From tips of the week, Linux Magazine…
have used the following on a Suse SLES 9 system to make five exact copies of my original server.

On the new server insert the Installation CD and boot to Rescue mode.
Use root to login at the "Rescue" prompt.
Run the following commands:
Ê
# ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up
# ping [...]

Ubuntu | Automatic Update

While searching for ap-get upgrade on the Ubuntu Wiki, I found reference to automatically updating Ubuntu.  I created a script called autoupdt in /etc/cron.daily with the following:

#!/bin/bash
apt-get update
apt-get upgrade -y –force-yes
apt-get autoclean

 Note: I needed to add –force-yes for the upgrade to happen.
This script should keep the Ubuntu computer up to date. 
 

System Backup

RESOURCES
Before I put the new backup server online, I need to back it up. Here's a couple of links that I'm looking into:
Backing up hard disks and partitions
backing up whole /root to tar file
Taring Howto
The idea is to backup the system and save it on the RAID5 Coraid appliance just in [...]

Redirect syslogs to a Server

From RH Knowledgebase 
Issue: How do I redirect syslogs to a single server?
Resolution:
Edit the /etc/sysconfig/syslog file:
SYSLOGD_OPTIONS="-r -m 0"
The -r option allows the system to accept remote log messages.
After the file has been saved, the syslogd service has to be restarted:
# service syslog restart

Redirecting root’s email

Look in your aliases file (/etc/aliases for sendmail) near the
bottom. There is probably a commented out dummy alias for root.
Uncomment it and put the desired recipient address there. Then run
newaliases
You may also need to restart sendmail
service sendmail restart

Copying config.pl Files from Old Server

Instead of recreating the individual config.pl files for each PC to be backed up by BackupPC, I copied the files using scp.  An example of SCP can be found here.  Below are the commands that I issued:
[root@backup comp59]# scp root@photo.cvx.com:/mnt/vol1/backuppc/pc/comp59/config.pl config.pl
root@photo.cvx.com's password:
config.pl                                     100%  158     0.2KB/s   00:00
[root@backup comp59]# ls -al
total 12
drwxr-xr-x  2 backuppc backuppc 4096 May  [...]
