Hi,
can anyone very shortly clarify what runs from cron?
- certwatch (update ssl-certs?)
- tmpwatch?
- yum update
- makewhatis?
Check /etc/crontab and /etc/cron.{d,hourly,daily,weekly,monthly}
For more details for most of these, use man - man certwatch, etc.
Is the esmith going to update itsself automatically (yum)?? I would not like that at all for stability reasons of course.
Yes, it will, by default. There is a server-manager toggle and matching config db value if you wish to disable this. It is much better for us to err on the side of caution by applying updates automatically. Those who want to disable automatic updates can, but this default helps to protect unmaintained systems.
Where is clam antivirus updating itsself?? I see in /etc/clam.d clamav, but that has no code in it.
freshclam is running under supervise. The clamd binaries will be updated automagically via yum.
What do tmpwatch and makewhatis do?
See above - the man pages probably tell you more than you want to know.
