Compiling kernel for Vortex86dx

Published on Sunday, May 10, 2009

Update: I've written up a short tutorial on the method I used to install Debian 5.0 on this device.

A few months ago I purchased the eBox-3300 from WDL Systems. The system was promptly shipped, and there were no "gotchas" from WDL. The little box fit my exact needs - it is small, and built very, very well. I flew back to Australia and, after some trial and error, installed Debian 5.0 on it. For quite some time I was just using the vmlinuz file provided by WDL, which was provided by ICOP (DMP). This worked well, but there were two issues:

1) I couldn't load any modules (e.g. NFS).

2) I received an annoying email from OSSEC every few hours telling me it couldn't find modules.dep.

At the end of last week I finally decided to do something about it, and considering this little box is "x86 compliant", I figured it wouldn't be too hard to create a new package. It has been several years since I last created a self-compiled Debian-packaged kernel, so I decided to document the process for the next time I do it. These steps are really just a summary - but if you have much Linux experience, they should be enough to guide you. If I'm unclear, just send me an email.

Because the eBox-3300 is embedded, I logically decided to create the package on another system. However, I wanted to maximize the chances of it working, so I installed Debian 5.0 in VirtualBox, updated it, and proceeded.

As a prep, you may need to install ncurses-dev and kernel-package in your build environment.

apt-get install ncurses-dev kernel-package

1) Download latest kernel from:

2) Download the DMP provided patch/config file for, copy it to /usr/src. Alternatively, you can borrow my config Make a backup.

3) Untar kernel, cd into the kernel directory. Issue:

make menuconfig

4) Configure kernel. If you used my config file, a lot of these should already be ticked.

a) Load alternative config file, I selected mine as /usr/src/config-, or if you downloaded the one from me, use config-

b) Enable generic x86 support

c) Enable Kernel .config support

d) Device drivers -> Network -> 10 or 100Mbit -> RDC R6040, set at built in

e) Turn off generic IDE support

f) Exit, make sure to save the kernel

g) Verify .config exists. If it doesn't, copy the config-2.6.x.x-vortex86dx file to .config

5) Create the kernel debs. In the kernel directory, issue these commands. This will build the kernel image, the headers, and the modules.

make-kpkg --initrd kernel_image kernel_source kernel_headers modules_image

6) Make coffee

7) Copy the debs to your running ebox by sftp (or usb, or whatever is available)

8) Install kernel in eBox-3300

dpkg -i linux-source-
dpkg -i linux-headers-
dpkg -i linux-image-

9) Reboot. If you want my compiled kernel/sources/header .DEBs, just shoot me an email and I'll make them available.

Summary: My only gripe about this little box was the lack of an easily customizable kernel, but no more. I'm still very happy with this $150 purchase.

Fixing locale errors in Ubuntu 8.04

Published on Sunday, May 3, 2009

I've hit this problem a few times, and figured I'd leave a note for myself how to fix it. Ubuntu 8.04 seems to hiccup sometimes (on a VPS) for generating the correct locales. In particular, I get this error, a lot:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Normally I just do 'dpkg-reconfigure locales', but with 8.04, this doesn't seem to do squat. The solution is to edit the /var/lib/locales/supported.d/local file, and insert the correct locales (it will normally not exist, so create it):

# cat /var/lib/locales/supported.d/local
zh_TW.UTF-8 UTF-8
zh_TW BIG5
en_US.UTF-8 UTF-8
en_US ISO-8859-1
en_US.ISO-8859-15 ISO-8859-15

You can then do a 'dpkg-reconfigure locales' and they will be generated correctly. For a list of supported locales, try this:

cat /usr/share/i18n/SUPPORTED | grep US

Fixing mysql warning message

Published on

After restoring databases from one server to another I sometimes get this error on Ubuntu or Debian:

error: 'Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)'

This makes a lot of sense, and the solution is pretty simple. If you look in:

cat /etc/mysql/debian.cnf

You'll see the defaults for your system. Copy the password listed there, and open a connection to MySQL as root (or some other user). Next, enter this (lets say your password specified in debian.cnf was 'abracadabra':

mysql> select PASSWORD('abracadabra');
| PASSWORD('abracadabra')                   |
| *38794E19D534EBA4F0F78903FA00F1DA2989DCA2 | 
1 row in set (0.00 sec)

Next, since we already have the prompt open, do this command:

mysql> USE mysql;
mysql> UPDATE user SET password='*38794E19D534EBA4F0F78903FA00F1DA2989DCA2' where user='debian-sys-maint';
mysql> FLUSH privileges;

Restart MySQL, and the error should have gone away.
