in this case, I was thinking I was going to run gq - a gtk+ driven ldap
browser. Seeing as how it contains the hashed passwords for every user
account, it seemed that if I was going to do that, it should at least be
encrypted. Hence my question. My initial assumption if I launched this
program from the remote system using the ssh connection, that it would
be encrypted but I am dumb on these matters and didn't trust my
assumption...hence my question.

I certainly recognize that if I ssh from A to B and then telnet from B
to C - that the segment of traffic between B & C would not be encrypted
and I pretty much assume that if I am sitting in front of machine A
which per the above, has opened an ssh session to Machine B which has
opened a telnet session to machine C, that the telnet session is
encrypted between A and B. My primary concern was that the network
between A and B is insecure (i.e. internet). Again though, my question
never considered a machine C at all.
