Getting started with tcpserver

Some people think that using tcpserver is complicated. It really isn't. In the following example you'll run a fake telnetd that simply prints a string to the network and then closes the connection.

Fake telnetd

In a shell window, run this command line:

  tcpserver -v -RHl0 127.0.0.1 2023 sh -c "echo 'Go away!'"

In another shell window, connect to the fake telnetd:

  telnet 127.0.0.1 2023

Explanation of tcpserver command line options

-v

tcpserver writes status messages to stdout. In a real world setup multilog will pick up the logging information.

  -RHl0

This prevents various DNS lookups. See the man page for details.

  127.0.0.1 2023

Listen on 127.0.0.1, port 2023.

  sh -c "echo 'Go away!'"

This is the program that tcpserver runs upon each connection.

Real world example

A complete setup of a daytime server.
