Re:login session transcript

It will be hard to tap the wire and dump the traffic on a second
machine if you will be giving them an SSH account since the entire
sessions would be encrypted. However, if you'd go for a telnet access,
you can connect both machines to a hub, configure the second machine
to sniff the traffic passively and keep the dumps for review. If you
are still paranoid of the possibility of attacking the second machine,
keep the wires that send traffic from vendor machine to the sniffing
machine and cut the wires that send the traffic the other way around.

for a host-based solution, I can't think of any in the moment, except
if you are thinking of back-dooring your system!
