I tried to ssh to localhost on my UBUNTU PC but the connection was refused:
UBUNTU > ssh localhost
ssh: connect to host localhost port 22: Connection refused
UBUNTU >
This was because ssh had not been set up on my machine. I set it up like this:
UBUNTU > sudo apt-get install openssh-server openssh-client
