how to check a server

[simple]

suppose i have simple server program which is listening on a particular port. how do i determine if that server is listening on that port? all this system is running in linux environment. so preferably i need a terminal command...
i can use nmap but i think there would be a much easier way to do it...
thanks in advance!! c ya!!

ping or telnet
