This is forwarding port 5900 on your remote system to port 5907 on your local system. Someone on the remote system could log into your local VNC server running on 5907, but you can't go the other way... > Through trial and error I tried the following > > putty -ssh -l harryk -P 24 -L 5900:remote:5907 remote > > which doesn't give me any errors, but also doesn't allow me to login.

The scenario you describe where I connect my local port 5900 with the remote port 5907 I thought (past tense :) ) would have been correct. Then when I run vncviewer, I would connect to the localmachine on display :0 (port 5900). I think the problem is that it might be trying to listen correctly, but from the leaf box, instead of the internal machine. However, I will try to swap the ports and will post my results. joey -- Charles Steinkuehler [EMAIL PROTECTED] ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ leaf-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-devel
