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?
Thanks,
Kai
