How I Got Zethereal-1.0-arm Up On Oz3.5.3 Solved

[mcdelroy]

Below are the steps I took to get Zethereal-1.0-arm up on OZ 3.5.3. While not perfect they wored for me. It appears the documentation at
http://www.irongeek.com/i.php?submenu=zaur...zaurus/sniffers
may work on OZ 3.5.1 but it contains large gaps with OZ 3.5.3 due to changes in OZ 3.5.3 Feel from to post this anywhere it would be of help.

Getting Zethereal-1.0-arm Running on OpenZaurus 3.5.3

First install libqt_mt3_3.3.3-r5_arm.ipk
It must be installed into ram.

To do so save the file to the sd card. With OpenZaurus 3.5.3, when transferred a *ipkg file via syncing from Qtopia 1.7 on Windows the file is saved to /media/card/Documents/application/ipkg

Issue the following command to install libqt_mt3_3.3.3-r5_arm.ipk in the directory it is saved in.

ipkg –force-depends –d ram install libqt_mt3_3.3.3-r5_arm.ipk  <enter>

Next create a link with

ipkg-link add libqt_mt3_3.3.3-r5_arm.ipk <enter>

Now install task-opie-minimal_1.0.3_arm.ipk with the following

ipkg  -force-depends –d ram install task-opie-minimal_1.0.3_arm.ipk  <enter>

There is no need for a ipkg-link with task-opie-minimal_1.0.3_arm.ipk

Install opie-sh_1.2.0-r0_arm.ipk with

ipkg  -force-depends –d ram install opie-sh_1.2.0-r0_arm.ipk  <enter>

Next create a link with

ipkg-link add opie-sh <enter>

We now need to install libpcap0.8_0.8.3-r0_arm.ipk with the following

ipkg  -force-depends –d ram install libpcap0.8_0.8.3-r0_arm.ipk <enter>

No ipkg-link is needed.

Now install libpcap0_0.7.2_arm.ipk with

ipkg  -force-depends –d ram install libpcap0_0.7.2_arm.ipk <enter>

This installs the libpcap0_0.7.2 files into /media/ram/packages/usr/lib However, OpenZaurus needs links located in /usr/lib to the files in /medial/ram/packages/usr/lib Create the links with the following:

Cd into /media/ram/packages/usr/lib and make sure libpcap0_0.7 files are located there.

Cd into /usr/lib and issue the following command for each libpcap0_0.7.2 file

ln  -s /media/ram/packages/usr/lib/”libpcap0_0.7.2 file name” <enter>

Reboot and make sure the links are still in place.

There is no need for ipkg-links with libpcap0_0.7.2

To work around the quickexec not found error when installing sharp-compat-libs we need to do the following:

Cd into /media/ram/packages/etc/init.d/ and see if quickexec is there.

To create a link to /media/ram/packages/etc/init.d/quickexec in /etc/init.d issue the following command

ln  -s /media/ram/packages/etc/init.d/quickexec /etc/init.d <enter>

Now install sharp-compat-libs_0.5-r2_arm.ipk with the following

ipkg   -force-depends –d ram install sharp-compat-libs_0.5-r2_arm.ipk <enter>

Now cd into /etc/init.d and delete the link to quickexec

Create a link for sharp-compat-libs with the following command

ipkg-link add sharp-compat-libs <enter>

Install libglib_1.2.0_arm.ipk with the following

ipkg  -force-depends –d ram install libglib_1.2.0_arm.ipk <enter>

This installs libglib_1.2.0 files to /media/ram/packages/home/root/usr/lib/ However OpenZaurus needs links to these files located in /usr/lib

Cd into /media/ram/packages/home/root/usr/lib/ and make sure that there are libglib_1.2.0 files located there. The following files should be present.

libglib-1.2.so.0
libglib-1.2.so.0.0.10
libgmodule-1.2.so.0
libgmodule-1.2.so.0.0.10

Create the links by cding into /usr/lib and issue the following for each libglib_1.2.0:

ln –s /media/ram/packages/home/root/usr/lib/”libglib_1.2.0  file name”

Such as

ln -s /media/ram/packages/usr/lib/libglib-1.2.so.0
ln -s /media/ram/packages/usr/lib/libglib-1.2.so.0.0.10
ln -s /media/ram/packages/usr/lib/libgmodule-1.2.so.0
ln -s /media/ram/packages/usr/lib/libgmodule-1.2.so.0.0.10

We still need libglibthread files so Install libglib1.2_1.2.10-9_arm.ipk by doing the following

ipkg  -force-depends –d ram install libglib1.2_1.2.10-9_arm.ipk <enter>

This installs libglib1.2_1.2.10-9 files to /media/ram/packages/usr/lib

However OpenZaurus needs links in /usr/lib to the files in the /media/ram/packages/usr/lib location

Cd into /media/ram/packages/usr/lib and confirm that the following files are located there:

libgthread-1.2.so.0
libgthread-1.2.so.0.0.10

cd into /usr/lib and create links for the libglibthread files with the following commands

ln -s /media/ram/packages/usr/lib/libgthread-1.2.so.0
ln -s /media/ram/packages/usr/lib/libgthread-1.2.so.0.0.10

Reboot and make sure the links in /usr/lib are still present.

You can now install zethereal_1.0_arm.ipk with the following command

ipkg  -force-depends –d ram install zethereal_1.0_arm.ipk <enter>

Create a link for zethereal with

ipkg-link add zethereal-1.0 <enter>

Reboot and follow the instructions at http://opie.handhelds.org/cgi-bin/moin.cgi...dcompat_20HowTo

On how to start Zethereal using the oz-compat (sharp-compat libraries).

Note: Zethereal did not appear to function with new libglibs and libpcap so use the versions mentioned in this document.

When using zethereal you may find that it starts more reliably via the zethereal-1.0-arm command rather then the icon.

Zethereal does not place the nic in monitor mode. To place the nic in monitor mode you may need to first open zethereal via the zethereal-1.0-arm command. Then without closing zethereal open a second console session and issue the following command

ifconfig wlan0 down

iwpriv wlan0 monitor 2 x  <enter>

         where x=the channel you wish to monitor

Check that the nic is truly in by issuing

iwpriv wlan0|more   <enter>

You should see monitor mentioned in the output

Bring the nic up with the ifconfig wlan0 up command. Close this console session and re-enter zethereal.

Under the capture tab make sure that wlan0 is chosen for the nic, enter a maximum number of packets, and click start.

Note: The packet view under the dissect tab does not update in real time. When the capture completes or after you click stop re-entering the dissect tab will show the packets captured.
