I made a yum update to 4.2 yesterday. The first "major" update I did on CentOS, I'm only using it for a few weeks now, starting with 4.1. Mainly for evaluation for a prospected migration from Suse to CentOS. Basically the update went very well, fast (only 180 MB needed to be installed) and smooth. But there were two small issues where I don't know why they happened: 1. There was a (actually two) spamassassin.rpm of SA 3.1.0 installed, the rpm was built from the tar.gz sources for SA with the specs file provided with it. It produces two files for installation: perl-Mail-SpamAssassin and spamassassin. The update wiped them and installed SA 3.0.4 with this message: Obsoleting: perl-Mail-SpamAssassin.i386 0:3.1.0-1 with spamassassin.i386 0:3.0.4-1.el4 Shouldn't this update get skipped because the version information is higher than the CentOS package? I found several mentions that I can exclude packages from yum updating. How can I do this? I don't want to update only specific packages, I only want to exclude a very few packages. 2. sshd seems to start twice or so since that update. No problems with ssh, though. from boot.log: Oct 24 14:00:16 nx05 sshd: succeeded from warn log: Oct 24 14:00:16 nx05 sshd[1737]: error: Bind to port 22 on 0.0.0.0 failed: Address already in use. Same thing happens when I restart sshd and even when I reload it. There was a new sshd_config installed, I think I read something about removing ssh 1 protocol from it. This can't be the cause. There's only one instance of sshd running apart from the children for actual logins. Why is this happening, how to fix it? There is another question that arises in this context: will a yum update always overwrite with new configuration files, if that file got changed from the originally installed one? I'm used from Suse that new configuration files get saved with another extension if the original file got changed or in some cases it overwrites the file but copies the old file to a backup. I can also expressly exclude some config files from overwriting via sysconfig (if I remember correctly), can I do similar with CentOS?
