The purpose is to capture all the Request/Response send through SoapUI. For example, using dumpcap and windump, executing this command:\r\n\r\ndumpcap -w resp_20150908.pcap -f \"tcp port 80\" \r\n\r\nwill save the request, but the response is avoided. In the other hand, if the -f parameter is not set, the response is captured as well. And yes, the response goes through port 80. Capturing network data using Wireshark at the same time, the response is captured properly.\r\n\r\nI've tested the dumpcap tool with two Windows 10 machines, and two Windows 7. The response appears in both win7, but not in any win10 machine.\r\n\r\nSeeing the same problem with dumpcap and windump lead me to think that the problem came from libpcap."},"comment":{"url":"https://api.github.com/repos/the-tcpdump-group/libpcap/issues/comments/138665585","html_url":"https://github.com/the-tcpdump-group/libpcap/issues/455#issuecomment-138665585","issue_url":"https://api.github.com/repos/the-tcpdump-group/libpcap/issues/455","id":138665585,"user":{"login":"guyharris","id":3599441,"avatar_url":"https://avatars.githubusercontent.com/u/3599441?v=3","gravatar_id":"","url":"https://api.github.com/users/guyharris","html_url":"https://github.com/guyharris","followers_url":"https://api.github.com/users/guyharris/followers","following_url":"https://api.github.com/users/guyharris/following{/other_user}","gists_url":"https://api.github.com/users/guyharris/gists{/gist_id}","starred_url":"https://api.github.com/users/guyharris/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/guyharris/subscriptions","organizations_url":"https://api.github.com/users/guyharris/orgs","repos_url":"https://api.github.com/users/guyharris/repos","events_url":"https://api.github.com/users/guyharris/events{/privacy}","received_events_url":"https://api.github.com/users/guyharris/received_events","type":"User","site_admin":false},"created_at":"2015-09-08T18:44:42Z","updated_at":"2015-09-08T18:44:42Z","body":"What version of WinPcap or Npcap are you using?"}}
