I am trying to set up ssh-server on my Ubuntu 12.04 VM (running in VirtualBox on Mac OS X 10.7).
I have a domain name, call it foo.com, and I'd like to make ssh available via ssh to linux.foo.com. (I want this to be accessible from outside the local network.)
How can I do this? Do I need a static IP address or is there a way to dynamically forward traffic?
