Description

My user ID is sseshasa and I recently set up vpn access to sepia lab.
I am getting the following error when I run teuthology-lock from teuthology.front.sepia.ceph.com

NOTE:
- I have copied the id_rsa.pub from my laptop to ~/.ssh directory on teuthology.front.sepia.ceph.com
- The above is the same key I submitted for getting vpn access.

Here's the error from the teuthology-lock command,

sseshasa@teuthology:~/teuthology$ ~/teuthology/virtualenv/bin/teuthology-lock --lock-many 1 --machine-type mira | tee ~/targets.yaml

The above SSH protocol banner error keeps showing up in a loop. I tried running the above command multiple times but get the same error.
I suspect something is wrongly configured. Therefore, I am not certain if this is a bug and am raising a support ticket.

Please let me know if my configuration is proper and how to fix this.

Thanks!
