'''Telnet''' ('''Tel'''ecommunication '''Net'''work) is a protocol to access remote computers using Unix or Linux operating systems. The telnet-protocol uses a network connection from the client computer (like a Windows or a Linux PC) to the server computer. In most cases here the server is the Dreambox receiver.

Telnet (Telecommunication Network) is a protocol to access remote computers using Unix or Linux operating systems. The telnet-protocol uses a network connection from the client computer (like a Windows or a Linux PC) to the server computer. In most cases here the server is the Dreambox receiver. The goal of a telnet session is to operate the server at the shell.

Because the transmission is in plain text, passwords can be captured by simple methods. You should use encrypted protocols like SSH.

Clientsoftware

A Telnet client is installed on nearly every computer. In Windows, you do it generally via the command line. In Windows Vista, Windows 7 and Windows 8, the telnet client must be enabled first. In Linux, simply use the telnet command from the shell. You can also use other programs to connect to a Telnet server.

Attention: Some clients need a password that must first be set via telnet (e.g. SSH will not work without a password).

Commands in the Shell

Read the overview about BusyBox.

"Telnet" is usually running in command-lines.

The equivalent in Windows is the "DOS window" or the "Command line".

In Linux, it is e.g. Shell, Bash, Terminal and so on.

More information about Telnet is available on Wikipedia.
