(firstly, DHCP server/client is nice and easiest but not necessary)


Taken from a post i made in the following thread, inspired by an earlier post in the same thread by NickNak introducing me to this method, but whose guide didnt work for me (telemetric_au).


The setup i got it working under is fairly common, but im confident it would also work with many others...

  • an ADSL Router/Hub/DHCP server connected to
    • a PPC Debian etch box via USB
    • and i386 Debain etch box via ethernet (also worked under sid)
      • which is in turn connected to my 5500's USB cradle


Contents

Step #1

  • On your Z's "Host Box" run from a command prompt (ctrl+alt+F1); ctrl+alt+F7 switch's to X, and ctrl+alt+F10 switch's to System Messages (handy for checking your z is recognized apon plugging in) ;) 
apt-get install bridge-utils

(which gives you the "brctl" command used bellow)


Step #2

  • Edit the file /etc/network/interfaces using a text editor running with root (su) access as shown below, without changing anything else (i.e. other interfaces) which are allready there but are not mentioned or adjusted in the following box of code, substituting the X's with your choice of IP. 
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network/internet interface
auto eth0
iface eth0 inet static
address 0.0.0.0
netmask 0.0.0.0

# The Virtual Bridging Interface linking usb0 to eth0
auto br0
iface br0 inet dhcp
pre-up brctl addbr br0
pre-up brctl addif br0 eth0
post-down brctl delbr br0

# The Zaurus's Connnection
allow-hotplug usb0
mapping hotplug
script grep
map usb0
iface usb0 inet static

# The following is a dummy address/netmask,
# and is only used initially to create the usb0 interface,
# so it can then be set to 0.0.0.0 just like eth0 :)

address 192.168.X.X
netmask 255.255.255.X
post-up ifconfig usb0 0.0.0.0 up
post-up brctl addif br0 usb0
post-down brctl delif br0 usb0


Optionally if you didn't want to use DHCP or dont have it running switch the setup code for br0 from above with the following, substituting the X's with your choice of IP. 


# The Virtual Bridging Interface linking usb0 to eth0
auto br0
iface br0 inet static
address 192.168.X.X
netmask 255.255.255.X 
pre-up brctl addbr br0
pre-up brctl addif br0 eth0
post-down brctl delbr br0

Step #3

  • Restart your networking system, without rebooting, by executing the following command line. 
/etc/init.d/networking restart


Step #4

  • Configure your Zaurus

now depending on which ROM your running, the changes you may need to make may be different...

if you have an /etc/network/interfaces file, edit it as follows:

For auto dhcp assigned address add/edit: 

iface usb0 inet dhcp

For a static IP address add/edit: 

iface usb0 inet static
#your z's address
address 192.168.X.X
#your computer's address (this will most likely be the address for br0,
#but may instead be usb0 if you needed to make usb0 static for some reason...) 
pointopoint 192.168.X.X
netmask 255.255.255.X
