Telnet
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.
To configure a telnet server, install xinetd as well.
Configuration
To allow telnet connections in xinetd, edit /etc/xinetd.d/telnet
, change disable = yes
to disable = no
and restart xinetd service.
Enable systemd xinetd service if you wish to start it at boot time.
Testing the setup
Try opening a telnet connection to your server:
$ telnet localhost
Note that you can not login as root.
