PermaLink Test your Wireless Security with Ubuntu 11.1004.01.2012 12:00
I still see several wireless networks with weak or even no security enabled. However if somebody uploads illegally content, like copyrighted movies, you will be held responsible as holder of the internet connection.
As you may not know what kind of security your router has as it has been installed by somebody else or you can't change the configuration you can use a software stack on Ubuntu Linux to test security. Do NOT use this to crack a network you do not own!

PermaLink No sound with AMAROK in Ubuntu Linux 9.10?23.04.2010 10:34
I had a strange problem with AMAROK not playing any sound. Even weird if I used the test-button in the preferences I did hear sound.
After searching the web I found that you have to install this package: libxine1-ffmpeg


PermaLink How to scoll using the Thinkpad Trackpoint28.12.2009 01:00
I really like to scroll using the third/blue mouse key on my Thinkpad. I was missing this feature with Ubuntu Linux and found that this solution also worked for my T60p.

PermaLink Weird problem with Ubuntu Linux and Alice ADSL19.04.2009 18:22
I am currently on vacation in Italy and stumbled apon a weird problem with the network I am using here. While there is no problem using Windows XP, I had massive problems with Ubuntu Linux. I was able to connect using 802.11g WPA2-AES and I was able to make namelookups and ping was working BUT the browser just hang after retrieving a short part of the page and some pages did not load at all. So I had to analyze the problem:
This is an ADSL connection from Alice, the router is a Alice Gate 2 Plus Wi-Fi.
The first thing I checked was the MTU size, it is only 1400 on this network but that's not the problem source.
Finally I found this site explaining the very same problem:
On my Ubuntu 8.10 I added these settings to /etc/sysctl.conf
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_ecn = 0

This fixed my problem. I did not change net.ipv4.tcp_syncookies = 1 as suggested on the linked site.
