Authenticating yourself

Multiexcerpt
MultiExcerptNamestandard_tsh_auth

Once every 12 hours, you will need to refresh your tokens with the tsh command. SSH connections may remain active for longer than 12 hours, but new connections will require re-authentication.

To authenticate yourself, open a local terminal and run tsh, giving the location of our Teleport gateway:

tsh login --proxy=jump.ecmwf.int

Your default web browser will open. You should login with your email address, ECMWF password, and then the code from your Time-based One-Time-Password (TOTP) device or the 8-digit one-time passcode from your ActivIdentity (HID) security token if you have not configured your TOTP yet.

Info
titleExisting sessions

If you're already logged in to the ECMWF website, or have recently logged in to this service, the password prompt might be skipped.


Info
titleBrowserless authentication

If your computer does not have a browser or cannot display one, you may use the Teleport SSH access - Browserless Login Python Module for the authentication.

If the process is successful, you will see an output such as:

  Extensions:         permit-X11-forwarding, permit-agent-forwarding, permit-port-forwarding, permit-pty


Tip
titleSubsequent logins

Once you have logged int at least once, tsh will save your proxy settings so you can skip the extra argument next time:

tsh login



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.

...

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.

You can find the right values for those two parameters in the output of the tsh command:
