Hey there, thanks for answering. Could you be more specific pls? I'm not sure how this could help. All users will have regular logins (pseudo-ttys) and can send escape sequences to ssh. > > >I'm trying to build an idiot-proof menu for non tech savvy users to allow > >them > >create a couple of tunnels to local services (on different ports), on demand. > >The script needs to run a bunch of other stuff after adding the tunnels, so I > >can't just tell them to pass '-L etc.' to the client.. Let me rephrase this to avoid further misunderstandings. I've got this scenario (anything prior to '$' is the hostname): userbox$ ssh u...@foo.bar foo.bar$ printf "%s@%s\n" "`whoami`" "`hostname`" u...@foo.bar Let's say the user wants to add a tunnel to her current ssh connection for accessing httpd running on server foo.bar. The httpd listens on localhost only. I want to automate this process: foo.bar$ ~C ssh> -L 2000:localhost:80 Forwarding port. -- Manolis Tzanidakis http://mtzanidakis.com/ mtzanidakis[at]gmail[dot]com
