So the first thing we need to identify is where the SSH port is being made unavailable -- is it in SSH itself, or a firewall?

What port are you expecting SSH to be running on? The default, port 22?

In rescue mode, you can examine the SSH config file by typing this at the prompt, and pressing Enter:

Code:
less /etc/ssh/sshd_config

You can use Space to scroll down a screen, and press 'q' to quit looking at the file and go back to the prompt. We're looking for the 'Port' line to verify what port SSH thinks it's running on.

We should check to see if SSH is enabled. Running:

Code:
update-rc.d ssh enable

Were any firewall changes made by you, or the hosting provider?
