No, you don’t need to run “add/remove SSH keys” notebook. By default, when you create a slice, keys specified in your fabric_rc are already added to the VMs.

@Sanjana – your config looks correct. Could you please try creating a slice and try SSH? If the SSH still fails, could you please share your public key: /home/fabric/work/fabric_config/slice_key.pub

I can verify the correct key is being passed to the VM or not from backend.

Thanks,

Komal

@Vaiden – Issue has been resolved. You may have to do the following to resolve in your slice:

• Remove MAX VM and FabNetv4 Network Service connected to it
• Submit
• Add Max VM and FabNetv4 Network Service
• Submit

Thanks,

Komal

@Sanjana,

Could you please share the output of following commands:?

cat ~/work/fabric_config/fabric_rc

cat ~/work/fabric_config/ssh_config

ls -ltr ~/work/fabric_config

Thanks,

Komal

@Sanjana – Could you please remove this file if it exists ~/work/fabric_config/ssh_config and run the validate_and_config.ipynb  notebook again?

Please try SSH to VMs via command line and share the error you see if it still fails.

Thanks,

Komal

@Sanjana – glad to hear that you were able to create a slice successfully, are you still facing errors when you SSH to the VMs?

Thanks,

Komal

[Komal Thareja]

@Sanjana,

Could you please follow the notebook: jupyter-exanples-1.6.*/configure_and_validate.ipynb to ensure your configuration is correct? Please try creating a slice after that and let us know if you still run into errors.

 

Thanks,

Komal

Good morning Nagmmat,

This looks like a config issue – specifically incorrect/missing project id. Could you please verify your config using the notebook jupyter-examples-1.6.*/configure_and_validate.ipynb?

Please let us know if you still run into errors.

Thanks,

Komal

Good morning Bruce,

This error can be ignored. We will fix this in the next version.

Thanks,

Komal

Hello Bruce,

This is because of an incompatible API change. If you are running JH container, please remove any entries in `/home/fabric/work/fabric_config/requirements.txt’ and restart your JH container via File -> Hub Control Panel -> Stop My Server -> Start My Server.

Compatible versions:

JH 1.5 => fabrictestbed-extensions==1.5.6

JH 1.6 => fabrictestbed-extensions==1.6.2

Thanks,

Komal

@Vaiden

You slice is in state ModifyError For any further modifications to your slice, you need to run the following commands:

slice=fablib.get_slice(name=slice_name)

slice.modify_accept()

Regarding the Authentication Error. Please check if you Bastion key has expired and SSH keys are setup properly. You can use the notebook config_and_validate.ipynb to update/validate SSH keys and your config.

Snapshot of Slice State:

Slice Name: ServiceX_NDN_Proxy_tcp_4nodes Slice ID: 61c1d373-b3b6-472f-a34a-3dd6dac8c809 Project ID: 7a5adb91-c4c0-4a1c-8021-7b6c56af196f Project Name: MF
Graph ID: 34d3dd32-ff1f-4fc2-bad3-c1e542584c9c
Slice owner: { name: orchestrator, guid: orchestrator-guid, oidc_sub_claim: 14098c5d-6c93-4d8a-b67b-a0bbdb765da2, email: William.Logan1@uky.edu}
Slice state: ModifyError
Lease time: 2024-05-18 18:27:07+00:00

Also, looking at /tmp/fablib/fablib.log would provide more information for the failure cause for Authentication error.

Thanks,

Hi Manas,

Thank your for bearing with me. I think I finally have a fix for the issue. I have applied the patch on UCSD and STAR for now and have not been able to reproduce it there.

I would appreciate if you also try at these two sites and share your observation. Hopefully it works consistently now.

Appreciate your help!

Thanks,

Komal
