Enable Telnet

Question

What ist Telnet and how can I enable it?

Solution

Telnet is commonly used network protocol that openly exchanges commands from a client to a server. For control purposes, it is recommended to use the protected SSH communication, but for simple tests of port accessibility it is an effective solution.
For the debugging steps we recommend, only the Telnet client application is needed. If it is not activated, you may receive an error like "'telnet' is not recognized as an internal or external command, operable program or batch file.".

For Linux: Telnet client should be usable by default. If you get an error message like "bash: telnet: command not found", you can install it with the following commands in your shell:
- "apt-get update"
- "apt-get install telnet"
This is not to be confused with telnet server! For use with IPG products you do not need to install telnet server functionality.

For Windows: Since Windows Vista, Telnet client is installed but deactivated by default.

To activate on Windows 7:
- Open "Control Panel > Programs" and select "Turn Windows features on or off" under the category "Programs and Features".
- In the Windows Features list, select "Telnet Client" to activate it, then apply the change.
- Try typing "telnet /?" in the command prompt (cmd.exe) to test and see the command line options
