Re: SSH tunneling for unattended process.

Ah... ok. So SSH is used for auth and encryption, and mainly just as a tunnel (as the first mail mentioned). The traffic that's tunnelled may be any protocol or a TCP socket... and the goal is to just use SSH's ubiquity (say port 22) to make life easier w.r.t firewalls and all that. Is this rig

Thanks Rick. This is the part I don't follow... "You can use SSH directly (with client invoking SSH to launch a service program on the target)". Is it possible to make a simple example? User A at Machine A wants to connect via port 4321 to machine B port 22, and it's just good old SSH connectivi
