Updated for OZ 3.5.1
Website: http://www.openzaurus.org
Packages: http://www.openzaurus.org/official/unstable/3.5.1/
Upgrades like OpenSSH: http://www.openzaurus.org/official/unstable/3.5.1/upgrades/
Install Guide: http://openembedded.org/oe_wiki/index.php/OpenZaurusInstallGuide

     The OpenZaurus ROM gives you more options than the Sharp ROM, and it's said that OZ has better hardware support. It's fairly easy to install, just copy the root file system (opie-image in my case, renamed to initrd.bin) and kernel (zImage) you want to a CF card and hit the hard reset button while holding down C and D on the keyboard (if you have big paws it can be tough). See the install Guide linked above for more details.

Package Management:

     You can add packages by put them on an SD/CF card and using the Package Manager app or the ipkg and ipkg-link command line tools. The GUI Package Manager seems to be largely fubared as far as finding packages on CF cards goes, so I recommend using the command line tools. The basic syntax is as follows (after you change to the directory the package is in):

To install to ram:

ipkg -d ram install Whatever-Package3.3_60.ipk

To symlink it into the root file system:

ipkg-link add Whatever-Package-shortname

If you don't know the short name of a package run the following command and look though your options:

ipkg list

If you get tired of seeing portmap error use the following command to get rif of portmap:

ipkg remove portmap

     In OZ 3.5.1 Many of the apps on these pages will need LibPcap to function, but it seems to be installed by default with OZ 3.5.1. Before you install any of the Packages I have mirrored  please check in the directories ( http://www.openzaurus.org/official/ ) at the OpenZarus site to see if there are any newer versions available.

     One downside to OZ 3.5.1 is that it was built with a newer version of gcc then a lot of the apps compiled for the Sharp ROM which means you will need the compatibility libraries from http://www.mithis.com/zaurus/ipkgs/. A newer version of the package for OZ 3.5.1 can be found here: oz-compat_0.5-r0_arm.ipk. You will know when you have a compatibility problem when you get an error like "undefined symbol: _7QString.shared_null". The GUI tool that comes with the compatibility libraries does not always seem to work so what I do is edit the .desktop files and add "runcompat" in front of whatever the exec= line points to (see my example in the Zethereal section). Update 3/15/2004: Tim Ansell (aka Mithro) of the OZ-compat project sent me the following notes that might help you with GCC compatibility problems:

 

Hi!

I was reading your oz-compat pages (as I like to look at how people are using my packages) and found the following information:

"The GUI tool that comes with the compatibility libraries does not always seem to work so what I do is edit the .desktop files and add "runcompat"

in front of whatever the exec= line points to (see my example in the Zethereal section). "

There is actually a better way to do this, if you go to the console and do a "makecompat <binary>" it will link up that binary to the compat libs.

I would also like to know more information on where that script fails so I can fix it :)

I really need to do a quick C++ application instead of being horrible dependent on the old and unmaintained opie-sh. (I plan to eventually rework and replace opie-sh with a better opie-sh :)

Anyway I thought i would just inform you of this :)

Thanks

Tim aka Mithro

Some general tips:

1. Make sure you have a good text editor like Nano installed so you can edit system files, the text editor from the GUI is flaky as hell.

2. The first thing you you should do after installing OZ is give the root account a password using the passwd command.

3. Fn-C acts as Ctrl-C would on the desktop.

4. Make sure you have a good SSH and SFTP program on you box. In Windows I use Putty for SSH and FileZilla for SFTPing files. I use EditPad Lite for editing system files on my Windows box, it does not screw up Unix style line feeds. Also, upgrade to OpenSSH instead of Dropbear on your Zaurus so you can do SFTP.

5. Keep the backlight low to extend battery life and have suspend mode only turn of the LCD when you are wardriving.

6. Space is limited, get yourself an SD card to log information to.

7. My old instructions say to install LibPcap, almost all of these apps will need it, but with OZ 3.5.1 it seems to be installed by default.

  Change your MAC Address

Here is how to change you MAC address in OpenZaurus. Iuse these two commands:

ifconfig wlan0 down hw ether 0:0a:0a:a0:a0:a0
ifconfig wlan0 up

This would set you wlan0 interface to use the MAC 0:0a:0a:a0:a0:a0. This could be useful for sniffing other connections or for bypassing MAC address restrictions on an Access Point (find valid MAC addresses by sniffing them). It also makes it less traceable to your hardware.
