Demo

Here is a demonstration on how to set up Teleport to connect to our our Atos HPCF from a Mac. You can find the step by step guide described below.

Installing the tsh client

...

You may also do it from the command line, as described in the official Teleport documentation:

<div class="preformatted panel conf-macro output-block" style="border-width: 1px;" data-hasbody="true" data-macro-name="noformat

">
<div class="preformattedContent panelContent">
<pre data-bidi-marker="true" id="teleport17-version">TELEPORT_VERSION=17.0.0
curl -O https://cdn.teleport.dev/teleport-${TELEPORT_VERSION}.pkg
sudo installer -pkg teleport-${TELEPORT_VERSION}.pkg -target /</pre>
</div>
</div>

<div class="preformatted panel conf-macro output-block" style="border-width: 1px;" data-hasbody="true" data-macro-name="noformat">
<div class="preformattedContent panelContent">
<pre data-bidi-marker="true" id="teleport13-version">TELEPORT

_VERSION=13.

0.

curl -O https://cdn.teleport.dev/teleport-${TELEPORT_VERSION}.pkg
sudo installer -pkg teleport-${TELEPORT_VERSION}.pkg -target /</pre>
</div>
</div>

Authenticating yourself

...

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.

To test the connection you may ssh into hpc-login if you have access to ECMWF's HPCF:

% ssh hpc-login

Or alternatively, if you only have access to ECMWF ECS service:

% ssh ecs-login

Optional: Automating the authentication step
