plugged in So once again, thanks for watching. I have more in-depth discussion questions comments concerns Outward to the forums is the best place to interact with me and discuss that I'll also leave links to some of the commands I use and of course a list of all the other videos Will be in there as well so you can pivot through You know learning each one of these different things I talked about in more depth.
