Top Forums UNIX for Dummies Questions & Answers Find what process on port number Post 302267295 by zaxxon on Friday 12th of December 2008 05:30:08 AM

Code:
lsof -p <pidofyourprocess> | grep -E "TCP|UDP"

It should show something like (I took apache2 in my example):
Code:
apache2 30941 root    4u  IPv6 264107             TCP *:www (LISTEN)
apache2 30941 root    6u  IPv6 264112             TCP *:webcache (LISTEN)

You can check this service names (www and webcache) in your /etc/services to get the port number.

HUNTD(6)							 BSD Games Manual							  HUNTD(6)

NAME
huntd -- hunt daemon, back-end for hunt game SYNOPSIS
huntd [-s] [-p port] DESCRIPTION
huntd controls the multi-player hunt(6) game. When it starts up, it tries to notify all members of the hunt-players mailing list (see sendmail(8)) by faking a talk(1) request from user ``Hunt Game''. The -s option is for running huntd forever (server mode). This is similar to running it under the control of inetd(8) (see below), but it consumes a process table entry when no one is playing. The -p option changes the UDP port number used to rendezvous with the player process and thus allows for private games of hunt. This option turns off the notification of players on the hunt-players mailing list. INETD To run huntd from inetd(8), you'll need to put the hunt service in /etc/services: hunt 26740/udp # multi-player/multi-host mazewars and add the following line to /etc/inetd.conf: hunt dgram udp wait nobody /usr/games/huntd huntd Do not use any of the command line options; if you want inetd(8) to start up huntd on a private port, change the port listed for hunt in /etc/services. NETWORK RENDEZVOUS
When hunt(6) starts up, it broadcasts on the local area net (using the broadcast address for each interface) to find a hunt game in progress. If a huntd hears the request, it sends back the port number for the hunt process to connect to. Otherwise, the hunt process starts up a huntd on the local machine and tries to rendezvous with it.
