Introduction

Telnet 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 (Link only in German).

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

Clientsoftware

A Telnet client is installed on nearly every computer.
In Windows, you do it generally via the command line.
In Windows Vista and Windows 7, the telnet client may have to be activated (see link).
In Linux, simply use the telnet command from the shell.
You can also use other programs to connect to a Telnet server.

• BitVise
• Kitty
• OpenSSH

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

Start Session

The call is made in each case from the console with

telnet $IP_Address

where $IP_Address is of course the IP address of your Dreambox (e.g. 192.168.0.1).

The presets on the boxes are:

on DM500, DM5600, DM5620, Triax 272, DM7000

• username: root
• password: dreambox

on DM 500+, DM 500 HD (v2), DM 520, DM 600 PVR, DM 520, DM 525, DM 800 HD PVR, DM 800 HD se (v2), DM 820 HD, DM 900, DM 920, DM 7020, DM 7025(+), DM 8000 HD PVR, DM 7020 HD (v2), DM 7080 HD

• username: root
• no password

After logging in, you are at the Linux shell.

Commands in the Shell

Read the overview about Busybox and its commands.

"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.
