It's not really working but I have another problem slowing me down, which is that I can't restart the ssh service.
I can ssh to the server without any trouble. If I do
ps aux | grep -i "ssh" I can see the sshd process but if I do
service sshd restart then I get "sshd unrecognized service". I can restart ssh but I take it that's a client, not a server.
If I Google "sshd unrecognized service" I get to know all about troubleshooting ssh connectivity but that's not my problem.
I tried purging and reinstalling openssh-server, to no effect.
How can I restart the sshd service if that service doesn't exist?
