SSH Trick

If you are outside Telin it is possible to connect to an internal Linux server quickly. This is the trick.

Create or edit your local .ssh/config file:

Host proxy
User your_username 
HostName telin.ugent.be

Host *.telin
User your_username
HostName %h
ProxyCommand ssh -q proxy nc -w 3600 %h %p
  • replace your_username with your Telin accountname.

If you add the .telin extension to the ssh host, it will open a connection to the telin.ugent.be server but will connect directly with the netcat connection on to the internal server.

e.g. from home: ssh wanda.telin will open a connection to wanda through the telin.ugent.be server.

This tip will also work for MacOS users! Make sure you have nc available.
