Bamboo: Password required to ssh to a compute node on bamboo

1

Hi HPC,

I am trying to use the new cluster bamboo. But im having an issue with password requirement when sshing directly into a compute node (specifically an issue in vs code)

Without any issues i can do:

ssh algren@login1.bamboo.hpc.unige.ch
or
ssh bm

and afterwards

salloc -n1 --partition=shared-gpu, --time=7:00:00 --mem=15G --gres=gpu:1

To get (as an example ) gpu001.

But if i want to ssh directly into gpu001 with ssh diff~bmgp, it asks me for a password.

Is it suppose to be asking for password when it already has my public key? How do i avoid it asking?

Host diff~*
  RemoteCommand apptainer shell -B /srv,/home --nv /home/users/a/algren/singularity_images/diffusion-torch-2.2.0.sif

Host bm
  HostName login1.bamboo.hpc.unige.ch
  User algren
  RequestTTY yes

Host bmgpu diff~bmgpu
  HostName gpu001
  User algren
  ProxyJump bm

Hi @Malte.Algren

Could you try this:

Be carefull the ssh-copy-id does not work you will need to use the -f option.

And then it should work.

Tested and approuved:

[alberta@localhost .ssh]$ ssh -F config_bamboo cpu002 
alberta@cpu002's password: 
Killed by signal 2.

[alberta@localhost .ssh]$ ssh-copy-id login1.bamboo.hpc.unige.ch -f
/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/alberta/.ssh/id_rsa.pub"

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'login1.bamboo.hpc.unige.ch'"
and check to make sure that only the key(s) you wanted were added.

[alberta@localhost .ssh]$ ssh -F config_bamboo cpu002
