Telnet (Español)
From ArchWiki
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.
Instalación
Para usar telnet solo para conectar con otras maquinas, instale el paquete inetutils (si no esta instalado):
# pacman -S inetutils
To configure a telnet server, install xinetd as well:
# pacman -S xinetd
Configuración
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.
