Well, his problems are getting things to work on top of TCP, so he
It shouldn't be needed (TCP has automatic retransmissions and so on),
but I have
seen that behavior with ssh with a "lossy" network. If you were fast,
you could start
a session and get to the file list, but as soon as it started losing
packets, it froze.
Tweaking the TCP options with more aggressive resending should help.
