I disagree. There is nothing inherently wrong with FTP. FTP opens a command
channel which exchanges commands with the host and when it is time to
transfer a file it opens another channel on a negotiated ip/port. Many
protocols work this way including the relatively recent (compared to FTP)
SIP protocol. It is a perfectly valid way to handle things. NAT breaks the
end to end nature of the internet and causes the protocols involved to have
to be much more complicated and handle everything within one TCP session.
No, the real problem is that TCP has poor out of band data capabilities (to
the point where using them is considered a flaw in your application
protocol). If TCP had a decent out of band model, you wouldn't need 2 TCP
sessions.
Isn't pointless buck passing fun?
