I am not sure if this is the right forum - but would appreciate help. I did a yum update on November 1st using a development Fedora 8. After this I rebooted the machine (a leased server) and could not ssh as root. I could access the site via webmin and by "re-enabling" the users I could then start ssh and other services. I then rebooted and found that I could not login with either ssh or with webmin. I currently have the server mounted through a gentoo CD. However, I am stumped. I think the issue may be with pamd - but everything looks fine. I also suspect xinetd. Looking at the messages logs I see a EXT-fs check was forced on the disk on a reboot. I have also run e2fsck from the cdrom on the unmounted disk and it is clean. Below I attach a list of what yum did. and also a tail of the secure log as well as messages log.
I would be grateful for your advice.

That indicates that the disk was corrupted. You're boned.
There's no real way to determine what ended up being broken, without doing a more complete, detailed analysis. There could be any number of hundreds of differents reasons why your system is screwed up.
The easiest thing to do is to just reinstall.

Hi Stephen Pusey!
The words "allow root access" seem to be ringing in my mind.
Pgp comes to mind.
Sam is probably right but look for a change in ownership, or basic configuration of SSH or its dependencies.
Good Hunting!
