fcm make problem on ARCHER

Reported by: cthomas Owned by: ros
Component: FCM Keywords: ssh-agent PUMA
Cc: Platform: ARCHER
UM Version:



I am using a Rose suite to compile NEMO on ARCHER, submitting from Puma. Currently the fcm_make_nemo step, which copies files from the puma repository to a local directory, is failing. I am sure this worked previously (~Dec 2015), since I have binaries that were compiled successfully, and I haven't changed anything since then. I think I have set up the ssh-agent properly, but maybe something changed with the Puma upgrade. I can certainly log into ARCHER without a password, anyway.

This is job.err:

The 'permission denied' message is suspicious. It looks like the script can't create the share/fcm_make_nemo directory. Is there something I need to tweak to fix this? If you need any more information about the suite or fcm options please let me know.

Hi Chris,

Can you please double check that you can login from PUMA to ARCHER without being prompted for either a password or passphrase.

ssh -n -oBatchMode=yes

The following line indicates that it is failing to login to ARCHER successfully with your ssh key.

[FAIL] Permission denied (publickey,keyboard-interactive)

Hi Ros,

That ssh command works if I do this first:

eval `ssh-agent -s`

entering my password when required. I am not sure if that's the recommended method, however.

Hi Chris,

You shouldn't need to do the eval ssh-agent -s line if you have things set up correctly.

You will need to run the ssh-add command after every PUMA reboot and on occasions in between when the ssh-agent decides to die to re-attach the key to your agent.

We have some FAQs here which should help:

Hi Ros,

I can confirm that just using ssh-add (instead of both lines) fixed it.
Many thanks,
