This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications..

The Stream Control Transmission Protocol (SCTP) and the Datagram Congestion Control Protocol (DCCP) also use port numbers.
PortCheck is a tiny command line tool for administrators and network admins. You can check if a remote device answers on a certain TCP port. Short overview: Displays permanently whether devices answer on a particular TCP port; Showing answer time in milli seconds with colored output (red/green) Check UDP connection to any port of any IP or website from different places. For example you could check a DNS or game server for availability from many countries. Examples: 8.8.8.8:53. domain://8.8.4.4. cw.live-cs.ru:27997 With netcat you can check whether a port is open like this:. nc my.example.com 80 < /dev/null The return value of nc will be success if the TCP port was opened, and failure (typically the return code 1) if it could not make the TCP connection.
