Hi There,

I'm new to the forum and i have a question regarding Terminal server please.

I would like to setup terminal server on GNS3 to be able to access my lab remotely. I have Windows 7 setup, what's the best of way of achieving this?
Do i need a linux box setup ? as it's easier to just telnet to linux and start gns3 etc ?

Regards
mcp200

You don't need a terminal server. Dynamips* already provides a terminal service on your PC. All you need to know is the port number that the console of each router is running on.

If you hover the mouse over say router R1 in GNS3, you will see a box of information appear (you can get the same information by typing the command show device R1 in the Console window).

In this list of information you will see something like console is on port pppp

This is the information you need. Once you router is up and running, you can access the console of that router by telnetting to port pppp of your PC from any device that can reach your PC - potentially the whole world if your PC has a public IP address.

Example, if your PC has an IP address of 192.168.1.10, and is running 4 routers in GNS3 with console ports 2001-2004, you can go to another PC and issue the command** telnet 192.168.1.10 2001. You will see the console screen for R1. On the same PC or another PC you could go to another command window and issue the command** telnet 192.168.1.10 2002 and so on till you have your 4 console sessions.

*See this article to see how Dynamips relates to GNS3
**You will have to enable telnet client in Windows Vista/7 before you can issue this command in Windows Vista/7. Why Microsoft? Why?
