Slice key issue

[Michael Zink]

Hi,

it looks like there’s an issue with my slice key since I cannot login to the VM I created.
This is on the FABRIC node at MGHPCC. My UUID is

40d793ef-4450-4059-8923-f048fb7a123a

Here’s the error message I get:
fabric@winter:fabric_config-80%$ ssh -i /home/fabric/work/fabric_config/slice_key -F /home/fabric/work/fabric_config/ssh_config rocky@2001:48e8:6401:3:f816:3eff:fed9:fa68

Thanks,

Hi Mike,

This could possibly be because your Bastion Key has expired. Could you please try running the  notebook jupyter-examples-rel1.8.1/configure_and_validate/configure_and_validate.ipynb again?

This should renew the keys. If error persists, could you please share if you see any errors in /tmp/fablib/fablib.log

Thanks,

Komal

Thanks, Komal.

I created a new bastion key but totally forgot to run the notebook.

I can run the notebook without any issue but I still cannot ssh into the VM.

Error message is pretty much still the same.

Hi Mike,

Could you please check following files and ensure they point to the new key and have the right bastion username?

/home/fabric/work/fabric_config/fabric_rc

/home/fabric/work/fabric_config/ssh_config

Also, just verified that the VM in question seems to have been deleted.

Thanks,

Komal
