In the context of the "services turned on by default by redhat or whatever distro" what I meant was, how do I tell if redhat has set up some at jobs. Answer is, execute "atq" as root. > > > How can I tell whether I'm actually using crond or > > anacron? Or both? > > ps auxww | grep cron > chkconfig --list | grep :on | grep cron Again, in this context the result of the above just tells me they're running, not whether I am actually using them. Is it ever a good idea to run both? Red Hat apparently set up some anacron jobs, but I can't find any cron jobs, should I turn cron off if I don't intend to use it myself? > > > How can I tell if something local is using sendmail > > for logging? > > You mean syslog? See /var/log. Well, I mean how do I know if some background job is using sendmail for some legitimate purpose so I don't want to turn it off. Looking in /var/log did not clue me in. I'm just turning it off, let's see what happens. Also... When I execute "chkconfig sendmail off" and then "chkconfig --list|grep sendmail" I get: sendmail 0:off 1:off 2:on 3:off 4:off 5:off 6:off Do I want to turn it off on run level 2? What is level 2? I tried man chkconfig, man runlevel, and man rc.d & got no clue. Where should I be looking? cheers, TB
