&gt; Hi Everyone,<br>
&gt;<br>
&gt; Does anyone know how to prevent the use of passwordless ssh keys? I want to<br>
&gt; prevent users authenticating without a password.<br>
&gt;<br>
&gt; In fact if anyone know of any ssh policing tools/faqs that would be really<br>
&gt; usefull. I find it simple securing a server, but when you have 100&#39;s of<br>
&gt; linux desktops I&#39;m unsure on the best way to stop users leaving ssh-agent<br>
&gt; running all the time or using passwordless keys.<br>
&gt;<br>
&gt; Discussion/advise appreciated.<br>
<br>
</div></div>I have had a write up about this for some years:<br>
