services
 

I'm running CentOS 4. This box is going to be used for Snort. I have the following services still open on the box but would like to know which ones I can close.

microcode_ctl
cpuspeed
arptables_jf
iptables
network (I know to leave open)
syslog (same here)
irqbalance
portmap
mdmonitor
lm_sensors
acpid
sshd (leave open)
rawdevices
crond (leave open)
anacron
atd
messagebus
haldaemon
local

Thanks!

Only portmap looks like any sort of security risk to me.
