Twilight Box

Getting Started

In order to play you need to do a couple of things:

• Download a base image. Currently the only one available is a Debian machine (debian.base.img.bz2). It should be about 200MB. (while downloading you can continue to the next point)
• Setup qemu. This should be easy on most Linux Distro. On Debian it is only a question of apt-get install qemu . Remember to install also kqemu. KQemu is a library to accelerate virtualization. AFAIK Qemu is available also Mac OS, but never tried myself. (see Qemu tips below for more info)
• Apart from the base image you will need one (or more ) lvls. You can download lvl0 (50MB). After finishing downloading everything you need to decompress both files in the same directory. Then simply start qemu using as primary disk the base image and as hdb the lvl image. You will also need to setup network in order to play.
• When the boot sequence ends you will be promted some instructions related to the lvl-0. This means you are ready to play

Qemu Tips

If you are not familiar to qemu you can use the script I use to boot the system.

qemu-ifup

 #!/bin/sh

echo "Executing /qemu-ifup.host-only"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br1..."
sudo /usr/sbin/brctl addif br1 $1
sleep 2

start.sh

#!/bin/sh
/sbin/modprobe kqemu

tunctl -t tap1
tunctl -t tap2
ifconfig tap1 up

brctl addbr br1
brctl addif br1 tap1
ifconfig br1 192.168.0.2 


qemu -net nic,vlan=0 -net tap,vlan=0,script=qemu-ifup -net nic,vlan=2 -net user,vlan=2 -hda base.img -hdb lvl0 $@ 


ifconfig br1 down 
brctl delbr br1

make both files executable. Put them in the same directory as the base and the lvl. create a symlink between lvl0 and lvl "ln -s lvl0 lvl" and then run ./start.sh

NOTE:doing this way you are actually creating 2 network interfaces. eth0 will be in bridge with the machine actually running qemu. eth1 is down by default: it is used only to make it simplier to update/create new levels. Eth0 will get its IP from DHCP (if you have a local one on the same machine running Qemu). If it cannot get an address it will default to 169.254.1.2

QEmu on Windows To install qemu on windows I suggest Qemu Manager. It comes with an easy to use interface. I tested and the image is working fine, you should set as network a TAP device (see OpenVPN . It creates a TAP device when you install it).

Hope this is clear enough. If you have any problem go to the Forum
