How to REMOVE an ssh key from a Summit Xxxx in extreme OS 21


Hey, I inadvertently
uploaded a bad public key for my user account. (and to associate with
admin account)

Try as I might, I cannot "fix" it. I can't find a
way to delete it, and re-uploading the correct key has no effect - I still have the bad key embedded...

Any ideas who I might talk to about this? I've just spend HOURS pouring over the documentation and googling my brains out.. Can't find the solution.

Thanks for your time - not a big deal, but irritating, none the less..

Sincerely,

-ET-

That is the INCORRECT KEY.. my bad, but perhaps I can over write it and start over again?

That's the CORRECT key.. I've double checked on unrelated systems..

reboot the switch:

Hi Eric,

Welcome to the Hub...

You can use the below command to delete the user-key.

"Switch.1 # delete sshd2 user-key "
Thanks! That worked perfectly, and PROBABLY is obvious in the documentation and I just didn't see it..

Appreciate your time!

That's what the Hub is here for Eric. It takes a Community to run a modern network.

Thanks for your trust in Extreme and as Karthik said -- Welcome to the Hub! We're glad you joined us.
