Whelp, my stuff is back online again. I decided to upgrade from Redhat 9 to Fedora Core 4. Instead of migrating everything, I decided to start from scratch. After researching, I figured I would be better off in the long run re-installing. I had a lot of fluff on this box that I needed to do away with, plus I was afraid it would take me longer to fix everything after upgrading as opposed to rebuilding. Now, I’m running the latest versions of Wordpress, Postfix, etc. (yippee!!!). The process was really not as bad as I was expecting, mainly because I had been using rsnapshot to do my backups to an external usb drive. “Piece-o-cake” to get any old config info from my backup. I highly recommend rsnapshot.

The main problem that I had getting everything going again was SELinux. I kept getting weird “permission denied” errors with Postfix as well as SquirrelMail. It was easy to fix once I figured out the culprit. It seems that if there are problems like this caused by SELinux, they are not logged (at least not by default in FC4) in any of the logs in /var/log. I ended up discovering the problem only by strace‘ing Postfix.
