SSH

To access interactive sessions via ssh, users can connect to the machine shell.techfak.de with their TechFak username. This is intended as a pass-through machine to connect to other computers within the TechFak network. A one-time setup is required to log in.

One-time setup

An SSH key pair is required to access shell.techfak.de. This key can be uploaded either via our web interface https://techfak.net/remote/setup.md or on one of our Netboot computers using the command line program tf-ssh-auth-keys. In both cases the user needs the TechFak-Mail-Password to authenticate.

Generate a new key pair: 

ssh-keygen -t ed25519
Upload the key within the university (or in the VPN) at https://techfak.net/remote/setup.

We recommend using PuTTY for Windows. Instructions can be found in the following video
