			<content:encoded><![CDATA[<p>Default installation of Ubuntu and XUbuntu do not send the hostname to the DHCP server and this prevents other machines on the network from looking up your machine by using the FQDN (Fully Qualified Domain Name). This is easy to fix with a few tweaks to the DHCP configuration file.</p>
<p><strong><span style="text-decoration: underline;">Disclaimer</span></strong>: These steps have worked for me and have been tested on Compaq Evo N610c running Ubuntu 8.04 LTS (Hardy Heron) and Compaq Armada M300 running XUbuntu 8.04 LTS (Hardy Heron). YMMV. I am not responsible for loss of data or damage to computers.</p>
<p>1. Open Terminal Window<br />
2. If you already know your hostname skip to step 4<br />
3. To find your hostname run the following command</p>
<pre>hostname</pre>
<p>4. Make a copy of the existing dhclient configuration file</p>
<pre>sudo cp /etc/dhcp3/dhclient.conf /etc/dhcp/dhclient.original</pre>
<p>5. Edit the dhclient configuration file</p>
<pre>sudo vi /etc/dhcp3/dhclient.conf</pre>
<p>6. Search for the line send host-name (On XUbuntu it is missing completely and you will need to add it in)<br />
7. Uncomment the line and replace &lt;hostname&gt; with the hostname identified in step 3. The line should look similar to</p>
<pre>send host-name "ubuntu-laptop"</pre>
<p>8. Save the file and exit gedit<br />
9. Restart networking</p>
<pre>sudo /etc/init.d/networking restart</pre>
<p>That&#8217;s it &#8230; test if other machines on the network can now look up your machine by using the FQDN. If you notice something wrong you can always restore the original dhclient configuration file.</p>
<p>The above instructions should work for KUbuntu too although I have not validate it myself.</p>

			<content:encoded><![CDATA[<p>Ubuntu 8.10 (Intrepid Ibex) was officially released on Oct-31. Since I had tested<a href="http://www.lucidtips.com/2008/04/26/ubuntu-804-lts-hardy-heron-on-compaq-evo-n610c/" target="_blank"> Ubuntu 8.04 LTS on Compaq Evo N610c</a> I was eager to give Ubuntu 8.10 a spin on the same laptop. I did a fresh install and the installation is very smooth. A seven step wizard guides you through the install process and you are up and running very quick on Evo N610c.</p>
<p>Ubuntu 8.10 core includes GNOME 2.24 desktop which introduces 2 major enhancements - Nautilus file manager now has tabbed support and the File Roller archive manager adds support for ALZ, RZIP, CAB, TAR and 7Z archive types.</p>
<div id="attachment_186" class="wp-caption alignnone" style="width: 310px"><a href="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/ubuntu-810-intrepid-ibex-on-compaq-evo-n610c_file-browser.png" target="_blank"><img class="size-medium wp-image-186" title="File Browser on Ubuntu 8.10 Intrepid Ibex" src="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/ubuntu-810-intrepid-ibex-on-compaq-evo-n610c_file-browser-300x216.png" alt="File Browser has tabbed support on Ubuntu 8.10 Interpid Ibex" width="300" height="216" /></a><p class="wp-caption-text">File Browser has tabbed support on Ubuntu 8.10 Intrepid Ibex</p></div>
<p>Intrepid Ibex includes X.Org 7.4 which is the latest stable and this version addresses the resolution issue with ATI Mobility Radeon 7500. You can now adjust the resolution without making manual changes to xorg.conf file. Extra Visual Effects are also supported.</p>

<p>Ubuntu 8.10 adds Guest session functionality. You can now create a temporary password-less user account. This  temporary account cannot permanently store data and also cannot access any regular user&#8217;s data.</p>
<p><div id="attachment_190" class="wp-caption alignnone" style="width: 127px"><a href="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/ubuntu-810-intrepid-ibex-on-compaq-evo-n610c_guest-session.png"><img class="size-medium wp-image-190" title="Ubuntu 8.10 introduces Guest Session functionality" src="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/ubuntu-810-intrepid-ibex-on-compaq-evo-n610c_guest-session.png" alt="Guest Session creates a password-less user" width="117" height="212" /></a><p class="wp-caption-text">Guest Session creates a password-less user</p></div>
<p>With Ubuntu 8.10 you can create a USB Startup Disk. You have been able to do this with earlier versions too but it is now much easier.</p>
<div id="attachment_192" class="wp-caption alignnone" style="width: 268px"><a href="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/ubuntu-810-intrepid-ibex-on-compaq-evo-n610c_make-usb-startup-disk.png" target="_blank"><img class="size-medium wp-image-192" title="Make USB Startup Disk on Ubuntu 8.10 Intrepid Ibex" src="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/ubuntu-810-intrepid-ibex-on-compaq-evo-n610c_make-usb-startup-disk-258x300.png" alt="Ubuntu 8.10 lets you make a USB Startup Disk" width="258" height="300" /></a><p class="wp-caption-text">Ubuntu 8.10 lets you make a USB Startup Disk</p></div>
<p>Specific to Ubuntu 8.10 on Evo N610c you no longer see the ugly ACPI error messages during boot up. ACPI works much better - the sleep and hibernate functions work correctly. The fan is not on constantly and only kicks in when required.</p>
<p>Ubuntu 8.10 includes the latest 2.6.27-7-generic kernel and the rev 1300 of orinoco drivers for Compaq Wireless LAN MultiPort W200 doe not build correctly. I had to play around quite a bit to get W200 to work and a special patch is required. To help other users I have updated  <a href="https://help.ubuntu.com/community/WifiDocs/Device/CompaqW200" target="_blank">WifiDocs/Device/CompaqW200 - Community Ubuntu Documentation</a>. A patched version of the driver is available <a href="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/11/compaqw200_2627-7-generictar.gz" target="_blank">here</a> for your convenience.</p>
<p>One disappointment I had with Ubuntu 8.10 is that it includes OpenOffice 2.4.1 instead of the latest 3.0 version. However <a href="http://news.softpedia.com/news/How-To-Install-OpenOffice-org-3-0-in-Ubuntu-8-10-96449.shtml" target="_blank">upgrading to OpenOffice 3.0 on Ubuntu 8.10</a> is easy.</p>
<p>Overall Ubuntu 8.10 Intrepid Ibex runs much better on Compaq Evo N610c as compared to Ubuntu 8.04 Hardy Heron. If you enjoy Ubuntu and own a Evo N610c give Intrepid Ibex a try.</p>
<p>Good luck!!!</p>

			<content:encoded><![CDATA[<p>I recently decided to rebuild my trusted little Compaq Armada M300 laptop and thought might give Ubuntu another try. Since the laptop is only 500 Mhz with 128 MB RAM XUbuntu is a better candidate as compared to Ubuntu. My earlier attempt of installing XUbuntu had not been very successful but this time I managed to get things working</p>
<p>I happen to have the optional Mobile Expansion Unit (MEU) for docking the M300 and hence can use the CD ROM drive. If you do not have the Mobile Expansion Unit and have a purely disk less M300 you can still install XUbuntu on it although it is a bit more complicated. See UbuntuGeek&#8217;s post on <a href="http://www.ubuntugeek.com/install-ubuntukubuntuedubuntuxubuntu-without-cdrom-drive.html" target="_blank">Installing Ubuntu/Kubuntu/Edubuntu/Xubuntu without CDROM Drive</a>.</p>
<p>M300 does not have enough horsepower so install via Live CD does not work. Use Alternate install CD instead. During the install process the detection of the network adapter fails. Ignore this error and continue with the install. The rest of the install should go smoothly.</p>
<p>When XUbuntu starts 2 things do not work correctly - the network adapter and the sound card. Both of this can be fixed by loading the appropriate modules.</p>
<p>First step is to identify the type of network adapter and sound card. To do this open the terminal window and run the command lspci</p>
<pre>lucidtipster@lucidtips:~$ lspci
00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (AGP disabled) (rev 03)
00:04.0 CardBus bridge: Texas Instruments PCI1211
00:05.0 VGA compatible controller: ATI Technologies Inc 3D Rage LT Pro (rev dc)
00:07.0 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02)
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01)
00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03)
00:08.0 Multimedia audio controller: ESS Technology ES1978 Maestro 2E (rev 10)
00:09.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 09)
00:09.1 Serial controller: Agere Systems LT WinModem</pre>
<p>The listing above tells us that the network adapter is Intel Pro/100+ Mini PCI Ethernet and the sound card is ESS Maestro 2E sound card</p>
<p>To load the module for network adapter. Open the command prompt and run the command</p>
<pre>sudo modprobe eepro100</pre>
<p>At this time if you do not see any error message your network adapter should be working. If you are configured for DHCP you should have aquired an IP address. To check open the terminal window and run the command</p>
<pre>ifconfig</pre>
<p>If you did get an IP successfully you should be able to browse the internet. If you did not get an IP try running the following commands.</p>
<pre>sudo ifdown eth0
sudo ifup eth0</pre>
<p>Now again check if you have acquired an IP. One down and one to go &#8230; To load the module for sound card open the command prompt and run the command</p>
<pre>sudo modprobe snd-es1968</pre>
<p>If you do not see any error message your sound card too should be working as well. Download <a href="http://www.nch.com.au/acm/sample.ogg" target="_self">sample.ogg</a> to test the sound.</p>
<p>To make sure both these modules are loaded automatically upon system boot up modify the /etc/modules file and add the following lines to it.</p>
<pre>eepro100
snd-es1968</pre>
<p>To edit the /etc/modules file using vi the command is</p>
<pre>sudo vi /etc/modules</pre>
<p>The content of my /etc/modules file is listed below</p>
<pre>lucidtipster@lucidtips:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

loop
lp
fuse
eepro100
snd-es1968</pre>
<p>Lastly my M300 had old BIOS from 1999 and I would get an error message during booting. I managed to fix this by downloading and upgrading to the <a href="http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&amp;cc=us&amp;prodTypeId=321957&amp;prodSeriesId=96234&amp;prodNameId=96720&amp;swEnvOID=1093&amp;swLang=8&amp;mode=2&amp;taskId=135&amp;swItem=PSG_I14326-36004" target="_blank">latest BIOS</a>. This too turned out to be a little tricky because I had to make a bootable CD with the BIOS upgrade on it. If anyone is looking for this CD please leave a comment and I will upload the ISO image of the M300 BIOS upgrade CD.</p>
<p>Good luck!!!</p>

			<content:encoded><![CDATA[<p>One of the cool features of Apple&#8217;s Mac Operating system is the Dock. It is used to launch applications and also switch between running applications. Linux communites like to adopt the good from other operating systems and there are several Docks available for Linux as well. The two popular ones for Ubuntu are Avant Window Navigator (AWN) and Cairo Dock.</p>
<p><strong><span style="text-decoration: underline;">Disclaimer</span></strong>: These steps have worked for me and have been tested on Compaq nc6000 running Ubuntu 8.04 LTS (Hardy Heron). YMMV. I am not responsible for loss of data or damage to computers.</p>
<h2>Prerequisites</h2>
<h3>Check if your video card can support 3D graphics</h3>
<ol>
<li>Click on <strong>System</strong>-&gt;<strong>Preferences</strong>-&gt;<strong>Appearance</strong></li>
<li>Select <strong>Visual Effects</strong> tab</li>
<li>Select <strong>Normal</strong> or <strong>Extra</strong></li>
<li>If you see &#8220;Desktop effects could not be enabled&#8221; message then your video card cannot support 3D graphics and you will not be able to use these docks.</li>
<li>Click <strong>Close</strong></li>
</ol>
<h3>Install compizconfig-settings-manager</h3>
<p>To you use AWN or Cairo Dock you need to have composite manager such as Compiz-Fusion installed. You can install it using Synaptics Package Manager (System-&gt;Administration-&gt;Synaptics Package Manager) OR from the<strong> </strong>command line using the following command (you will be prompted for password)</p>
<pre>sudo apt-get install compizconfig-settings-manager</pre>
<h2>Avant Window Navigator (AWN)</h2>
<p>AWN positions itself at the bottom of the screen and can be used to keep track of open windows and behaves like a normal window list. Appreance and functionality of AWN can be customized via various plugins and applets that are available for download. By default it does not include themes.</p>
<p>AWN Wiki states that the AWN package included in Ubuntu Hardy Heron (8.04) LTS however it is very old and outdated. It recommends using PPA to install the packages instead. To do this edit <strong>/etc/apt/sources.list</strong> file using either vi or gedit and add the following lines</p>
<pre>deb http://ppa.launchpad.net/awn-testing/ubuntu hardy main
deb-src http://ppa.launchpad.net/awn-testing/ubuntu hardy main</pre>
<p>Now you need to update the package cache</p>
<pre>sudo apt-get update</pre>
<p>You are now ready to install AWN</p>
<pre>sudo apt-get install avant-window-navigator-trunk awn-manager-trunk awn-extras-applets-trunk</pre>
<p>Now that AWN is installed you can start it from the menu <strong>Applications-&gt; Accessories-&gt;Avant Window Navigator</strong></p>
<p>To have AWN autostart when you reboot your machine select <strong>Automatically start AWN on login</strong> on the <strong>General</strong> tab of awn-manager.</p>
<h2>Cairo Dock</h2>
<p>Cairo Dock is similar to AWN and can be used to launch application and utilize small applets that reside on the bar. You can attach it to either top or bottom of your screen and is highly configurable.</p>
<p>There are more than one way to install Cairo Dock and the instructions below are for using the repositories. You can also <a href="https://help.ubuntu.com/community/CairoDock#With%20the%20deb%20package%20(stable)" target="_blank">install Cairo Dock with the deb package</a></p>
<p>Similar to AWN Cairo Dock too has its repositories. You first need to download and install the signed key for authentication. This prevents security errors from popping up. Open Terminal Window and run the following command</p>
<pre>wget -q http://repository.cairo-dock.org/ubuntu/cairo-dock.gpg -O- | sudo apt-key add -</pre>
<p>Next edit <strong>/etc/apt/sources.list</strong> file using either vi or gedit and add the following lines</p>
<pre>deb http://repository.cairo-dock.org/ubuntu hardy cairo-dock</pre>
<p>Once again update the package cache</p>
<pre>sudo apt-get update</pre>
<p>You are now ready to install Cairo Dock</p>
<pre>sudo apt-get install cairo-dock cairo-dock-plug-ins</pre>
<p>To run Cairo Dock press Alt-F2 and type cairo-dock</p>
<h2>Minimizing / Closing Bottom Gnome Panel</h2>
<p>If you are going to use AWN or Cairo Dock the default GNome panel at the bottom of the screen is redundant. You can close or minimize it.</p>
<h2>Final Thoughts</h2>
<p>So which one is better - well try both and decide for yourself it ain&#8217;t gonna break anything. My personal preference is Cairo Dock. It is much nicer to use comes with a bunch of themes/launchers that you can use.</p>

			<content:encoded><![CDATA[<p>Hurricane Ike was a major event in South East Texas and I apologize for the off topic post.</p>
<p>My family and me survived the hurricane OK. The house sustained minor roof damage but thanks to modern engineering it was able to withstand strong category 1 (119–153 km/h 74–95 mph) hurricane force winds. We were also not affected by floods. The only problem we have is no electricity, no phone, no internet and the cell phone service is very erratic. Overall we are in much better shape than the rest of Houston and surrounding areas. Driving around you can see all the destruction. TV images do not do justice to what has really happened here.</p>
<p>I do not know when we can expect power but will have my next post up as soon as possible &#8230;</p>

			<content:encoded><![CDATA[<p>In March I had written a post related to <a href="http://www.lucidtips.com/2008/03/01/wireless-using-w200-on-opensuse-103/" target="_blank">Wireless using W200 on openSUSE 10.3</a> which happens to be one of the most viewed entry on this blog. Since I wrote that post openSUSE 11.0 has been released and hence am posting an updated version of this howto.</p>
<p><span style="text-decoration: underline;">Disclaimer</span>:</p>
<ol>
<li>The instructions below have worked for me and tested on Compaq EVO N610c running openSUSE 11.0 (2.6.25.11-0.1-pae). YMMV. I am not responsible for loss of data or damage to your machine.</li>
<li>Using KNetwork Manager with W200 causes system to hang up. Use ifup instead. (On SUSE forums it has been mentioned that my post is wrong and you do not need to disable KNetwork Manager. However I have to admit I have not figured out a way to make W200 work with KNetwork Manager).</li>
<li>I have only tested with WEP. Do not know the status of WPA/WPA2. If you do test with WPA/WPA2 I would appreciate your feedback.</li>
<li>You need to repeat these steps after any kernel updates.</li>
</ol>
<p><strong>Prerequisites</strong></p>
<p>Check your kernel version</p>
<pre>uname -r</pre>
<p>Using YaST Software Management install the following packages</p>
<p>cpp43<br />
curl<br />
gcc<br />
kernel-source<br />
linux-kernel-headers<br />
make<br />
subversion</p>
<p><strong>Configure the kernel</strong></p>
<p>Before we proceed further we need to configure the kernel source</p>
<pre>cd /lib/modules/$(uname -r)/build/
su
(root password)
cp /boot/config-$(uname -r) .config
make oldconfig
make prepare</pre>
<p><strong>Downlading the driver</strong></p>
<p>Download the suitable revision of the orinoco_usb driver from SVN. For me revision 1300 has worked correctly.</p>
<pre>svn co -r 1300 https://orinoco.svn.sourceforge.net/svnroot/orinoco/branches/usb/</pre>
<p><strong>Compile and install the driver</strong></p>
<pre>cd usb
make
sudo make install</pre>
<p><strong>Download the firmware</strong></p>
<p>The firmware directory has a script that makes this task easier</p>
<pre>cd firmware
./get_ezusb_fw</pre>
<p><strong>Copy firmware to appropriate location</strong></p>
<pre>sudo cp orinoco_ezusb_fw /lib/firmware</pre>
<p><strong>Activating the adapter</strong></p>
<p>Almost there &#8230; load driver into the kernel</p>
<pre>sudo /sbin/modprobe -v orinoco_usb</pre>
<p>The tiny green light on the side of W200 should come on. Eureka!!! (if it did not come on, try rebooting)</p>
<p><strong>Disable KNetwork Manager and Configure wireless card<br />
</strong></p>
<ol>
<li>Start YaST and select Network Devices-&gt;Network Settings</li>
<li>You should see &#8220;Compaq WLAN Multiport W200&#8243; listed there with &#8220;Not configured&#8221; in the IP Address column</li>
<li>Before we proceed we need to disable use of KNetwork Manager. Click on &#8220;Global Options&#8221; tab and select &#8220;ifup&#8221; instead of KNetwork Manager</li>
<li>Click on &#8220;Overview&#8221; tab</li>
<li>Select &#8220;Compaq WLAN Multiport W200&#8243; and click the &#8220;Edit&#8221; button</li>
<li>Click on &#8220;General&#8221; tab. Select &#8220;At Boot Time&#8221; under &#8220;Device Activation&#8221;</li>
<li>Click on &#8220;Address Tab&#8221;. Select &#8220;Dynamic Address DHCP&#8221; or Statically Assigned IP Address depending on your network setup.</li>
<li>Click on &#8220;Next&#8221; button</li>
<li>On Wireless Device Settings select &#8220;Managed&#8221; under &#8220;Operating Mode&#8221; and other options to match your network settings (reminder I have only tested with WEP. If you do test with WPA/WPA2 do send me your feedback)</li>
<li>Click &#8220;Next&#8221; button</li>
<li>Click &#8220;Finish&#8221; button</li>
</ol>
<p><strong>Configure Wireless Connection</strong></p>
<p>Now you need to configure the wireless connection and since we have disabled KNetwork Manager all this needs to be done via command line. It is very easy to do and the command that does this is iwconfig.</p>
<pre>iwconfig &lt;interface&gt; essid &lt;ESSID&gt; key &lt;wirelesskey&gt; mode &lt;managed|master|secondary|ad-hoc|monitor|repeater|auto&gt;</pre>
<p>Example (Open Terminal Window and run)</p>
<pre>sudo /usr/sbin/iwconfig eth1 essid "Linksys" key abcd1234 mode managed</pre>
<p>susegeek has a good post on <a href="http://www.susegeek.com/wireless/iwconfig-wireless-interface-configuration-utility-in-linux/" target="_blank">using iwconfig to configure wireless</a>.</p>
<p>You now need to stop start your wireless card for the changes to take effect. Open Terminal Window and run</p>
<pre>sudo /sbin/ifdown eth1
sudo /sbin/ifup eth1</pre>
<p><strong>Testing</strong></p>
<p>Open Terminal Window and run</p>
<pre>/sbin/ifconfig</pre>
<p>to see if you have obtained IP address.</p>
<p>The final step of the journey is to make sure you can surf the internet. To truly test this we should disable the wired network card</p>
<pre>sudo /sbin/ifdown eth0</pre>
<p>Now see if you are able to traceroute</p>
<pre>/usr/sbin/traceroute www.google.com</pre>
<p>If you did not get any errors you should be able to launch Firefox or Konqueror and surf your favorite web sites.</p>
<p><strong>Prevent KNetwork Manager from auto starting</strong></p>
<p>KNetwork Manager hangs while using W200. I have not been able to figure out how to get W200 to work with KNetwork Manager. In SUSE forms it has been mentioned that my instructions are incorrect and KNetwork Manager does work with W200 if you use wpa_supplicant package. I would appreciate if someone could tell me how <img src='http://www.lucidtips.com/wordpress/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> I can update this post entry which could help other openSUSE users as well.</p>
<p>To prevent KNetwork Manager from auto starting when machine is started open the Terminal Window and run the following command</p>
<pre>sudo mv /opt/kde3/share/autostart/knetworkmanager-autostart.desktop $HOME/</pre>
<p><strong>Modify boot.local file</strong></p>
<p>In my testing I noticed that when the laptop was rebooted the DNS settings would not stick. I got around this by modifying the /etc/init.d/boot.local file</p>
<pre>sudo vi /etc/init.d/boot.local</pre>
<p>and add the line</p>
<pre>/sbin/dhclient eth1</pre>
<p>Save the file and reboot the laptop and ensure you are able to connect to the internet via the wireless card.</p>
<p><strong>Final Thoughts</strong></p>
<p>I am not sure why I had to run iwconfig in addition to wireless card configuration made via YaST. Maybe just running dhclient would have sufficed but the steps above are the sequence I followed and it worked out all right. I would appreciate your feedback. Good luck!!!</p>

			<content:encoded><![CDATA[<p>As the name suggest Load Balancing is simply spreading the work load between two or more backend servers. Load Balancing can be used for any kind of server - HTTP, SMTP, POP/IMAP, DB. There are several open source software load balancers available but for the purpose of this post we will look at Pen and Balance.</p>
<p><strong><span style="text-decoration: underline;">Disclaimer</span></strong>: These steps have worked for me and have been tested on Compaq Evo N610c running Ubuntu 8.04 LTS (Hardy Heron). YMMV. I am not responsible for loss of data or damage to computers.</p>
<p>The packages for both Pen and Balance are available for Ubuntu (both packages are available for OpenSUSE as well). You do not need both Balance and Pen. Either one of them will work. I have included instructions for both so you can test them yourselves and decide which works best.</p>
<h3>Installing Balance on Ubuntu</h3>
<p>Balance is simple but powerful generic tcp proxy with round robin load balancing and failover mechanisms. It is Open Source Software and released under GPL licensing terms. <a href="http://www.inlab.de/" target="_blank">Inlab Software</a> the developers of Balance also have a commercial version called <a href="http://www.inlab.de/balanceng/index.html" target="_blank">BalanceNG<sup>®</sup></a></p>
<p>To install Balance run the following command (see <a href="http://picasaweb.google.com/lucidtips/SettingUpALinuxBasedSoftwareLoadBalancer/photo#5237406065447956050" target="_blank">screenshot</a>)</p>
<pre>sudo apt-get install balance</pre>
<h3>Using Balance</h3>
<p>It is very easy to use Balance. The syntax is</p>
<pre>balance port host1 host2</pre>
<p>So if you wanted to setup load balancing for two machines that run Apache the command would be</p>
<pre>sudo balance -df 80 192.168.1.105 192.168.1.108</pre>
<p>The -df tells Balance to display debugging and tracing information messages on the screen and to stay in the foreground. Note we need to run using sudo because we are trying to access ports lower than 1024. (see <a href="http://picasaweb.google.com/lucidtips/SettingUpALinuxBasedSoftwareLoadBalancer/photo#5237406070047784386" target="_blank">screenshot</a>)</p>
<p>To use failover mechanism the you need to specify the failover host</p>
<pre>sudo balance -df 80 192.168.1.105 192.168.1.108 ! 192.168.1.110</pre>
<p>See <a href="http://www.inlab.de/balance.pdf" target="_blank">Balance Manual</a> for more information</p>
<h3>Installing Pen on Ubuntu</h3>
<p>To install Pen the command is (see <a href="http://picasaweb.google.com/lucidtips/SettingUpALinuxBasedSoftwareLoadBalancer/photo#5237406065027756178" target="_blank">screenshot</a>)</p>
<pre>sudo apt-get install pen</pre>
<h3>Using Pen</h3>
<p>Pen usage syntax is very similar to Balance</p>
<pre>pen port host1 host2</pre>
<p>To setup load balancing for two machines that run Apache the command would be</p>
<pre>sudo pen -df 80 192.168.1.105 192.168.1.108</pre>
<p>The -df displays debugging and tracing information messages on the screen and stay in the foreground. Note we need to run using sudo because we are trying to access ports lower than 1024. (See <a href="http://picasaweb.google.com/lucidtips/SettingUpALinuxBasedSoftwareLoadBalancer/photo#5237406068653772690" target="_blank">screenshot</a>)</p>
<p>See <a href="http://siag.nu/pen/" target="_blank">Pen web site</a> for more information</p>
<p>Though Load Balancing as listed above is not suitable for Production systems it certainly is helpful if you are developing software and want to test how it would behave behind a load balancer.</p>

The <a title="Fix screen resolution in Ubuntu - ATI Radeon Mobility 7500" href="http://www.lucidtips.com/2008/05/24/fix-screen-resolution-in-ubuntu-with-ati-radeon-mobility-7500/" target="_blank">resolution fix for ATI Mobility Radeon 7500</a> did not help either. I recently managed to get Compaq nc6000 that uses ATI Mobility 9600 video card and Advanced Desktop Effects worked correctly.</p>
<p><strong><span style="text-decoration: underline;">Disclaimer</span></strong>: These steps have worked for me and have been tested on Compaq nc6000 running Ubuntu 8.04 LTS (Hardy Heron). YMMV. I am not responsible for loss of data or damage to computers.</p>
<p>Installation of Ubuntu 8.04 LTS on Compaq nc6000 was very straight forward. After the install it automatically detected the ATI Mobility Radeon 9600 and prompted me to install restricted drivers which allows you to fully utilize the 3D potential of ATI cards. See <a href="http://picasaweb.google.com/lucidtips/RestrictedATIDrivers" target="_blank">screenshots</a>.</p>
<h3>Check if your video card can support 3D graphics</h3>
<ol>
<li>Click on <strong>System</strong>-&gt;<strong>Preferences</strong>-&gt;<strong>Appearance</strong></li>
<li>Select <strong>Visual Effects</strong> tab</li>
<li>Select <strong>Normal</strong> or <strong>Extra</strong></li>
<li>If you see &#8220;Desktop effects could not be enabled&#8221; message then your video card cannot support 3D graphics and you will not be able to use Advanced Desktop Effects.</li>
<li>Click <strong>Close</strong></li>
</ol>
<h3>Install compizconfig-settings-manager</h3>
<p>To you use Advanced Desktop Effects Settings you need to install compizconfig-settings-manager. You can install it using Synaptics Package Manager (System-&gt;Administration-&gt;Synaptics Package Manager) OR from the<strong> </strong>command line using the following command (you will be prompted for password)</p>
<pre>sudo apt-get install compizconfig-settings-manager</pre>
<p>You should now be able to use Advanced Desktop Effects. My favorite is the Rotate Cube effect which allows you to switch between workspaces.</p>
<ol>
<li>Click <strong>System</strong>-&gt;<strong>Preferences</strong>-&gt;<strong>Advanced Desktop Effects Settings</strong> (see <a href="http://picasaweb.google.com/lucidtips/EnableAdvancedDesktopEffectsOnUbuntu/photo#5231843197593604594" target="_blank">screenshot</a>)</li>
<li>Select <strong>Rotate Cube</strong> (see <a href="http://picasaweb.google.com/lucidtips/EnableAdvancedDesktopEffectsOnUbuntu/photo#5231843203865597826" target="_blank">screenshot</a>)</li>
<li>A message &#8220;Rotate Cube requires plugin Desktop Cube&#8221; will be displayed. Click <strong>Enable Desktop Cube</strong> (see <a href="http://picasaweb.google.com/lucidtips/EnableAdvancedDesktopEffectsOnUbuntu/photo#5231843202601941746" target="_blank">screenshot</a>)</li>
<li>A message &#8220;Plugin Desktop Wall provides feature largedesktop which is also provided by Desktop Cube&#8221; will be displayed. Click <strong>Disable Desktop Wall</strong> (see <a href="http://picasaweb.google.com/lucidtips/EnableAdvancedDesktopEffectsOnUbuntu/photo#5231843202891752386" target="_blank">screenshot</a>)</li>
<li>Click <strong>Close</strong></li>
</ol>
<p>To use Round Cube to  switch between workspaces by using <strong>Ctrl-Alt-Left</strong> or <strong>Ctrl-Alt-Right</strong>. To use Desktop Wall to swtich between workspaces first press <strong>Ctrl-Alt-Down</strong> and then <strong>Ctrl-Alt-Left</strong> or <strong>Ctrl-Alt-Right</strong>.</p>
<p>Another cool effect is Water Effect (see <a href="http://picasaweb.google.com/lucidtips/EnableAdvancedDesktopEffectsOnUbuntu/photo#5232558475565263778" target="_blank">screenshot</a>)</p>
<p>There are many more effects &#8230; play around with different settings and have fun <img src='http://www.lucidtips.com/wordpress/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /></p>

			<content:encoded><![CDATA[<p>On Ubuntu Synaptics package manager allows you to search and install packages. It is essentially a front end to APT (<a href="http://en.wikipedia.org/wiki/Advanced_Packaging_Tool" target="_blank">Advanced Packaging Tool</a>) and package management can be performed from the command line as well. This can be very handy if you are using SSH to connect to a remote machine and do not have the luxury of using the graphical interface.</p>
<p>apt-cache and apt-get are the commands that work with APT and help searching/installing packages.</p>
<p><span style="text-decoration: underline;"><strong>Disclaimer</strong></span>: The instructions provided in this howto make changes to your system. Please proceed with caution. I am not responsible for loss of data or damage to computers.</p>
<p>apt-cache does not make any changes to the system but does provide options to search the package metadata. Using apt-cache is very easy and the syntax to search for a package is</p>
<pre>apt-cache search &lt;searchstring&gt;</pre>
<p>For example the following command can be used for searching packages related to Java.</p>
<pre>apt-cache search java</pre>
<p>Note that it searches through the package name and description and the search result is a big list. The grep command is handy to filter the list</p>
<pre>apt-cache search java | grep sun</pre>
<p><a href="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/07/apt-cache.jpg" target="_blank"><img class="alignnone size-medium wp-image-60" title="apt-cache" src="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/07/apt-cache-300x253.jpg" alt="" width="300" height="253" /></a></p>
<p>Now that the package is identified you can see additional details about the package</p>
<pre>apt-cache show &lt;package&gt;</pre>
<p>This will show details about the package such as maintainer, version, dependencies, long description etc. For example to see details about Sun Java5 JDK the command would be</p>
<pre>apt-cache show sun-java5-jdk</pre>
<p>If you wish to install a package the command is apt-get. Since apt-get makes changes to the system you need to run it using sudo and will be prompted for password.</p>
<pre>sudo apt-get install &lt;package&gt;</pre>
<p>For example to install Sun Java5 JDK the command would be</p>
<pre>sudo apt-get install sun-java5-jdk</pre>
<p>Note that apt-get will automatically identify all the dependencies to run the package being installed.</p>
<p><a href="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/07/apt-get.jpg" target="_blank"><img class="alignnone size-medium wp-image-61" title="apt-get" src="http://www.lucidtips.com/wordpress/wp-content/uploads/2008/07/apt-get-300x253.jpg" alt="" width="300" height="253" /></a></p>
<p>Multiple packages can be installed at the same time using the syntax</p>
<pre>sudo apt-get install &lt;package 1&gt; &lt;package 2&gt; ... &lt;package n&gt;</pre>
<p>The syntax to remove a package is</p>
<pre>sudo apt-get remove &lt;package&gt;</pre>
<p>Multiple packages can be removed at the same time as well</p>
<pre>sudo apt-get remove &lt;package 1&gt; &lt;package 2&gt; ... &lt;package n&gt;</pre>
<p>apt-get can also be used to apply the latest patches to the system.</p>
<p>To update the list of packages available run the following command. This will only download the list of packages and not apply them.</p>
<pre>sudo apt-get update</pre>
<p>Now to download and apply the patches run the command</p>
<pre>sudo apt-get upgrade</pre>
<p><a href="http://www.debian.org/doc/user-manuals#apt-howto" target="_blank">APT-HOWTO manuals</a> at debian.org provide good information on APT and its features and also provides good examples.</p>
