[olug] VNC/SSH tunnel

[David Walker]

~/.ssh/config (settings for your profile only) and/or 
/etc/ssh/ssh_config (settings for entire machine) are settings for the 
ssh *client*, not the *server*.  (/etc/ssh/sshd_config is for the server)

Once you change the setting in one of those files, the ssh command that 
vnc (with via) uses will use the alternate port.  Use the lines below to 
specify that you want to use port 2299 for all outgoing ssh connections 
except for connections to the specified IP, in which case you want to 
use port 2211.

Host *
        Port 2299

Host 192.168.1.106
        Port 2211
