First:
/sbin/chkconfig --list

Second:
yum install nmap	# One time
nmap localhost		# Any time you want to see what's running

Be careful with nmap.  Some people get annoyed when you portscan their
machines, especially if the machine is a high-security piece of
infrastructure like a DNS server run by a large organization.

Third:

This starts with a portscan, and then connects to interrogates, and
attacks every service on your machine to see what's there and what's
vulnerable.  It's a powerful tool -- take the warning about nmap,
amplify it 100x.  But, it's a fantastically wonderful tool for auditing
your own machines, whatever OS they happen to be running.


I hope this helps,
