I notice the documentation talks about using windows machines to connect to VB but nothing about linux/ubuntu machines.
So, go to a terminal and type:
ssh root@IP ADDRESS OF VB
'root' being the username it will connect with, it will then prompt you for the password you entered when you installed VB. When you are done type 'logout'. So I'm sure lots of folk already know this but I thought it might help someone
If I may, +1 for a wiki for VB!
