Introduction

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.

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:

# vi /etc/xinetd.d/telnet

Change 'disable' from 'yes' to 'no'

2. To allow telnet connections to your machine, add the following to /etc/hosts.allow:

telnetd: ALL

3. Add xinetd to the "DAEMONS" section of your /etc/rc.conf file.

DAEMONS=(syslog-ng network netfs crond ............ xinetd)

4. 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.
