I would suggest that the log from ssh -vvv will probably be more
useful to you, been a while since I looked at SSH in a packet capture
but I suspect that the packets will all be very generic (i.e. there
won't be any explicit notation of WHAT a particular packet is WRT the
SSH protocol).

You should be able to use the timestamps from the log to associate the
packets with each step and between the two you should get a pretty
good idea of what's going on.

This should get you started

Hi Scott,

There's "SSH: the Definitive Guide" on Google books as well.
