Fedora Core 3 seems to have a lot of services running in the default configuration. Which of these are safe to deactivate? I've got FC3 set up on an old PII 400 with very little memory, so I'd like to eliminate whatever's not necessary.
Specifically, it safe to disable the following: readahead sendmail xinetd cpuspeed nfs_lock rpc*
This box wont be using NFS at all, and I can't see any reason why sendmail should be running on anything other than a dedicated mailserver. xinetd similarly seems useless on a desktop computer.
You can safely turn xinetd off, though if I'm not mistaken - xinetd turns itself off if there are no xinetd services it is running.
Sendmail (or postfix) you need for cron - it is by default NOT listening to any external interfaces. It is used by cron to send output of cron jobs to the user, and is used to send logging information to root (which should be redirected to a user)
rpc I think is safe to turn off.
I'll be honest - I'm not completely sure about the others.
