Tutorial how to get modules working in 2.6.x debian and other images

Why installing modules Edit

Every kernel version needs binary compatible modules. Modules are stored under Linux in directory /lib/modules, a different directory for every kernel version, for exsample the current is /lib/modules/2.6.11-co-0.6.4

All preconfigured coLinux distributions have no modules installed. This let the distribution untouched for newer coLinux versions in future.

CoLinux can run without modules. Mostly wanted devices are included in kernel directly.

Some distributions would give you warning about missing file modules.dep. If you see this message, or if you need some more device drivers (for sample ipv6), then you should install modules.

Modules installs, different ways Edit

Automaticly: initrd.gz installs modules Edit

(version 2.6.2 and later)

  • Fortunately modules are now provided inside an image initrd.gz which you'll find in the C:\colinux directory after installing the snapshot.
  • Modules are supposed to install automatically using the "initrd" mechanism of the XML-file:
<!-- Initial RamDISK (initrd) support -->
<initrd path="initrd.gz" />
  • Or as command line option:
 initrd=initrd.gz
  • After installing modules, you can remove the initrd from your configuration.

manual install modules via cofs Edit

(version 2.6.3 and later)

  • Add your colinux install directory as cofs device to your XML-file:
<cofs_device index="0" path="\DosDevices\C:\coLinux" type="flat" enabled="true" />
  • Or as command line option:
 cofs0=C:\coLinux
  • Start colinux.
  • The cofs is a filesystem and no need modules, and no need entries under "/dev". Simple mount the cofs filesystem read only and unpack the modules:
mkdir /mnt
mount -t cofs -o ro cofs0 /mnt
cd /
tar xzf /mnt/vmlinux-modules.tar.gz
  • Small facelift: Set the user root as owner for all module files and lets modules.dep the last changed file:
chown -R root.root /lib/modules/*-co-*
touch /lib/modules/*-co-*/modules.dep

manual install modules via initrd Edit

If the automatic initrdgz didn't work, you can still install them manually:

First, as initrd.gz is a common name I recommend that you copy it to something like initrd.modules.gz,
unzip it to initrd.modules
then add to your XML-file:

<block_device index="3" path="\DosDevices\C:\coLinux\initrd.modules" enabled="true" />

Start colinux.

mkdir /mnt
mount /dev/cobd3 /mnt   OR   mount /dev/cobd/3 /mnt
cd /
tar xzf /mnt/modules/lib/modules/vmlinux-modules.tar.gz

should do the trick.

manual install modules via smb Edit

The following information is about installing modules in the older official versions <= 0.6.1

You will find the file vmlinux-modules.tar.gz in c:\colinux (installation directory)

I assume that you already have networking working well enough to use apt-get

First we intall sshd before starting this so you have a terminal you can paste into

apt-get update
apt-get install ssh
passwd root (sshd won't let you log in to a passwordless root account

Now lets get a decent editor before nano drives us insane

apt-get install mc

Now edit /etc/apt/sources.list
You have 2 choices:
1: Upgrade to sarge (testing)
replace stable with sarge in sources.list

2: Use backports
Add the following line to your sources.list
deb http://www.backports.org/debian stable kernel-image-2.6.6-i386

Whichever option you chose you now need to upgrade

apt-get update
apt-get dist-upgrade

Now install module-init-tools (forget possible warnings about modconf)

Get access to the modules tarball from linux. the exact means doesn't really matter i used

apt-get install smbfs
mkdir /f
smbmount //plugwashlap/f /f

Change to the root dir and extract the modules tarball

cd /
tar xzf /f/colinux-20040622-bin/vmlinux-modules.tar.gz

Test it
modprobe ip_tables

Facelift: Owner root Edit

  • Small facelift: Set the user root as owner for all module files and lets modules.dep the last changed file:
chown -R root.root /lib/modules/*-co-*
touch /lib/modules/*-co-*/modules.dep

Test working modules Edit

modprobe ip_tables
lsmod

lsmod should show the module ip_tables in list of modules.
