[plug] SSH Tunnel

[Michael L. Benjamin]

Hi Phil,
 
Server2 (pop3) doesn't offer SSH, therefore the last hop on the link has
to be un-encrypted.
 
I figure I could do something with netcat... I'll keep playing with
it...
 
Mike.

Is there a reason you don't want to use putty from the XP box straight
to server2 (pop3)?
 
What you can do is set up a tunnel in putt as follows: Local Port: 9999
Remote Port: mail.somewhere.net:110
 
This should work AFAIK.  It will encrypt the link between you and
server1 and make it look like the traffic to mail.somewhere.net is
originating from server1.  Is this what yuo are looking for?
 
hth,
Phil.

I'm attempting to setup an SSH tunnel without too much success.
 
What I want to be able to do is SSH tunnel from an XP machine to a Linux
box, then from there access a remote Linux mail machine running POP3.
 
Then I'd setup a PuTTY session with the local port forwarding so that I
can connect a POP3 mail client to localhost on a port that would connect
via the SSH tunnel
to the first remote server.
 
So, say connect to localhost:9999 which connects to server1:9998 which
in turn connects to mail.somewhere.net:110 
 
Can anyone suggest a good way of doing this? Is it feasible, and do I
need to use a combination of SSH and netcat?
 
The final link is not encrypted sadly, but I want everything else to be
SSH2  from there on back to my desktop machine.
