USB wireless adaptorJanuary 25, 2008
Update: debian contrib does provide the kernel module named rt73-modules-<kernel-version-arch> (arch=686 in my case) and rutilt packages.
To configure the Level One WNC-0301USB 802.11bg wireless dongle.
Many places, e.g. linuxwireless, lists the chipset inside as ZyDAS 1211 . This misinfo sent me off wasting couple of hours wondering why the zd1211rw driver didn’t work. Not until the device ID was examined, had it became apparant that the chipset inside was actually Ralink 2573.
Vendor=148f ProdID=2573 Rev= 0.01
Product=802.11 bg WLAN
The corresponding driver is rt73. It’s a legacy driver and only CVS tarball is available. (Btw, there is an effort in linux-kernel git tree to provide a unified driver rt2x00 to support all ralink wireless devices. However, that driver, included in 2.6.24 is still too experimental at the time of writing.) While at the download page, I also grabbed RutilT, a wireless configuration utility, which turns out to be quite handy. To compile the rt73.ko kernel module, I need kernel-headers. One shortcut is to use module-assistant
apt-get install module-assistant
Although module-assistant doesn’t have rt73 as an opition, I used it to prepare the necessary compile environment (just lauch it and choose “prepare). It will downlaod linux-kernel-headers.
cd rt73-cvs-xxxx/Module; make; make install
It will place the firmware file rt73.bin under /lib/firmware and rt73.ko under /lib/modules/2.6.xx-x/extra.
cp /lib/modules/2.6.xx-x/extra/rt73.ko /lib/modules/2.6.xx-x/kernel/driver/net/wireless
The dongle should be recognized and the wlan0 interface should be opened.
To complie Rutilt
./configure.sh --launcher=nopasswd; make; make install
Chinese fonts in DebianNovember 13, 2007
Desired effect: Everything (menu, console, etc.) in default locale (i.e. English). Able to display Chinese web page and emails nicely. Switchable Chinese input for any application. References , , . and  (for scim setup).
1. generate locales
en_US.UTF-8 as my default locale.
deb http://apt.debian.org.tw/ unstable main/ttf-arphic-newsung to
/etc/apt/sources.list. ttf-arphic-newsung appears to be the font edited by firefly.
Install these essential Chinese fonts
apt-get install ttf-arphic-newsung
apt-get install ttf-arphic-ukai ttf-arphic-uming
apt-get install ttf-arphic-gbsn00lp ttf-arphic-bkai00mp ttf-arphic-bsmi00lp ttf-arphic-gkai00mp
Optional English fonts
apt-get install ttf-bitstream-vera ttf-dejavu
apt-get install msttcorefonts
I don’t recommend editing the font.conf and local.conf as suggested in Ref 4, since doing so will render the English fonts ugly. IMHO, the Chinese fonts, with anti-aliasing, look just as good, if not better, without the modification.
3. scim input set up
apt-get install scim scim-pinyin
4. creates ~/.xinput.d/en_US symbolic link to /etc/X11/xinit/xinput.d/scim.
im-switch -z en_US -s scim
It will complain about not finding scim-pinyin configuration, but works correctly after next login.
elog 2.7.0 in DebianNovember 12, 2007
Unfortunately Elog did not pass the security scrutiny of Debian yet. Hence it is categorized as unstable. For security reason, instead of
apt-get install elog from sid, It’s better to get the latest tarball and build from source.
1. Build and install elog to the default location /usr/local/ with user:group as
cd elog-2.7.0 && make && sudo make install
2. Take care of user privilege
useradd -G staff gordon
chmod -R g+w /usr/local/elog
add to the [global] section of /usr/local/elog/elogd.cfg
Usr = gordon
Grp = staff
3. Start elog daemon and view the logbooks @ localhost:8080
sudo elogd -p 8080 -c /usr/local/elog/elogd.cfg -D
Cisco VPN in DebianNovember 12, 2007
Connecting to the WUSTL NIL VPN service. A good tutorial can be found here .
apt-get install vpnc
sudo cp /etc/vpnc/example.conf /etc/vpnc/nil.conf
Fill in all the information in the conf file with the help from .pcf file, and comment out the line with “IKE Authmode hybrid” because “vpnc was built without openssl: Can’t do hybrid or cert mode.”
sudo vpnc nil.conf
JRE and flash plugin for Mozilla (Firefox/Iceweasel)November 11, 2007
Currently both JRE5 and JRE6 are viable options. Install either one from the non-free section
apt-get install sun-java5-jre
apt-get install sun-java6-jre
link java plugin library to mozilla plugin directory, e.g., JRE6.
ln -s /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so ~/.mozilla/plugins/libjavaplugin_oji.so
This works only for i386. On amd64 system
apt-get install java-gcj-compat-plugin
usually gives most people what they want. If it’s necessary to run sun java-plugin on amd64, a chrooted ia32 env is probably the only solution.
to have flash plugin, which is only available from the unstable (sid) branch
apt-get -t sid install flashplugin-nonfree
to use predefined priorities to automatically select one implementation of “flash”
between the multiple installed alternatives (this usually works for most people)
update-alternatives --auto flash-mozilla.so
to manually select one implementation of “flash” between the multiple installed alternatives :
update-alternatives --config flash-mozilla.so
