A few links of tools I find quite useful. Burning new copies for the CD case I carry around.

I needed to copy some computers. At work we use Altiris (now owned by symantec), but it was acting up yet again. I needed something easy to use, fast, and free. At work, we had used Ghost before getting Altiris, but what we have is so outdated, it isn’t worth using anymore. Thank goodness for clonezilla with DRBL, a spare HP D530, extra ram, and a 500GB hard drive.

To make things simpler, I installed Ubuntu 10.04 desktop, 40GB sda with / and swap, and a 500 GB /home/partimag . DRBL recommends disabling updates. this is acceptable since it won’t bet connected to the internet after setup. I assigned the onboard NIC (eth0) to 192.168.69.254 and the second NIC (eth1) to use DHCP for internet connection.

All those installation instructions pretty much boil down to this…

edit apt sources
sudo gedit /etc/apt/sources.list

add either the NCHC source or the sourceforge source. I used NCHC.
deb http://free.nchc.org.tw/ubuntu lucid main restricted universe multiverse
deb http://free.nchc.org.tw/drbl-core drbl stable

Import key
sudo wget http://drbl.nchc.org.tw/GPG-KEY-DRBL
sudo apt-key add GPG-KEY-DRBL

Alternative sourceforge source
deb http://archive.ubuntu.com/ubuntu lucid main restricted universe multiverse
deb http://drbl.sourceforge.net/drbl-core drbl stable

Import alternative sourceforge key
sudo wget http://drbl.sourceforge.net/GPG-KEY-DRBL
sudo apt-key add GPG-KEY-DRBL

Update apt package list and install drbl
sudo apt-get update
sudo apt-get install drbl

Setup / finish installing DRBL
sudo /opt/drbl/sbin/drblsrv -i
Friendly note: netboot images aren’t really needed if you’re just using this as a ghost replacement. Save yourself the download time.

Configure DRBL
sudo /opt/drbl/sbin/drblpush -i

Configure boot
sudo /opt/drbl/sbin/dcs

Since I’m sharing this box with coworkers, I wrote a few small scripts for common settings that would be set with dcs.

I had an issue with video not displaying on a specific model of laptop (HP/Compaq 6710b). I modified the pxelinux.cfg/default to remove nomodeset from the boot options. I was able to use it again!

I’m not sure if the pxelinux.cfg/default or /opt/drbl/conf/drbl-ocs.conf made the change persistent across configuration changes.

XRDP is pretty cool! It’s an RDP to VNC gateway… The second link is where things get really cool. It can connect to VNC sessions on other computers! I now have something to do with my wyse RDP terminal that doesn’t require a windows box. :-)

Project Requirements
At work we needed a time lapse camera of our new student center construction project. It needs to run continuously for entire length of construction project – approx 18 months. It should run mostly unattended.

Features
It captures 1 picture every 5 minutes. Storage capacity is cheap, so after using excel to make some projections, this worked out to be a reasonable rate for our resources. After some more research, I came to the conclusion that flash video has compatibility with most visitors while being relatively bandwidth efficient, but other codecs could be used. I originally got the idea from http://mydebian.blogdns.org/?p=261 but it wasn’t quite awesome enough, so I rewrote using Perl and expanded upon it. Continue reading »
