i'm not ignoring all of the suggestions so far (i'm taking note of
all of them) but as rp herrold suggests, a lot of this is getting
pretty far afield, so let me drag this back on-topic.

Dear all,

And how about Serial Over LAN using IPMI if your kit supports it? Very
useful is you've broken things... (speaking from experience :-)

I recently came across a replacement for /dev/urandom called frandom

To bring some closure to this thread,
I'm playing with software RAID and LVM in some virtual machines and
I've run into an issue that I can't find a good answer to in the docs.
I have the following RAID setup:
md0: sda1 and sdb1, RAID 1. This is /boot
md1: sda2 and sdb2, RAID 1. This is a PV for LVM.
VolGroup00, this is the volum

Entering those commands exactly worked, but I'm not sure why it
worked. So, it's progress.
I need to find some good reference on GRUB, which seems difficult
because most things I can find are about GRUB2, and CentOS has 0.97

Hello,
Is there any maximum number of IP aliases or IP ranges that ifup can
handle? Right now i have about 12000 IPs assigned to the server and when
trying to assign range number 47 (ifup eth0-range47), i get his error:
/etc/sysconfig/network-scripts/ifup-post: line 21: 12733 Segmentation
fault
Are there any 64bit CentOS5 kernels available that are immune against
the exploit mentioned in the subject? Turning off 32bit support is no
option to me..

about firewalls, but I don't really want to run another machine at
this time. OpenDNS is trivi
