SSH tunnel to a certain node

• Submit a slurm job, or start an interactive job on a node.

sinteractive

or for a Nvidia A100 GPU:

sinteractive -p gpu --gres=gpu:1 --constraint='nvidia&A100'

• Check on which node this job has landed

squeue -u $USER -l

• Add this to your machines ssh config in ~/.ssh/config

Host node* gpu*
    Hostname       %h.internal.anunna.wur.nl
    ProxyJump      login.anunna.wur.nl
    User           your_user_id

Host *.anunna.wur.nl
    User           your_user_id 

• You can now use your local terminal connecting to e.g. node201 directly, by:

ssh node201

• In VSCode :

in the VSCode GUI -> Open a remote Window -> Connect to Host...,type in the nodename. After a few seconds, VSCode is connected to the node.

Please be aware that once the slurm job finishes, the connection will be lost and your running processes will be killed. Besides that, you are limited to the amount of RAM that you requested.
