Make use of security tools out there to test your server's weaknesses. Nmap
is an excellent port scanning tool to test to see what ports you have open. On
a remote machine, type the command:
# nmap -sTU
Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2006-08-10 13:51 EST
Interesting ports on eric (172.16.0.1):
