</I>&gt;<i> &gt; &gt; The Mageia packages repository will be stored on valstar. As the
</I>&gt;<i> &gt; &gt; repository will be needed on build nodes, it will have to be either
</I>&gt;<i> &gt; &gt; mirrored or mounted via nfs (readonly). If we use nfs, I think we should
</I>&gt;<i> &gt; &gt; first setup a firewall before installing the nfs server. 
</I>&gt;<i> &gt; 
</I>&gt;<i> &gt; While I agree with the firewall part, NFS and portmap are not really
</I>&gt;<i> &gt; very firewall friendly, as there is ( or used to be ) by default dynamic
</I>&gt;<i> &gt; ports involved. We can fix them of course but this has to be taken in
</I>&gt;<i> &gt; account. 
</I>&gt;<i> &gt; 
</I>&gt;<i> &gt; So wouldn't it be easier to use a simple http source ?
</I>&gt;<i> &gt; This would also open less ports on the firewall, les thing to check and
</I>&gt;<i> &gt; supervise, and less work on writing puppet manifests.
</I>&gt;<i> &gt; 
</I>&gt;<i> &gt; ( and I will not add the fact that I deeply hate nfs for the amount of
</I>&gt;<i> &gt; work it gave me on the Mandriva cluster )
</I>&gt;<i> 
</I>&gt;<i> Yes, using http would be more simple, good idea. Is http sources
</I>&gt;<i> supported in Iurt ?
</I>
I don't want to say NFS is wonderfull, but being able launch &quot;rpm -Uvh
libfoo*.rpm&quot; saved my life so many time I really think having the tree
provided by NFS would be an advantage (even ro).

About the firewall part, why not simply allowing everything from ours IP
(the 4 or 5 servers we have) ?
I don't imagine this would be more risky than having php on our
server...

Regards.
