You can also make it run from cron or something, but there's no real point. It's configured by default to only be accessible from your local system, so the security impact is lessened. > xinetd Probably can turn this off, but it's possible you have some service which uses it. This is a "super daemon", and its job is to listen on multiple ports and fire off actual programs to handle the specific requests, so that those multiple programs don't all have to be running all of the time. > cpuspeed This will only load the daemon if it can actually be used by your system. So if cpuspeed ends up running, you probably want it. And if not, having the check at boot won't hurt, but neither will turning it off. > nfs_lock > rpc* This stuff, and portmap, you can most likely turn off if you're not using NFS or NIS. -- Matthew Miller mattdm@xxxxxxxxxx <http://www.mattdm.org/> Boston University Linux ------> <http://linux.bu.edu/>
