Submit_host and host key checking

I’m setting up OOD 3.1 on Rocky 8. I’ve got auth configured. I’m working on getting the desktop setup. I’m having to use the submit_host option to ssh into my slurm cluster because it is on CentOS7 and we aren’t ready to update that yet. When I try to submit my desktop job I get this error:

No ECDSA host key is known for and you have requested strict checking.
Host key verification failed.

I’ve tried setting StrictHostKeyChecking no in my users ssh config but that doesn’t help. Any ideas of how to get past this error?


We have a strict_host_checking cluster config option which sets StrictHostKeyChecking=no and UserKnownHostsFile=/dev/null. What happens if you set that to false?

That did the trick. I was looking at the Slurm documentation, not the LinuxHost doc.
