#3328 closed help (fixed)

PUMA no longer connecting to ARCHER

Reported by: alwalsh Owned by: um_support
Component: PUMA Keywords: PUMA, ARCHER
Cc: Platform: PUMA
UM Version:



Since PUMA has been put back online after yesterdays maintenance, I can no longer ssh to ARCHER. The ssh command hangs indefinitely and cylc also does not seem to be communicating with ARCHER (cylc job state doesn't reflect actual state of jobs).

I am able to connect to ARCHER locally so believe the issue is with PUMA. Many thanks for any help in resolving this.

Hi Amber,

I can ssh from puma to another server so ssh from puma is working okay. Someone else from the CMS team will need to look at this to see what the issue is.

I have been having the same problem with ssh from puma→archer since yesterday. It was working fine before.
And I can ssh from my local machine to archer ok.

Below is the trace where it hangs when I ssh.

Hi both,

We are looking into this and will update this ticket when we have more information.


P.s Patrick, I've just removed your ssh trace from the ticket for security reasons.

Hi Ros:
Thanks for removing that ssh trace! I wasn't sure if it was a security risk or not.

Hi Amber,

This should be fixed now but please reopen the ticket if it still doesn't work for you.
