Remote access over an SSH tunnel

My GNS3 server is physically located in my home lab. As someone who likes to test new ideas while on the road, I can start a SSH tunnel to access the lab from any remote location. In fact, I am writing this post and working in the lab from a hotel room.

GNS3 over an SSH tunnel:

ssh -L 3080:192.168.86.40:3080 murray-home.ddns.net

Open a web browser and connect to:

http://localhost:3080/

I prefer to use a terminal session as the console. The existing SSH tunnel can dual purpose as a way to access the console:

[email protected]:~$ telnet 192.168.86.40 5039
Trying 192.168.86.40...
Connected to 192.168.86.40.
Escape character is '^]'.
