Connecting from a Linux Client

SSH without X11 Forwarding

This is the standard method. Official X11 support is provided through NoMachine. For normal SSH sessions, use your SSH client as follows:

Bash
ssh $username@login001.merlin7.psi.ch
ssh $username@login002.merlin7.psi.ch

SSH with X11 Forwarding

Official X11 Forwarding support is through NoMachine. Please follow the document {Job Submission -> Interactive Jobs} and {Accessing Merlin -> NoMachine} for more details. However, we provide a small recipe for enabling X11 Forwarding in Linux.

  • For enabling client X11 forwarding, add the following to the start of ~/.ssh/config to implicitly add -X to all ssh connections:
Bash
ForwardAgent yes
ForwardX11Trusted yes
  • Alternatively, you can add the option -Y to the ssh command. In example:
Bash
ssh -X $username@login001.merlin7.psi.ch
ssh -X $username@login002.merlin7.psi.ch
  • For testing that X11 forwarding works, just run sview. A X11 based slurm view of the cluster should popup in your client session:
Bash
sview
