# service --status-all | grep -i "running"
crond (pid  3974) is running...
cupsd (pid  3895) is running...
gpm (pid  3965) is running...
hald (pid 3767) is running...
hidd (pid 3815) is running...
hpiod (pid 3864) is running...
hpssd (pid 3869) is running...

or else

to check if what services are set to run(or on) by default(at system boot)

use the below.
1.check the current run level using
# runlevel
N 5
2.check the list of services set to run at boot time
using
# chkconfig --list > /tmp/service.log

//the output will look like this
yum-updatesd    0:off   1:off   2:on    3:on    4:on    5:on    6:off

3.check the same using awk command according to your current run level
awk  '{if ($5 == "3:on") print $1}' /tmp/service.log

Thanks :)
