Watchguard XTM 5

Sticker on back says "WatchGuard XTM 5 series XTM 520"

Fairly nifty little box:

• More or less normal x86 Wintel board inside the box
• 1x 10/100baseT port on the front (Labeled "0")
• 6x 1000baseT ports on the front (Labeled "1" through "6")
• 8P8C modular connector serial console port -- and the BIOS is configured for serial port redirection
• 2x USB ports inside
• motherboard has a single Socket 775 Celeron 440 CPU (not very exciting, but this will turn exciting later on)
• 2x DDR2 DIMM sockets
• Compact Flash port (not sure largest capacity suppported -- The WatchGuard OS is delivered on a 1Gbyte CF card.
• 2x SATA (SATA 2, probably, based on age) ports on motherboard.
• 2x SATA power connectors included on the power supply
• 1x DDR2 PC6400 1Gbyte DIMM

Modifications so far

• Replaced DIMM with 2x 1Gbyte PC6400 DIMMs from a Dell Optiplex 740 2Gbytes of RAM
• Removed CF card and make a backup image of its contents.

Stuff on order

• Xeon L5430 processor (4 cores, 2.66GHz clock, 12Mbytes of L2 cache) This is not a socket 775 part, but it is a Socket 771 package. And there are readily available kits for placing a Socket 771 Xeon in a Socket 775 system board.
• Socket 771 CPU -> Socket 775 socket adapter ("Xeon inside" stickers included)
• 4 and 8Gbyte CompactFlash cards

Progress toward Linuxification

• Pulled 1Gbyte Transcend CompactFlash card out, made backup copy of its contents on desktop machine 2016-08-23
• Located a working 160Gbyte 2.5inch SATA hard drive and commenced to wiping it and ...
• debootstraped Debian Jessie onto said hard drive: sudo debootstrap --components=main,contrib,non-free --verbose jessie target
• chroot target bin/bash --login and run

apt-get update
apt-get install bash-completion vim-nox sudo openssh-server
groupadd -g 1000 adj
useradd -u 1000 -g 1000 -s /bin/bash -m adj
passwd adj
dpkg-reconfigure -p low debconf
apt-get install grub-pc
# make GRUB use serial console instead of VGA
apt-get install linux-image-3.16.0-4-amd64

• Pulled hard drive, placed in WatchGuard box.
• Realized totally forgot an /etc/fstab. We'll see what happens without...
• Worse realization: No LVM tools in initramfs. (Seeing as I didn't install them inside the debootstrapped chroot. D'oh!)
• DANGER: Voodoo! Creating LVM logical volume device mapper mappings without the LVM tools is not a good idea (but it works if you have a good reference for the tables somewhere)

(initramfs) dmsetup create vg00-root --table "0 2097152 linear 8:2 2048"
(initramfs) dmsetup create vg00-tmp --table "0 8388608 linear 8:2 4196352"
(initramfs) dmsetup create vg00-var --table "0 8388608 linear 8:2 12584960"
(initramfs) dmsetup create vg00-usr --table "0 8388608 linear 8:2 20973568"
mount -t ext4 /dev/dm-0 /root
mount -t ext4 /dev/dm-1 /root/tmp
mount -t ext4 /dev/dm-2 /root/var
mount -t ext4 /mnt/dm-3 /root/usr
chroot /root /bin/bash --login

(yay for built-in journal playback. And for forgetting to vgchange -an vg00 on the machine that ran the debootstrap.

• Add an entry to /etc/network/interfaces and ifup eth1
• create a good /etc/fstab
• Make sure /boot is mounted (update-initramfs needs to write here)
• apt-get install lvm2
