Bug Description
I upgraded from 11.04 to 11.10 and upon completion found that I could no longer ssh into other computers that I routinely do so. There are several things I've checked:
1. Kerberos authentication is working fine, that's not the problem.
2. I tried restarting and reinstalling ssh, but neither helped.
3. I tried copying over all ssh related files from my laptop (with a properly function ssh in 11.04) and replace what is on my 11.10 malfunctioning OS, but that did not help.
4. I tried deleting the .ssh/known_hosts file. On my next attempt, I received the normal message about connecting somewhere for the first time, but was still refused a connection.
5.

Maybe the problem is in that readout, but I'm not familiar enough with this output to know.
My laptop which still has Ubuntu 11.04 still can successfully log into the computers I need to, so the problem is definitely related to the upgrade of my desktop to 11.10.

Hi Jason, thanks for taking the time to file a bug report, and I'm sorry you're having trouble.
The sshd -ddd needs to be run as root to be able to listen on port 22.
Also, an output from your laptop of
ssh -vv your.desktop. address
Will help to debug this issue.
