Take the 2-minute tour ×  I have been playing around with
TCPFlow to look at telnet traffic. What I would like to do is
have the output from TCPFlow redirected to a Perl Script that
watches for the phrase "Password:" then prints out the following
password to a terminal window or separate file. How do I
redirect the output from TCPFlow to my Perl Script then
constantly search it to find the "Password" string? Any
suggestions?  share|improve this question add comment  1 Answer
If you open TCPFlow as a subprocess open(my $infh, "<", "TCPFlow
args|"), you can get its output as a filehandle. The manual page
has more.  share|improve this answer You may also want to look

humm...Im not sure how this would work. For tcpflow I can either
write it to the console window or to a file. #tcpflow -c -s is
what prints it out to the console window. So, it would be
open(my $infh, "<", "tcpflow -c -s|")? –  Jesse Miller Sep 5 '10
