[125006320010] |<title>How to Install Java Runtime Environment (JRE) in Ubuntu 9.04 (Jaunty)</title>
[125006320020] |Java is an object-oriented programming language developed by Sun Microsystems in the early 1990s. Java applications are compiled to bytecode, which at runtime is either interpreted or compiled to native machine code for execution.
[125006320030] |The language itself derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities.
[125006320040] |JavaScript, a scripting language, shares a similar name and has similar syntax, but is not directly related to Java.
[125006320050] |Currently Ubuntu has the following Java packages
[125006320060] |sun-java6-bin - Contains the binaries
[125006320070] |sun-java6-demo - Contains demos and examples
[125006320080] |sun-java6-doc - Contains the documentation
[125006320090] |sun-java6-fonts - Contains the Lucida TrueType fonts from the JRE
[125006320100] |sun-java6-jdk - Contains the metapackage for the JDK
[125006320110] |sun-java6-jre - Contains the metapackage for the JRE
[125006320120] |sun-java6-plugin - Contains the plug-in for Mozilla-based browsers
[125006320130] |sun-java6-source - Contains source files for the JDK
[125006320140] |<strong>Installing the Java Runtime Environment</strong>
[125006320150] |First you need to check multiverse repository enabled or not after that open a terminal window.
[125006320160] |Since you are going to be installing the JRE and the web browser plug-in, you’ll be using the following command from a terminal
[125006320170] |sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
[125006320180] |Once it downloads the packages and begins the installation, you’ll get a screen that contains the Sun Operating System Distributor License for Java and hit Enter to continue.
[125006320190] |You’ll see a dialog that asks you if you agree with the DLJ license terms.
[125006320200] |Select Yes, and hit Enter; the JRE will finish installing.
[125006320210] |<strong>Testing Java Runtime Environment</strong>
[125006320220] |You’ll want to confirm that your system is configured properly for Sun’s JRE.
[125006320230] |This is a two-step process.
[125006320240] |First, check that the JRE is properly installed by running the following command from a terminal.
[125006320250] |<code>java -version</code>
[125006320260] |You should get similar output

[125006390010] |<title>Ubuntu Tip:Linking Music Across Operating Systems</title>
[125006390020] |Symbolic links really shine when it comes to a dual boot system.
[125006390030] |This is especially so in the case of linking your /home/Music folder in Ubuntu, to your Windows iTunes folder.
[125006390040] |Doing this means only one folder needs to be maintained and any music program you installed on Ubuntu will load your Windows music library.
[125006390050] |To do this you will need to have your Windows partition mounted.
[125006390060] |Next open up terminal and do the following.
[125006390070] |>cd /home
[125006390080] |>rm -r Music
[125006390090] |>ln -s /media/WINDOWSDRIVENAME/Users/USERNAME/Music/iTunes/iTunes\ Music/ Music
[125006390100] |Now when you install Songbird or open Rhythmbox, you will have instant access to your main music library.

[125006410010] |<title>Open Movie Editor - a simple non-linear video editor</title>
[125006410020] |Open Movie Editor is a free and open source video editing program, designed for basic movie making capabilities.
[125006410030] |It aims do be powerful enough for the amateur movie artist, yet easy to use.
[125006410040] |<strong>Install Open Movie Editor in Ubuntu</strong>
[125006410050] |sudo apt-get install openmovieeditor
[125006410060] |<strong>Using Open Movie Editor</strong>
[125006410070] |If you want to open go to Applications--->Sound &Video--->Open Movie Editor
[125006410080] |<img/>Once it opens you should see similar to the following screen

[125006410100] |<strong>Copy Video Tapes from the Camcorder</strong>
[125006410110] |If you own a DV Camcorder, and you want to transfer your recorded tapes to the computer, the recommended tool to use is dvgrab.This is command line tool.
[125006410120] |<strong>Install dvgrab in ubuntu</strong>
[125006410130] |sudo apt-get install dvgrab
[125006410140] |<strong>Using dvgrab</strong>
[125006410150] |This is simple example how to use dvgrab from command line
[125006410160] |dvgrab <code>--</code>autosplit <code>--</code>format dv2 <code>--</code>size 0 <code>--</code>opendml my_videofile-
[125006410170] |The autosplit option splits your video into a new file whenever a scene change happens.
[125006410180] |This is, whenever you paused or switched off your camera when recording your tape.
[125006410190] |This is convenient, because it organizes your file such that each file represents one continuous recording.
[125006410200] |The format dv2 option selects the avi dv2 file format for your recordings, which is not only compatible with the Open Movie Editor, but also with a number of other Video Editing Applications that run on Windows.
[125006410210] |The opendml option is necessary for video files to have sizes larger than 1 GigaByte.
[125006410220] |A word of warning though, while files larger than 2 GigaBytes work well under normal Linux Installations, it can be impossible to copy such large files to harddisks that were formatted for compatibility with older Windows Versions (FAT Filesystems).
[125006410230] |Unfortunately external USB Harddisks are often formatted like this, so be aware.
[125006410240] |The option size is set to zero, which makes the dvgrab software disable the default file size limit of 1 GigaByte.
[125006410250] |This is necessary, because DV Video Files may become rather large, and having them split into plenty of small files is not very convenient.
[125006410260] |Read the previous Paragraph to understand why the Splitting is enabled by default, it is for compatibility with certain Harddisks.
[125006420010] |<title>Step By Step Ubuntu 9.04 (Jaunty) LAMP Server Setup</title>
[125006420020] |In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go.
[125006420030] |This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications.

[125006510040] |It worked natively on Ubuntu 8.04, where it was detected as ath0. I upgraded from 8.04 to 8.10 whereby I noticed my wireless PCI card didn’t work natively anymore.
[125006510050] |Someone suggested me to upgrade from 8.10 to 9.04 Jaunty, and I did that immediately.
[125006510060] |After the system upgrade I noticed again that my wireless device was gone in Ubuntu 9.04.
[125006510070] |When I ran iwconfig I didn’t see wlan0 or ath0 anymore.
[125006510080] |Here you can see some details of my PCI card:
[125006510090] |7 root@linux $ lspci | grep Atheros 04:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
[125006510100] |Now I’ll confirm that I’m running Ubuntu 9.04 Jaunty:
[125006510110] |8 root@linux $ lsb_release -a No LSB modules are available.
[125006510120] |Distributor ID: Ubuntu Description: Ubuntu 9.04 Release: 9.04 Codename: jaunty
[125006510130] |In the beginning I only saw the following on Jaunty.
[125006510140] |Here you can see that a wireless device doesn’t show up.
[125006510150] |24 root@linux $ iwconfig lo no wireless extensions eth0 no wireless extensions pan0 no wireless extensions wmaster0 no wireless extensions.
[125006510160] |I’ve tried stuff like madwifi, ndiswrapper and previous modules like ath_pci .
[125006510170] |None of them was able to fix my problem, the wireless device was still missing.
[125006510180] |Then I’ve heard that I need the ath5k FOSS Linux Wireless driver, something that is provided by the compat-wireless package.
[125006510190] |I downloaded a compat-wireless tarball from orbit-lab.org but I was unable to get it working.
[125006510200] |While compiling I received several errors, one of these errors reported something like “You need to have mac 08211 enabled in your kernel …”.
[125006510210] |After trying different versions of the compat-wireless tarball on the Ubuntu Generic kernel I realized that it was impossible to compile this on a default Ubuntu generic kernel.
[125006510220] |So you have to compile your own kernel.
[125006510230] |While I’m writing this tutorial I see that 2.6.29.3 is the latest version of the Linux kernel.
[125006510240] |Keep in mind that this version might be old now, so is the wget link.
[125006510250] |Start a konsole/terminal and enter this as root:
[125006510260] |cd /usr/src wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.3.tar.bz2 tar xjf linux-2.6.29.3.tar.bz ln -s linux-2.6.21.3 linux cd linux make clean &&make mrproper cp /boot/config-`uname -r` ./.config
[125006510270] |You must first enable mac80211 in order to enable ath5k!
[125006510280] |Now as root, run: (You still have to be in /usr/src/linux)
[125006510290] |make menuconfig
[125006510300] |You can eventually load your alternate configuration file, but this isn’t compulsory.
[125006510310] |Now you have to commit some very important changes.
[125006510320] |Use your arrow keys to navigate:
[125006510330] |Networking ---> Wireless ---> Improved wireless configuration API M Generic IEEE 802.11 Networking Stack (mac80211) Make sure that you see the “M” like above.
[125006510340] |Now you’ve enabled mac80211.
[125006510350] |Now you can enable ath5k in the kernel configuration.
[125006510360] |Device Drivers ---> [*] Network device support ---> Wireless LAN ---> M Atheros 5xxx wireless cards support Make sure it looks like this.
[125006510370] |Now you’re finished and you simply have to select Exit.
[125006510380] |You say YES when you the following question appears.
[125006510390] |(Do you wish to save your new kernel configuration?)
[125006510400] |Ok, now you can start with compiling your kernel. make-kpkg clean fakeroot make-kpkg --initrd --append-to-version=-mykernel kernel_image kernel_header
[125006510410] |Depending on your CPU speed, this will take a certain time.
[125006510420] |When it’s all finished you have to install your new kernel.
[125006510430] |cd /usr/src dpkg -i linux-image*.deb dpkg -i linux-headers*.deb
[125006510440] |Your GRUB bootloader configuration file should be modified automatically.
[125006510450] |Make sure that your now kernel entries are visible in your /boot/grub/menu.lst file.
[125006510460] |If not, you have to insert the necessary lines by modifying your /boot/grub/menu.lst file.
[125006510470] |Reboot now, and boot in your new self-compiled kernel.
[125006510480] |Download a compat-wireless tarball from orbit-lab.org. Extract the tarball, go into the newly created map and install compat-wireless.
[125006510490] |tar jxvf compat-wireless*.tar.bz2 or tar zxvf compat-wireless*.tar.gz cd compat-wireless* make &&make install depmod -a
[125006510500] |Now you should be able to load the necessary module.
[125006510510] |modprobe ath5k
[125006510520] |And wow, a wireless device appears while you run iwconfig
[125006510530] |Check your /etc/network/interfaces file and restart the service with /etc/init.d/networking restart and it should be working.

[125006540230] |<strong>3) Remote Desktop (vnc) screen freezes when remote host is 9.04</strong>
[125006540240] |<strong>Bug Details</strong>
[125006540250] |When using the nvidia-restricted driver and compiz desktop effects the vnc server will not refresh the screen.
[125006540260] |This is being caused by the xserver not getting “damaged” by the nvidia-restricted drivers.
[125006540270] |<strong>Workaround</strong>
[125006540280] |1) Disable Compiz on the remote machine System -> Preferences -> Appearance -> Visual Effects = None

[125006540340] |<strong>Bug Details</strong>
[125006540350] |When adding a printer attached to and shared on my Windows XP box with System->Administration->Printing, New->Network Printer->Windows Printer via SAMBA, Browse - you get right up to where clicking the little gray diamonds should reveal a networked printer and Poof the dialog crashes and is gone.
[125006540360] |<strong>Workaround</strong>
[125006540370] |Used the Windows box IP address instead of Browsing for the printer.
[125006540380] |This permits you to go to the next steps and create a printer, although it won’t work yet, i.e. test page won’t print. Next click the change URI button for the printer path name and it will present another opportunity to Browse.
[125006540390] |This time it will find the Windows printer, correctly changing the path and then the test page will print and the printer is setup.
[125006540400] |<strong>5) wubi installer’s pyrun.exe says “no disk”</strong>
[125006540410] |<strong>Bug Details</strong>
[125006540420] |Wubi repeatedly complains “no disk” with “Cancel, Try again, Continue” on some systems with card readers
[125006540430] |<strong>Workaround</strong>
[125006540440] |One work-around: Use Windows’ “Safely remove hardware” to disconnect card reader and try again
[125006540450] |Another work-around: Bypass Wubi and install Ubuntu into its own partition
[125006540460] |<strong>6) mdadm software raid breaks on intrepid-jaunty upgrade</strong>
[125006540470] |<strong>Bug Details</strong>
[125006540480] |Upon upgrading from Intrepid to Jaunty, my software RAID5 array did not mount.It appears the problem may have been caused by /etc/mdadm/mdadm.conf being silently overwritten by a default config file.
[125006540490] |<strong>Workaround</strong>
[125006540500] |After executing the following in a recovery shell, the array mounts just fine.
[125006540510] |mdadm <code>--</code>examine <code>--</code>scan <code>--</code>config=mdadm.conf >>/etc/mdadm/mdadm.conf
[125006540520] |Or you can auto create a new mdadm.conf file by uninstalling mdadm, re-naming or deleting mdadm.conf, then re-booting, re-installing mdadm, and run this
[125006540530] |sudo mdadm <code>--</code>assemble <code>--</code>scan

[125006550010] |<title>Using Nginx as a Reverse Proxy to Get the Most Out of Your VPS.</title>
[125006550020] |Unravel The Music is a small startup; by that I mean we have no money, no financing, and we are owned and operated by two people.
[125006550030] |Therefore it is important that we get the most out of our server in terms of performance and cost and we have to do this without having to spend hours worrying about the server when we could be improving our design or code.
[125006550040] |First off, without good hardware it’s not going to matter how well your server is setup because you will be constantly worrying about whether your server is even up or if the datacenter is having another monthly outage.
[125006550050] |For this problem we recommend Linode.
[125006550060] |I’m sure there are plenty of other great VPS hosts out there but we have had a lot of luck with Linode and highly recommend them.
[125006550070] |This how-to is going to assume that you already have a standard LAMP stack running, if not, there are plenty of tutorials and examples on how to get a LAMP stack running.
[125006550080] |We have chosen to go with a standard Apache 2 installation using libapache2_mod_php5 over using Nginx (pronounced ‘Engine X’) with fastCGI.
[125006550090] |You may be thinking “that is preposterous, why not just use Nginx as your webserver and ditch Apache?”
[125006550100] |I hate fastCGI, I’ve never had very good luck with it and most importantly I know Apache.
[125006550110] |Also, when all Apache has to worry about is the dynamic content, in this case PHP, it is quite fast, and has a smaller memory footprint then normal Apache usage.
[125006550120] |Using Nginx as a reverse proxy is great for a few reasons.
[125006550130] |Firstly it handles static content very well.
[125006550140] |It is able to handle the requests and serve static content much faster in our tests and this has cut our page load time in about half (using YSlow with a clear cache).
[125006550150] |The memory footprint of Nginx is very small so this extra speed increase is worth every megabyte, in this case .6 megabytes of our total ram on a 540 megabyte server.
[125006550160] |Secondly, it allows for quick and easy migration of your Apache services to another server.
[125006550170] |Through the config files you are able to specify an IP of your server and a port.
[125006550180] |If your apache server is taking a pounding it wouldn’t be difficult to move it to another server and just change the proxy IP to your now remote server.
[125006550190] |Setting up Nginx is fairly straight forward.
[125006550200] |I will be showing the commands for an Ubuntu 8.04 installation but they should work for previous versions and other distributions (with a little tweaking).
[125006550210] |Install Nginx
[125006550220] |the following is essentially the config file we use for /etc/nginx/nginx.conf and is pretty similar to the default config for the installation.
[125006550230] |The only major thing I changed was adding gzip compression.
[125006550240] |I have personally set the level to 5 although it is adjustable.
[125006550250] |The higher you set this value the more CPU intensive it becomes.
[125006550260] |You are going to want to make sure that the line “include /etc/nginx/conf.d/*.conf;” is included in this config.
[125006550270] |This is where you will store the default proxy information.
[125006550280] |We will now configure the default proxy.
[125006550290] |Create the file proxy.conf in the /etc/nginx/conf.d/ folder with the following contents.
[125006550300] |The only thing you may want to change is the buffer sizes.
[125006550310] |We had to increase our proxy_buffer_size and a few others, from the default, to allow for larger cookies that were choking Nginx.
[125006550320] |With that being said you may want to decrease the buffers a bit, just do some testing.
[125006550330] |If the buffers are not working for your content Nginx will throw a 50x error.
[125006550340] |Finally, we will configure the various hosts.
[125006550350] |To save yourself some time, and possible a headache you should always keep your static assets in one folder, while subdividing them by type in containing folders.
[125006550360] |For example static->images, static->js, static->css.
[125006550370] |This will greatly simplify your Nginx installation and I’ve found your code.
[125006550380] |Now we will edit (with your favorite CLI editor) /etc/nginx/sites-available/default.
[125006550390] |Finally we need to make some quick changes to Apache and we’ll finally have everything running.
[125006550400] |Edit the file /etc/apache2/ports.conf.
[125006550410] |You’ll want to change the listen line to 127.0.0.1:8080.
[125006550420] |This will prevent apache from receiving requests from outside, but you should be blocking port 8080 anyways!
[125006550430] |The port we’ve set is 8080 but whatever you set in the Nginx configs is what you should use.
[125006550440] |Lastly, if you don’t want all your apache logs to show 127.0.0.1 for who is accessing your files or your application uses IP’s to track sessions you need to install libapache2-mod-rpaf.
[125006550450] |It is painless just issue the command below.
[125006550460] |reload or restart both Apache2 and Nginx.
[125006550470] |To see if it is working open a page on your website, if you don’t see any errors that is a good start.
[125006550480] |You can then check the logs of Apache and Nginx.
[125006550490] |Your Apache logs should only contain the php requests and your Nginx logs should contain all of your assets.
[125006550500] |Your Apache logs should also have HTTP 1.0 request when they go through the reverse proxy.
[125006550510] |If you need any support just leave a comment and we’ll try and help you.

[125006560010] |<title>Ubuntu Howto: Install projectM Audio Visualizer</title>
[125006560020] |<a>projectM</a> is an audio visualizer that is pretty spiffy.
[125006560030] |Just have it running while playing audio on your system and you will get some pretty cool effects to go with your music’s beats and rhythms.
[125006560040] |It’s by far my favorite addition to my Ubuntu 9.04 64bit HTPC.
[125006560050] |These instructions cover how to build this from source using Subversion.
[125006560060] |All italicized instuctions are commands that you can copy and paste (one line at a time), otherwise they are just that - only instructions.
[125006560070] |1. First, lets get a few packages:
[125006560080] |2. Next, add the trunk (the files you will need) to a directory in our home folder:
[125006560090] |3. Now we can start the steps to configure before we install:
[125006560100] |4. Now we are ready to compile and install:
[125006560110] |5. You should now see ProjectM-pulseaudio in your Sound menu under the Applications menu.
[125006560120] |Just start this up before or after launching your music player (I prefer Songbird).
[125006560130] |You can also start it from the CLI (command line) by typing:
[125006560140] |6. You can enter/exit fullscreen mode by pressing “f” when the projectM window is selected.
[125006560150] |Pressing “m” will bring up projectM’s menus where you can select different presets and play with settings.
[125006560160] |Pressing “l” will stop the cycling of presets, and only display the one currently being used.
[125006560170] |Have fun!

[125006570010] |<title>Screen - Manages multiple sessions on one terminal</title>
[125006570020] |This tutorial explain how to use screen and screen profiles in your ubuntu server.
[125006570030] |Screen is a program that allows you to have multiple logins on one terminal.
[125006570040] |It is useful in situations where you are telnetted into a machine or connected via a dumb terminal and want more than just one login. screen-profiles includes a set of profiles for the GNU screen window manager.
[125006570050] |These profiles are quite useful on server machines which are not running a graphical desktop.
[125006570060] |The ‘screen’ command provides a number of advanced features are not necessarily exposed in the default profile.
[125006570070] |These profiles provide features such as status bars, clocks, notifiers (reboot-required, updates-available), etc.
[125006570080] |The profile-switcher allows users to quickly switch their .screenrc to any of the available profiles.
[125006570090] |update-notifier-common provides a more efficient and standard mechanism for calculating the number of updates available in the status panel.
[125006570100] |<strong>Install screen on Ubuntu server</strong>
[125006570110] |sudo apt-get install screen screen-profiles screen-profiles-extras
[125006570120] |This will complete the installation.
[125006570130] |Note:- If you are using Jaunty all the above packages already installed in your server
[125006570140] |<strong>Using Screen</strong>
[125006570150] |From your ssh login prompt enter the following command
[125006570160] |screen
[125006570170] |or
[125006570180] |screen -S 1
[125006570190] |and select your profile option.
[125006570200] |-S sessionname - When creating a new session, this option can be used to specify a meaningful name for the session.
[125006570210] |This name identifies the session for “screen -list” and “screen -r” actions.
[125006570220] |Once it opens you should see similar to the following screen
[125006570230] |Now in this screen we are using top command
[125006570240] |If you want to open another session Ctrl a c - Creates a new screen session so that you can use more than one screen session at once.
[125006570250] |Once it opens you should see similar to the following screen

[125006600020] |UDS (Ubuntu Developer Summit) for Karmic Koala took place this year, between the 25th and 29th of May, in Barcelona, Spain.
[125006600030] |There were 270 blueprints that needed to be discussed during the summit, like the new professional look of Plymouth (an application that takes care of the graphical boot animation) for Karmic Koala, which will not become reality very soon.
[125006600040] |However, some of the ideas discussed at UDS will be implemented in the next version of the Ubuntu operating system, due for release in late October 2009.
[125006600050] |One of these was the “grub2-as-default” discussion, and Colin Watson had the pleasure to announce last night that GRUB 2 would definitely be the default boot loader in Ubuntu 9.10.
[125006600060] |Check official announcement from <a>here</a>
[125006610010] |<title>Setting up a Proftp server</title>
[125006610020] |Proftp is an opensource ftp server that is used to download files remotely using a ftp client such as filezilla or ftp from command line either with windows or linux.
[125006610030] |Proftp can be used from the command line or GUI.
[125006610040] |This tutorial will cover some of both but mainly using the GUI front-end.
[125006610050] |So lets get started with the installation and set-up of Proftp!
[125006610060] |Installation 
[125006610070] |1. sudo apt-get install proftpd gproftpd.
[125006610080] |This will install all the necessary config files for proftp along with the GUI (gui being gproftpd)
[125006610090] |2. Once install check to see if the server is running by using pgrep proftpd.
[125006610100] |If you do not see a PID than start it by typing /etc/init.d/proftpd start or status to see if again, the process is running.
[125006610110] |Configuring Server
[125006610120] |1. Once installed proftp will be under a new category of programs called system tools.
[125006610130] |Go to system tool -> GA-ADMIN PROFTP
[125006610140] |2. There are several tabs that gui provides in editing your FTP settings: they are server, users, transfers, discs, files, secuirty, and configuration
[125006610150] |Server- name your server to your liking.
[125006610160] |Use your private IP address in the address field.
[125006610170] |Issuing an ifconfig at the cmd line will bring you your private IP.By default the server is set to an idle time of 120 seconds so adjust time if you wish to.
[125006610180] |Users- this is where you will create all users that are allowed to your ftp site.
[125006610190] |You can create user accounts with annoymous access by unchecking the required password box.
[125006610200] |The users section is where you will disignate directories/drives for remote users to access as well.
[125006610210] |Transfers- Will show you files that where transfered between remote pc and server
[125006610220] |Discs- Displays directories that are avaliable to share along with how much space is currently avaliable in those directories
[125006610230] |Files- shows stastics about what was download by the user
[125006610240] |Security- Gives a log file view of who was last logged on the ftp server
[125006610250] |Configuration- If for whatever reason that your settings that you edited do not adjust you can change them here.
[125006610260] |Its easier to read by editing it here than terminal its a little cleaner and easier to see where and what you are editing
[125006610270] |Home Router settings
[125006610280] |Next, we are going to have to open up some ports on your router.
[125006610290] |Most newer routers they use port forwarding and with the older ones like my d-link router we create a new virtual server
[125006610300] |1. In your web browser go to the you gateway address which would be somthing like 192.168.0.1 or verify it by using ifconfig
[125006610310] |2. The port that you want to open is port 21 or if you feel you will be vulnerable to attacks use 2121 or something along those lines
[125006610320] |3. For the IP address of your sever it will be your private IP address
[125006610330] |4. Save settings
[125006610340] |Connecting to ftp server
[125006610350] |1. Using a client such as filezilla which is free of charge or if you are an intermediate-advance user use the command line.
[125006610360] |This is how we are going to connect to the ftp server
[125006610370] |2. Find out Your public IP address using IPchicken.com.
[125006610380] |Once there it will display your public IP
[125006610390] |3. You will use the public IP address to access you site along with a username, password, and port number.
[125006610400] |If everything is setup correctly you will be able to upload and download files.
[125006610410] |If you cannot go back and check that your settings are correct along with you private and public ip adresses
[125006620010] |<title>New Intel Graphics Drivers for Ubuntu 9.04 (Jaunty)</title>
[125006620020] |There is hope for Ubuntu users with Intel graphics.
[125006620030] |As it appears, the current 2D drivers solve most of the recent graphics problems with Intel chips, according to Ubuntu developer Bryce Harrington in a developer mailing list.
[125006620040] |Jaunty users should profit it from them as well.
[125006620050] |A nuisance to owners of Ubuntu 9.04 and Intel graphics chips has been the problems with the graphics drivers.
[125006620060] |Even though Intel manages its drivers in an exemplary open source way, 2D and 3D acceleration has fairly much dragged so far.
[125006620070] |The reason is an unhappy pairing of the current Kernel 2.6.28′s Kernel Mode Setting (KMS) with Intel’s new UXA acceleration architecture that replaces EXA and the newly added Graphics Execution Manager (GEM) in the Kernel.
[125006620080] |The solution should come in the form of the Intel 2.7.99.1 driver, as Canonical’s <a>Bryce Harrington</a> describes on the Ubuntu developer mailing list.
[125006620090] |The still somewhat unstable 2D driver should fix most of the Intel chip problems, with the stable version to appear later in Ubuntu 9.10.
[125006620100] |Harrington mentions that Jaunty users have the advantage of the Kernel 2.6.30 installation to resolve the issue.
[125006620110] |Ubuntu <a>source packets</a> are on the kernel.ubuntu.com webpage.
[125006620120] |Harrington suggests activating the UXA module in the xorg.conf file, but not <a>KMS</a>, which is deactivated by default.
[125006620130] |To activate UXA, use <em>Option AccelMethod “UXA”</em> in the <em>Section “Device”</em> in <em>/etc/x11/xorg.conf</em>.
[125006620140] |Installing the actualized 2D driver should, however, be accompanied by the stable Intel 2.7.1 driver that you can get from an <a>external Personal Package Archive (PPA)</a>.
[125006620150] |The source package is <em>xserver-xorg-video-intel</em>.
[125006620160] |Careful, though: playing with Xorg can have adverse side effects, so backing up the original files might be a good idea.

[125006630010] |<title>Ubuntu 9.10 (Karmic Koala) Alpha 2 Released</title>
[125006630020] |Ubuntu 9.10 (Karmic Koala), due for release in late October this year,The Karmic Koala Alpha 2 is the second alpha release of Ubuntu 9.10, bringing with it the earliest new features for the next version of Ubuntu.
[125006630030] |This is an alpha release.
[125006630040] |Do not install it on production machines.
[125006630050] |The final stable version will be released on October 29th, 2009.
[125006630060] |<strong>New features in Karmic</strong>
[125006630070] |Development for Karmic just recently opened and many of the new features have not yet started to appear.
[125006630080] |Currently the changes include the sync of packages from Debian Unstable or Sid has begun, a new kernel based on 2.6.30 and the latest development release of GNOME, 2.27.1.
[125006630090] |Please test and report any bugs you find:
[125006630100] |http://help.ubuntu.com/community/ReportingBugs
[125006630110] |<strong>Updated Packages</strong>
[125006630120] |As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace.
[125006630130] |Many of these packages come from an automatic sync from Debian’s Unstable branch.
[125006630140] |For a list of all packages being accepted for 9.10 Karmic Koala, please subscribe to karmic-changes:
[125006630150] |https://lists.ubuntu.com/mailman/listinfo/karmic-changes
[125006630160] |<strong>GNOME 2.27.1</strong>
[125006630170] |Ubuntu Karmic Alpha 2 includes the latest GNOME 2.27.1 development release.
[125006630180] |<strong>Linux kernel 2.6.30</strong>
[125006630190] |Alpha 2 includes the 2.6.30-5.6 kernel based on 2.6.30-rc5.
[125006630200] |The kernel will ship with Kernel Mode Setting enabled for Intel graphics (see below).
[125006630210] |LRM is deprecated in favour of DKMS packages.
[125006630220] |<strong>hal deprecation started</strong>
[125006630230] |Karmic Alpha 2′s underlying technology for power management and laptop Fn key maps was moved from “hal” (which is going to be deprecated soon) to “DeviceKit-power” and “udev-extras”.
[125006630240] |When testing Alpha 2, please pay particular attention to regressions in those two areas and report bugs.
[125006630250] |<strong>New Intel video driver architecture available for testing</strong>
[125006630260] |In later Karmic milestones the Intel video driver will most probably switch from the current “EXA” acceleration method to the new “UXA”.
[125006630270] |This will solve major performance problems of Ubuntu 9.04, but is still not as stable as EXA, which is why it is not yet enabled by default.
[125006630280] |We invite you to help testing UXA, please see the instructions and feedback page.
[125006630290] |Feedback about the new “kernel mode setting” feature is also heavily appreciated.
[125006630300] |This will reduce video mode switching flicker at booting, and dramatically speed up suspend/resume.
[125006630310] |Please see the instructions and feedback page for details.
[125006630320] |<strong>New default compiler</strong>
[125006630330] |Karmic uses GCC-4.4 as the default compiler, which in some parts is more strict than GCC-4.3, see list of changes.
[125006630340] |Please make sure to test packages on karmic or in a karmic chroot before upload.
[125006630350] |<strong>ext4 by default</strong>
[125006630360] |The new “ext4″ filesystem is used by default for new installations of Karmic; of course, other filesystems are still available via the manual partitioner.
[125006630370] |Existing filesystems will not be upgraded.
[125006630380] |If you have full backups and are confident, you can upgrade an existing ext3 filesystem to ext4 by following directions in the Ext4 Howto (note that the comments on that page at the time of writing about Ubuntu’s use of vol_id vs. blkid are out of date and are not applicable to Karmic).
[125006630390] |Maximum performance will typically only be achieved on new filesystems, not on filesystems that have been upgraded from ext3.
[125006630400] |<strong>GRUB 2 by default</strong>
[125006630410] |GRUB 2 is the default boot loader for new installations of Karmic, replacing the previous GRUB “Legacy” boot loader.
[125006630420] |Existing systems will not be upgraded to GRUB 2 at this time, as automatically reinstalling the boot loader is an inherently risky operation.
[125006630430] |If you wish to upgrade your system to GRUB 2, then see the GRUB 2 testing page for instructions.
[125006630440] |See also the upstream draft manual.
[125006630450] |Some features are still missing relative to GRUB Legacy.
[125006630460] |Notable among these are lock/password support, an equivalent of grub-reboot, and Xen handling.

[125006640010] |<title>How to Install Tuxonice in Ubuntu</title>
[125006640020] |“TuxOnIce is most easily described as the Linux equivalent of Windows’ hibernate functionality, but better.
[125006640030] |It saves the contents of memory to disk and powers down.
[125006640040] |When the computer is started up again, it reloads the contents and the user can continue from where they left off.
[125006640050] |No documents need to be reloaded or applications reopened and the process is much faster than a normal shutdown and start up.” - tuxonice.net
[125006640060] |Tuxonice is an alternative way to hibernate your machine than the standard ubuntu power manager way.
