VPN (Virtual private network)

Connecting to a VPN allows you to access the network as if you were physically at DTU.
or security reasons, this might be needed for some services.

Tutorial form DTU Compute Wiki:

ssh userid@login1.gbar.dtu.dk

ssh userid@login1.hpc.dtu.dk

ssh userid@login2.gbar.dtu.dk

ssh userid@login2.hpc.dtu.dk

Using the terminal:

ssh -X userid@login1.gbar.dtu.dk
