Earlier I wrote about my proposed Tactical Network Security Monitoring Platform. Today I finally sat down and installed the operating systems I need on this system to create a portable tactical forensics and investigation platform. I did not want to use my main work laptop for this sort of work because I do not administer it. I needed my forensics platform to be separate from the corporate domain and totally under my control. I only feel comfortable attesting to the configuration of a system doing forensics if I built it from the ground up and I am the sole administrator.
For operating systems, I had three needs. I wanted Windows XP because the majority of commercial forensics software runs on Windows. I wanted Ubuntu Hardy Heron so I could have access to Linux forensics software and VMware Server. (Windows is also a possible VMware Server candidate, but I might install a copy of VMware Workstation on the Windows side.) I wanted FreeBSD 7.0 in case I needed to do packet capture and related network security monitoring tasks.
I decided to triple-boot these three operating systems. The box has three logical hard drives. Two are physical (147 GB each) and the third is a RAID 0 array resulting in a single HDD of 447 GB.
Before I got the following to work I had to experiment with various setups. The following is what I settled upon. I'm posting this information for future reference and for those who might want to try the same setup.
First I installed Windows XP on the only HDD it could see, one of the 147 GB HDDs. I thought this a little odd, but it suited my purposes. I rebooted and Windows started without incident.
Next I changed the default boot drive in the BIOS from the Windows HDD to the next HDD. I installed Ubuntu Hardy Heron Desktop on that second 147 GB HDD. I selected the "Advanced" option and told Ubuntu to install its bootloader into one of the drives (/dev/sdc, which turned out to be a problem) I was using for Linux.
When I tried rebooting, GRUB had created entries for Linux and Windows but neither worked. I realized for some reason the way the drives were ordered on the Ubuntu live CD/installer wasn't the same way they were seen by GRUB (or by Linux, once booted). I figured out this was the problem and manually changed the GRUB command line to boot properly into Linux. I needed to implement a similar fix for Windows. I'll show what the result was shortly. I made the changes to GRUB permanently before going to the next step.
Finally I installed FreeBSD 7.0, which saw the remaining 447 GB HDD as /dev/da0 and the other HDDs as /dev/ad4 and /dev/ad6. I didn't touch /dev/ad4 or /dev/ad6 but installed the FreeBSD bootloader into /dev/da0.
After a reboot I had to try various combinations to get GRUB to properly boot FreeBSD 7.0, but eventually I got that working too.
Here is how Linux's fdisk -l saw the computer:
Here is the GRUB menu I got working:
I'll probably resize the Windows partition and add a D: drive. I just noticed I devoted the whole drive to C: during installation.
Update: I wasn't able to use the version of GParted available through Ubuntu (0.3.5 I think) to resize the C: partition but I did use the latest stable liveCD (0.3.6-7) to resize C: and create E: (D: was already the optical drive).
