Thanks to Mark's observation ... I found a fairly trivial solution to
what's been a rather difficult problem. :)
On the demo Linux echoServer, I ran this command as root:
# ssh -N -g -L 66.135.32.141:443:127.0.0.1:1328 [EMAIL PROTECTED]
I'm using version version 4.3p2 of OpenSSH.
What that command does is cause ssh to open a tunnel from the
port 443 on the external IP address (66.135.32.141), and securely
tunnel it to port 1328 on the loopback interface, where the echoServer
is listening. On this PC, I also have an account "echoserver" which
runs the service, hence the "[EMAIL PROTECTED]" part.
The neat part about this solution is that the echoServer is now
effectively listening for connections on two ports: TCP 1328 and 443.
Previously, two instances were running, and users logged into one
were not logged into the other, so they couldn't connect with each
other. The SSH "trick" is a pretty easy workaround for this. I see no
reason why it wouldn't scale to an arbitrary number of ports...
cheers,
Scott
