  1. Open the zip file in your file browser
  2. Drag the teleport folder inside the file and drop into the directory of your choice (the main directory for your user, for example)
  3. Open a Cygwin terminal. 

  4. Add to the PATH variable the location of the teleport directory. For example, if you dropped it on your main user directory (C:\Users\yourwindowsuser):

    No Format
    echo 'export PATH=/drives/c/Users/$USER/teleport:$PATH' >> ~/.bashrc
    source ~/.bashrc


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, Open a local terminal on your MobaXterm 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:

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.

Excerpt

Edit the file ~/.ssh/config on in your cygwin MobaXterm local terminal 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.

Now you should make the tsh internal directory where SSH certificates are generated visible within Cygwin running the following command on a Cygwin terminal:

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

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.

To test the connection, from your Cygwin terminal 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.

Troubleshooting

If you cannot connect via SSH and cannot manage to understand why, please raise an issue to our ECMWF Support portal and sending us the output of the commands:

No Format
tsh login
ssh -v ecs-login
