I use SSH "Controls" by default on my desktop PC. This makes setting up new connections more efficient and quick. It also means that you think you are on a "New" SSH connection when in fact you are on an existing connection. I may now have to ask my hosting company to reboot the box as I now think I've stopped the SSH server and now can't reach the damn thing...

Serves me right for having a good day yesterday in expanding the size of a running KVM session's filesystem!
