I have exactly the same problem mentioned in this thread. I think something
changed and broke the authentication during an update. i found this message by
Googling and just joined the mail list to ask for help. I have done everything
mentioned in the thread, and here's where I'm at: (it worked fine before some
regular update broke it)
Thanks!

Please check your ssh setup:
The following are _examples_ of what you might need to check.
- Make sure "nx" is one of the AllowUsers in sshd_config. (or that
the line is outcommented/not there) - Make sure "nx" is one of the
AllowGroups in sshd_config. (or that the line is outcommented/not there)
- Make sure your sshd allows public key authentication. - Make sure
your sshd is really running on port 22. - Make sure your sshd_config
AuthorizedKeysFile in sshd_config is set to authorized_keys. (this should be
a filename not a pathname+filename) - Make sure you allow ssh on localhost,
this could come from some restriction of: -the tcp wrapper. Then add in
/etc/hosts.allow: ALL:localhost -the iptables. add to it: $
iptables -A INPUT -i lo -j ACCEPT $ iptables -A OUTPUT -o lo -j
ACCEPT[root@tiger ssh]#
