Matthieu,<br><br>Sorry about the delay.  Here are the step I usually go through if I am having trouble with ipcluster:<br><br>1.  First, clear out $HOME/.ipython/security<br>2.  Try to create a 1 engine cluster using ipcontroller and ipengine manually (this is what ipcluster uses underneath the hood).  This will help you debug any security related things.<br>
3.  Then move on to ipcluster local and beyond.<br><br>Cheers,<br><br>Brian<br><br><div class="gmail_quote">On Thu, Aug 6, 2009 at 12:07 AM, Matthieu Brucher <span dir="ltr">&lt;<a href="mailto:matthieu.brucher@gmail.com">matthieu.brucher@gmail.com</a>&gt;</span> wrote:<br>

<br>
It seems that it works now, also nothing changed (perhaps a quota<br>
issue in my home folder?).<br>
<br>
I will try to setup the cluster stuff now.<br>

&gt;<br>
&gt; I&#39;m trying to setup ipython 0.10 and test it before submitting a patch<br>
&gt; for LSF support (which is what we are using in Pau instead of PBS).<br>
&gt; This would be my first patch for Ipython (emotion).<br>
&gt;<br>
&gt; So first, I&#39;m trying to get the ipcluster work locally with:<br>
&gt;<br>
&gt;&gt; ipcluster local -n 4<br>
&gt; And the log:<br>

&gt;<br>
&gt; I&#39;ve tried without openssl with ipcluster -xy, but in this case, it<br>
&gt; claimed it couldn&#39;t find furls in .ipython/security/..., and indeed,<br>
&gt; there were none there or in the folder where I&#39;ve started ipcluster.<br>
&gt;<br>
&gt; Is there something I&#39;m missing? I&#39;ve tried following the guide, but no<br>
&gt; success so far :|<br>
