The title is my question. why ftp does not have header? (when use stream mode to send file). Is tcp "shared" header with tcp. how wireshark can distinguish tcp and ftp? asked 25 Oct '16, 09:54  Kyuubi |
One Answer:
Port numbers and communication between the ftp client and server in the command channel (port 21 on the server). See here for an explanation. answered 25 Oct '16, 09:59  grahamb ♦ |
