This guide explains how to build and set up
a DDE-based network card driver
with Debian GNU/Hurd,
if your (wired) network card
is not supported by the old in-kernel drivers shipped with gnumach.

This guide assumes that you have
an installation of Debian GNU/Linux on the same machine,
which helps in fetching the required packages
in absence of working networking in the Hurd.
The whole process is much more cumbersome otherwise.

If you haven't: install hurd to partition
get grub image
boot hurd in single user (change grub entry accordingly to the installed partition)

> $ export TERM=mach

> $ ./native-install

reboot to other debian

suppose hurd partition is hdd1

as root

> $ mount /dev/hdd1 /mnt -t ext2

> $ cd /mnt/etc/apt

> $ echo "deb http://ftp.debian-ports.org/debian unreleased main" >> sources.list

> $ echo "deb-src http://ftp.debian-ports.org/debian unreleased main" >> sources.list

> $ echo "deb http://ftp.uk.debian.org/debian unstable main" >> sources.list

> $ echo "deb-src http://ftp.uk.debian.org/debian unstable main" >> sources.list

> $ wget http://www.gnu.org/software/hurd/hurd/running/debian/DebianAptOffline/apt.conf.offline

> $ cd /mnt

> $ apt-get -c etc/apt/apt.conf.offline update

> $ apt-get -c etc/apt/apt.conf.offline upgrade

> $ apt-get -c etc/apt/apt.conf.offline install git-core

> $ apt-get -c etc/apt/apt.conf.offline build-dep hurd gnumach

> $ apt-get -c etc/apt/apt.conf.offline install build-essential libpciaccess-dev libpcap0.8-dev

> $ cd /mnt/home

> $ git clone git://git.sv.gnu.org/hurd/incubator.git -b dde hurd_dde

> $ git clone git://git.sv.gnu.org/hurd/gnumach.git -b master-user_level_drivers gnumach_dde


suppose you need forcedeth driver

Download http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.29.y.git;a=blob_plain;f=drivers/net/forcedeth.c;hb=HEAD from mozilla like
browser to /mnt/home as forcedeth.c

reboot back to hurd (multiuser)

> $ apt-get update

> $ apt-get upgrade

> $ apt-get install git-core

> $ apt-get build-dep hurd gnumach

> $ apt-get install build-essential libpciaccess-dev libpcap0.8-dev


> $ cd /home/gnumach_dde

> $ autoreconf -i && ./configure --enable-kdb --enable-device-drivers=none --enable-lpr --enable-floppy --enable-ide

> $ make

> $ cd ../hurd_dde

> $ cp -r dde_pcnet32 dde_forcedeth

> $ cd dde_forcedeth

> $ rm pcnet32.c

> $ cp /home/forcedeth.c ./

> $ sed -i 's/pcnet32/forcedeth/g' Makefile

> $ sed -i 's/pcnet32/forcedeth/g' .gitignore

> $ sed -i 's:-lhurd-slab:../libhurd-slab/libhurd-slab.a:' Makefile

> $ sed -i 's:-I/include:-I..:' Makefile

> $ nano forcedeth.c

add this line after the last #include

    #include <ddekit/timer.h>

> $ cd ..

> $ git add dde_forcedeth

> $ git commit -a -m 'Add forcedeth driver'

> $ autoreconf -i && ./configure

> $ mkdir -p hurd/include/ddekit

> $ make libddekit libmachdev devnode pfinet

> $ cd libdde_linux26

> $ make

> $ cd ../dde_forcedeth

> $ make

If the make fails it might be necassary to replace some of the -l options (or all) in Makefile with the real path to the library objects (example: change *-lhurd-slab* to *../libhurd-slab/libhurd-slab.a*)

> $ cp /home/gnumach_dde/gnumach /boot/gnumach_dde

> $ mkdir /hurd/dde

> $ cp /home/hurd_dde/devnode/devnode /hurd/dde

> $ cp /home/hurd_dde/pfinet/pfinet /hurd/dde

> $ cp /home/hurd_dde/dde_forcedeth/dde_forcedeth /hurd/dde/forcedeth

reboot to hurd with the new gnumach_dde

> $ settrans -c /dev/forcedeth /hurd/dde/forcedeth

> $ settrans -c /dev/eth0 /hurd/dde/devnode -M /dev/forcedeth eth0

> $ settrans -c /servers/socket/2 /hurd/dde/pfinet -i /dev/eth0 -a 192.168.1.194 -g 192.168.1.254 -m 255.255.255.0 


replace the ip, gateway and mask with your own ones

> $ nano /etc/resolv.conf

add line: nameserver 192.168.1.254
