Demo

Here is a demonstration on how to set up Teleport to connect to our our Atos HPCF from your terminal on a Windows 10 or 11. You can find the step by step guide described below.


Installing the tsh client

The tsh application is required to perform user authentication. tsh is open source, very portable, and has minimal dependencies.

First of all, you must download the appropriate Teleport client. We recommend using the latest Teleport service:

<a class="teleport17-version" href="https://cdn.teleport.dev/teleport-v17.0.0-windows-amd64-bin.zip">Teleport 17.0.0 client</a>


You will need to extract the zip file and put the "tsh.exe" executable somewhere in your PATH. The easiest way to do this is to:

  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 Powershell and add to the PATH variable the location of the teleport directory. For example, if you dropped it on your main user directory (C:\Users\yourusername):

    $p=[Environment]::ExpandEnvironmentVariables("%USERPROFILE%\teleport;"); if ([Environment]::GetEnvironmentVariable("Path","User") -notlike "*$p*") {setx PATH "%USERPROFILE%\teleport;%PATH%"}


Authenticating yourself

The following commands need to be run on a Windows Terminal or Powershell

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.

  1. Open the File Explorer and navigate to C:\Users\yourwindowsuser\
  2. If you have a directory called  ".ssh" directory, go inside. If not, you may create it with clicking on "New Folder"
  3. Inside the .ssh directory, check if there is a file called "config".
    1. If config exist, open it with your favourite editor, such as notepad or vscode.
    2. If config does not exist, you can open your favourite editor such as notepad or vscode to create the file and save it later

  4. Add the snipped below in the file you opened. You should replace ecmwfusername by your registered ECMWF user and user.address@somewhere.com  by your registered email address at ECMWF.

  5. Save the file. If you are creating the file from scratch, make sure you save it under C:\Users\yourwindowsuser\.ssh and with the name "config", including the double quotes. The file must not have any extension.
