If you use SSH....


ssh -L 5555:localhost:5900 whoever@XXX.XXX.XXX.XXX

and then VNC to you can tunnel your VNC over ssh @ 256
bit encryption. That's what I do for RDP(port 3389) and VNC. I don't
like risking losing my logins and even with RDP 48bit encryption is
better than plain text but it's still kinda smelly.

If you REALLY want to get crazy throw a -C in there to turn on
compression and you should see better performance on a tight bandwidth

FYI: Change Halt at work today.... bored, heh ;-)
