Hi guys, I managed to restart id_rsa_archerum, so that I have marc@puma:/home/marc/roses/u-ck231> ssh-add -l 4096 SHA256:JtBQhDQKIHjiJfutS98+WBmUWfOuoDoPl5BKIXu6NfM /home/marc/.ssh/id_rsa_archerum (RSA) but I’m still failing to submit jobs to login-4c.archer2.ac.uk with job.err output like [WAR…

Hi Marc, What do you get when you type ssh login-4c.archer2.ac.uk on PUMA? Cheers, Ros.

Hi Ros, Thanks for very quick response, I get marc@puma:/home/marc/roses/u-ck231> ssh login-4c.archer2.ac.uk PTY allocation request failed on channel 0 Comand rejected by policy. Not in authorised list Connection to login-4c.archer2.ac.uk closed. Thanks, Marc

Hmmmm, that’s the expected response. Can you give me permission to read your /work and /home directories on ARCHER2 please? chmod -R g+rX /work/n02/n02/marc chmod -R g+rX /home/n02/n02/marc Ta. Cheers, Ros.

Hmmmm I can’t see anything obvious. Have you tried it multiple times and also a rose suite-run --new to clear everything out just in case? Cheers, Ros.

Hi Ros, Yes, I’ve tried both those things. I’m finishing for today, so I’ll see if it works tomorrow. Thanks for looking into it, Marc

Hi Marc, So it works ok for me. My only other suggestions of things to try if it still fails in the morning is to try running the failed fcm command directly on the PUMA command line and see what happens. It also looks like you have 2 ssh-agents running on PUMA and I wonder if that is somehow cau…

Hi Ros, Can I just check, do you mean running something like the following? marc@puma:/home/marc/cylc-run/u-ck230/work/18500101T0000Z/fcm_make_drivers> fcm make -f /home/marc/cylc-run/u-ck230/work/18500101T0000Z/fcm_make_drivers/fcm-make.cfg -C /home/marc/cylc-run/u-ck230/share/fcm_make_drivers -j…

Hi Marc, Yes that was what I meant. Not sure that helped but I’ve just noticed you don’t have an entry for the 4c in your ~/.ssh/config file. Please try adding the following: Host login-4c.archer2.ac.uk User marc IdentityFile ~/.ssh/id_rsa_archerum ForwardX11 no ForwardX11Trusted no Cheers, Ros. …

Thanks Ros, I’ve done this, logged out, restarted ssh-agent and ~/.ssh/id_rsa_archerum, but it’s still failing in the same way. I’ve run out of ideas for the moment. Thanks, Marc
