[ppy] Jonathan and I had actually decided to put this onto a 
different box ... (you're going to like this) ...    (03)

Instead of newell.cim3.com (ref: 
http://chm.cim3.net/forum//nls-restore/2005-06/msg00022.html#nid02), 
we'll now be using:    (04)

Hostname: pascal.cim3.com
    (we'll give this the alias nls01.cim3.com & nls01.cim3.net)
Ext IP address: 64.62.192.13 & 64.62.192.14 (.14 for nls01 use)
Hardware: IBM e326 Dual Opteron 250 2 x 2.4GHz
            - 1 MB cache processor SMP
Memory: 8GB ECC SDRAM
OS: GNU/Linux - Fedora Core 4 distribution (FC4-x86_64)
Kernel: 2.6.11-1.1369_FC4smp    (05)

I'll let you guys know when the box is at the cim3-fmt1 colo 
facility. We'll be getting 100Mbps full burstable bandwidth into 
a multi OC-48 self-healing fiber ring backbone.    (06)
