Telnet server in 4MLinux

4MLinux has the following set of its main servers: FTP, HTTP, SSH (with SFTP), and Telnet. This post aims to describe shortly how to use the Telnet server. 4MLinux includes a Busybox applet as its Telnet server daemon.

Note:
Telnet connections are not very secure because unencrypted data is transferred. Therefore telnet protocol should be applied inside trusted local networks only. Servers connected to the Internet should use Secure Shell (SSH) instead.

1) Open your terminal and execute the 'telnetd' command:



2) Let's start the server ('telnetd start') and check if it really runs ('telnetd test'). After you execute these two commands, you will see the following login screen:
 


3) By default, none of 4MLinux servers is started automatically during the boot, but you can change this by setting 'TELNET' to 'yes' in the /etc/server/autostart.conf file:



4) If you are a fun of TUI (like I am :-), then you can use the 'telnet' command as your Telnet client (just try it yourself in your terminal). If you prefer GUIPuTTY will be the best choice for you:




Note:
4MLinux uses inetd to manage its main servers.
