How can one disable crond and atd from being brought up on startup ?

I imagine you could comment out the lines

Code:

# Start crond (Dillon's crond):
# If you want cron to actually log activity to /var/log/cron, then change
# -l10 to -l8 to increase the logging level.
if [ -x /usr/sbin/crond ]; then
  /usr/sbin/crond -l10 >>/var/log/cron 2>&1
fi

# Start atd (manages jobs scheduled with 'at'):
if [ -x /usr/sbin/atd ]; then
  /usr/sbin/atd -b 15 -l 1
fi

in /etc/rd.c/rc.M

OR

su -c "chmod -x /usr/sbin/atd"
su -c "chmod -x /usr/sbin/crond"

Are there problems being caused by what cron is running that we might be able to help with?

Cron runs system processes for things like log rotation, locate database updates and kmod so it's worth keeping if it's running properly. I also have mine running general checks (tripwire, rootkit checks, backups, log parsers, downloading ISP mail with fetchmail, etc.).

*uh .. duh* .. of course .. chmod -x on the binary .. been a gentoo user for too long.

gilead: um .. well .. I do those manually every once in a while when I feel necessery ..

I just wanted them disabled.

I'm a resource freak [although I might have no reason to be.. .. but I suppose minimalistic ..*everything* can be a good security thing]

Each to his/her own

Keep an eye on the free space on /var if you're not rotating the logs though
