What is Telnet? Telnet is a program that runs on your computer and connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid username and password. Telnet is a common way to remotely control Web servers and is incorporated in many Routers. How do I Telnet to my router Either use the command prompt in your OS or preferably use a program like PuTTY (available in downloads). either from command prompt enter: Telnet example: telnet 192.168.1.1 you will then logon to the router. some versions of firmware will ask for a username and password. these are the same as for entering the web based screen on your router. default would be username: root password: admin once you are logged on you can access the internals of the router. a good knownledge of the routers commands is really needed to be understood before you do anything like this.
