Hey Soumya Koduri, Are these new/additional or replacement credentials?

They are replacement credentials. Thanks!

Hi Soumya Koduri,

You should have access to the Sepia lab now. Please verify you're able to connect to the vpn and ssh soumyakoduri@teuthology.front.sepia.ceph.com using the private key matching the pubkey you provided.

Be sure to check out the following links for final workstation setup steps:
https://wiki.sepia.ceph.com/doku.php?id=vpnaccess#vpn_client_access
https://wiki.sepia.ceph.com/doku.php?id=testnodeaccess#ssh_config

Most developers choose to schedule runs from the shared teuthology VM. For information on that, see http://docs.ceph.com/teuthology/docs/intro_testers.html

Thanks

Hi Adam,

I am still unable to access the teuthology machines. It throws "teuthology.front.sepia.ceph.com: Name or service not known" error.

The openvpn-client is successfully running but its still not able to resolve the hostname. This issue has come up only after I upgraded my system to Fedora34. Re-creating the credentials hasn't helped resolve the issue. Pasting below my config details. Please let me know what may be the issue here. Thanks!

Hey Soumya, If you re-run the new-client script, It's unfortunately not idempotent so if you re-ran it and still have the output, we'll need the new string it printed. If you don't have the output, please re-run it again and send the new string.

Hi Adam,

Sorry for the confusion. The creds I had provided in this tracker are the current latest ones. However I am still unable to login to machines as it throws error "teuthology.front.sepia.ceph.com: Name or service not known" . Any idea how to resolve the same? Thanks!
