Installing the tsh

The tsh
application is required to perform user authentication.
tsh
is open source, very portable, and has minimal dependencies.
If you have homebrew installed in y our mac, then you can get tsh
installed easily with:

brew install teleport |
Using package installer
Go to the Alternatively, go to the Teleport website and make sure you download the "tsh client" instead of "Teleport Connect".
Authenticating yourself
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, run tsh
, giving the location of our Teleport gateway:

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.

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

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:

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.
