ssh not accepting valid passwords

[TechBoyJK]

I have a machine running CentOS, and all of a sudden it stopped accepting good passwords via ssh. I can login at the console as root with my password, but if I try and ssh to it, it will give me the login prompt but it won't accept my root password..

Any ideas? I'm googling now but I haven't found anything yet.. I'm really curious as to how to fix this and what went wrong.

The paranoiac in me would run a MD5 summer on the sshd binary that's currently being executed as well as another one from a system with the same version of CentOS/upgrades.

The practician in me would check /etc/ssh/sshd_config to see if PasswordAuthentication is set to no.

Usually root logins via SSH are disabled, if you had enabled it yourself did you happen to upgrade the ssh package or something recently that might have turned that off?
