Debian (USB w/ DHCP and Bridging)
(Setup you Zaurus to connect a network and internet via yor host box.)
Revision as of 23:37, 28 April 2006
(firstly, DHCP server/client is nice and easiest but not necessary)
(secondly, in all examples replace X 's with you choice of suitable/relevant IP's)
(thirdly, if your running pdaxrom, youll most likely have to transfer all config file to you pc for editing via which ever means possible, as i couldnt get "vi" to work properly...)
(fourthly, if your running some wacky old kernel and your z doesnt show up in usbview or in the system messages display when you plug it in, then youll need to look into building/installing some modules mentioned in Generic (USB) another paper as its not covered in this one...)
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
Step #1 - Install "bridge-utils" package
- On your Z's "Host Box" run from a command prompt:
note: (ctrl+alt+F1) switch's to shell; 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
(this gives you the "brctl" command used bellow)
Step #2 - Edit /etc/network/interfaces
- Edit the file /etc/network/interfaces using a text editor running with root (su) access as displayed below, without changing anything else (i.e. other interfaces) which may allready be there but are not mentioned or adjusted in the following box of code.
# 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.
# 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.)
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 GUI network setup interface use that:
check the automatically bring-up option if present set ip address, subnet, gateway, dns's as needed (with gateway being your pc's br0 IP (or usb0 or possibly even the eth0) IP *(not the router's) its a bit hard for me to be sure on the topic of static IP's as i only used it initially very shortly in OPIE...
- if you dont have a GUI or prefer not to use one and 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
- if you dont have an /etc/network/interfaces file but have an /etc/hotplug/usbdnet.conf file such as in pdaxrom edit it (either on your pc or via "vi" from the base root prompt (before pdaxrom) )
#IP=192.168.X.X #NETMASK=255.255.255.X DHCPS=no I DHCPC=yes
#IP=192.168.X.X #NETMASK=255.255.255.X DHCPS=no DHCPC=no
- Specify the Zaurus's DNS if not allready specified with for example a GUI
edit /etc/resolv.conf to add the IP of your DNS server as found in your PC's /etc/resolv.conf which in my case was the router's address
Step #5 - Take a break
it hopefully should be all working sweet now internet included, so go lie down and get to sleep early for a change ;)
if not try contacting me via the oesf forums for some assistance if i can be of any...
here is a copy of my system messages from insertation through to IP assignment:
