How i can to capture FTP-data packets via tcpdump?

When i try to capture FTP packets tcpdump only captures packets which have not text from transmitted .txt file - they are only contains information about my command, directory etc.

I've used this command:

tcpdump src x.x.x.x and dst x.x.x.x and port ftp
Solution

  • try 

    tcpdump 'src x.x.x.x and dst x.x.x.x and (port ftp or ftp-data)'

    (per http://www.tcpdump.org/tcpdump_man.html )
