Tip
titleVSCode and Remote SSH

If you are using Visual Studio Code with the Remote SSH extension, it will not recognise hosts with wildcards as defined in the previous SSH config file.

You may add append an explicit entry for the desired hosts in your ssh config file:

No Format
Host ecs-login hpc-login




SSH connection

MultiExcerptNamessh_standard_connection

Once you have configured the appropriate settings, any SSH-based tools such as ssh, scp or rsync should work out of the box without any additional options.

To test the connection you may ssh into hpc-login if you have access to ECMWF's HPCF:

No Format
ssh hpc-login

Or alternatively, if you only have access to ECMWF ECS service:

No Format
ssh ecs-login

Visit our HPCF User Guide for further information.

Tip
titletsh login every 12 hours

Remember you may need to redo the authentication step for any new ssh connections after 12 hours with:

No Format
tsh login
