[NMAP](http://www.insecure.org/nmap?ref=kudithipudi.org) is an open source network scanning utility. It has tons of options and is a very powerful tool that every administrator needs to know about. Recently, we were checking if UDP port 88 was open on a certain server. NMAP to the resuce :)..

**nmap -sU -p 88 DESTINATION\_SERVER\_IP** did the trick. The “-sU” option forces nmap to only scan UDP ports and “-p” forces nmap to only scan the specified port.
