Cannot connect with Rose on ARCHER

Reported by: nfreychet Owned by: ros
Component: Rose/Cylc Keywords:
Cc: Platform: ARCHER
UM Version:



Trying to set the ssh from Puma to ARCHER for Rose. I had the same problem as explained here: http://cms.ncas.ac.uk/ticket/2340

I followed the instruction of this page: http://cms.ncas.ac.uk/wiki/RoseCylc/Hints#Settinguprosehost-selectarcher

When I do the ssh manually (ssh login2.archer.ac.uk), I am asked a password and it works. However when I try to run the Rose command rose host-select archer I still get the error messages ([WARN] login8.archer.ac.uk: (ssh failed) …)

So I wonder if there is anything else to do to configure the ssh connection?

Hi Nicolas,

You need to be able to ssh from PUMA to ARCHER without it prompting for password or passphrase. It sounds from the above, like you haven't got ssh-agent setup properly.

If you have previously setup ssh-keys then you probably just need to add the key to the agent with ssh-add. If that doesn't work then the FAQ here may help: http://cms.ncas.ac.uk/wiki/FAQ_T4_F5

If you don't have ssh-agent set up at all see full instructions here: http://cms.ncas.ac.uk/documents/training/December2017/UM_practicals/getting-setup.html#set-up-an-ssh-connection-from-puma-to-archer

Hi Ros,

Indeed it solved the problem! (I remember I set the ssh-keys before but maybe it's been desactivated somehow).
Thanks for the help!
