  • Press enter once
  • If you are asked Overwrite (y/n), enter n
  • Otherwise, just press enter at every prompt
• Enter $u = "alice", replacing alice with your own GPU Server username
• Enter ssh $u@gpu-server.dhlab.intra.uni-freiburg.de "mkdir ~/.ssh"
• Enter type $env:USERPROFILE\.ssh\id_ed25519.pub | ssh $u@gpu-server.dhlab.intra.uni-freiburg.de "mkdir -p ~/.ssh; cat >> ~/.ssh/authorized_keys"
  • If you are asked whether you are sure you want to continue, enter yes
  • Enter your GPU Sever password
• Optional: Enter ssh $u@gpu-server.dhlab.intra.uni-freiburg.de "hostname" to test whether everything worked
  • You should directly get gpu-dhlab without being asked for a password
