SSH connection to slice nodes, failed

[Meshal Alruwisan]

Hello,

I can not SSH or execute commands to all the nodes in slice: a336a5f3-266b-438f-8759-8a13f50fc8e

Although, I can SSH to nodes from other slice. I tried manually connect to one of the nodes in this slice and I got this error:

Warning: Permanently added ‘bastion.fabric-testbed.net’ (ED25519) to the list of known hosts.
Warning: Permanently added ‘2610:e0:a04c:fab2:f816:3eff:fe97:33ab’ (ED25519) to the list of known hosts.
ubuntu@2610:e0:a04c:fab2:f816:3eff:fe97:33ab: Permission denied (publickey).

How can I fix this issue?

 

Thank you in advance.

If I understand the problem from the description correctly (“manual connect”), you’re trying to connect to the VM(s) from a terminal on your computer/laptop and getting the error. If that’s the case, you need to set up your ssh client configuration file and ssh keys properly (in your computer/laptop) and connect. This page can be helpful -> https://learn.fabric-testbed.net/knowledge-base/logging-into-fabric-vms/

If my understanding is wrong and problem is something different, please disregard the info above.

Yes, I meant SSH using terminal. I am able to connect to other VMs using the same PC. I only have issue with this slice. Since I am able to connect to other VMs I do not think I have issues with keys/configurations. Is there another solution I could try?

Thank you,

So, since you’re able to login to this problematic VM from other sources, then you can check and make sure the right SSH key is inside the VM. I just placed my SSH key in it, and I could login properly. Please let us know about the status following your SSH key check and I will take a look further.

Thank you, I was able to ssh using slice>connect to VM ” with generating new key” and I added the public key myself. For all the VMs except “Spine12” I got the error below. Management IP Address: 2610:e0:a04c:fab2:f816:3eff:fe41:d076

 

Error reading SSH protocol banner

 

How can I solve this issue?

 

Thank you.

Not sure what happened, but I am able now to connect to all the VMs and it is fixed.

Thank you Mert for the help.

Best regards,

Meshal
