Telnet is the traditional protocol for making remote console connections over TCP. Telnet is not secure and is mainly used to connect to legacy equipment nowadays. For a secure alternative see SSH.

Follow these instructions to configure an Arch Linux machine as a telnet server.

Installation

To use telnet only to connect to other machines, install inetutils (if not already installed):

# pacman -S inetutils

To configure a telnet server, install xinetd as well:

# pacman -S xinetd

Configuration

1. To allow telnet connections in xinetd, edit /etc/xinetd.d/telnet and change 'disable = yes' to 'disable = no'

2. Add xinetd to the DAEMONS array of your rc.conf:

DAEMONS=(... xinetd)

3. Reboot or restart xinetd:

# /etc/rc.d/xinetd restart

Testing the setup

Try opening a telnet connection to your server:

$ telnet localhost

Note that you can not login as root.
