I'm starting to like CoLinux; I think it's what's going to keep me working next time I'm on the road.
Here's a rough summary of what it took to get the instance that lives on my portable hard disk and runs off a Win2K laptop going ...
Install the Debian image, the TAP driver and interface, and also bridged networking support. Install WinPCap.
Set up /etc/network/interfaces like this:
auto lo eth0 eth1
iface eth0 inet static
iface eth1 inet static
iface lo inet loopback
Put this in config.xml:
<network index="0" type="bridged" name="Wireless LAN" mac="wlan card's mac address here" />
<network index="1" type="tap" name="colinux-TAP" />
(My home network is 192.168.2.* and 192.168.98.* is a fake network to get connectivity between the Linux instance and the Win2K laptop I'm running it on. You might not need the TAP device and eth1 - but if you find you can connect from Linux to the outside world but not the host PC, this will help. I tried DHCP for eth0 originally, but it gave me the address my WLAN card was using under Windows, which didn't work.)
On Windows, edit c:\windows\system32\drivers\etc\hosts and add "192.168.98.2 colinux" at the bottom.
On Windows, rename the TAP connection to "colinux-TAP", change its IP address to 192.168.98.1 and make sure that a default gateway is NOT specified.
Put name servers in /etc/resolv.conf.
update-rc.d -f inetd remove
apt-get install emacs21 apache mysql-server python php4 libapache-mod-php php-elisp python-mode
cp /usr/share/doc/mysql-server/examples/my-small.cnf /etc/mysql/my.cnf
Edit /etc/apache/httpd.conf and change MinSpareServers to 1, StartServers to 1, and MaxClients to 10 (this machine doesn't have much memory).
I've probably forgotten something - but this is most of the "important" stuff :-)
