Setup your SSH config

We strongly recommend setting up all the SSH options needed for the connection instead of passing them on the command line.

Excerpt

Edit the file ~/.ssh/config on your computer and add the snippet below. You may create it if it does not exist. You should replace ecmwfusername by your registered ECMWF user and user.address@somewhere.com by your registered email address at ECMWF.

SSH 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.
