It should be "nmap", which is network port scanner.

nmap allows all kinds of incomplete TCP connects,  etc etc
btw, port-scanning is a pretty security-sensitive issue, so be sure you are not unduly doing something which your sysadmin might not want. Exceptions to this case are when you urself are the sysadmin ;)
