C1000/3x00 General discussions / Anyone Syncing To Linux?
« on: March 14, 2005, 10:33:03 am »
There is a pinned file about syncing a C3000 to Windows XP but does anyone have experience on syncing to Linux?  

I will die and go to heaven if I can sync to Evolution 2.0 on Ubuntu but will settle for anything I can get.  Unless all I can get is Windows, in which case I will die and go to hell.

Security and Networking / A Zaurus Mystery
« on: March 06, 2005, 09:38:18 am »
So I was walking through Akihabara today and dropped in the Linux Cafe for a coffee and some WiFi.   Akihabara, if you don't already know, is the computer Mecca of Tokyo and there really is a Linux Cafe although really it is just a rebranded Pronto.  Pronto is a chain of coffee shops a bit down scale from Starbucks but with free WiFi.

So anyway, I fire up my C3000 and try to log on.  Now I've done this before and it has always worked.  The required ESS is pronto but otherwise, the settings are standard Non-ESS, Any, Any.  Automatic DHCP, no WEP, no PPoE, yadda yadda.  Only this time it doesn't work.

I ask this older guy with a WinXP laptop what WiFi settings he is using.  Even with my bad Japanese and his worse English we confirm that my settings are right.  Hmmm.  OK, I decide to ask two younger guys at the table next to me. Each of them is using a W2K laptop and both have browsers open.  They must know something.  Their English is ever so slightly better but they still seemed a bit confused by something.  And this is the comedic bit.

After they looked over my WiFi settings and said yes, it should work, they did something that could only happen in Japan.  Both of them reached into backpacks under the table and pulled out a Zaurus.  The pudgy, shaggy haired guy pulled a C3000 and the gaunt, shaggy haired guy an 860.  In the States, what are the odds that you would run into one stranger with a Zaurus, much less two?

So here is the mystery part.  They fired up and opened networking and each had the same settings.  Three Zauruses (two C3000s and an 860) with three different known-good WiFi cards.  None of the Zauruses are getting online even though all have in the past.  But the three laptops, which are all using the same settings as the Zauruses, are on without a problem.  What gives?  Laptops good, Zauruses bad?

Just in case a little more technical detail will help, here is the setup at the Linux Cafe.  Two large rooms, each with a Toshiba WiFi access point.  One room has an ESS of pronto and the other of tsunami.  I ran Kismet to check the settings and I could see both of them with heaps of packets and good signal strength.  No WEP.  One thing I did notice with the Zauruses is that when you initiated the WiFi connection it would briefly (maybe two seconds) recognize the correct ESS but then flip to 'Unknown' ESS and lose the connection.

Anyway, after 20 minutes, I gave up on this, finished my coffee and walked out the door. On the way out I passed another guy with a Zaurus (an 860 I think) setting up.  I just kept going.

C1000/3x00 General discussions / Request For C3000 Dict2
« on: March 02, 2005, 07:19:35 am »
I am trying to rebuild my C3000 after a factory reset and need to reinstall the dict1 and dict2 directories.  I can only find one of the two CDs that came with my Z so I have dict1 but not dict2.  If someone could zip it for me, an easy way to move files is a website called


C1000/3x00 General discussions / Mammothrept's Notes On Debricking A C3000
« on: February 26, 2005, 03:38:35 am »
Mammothrept's Notes on Debricking an SL-C3000.  The hard way.

Once upon a time (yesterday), I tried to get a KWINS CF card modem working on my Zaurus SL-C3000 but somewhere along the line, it froze.  I could not get it to shut down so I pulled the battery out. Bad move.  When I tried to restart, the Sharp splash screen would come up and hang.  Forever.  No turning it off without pulling the battery again.

I noticed that at the bottom of the Sharp splash screen that there was a little bit of flickering.  On very close inspection, the flickering was actually a rapidly cycling line of text from a Linux kernel panic.  Something about not finding a PCMCIA file.

After reading through the OE Forums and Trisoft's manual I came to the conclusion that the most likely way to get unbrick my Zaurus was to do a factory reset and recustomize everything (and no, of course I did not have a recent usable backup).

So, I set out to reset and reconfigure my Zaurus and to keep detailed notes as I went along as well as assembling a repository of all files I was downloading.  If, someday, disaster strikes again, I want to be able to undig the hole faster.  While these notes are for reconfiguring after a reset, they may also be useful as a distelled set of mini-HOWTOs for common C3000 customizations.

Most of these notes are a rewrite of things I found on Google and the forums.  If it looks like something you wrote, it probably is.  If it looks wholely original, I probably screwed something up.

Please post corrections in this thread.  If there is enough interest, I will post a revision of these notes which incorporates corrections.

10.    UNZIP


See Trisoft's English language manual for the C3000 for detailed and graphical instructions (Page 20-21).

The short version:

Unplug AC power cord from C3000.
Remove battery for about 30 seconds.
Replace battery (replace battery cover, lock cover), and plug in AC power.
Press and hold the "OK" button on the keyboard.
Turn power on.  Japanese language text box will appear with questions.
Select option 3 (Reset)
Select option 1 (Normal)
Select left box (Yes).
Wait as the Zaurus reboots.


I need to be retain the Japanese language capabilities of the C3000 so the most common method or converting to English (mcconvert) is out.  I do use mcconvert just briefly at the beginning to set up the initial Internet connection but I delete it once is run.

   Install mcconvert from for quick and dirty conversion to English.

   Set up wireless card and get online.
   Download from
   (A much better conversion that leaves the Japanese abilities intact.)

   Uninstall mcconvert


One side effect of using for the English conversion is that the Sharp terminal program disappears.  You will regularly need access to the command line so immediately after using, install another terminal program from

To get USB mouse functioning:

Go to

Get latest version of inputhelper.  Currently 1.0.0-1

    * Version 1.0.0 inputhelper_1.0.0-1_arm.ipk


Install most recent version of Kino 2: kino2_0.4.2_arm.ipk
Also install mplayer-bvdd_1.0.1-1_arm.ipk   - (New mplayer package)
Also install bvdd_0.1.0-1_arm.ipk - video driver for C3000
Also install sudo:
(Your Zaurus will reboot as soon as you finish installing the new video driver.  You should notice
an improvement in USB mouse responsiveness.)


(Note 1. When networking with the home LAN, I use a Buffalo CLT LAN card.  You could use WiFi but
my WiFi access point is built into our cable modem and it is outside my LAN's firewall.)

To get SMB (Samba) file sharing working:

(Note 2.  I could not get the smbmount package from Nayno to work correctly even though it is
supposed to be for the SL-C3000.

Get smbmount and libncurses from

Open a terminal.  Use SU to get root.  Create a mount point.  
The share I want to mount is //myserver/public so I created a mount point on my Zaurus of:
    /hdd3/Documents/LAN (all future shares will get mounted off of this)
Next, I created:

The syntax that works for me is:
   smbmount //myserver/public /hdd3/Documents/LAN/public username=(mysername),workgroup=(myworkgroup)

Your newly mounted share should show up in the Files tab inside the "lan" folder.


I have heard that Opera 7.55 works on the SL-C3000 but I could not get it to do so.  What does
work in part is Opera 7.30.  First, read:

Then, from the same page download and install these files:


After installing these files, you will discover at least three limitations.  You cannot make Opera run as root.  The second and third problems are that while you can change the home page from the original and create bookmarks, once you close and restart Opera, all of your changes are gone.  I still cannot get bookmarks to save but you can fix the other problems.  

To do this, go to the "Tab Settings" manager in Settings and create a new launcher.  The new icon will settings will be:

Name: Opera
Icon: (browse to the Opera icon)
Program: opera

Save and go over to the Applications tab.  You should now have two launchers for Opera.  The one you just created can now be set to run as root by holding the stylus down on it until an options box comes up.  By setting Opera to run as root, it will now retain homepage settings.  Not secure, but more convenient.


Before starting, note that you will need a text editor.  The one that comes with a stock Zaurus is lobotomized so it cannot see system files.  You will need to know how to use a command line text editor like VI or use a real graphical text editor like Zeditor.  See Section 2 above (KO/PI PIM AND MISC UTILITIES) for instructions on downloading Zeditor.

Now to start installing Kismet:

First, read
Pay most attention to Kerensa's post #12.

Second, install Kismet,Kismet-qt, libpcap, and libstdc++.  Use these versions:

Third, setup a network connection

   Name: AdHoc for Kismet
      ESS-ID: any
      Network type: Ad-Hoc

      Select 'Specify' IP Address:
      Subnet Mask:

Fourth, use a text editor (running as root) to edit this file:
Make sure the source line looks like this:


* This source works for my Buffalo WiFi card but you may need to select a different source line depending on which WiFi card you use.  A number of commonly used source lines are already in the kismet.conf file.  To enable one, remove the # character at the beginning of the line.  If you are changing the source line from one to another, make sure that you comment out the first one (i.e. add the # character).  You can only use one source line at a time.

Fifth, make kismet_qt run as root.  
To do this, open a terminal and use SU to get root.  Then type:

    chmod 4755 /usr/bin/kismet_qt

Sixth, connect to the network service you created and then launch kismet


Remote desktop application for the C3000.

First, read

 qtrdesktop_1.2.0_arm.ipk ( 37.78k )

Download from
It installs but have not tested yet.  Looks like portrait mode only.


Unzip for the zaurus console.
Download and install


Batteryplus is an applet that gives more information about your battery status than the stock Sharp applet and also lets you change some settings.  Download from bottom of page at:

The page is all in Japanese but the applet is in English.


C1000/3x00 Hardware / Power Limit Using Usb And Cf?
« on: February 26, 2005, 12:54:11 am »
I am starting to suspect there is a limit on the power output of an SL-C3000 that makes it dicey to run a USB mouse, USB keyboard and CF card at the same time.  It does not always happen but sometimes the USB keyboard is either not detected or the character mapping is way off.  I think it is only happening when using all three are plugged in simultaneously.  Anyone else seeing this?

Accessories / Solar Charger For Sl-cxxx
« on: December 06, 2004, 09:54:31 pm »
I am using a solar charger with an SL-C3000.  The charger is from Violetta and it has a USB output: Violetta VS-1 and it is connected to the Zaurus with a USB to Zaurus DC power input cable.

So far, everything is fine but both the Zuarus and the charger are new.  Are there any power issues that can creep up over time?  Is using an external charger risky for Zaurii?
