I am the admin of a private server. I'm pretty new to admining. SSH was working fine, then I upgraded to 14.04. Something went wrong with the upgrade so I downgraded to 13.04. Now SSH doesn't work, that is, when a remote tries to connect, the server doesn't respond. The network card (wireless) works fine. I can ping without a problem. When I ps -ef | grep sshd I see the process running. But when I sudo /etc/init.d/ssh status I get no response. Doing a sh -x /etc/init.d/ssh status I can see that it looks like it is going to /sbin/initctl version, return 0, exit 1. When I do a /sbin/initctl version, it spits out a version just fine.

Anyone know what could be happening? What should I do next?
