12 Feb 2010 Logon to Norsk Tipping using Ubuntu 9.10
This post is a short howto how I managed to use my Ubuntu 9.10 (Karmic Koala) to log on to the web pages of Norsk Tipping using a USB CardMan 3121 buypass card reader and Firefox web browser.
First of all you need to install Java to login to Norsk Tipping webpages.
# aptitude install sun-java6-jre sun-java6-plugin
I got the following error message while trying to login “Feilreferanse 31503″.
Installing the following packages solved the problem and I am now able to use the webpages to Norsk Tipping just like I do in Windows.
# aptitude install libccid libpcsclite-dev pcscd libpcsclite-dev

19 Jan 2010 Change ethernet settings using ethtool
Force network speed on a network card to 100 MBit Full Duplex and in the same time disable auto negotiation
# ethtool -s eth0 speed 100 duplex full autoneg off
These settings are active until you reboot the machine or restart the network.
In order to keep this change on each system reboot, append the following line in the following Redhat file /etc/sysconfig/network-scripts/ifcfg-eth0
ETHTOOL_OPTS="speed 100 duplex full autoneg off"
An alternative tool to use to change the settings is mii-tool.

17 Nov 2009 Create a temporary “Site Down” notice in Apache
This post describes how to make a “Site down for maintenance” notice using Apache .htaccess and the mod_rewrite module.
I assume you know how to enable the Apache htaccess directive and the mod_rewrite module.
First you need to create a .htaccess file in your root level of your website.
Next you add the following lines to it
Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_URI} !/sitedown.html$
RewriteRule $ /sitedown.html [R=302,L]
The .htaccess file should be “active” immediately and you should see the content of your sitedown.html file. If not, try clearing your browsers cache.
If you as a maintenance user would like to access the site without seeing the sitedown.html file, add the following line to enable IP address exception
RewriteCond %{REMOTE_HOST} !^192\.168\.0\.12
Remember to replace the IP address with your address.
The .htaccess file should now look something like this.
Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_URI} !/sitedown.html$
RewriteCond %{REMOTE_HOST} !^192\.168\.0\.12
RewriteRule $ /sitedown.html [R=302,L]
Just delete the .htaccess file when you are done with your maintenance and your site will be available again.
