How to listen on a port for commands

[jlstitt]

Hello,

I am hoping to write a program that will listen on a port and react similar to when you telnet into a POP3 port ... ie, have a "prompt" and accept commands (on a UNIX box).

My questions are:

1. How do I create a program that acts as a daemon (stays in memory) ... and which shows the daemon name and not the whole command line in the process list

2. How do I "listen" on the port and accept client connections. Also, how do I handle more than one connection at a time?

Thanks very much for the help.
