Thanks, I'll try it tonight when I get home. Hopefully putty can do this. Bruce -----Original Message----- From: Jerome R.

Then I might not have to answer the same thing to them! No Since you seam to be confortable with the linux syntax where goes: ssh -L 5902:linux2:5902 [EMAIL PROTECTED] Means: Connect to linux1, singon as user Tunnel traffic from 5902 (on my machine) to linux2:5902 Noe that linux2 is resolved on linux1, so it can be any address linux understands (such as 192.168.x.y) Note that only the mymachine:5902 <--> linux1 is encrypted, the traffic linux1 <--> linux2:5902 is not encrypted, not compressed... you can use this method to get to any machine inside local net which includes linux. This is so usefull that the linux versions of vnc often have a -via (ssh-server) shortcut... vncviewer linux2:2 -via [EMAIL PROTECTED] will do exactly the same thing, and connect you to vnc on Linux2 (works with tightvnc, but for some reason shortcut missing from real vnc) Jerry On Thu, 2004-07-22 at 03:49, Nepple, Bruce wrote: Are you saying that I need to start another ssh session on linux1 "ssh -L 5902:linux2:5902" So, I start putty to linux1 (giving me an ssh session from windows to linux1), then, in the shell I started on linux1 I ssh to linux2 "ssh -L 5902:linux2:5902 linux2", then start my vnc viewer on my windows machine and it will see the vncserver on linux2. Sounds easy enough. Do I need to open anything in the reverse direction? I tried it here at work and it didn't work, but my setup is suspect. on linux2 I ssh to linux1, then back to linux2 "ssh linux2 -L 5902:linux2:5902". If I connect vnc to linux2:5902, it works (since that's where the server is), but if I try linux1:5902 it fails to connect. > -----Original Message----- > From: Jerome R.
