Excess Daemons and Cleaning Up

One thing I don't like about a full install of Redhat is that it will install lots of useless programs and daemons. Here's a small checklist of some of the things I turn off or remove from a system I set up.

Clean up crontab stuff (this is how I like my crontab file to look like - nothing more)

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/
# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

Remove some hourly and daily scripts (these annoy me)

rm -f /etc/cron.hourly/inn-cron-nntpsend
rm -f /etc/cron.hourly/inn-cron-rnews
rm -f /etc/cron.hourly/diskcheck
rm -f /etc/cron.daily/00-logwatch
rm -f /etc/cron.daily/00webalizer
rm -f /etc/cron.daily/inn-cron-expire
rm -f /etc/cron.daily/tetex.cron
rm -f /etc/cron.daily/tripwire-check
rm -f /etc/cron.daily/slrnpull-expire
rm -f /var/spool/cron/mailman

Clean up runlevels (not needed - look up chkconfig `man chkconfig` - it is very useful)

chkconfig --level 123456 sendmail off
chkconfig --level 123456 isdn off
chkconfig --level 123456 linuxconf off
chkconfig --level 123456 iscsi off
chkconfig --level 123456 atd off
chkconfig --level 123456 kudzu off
chkconfig --level 123456 xinetd off
chkconfig --level 123456 rhnsd off
chkconfig --level 123456 portmap off
chkconfig --level 123456 nfslock off
