How do you find your GitLab host name (to test your SSH key)? : <p>I just created a personal GitLab account and am trying to follow the steps on </p>

<p>My GitLab username is <code>khpeek</code>, so I guessed my 'GitLab domain' is <code>gitlab.com/khpeek</code>. However, the test command</p>

<pre><code>ssh -T git@gitlab.com/khpeek
</code></pre>

<p>yields an error message:</p>

<pre><code>ssh: Could not resolve hostname gitlab.com/khpeek: Name or service not known
</code></pre>

<p>Apparently this is the wrong hostname. What would be the right one?</p>
