Install gOS in Ubuntu

The Ubuntu Geek blog gives us the skinny on how to install the web-app-focused gOS operating system, star of Wal-Mart’s $200 PC, on an Ubuntu system (or most any distro ending in -buntu, for that matter). While gOS is still available as a free download/live CD, placing it on your actual hard drive gives you a chance to see if it runs a little faster and smoother than your current *buntu system, and might make a convert out of you. To see what’s worth checking out, head over to Adam’s guide to turning an old PC into a webapp monster.

Ubuntu 8.04 Alpha 4 Released : Gr8 New Apps

The Ubuntu developers are moving very quickly to bring you the absolute latest and greatest software the Open Source Community has to offer. Hardy Heron Alpha 4 is the fourth alpha release of Ubuntu 8.04, and with this new alpha release comes a whole host of excellent new features.

Features :

Xorg 7.3 : The latest Xorg is available in Hardy, Xorg 7.3, with an emphasis on better autoconfiguration with a minimal configuration file.

Linux kernel 2.6.24 : Alpha 4 includes the 2.6.24-5.8 (2.6.24-rc8-based) kernel. This brings in significant enhancements and fixes that have been merged in the last few months into the mainline kernel. Among these is the introduction of dynticks support for amd64, bringing the same power savings already available on 32-bit systems to 64-bit laptops and desktops.

PulseAudio : Alpha 4 includes [WWW] PulseAudio enabled by default. Some non-GNOME applications still need to be changed to output to pulse/esd by default and the volume control tools are still not integrated.

PolicyKit : With Alpha 4, PolicyKit integration is visible in the administrative user interfaces. PolicyKit makes it possible to run administrative applications as a normal user, and have them get a particular set of extra privileges for certain operations, which allows fine-grained control over user permissions and enhances usability, as well as eliminating the security implications of running the whole application as root.

Firefox 3 Beta 2 : The latest Firefox 3 beta is packaged in the repositories, bringing much better system integration including icon and colour theming that matches the system, as well as GTK2 form buttons and open dialog.

Transmission : The GTK version of the popular Transmission BitTorrent client comes with Alpha 4. It’s set to replace the Gnome BitTorrent downloader.

Vinagre : The new Vinagre VNC client is installed by default in Alpha 4, replacing xvnc4viewer.Vinagre allows the user to view multiple machines simultaneously, can discover VNC servers on the network via Avahi, and can keep track of recently used and favorite connections.

Brasero : The Brasero CD/DVD burning application, which will complement the CD/DVD burning functions of Nautilus and replace the Serpentine audio CD burning utility, is installed by default in Alpha 4.

World Clock Applet : Integrating the features of the intlclock applet, the GNOME panel clock in Alpha 4 can display the time and weather in multiple locations.

GVFS : Nautilus 2.21.6 in Alpha 4 uses GVFS, the virtual filesystem abstraction layer that’s set to replace the aging GnomeVFS in GNOME 2.22, as its backend. In the near future, GVFS will make it possible to fix shortcomings of Nautilus such as the inability to restore files from trash, pause and undo file operations, and make it possible to escalate user privileges for certain operations using PolicyKit for authentication. It also brings a significant performance boost to many operations.

GNOME System Monitor : The GNOME System Monitor has a revamped “Resources” tab, with Cairo graphs that scroll and scale smoothly, and brand new widgets.

Virtualization :

  • KVM is now officially maintained within the Ubuntu kernel.
  • libvirt and virt-manager have been adapted to Ubuntu. They allow for easy guest creation and basic management out of the box. Virt-manager can be used to remotely administer guests on a remote server. They also work with XEN, even though it is not officially maintained.
  • The kernel also includes the virtio modifications which should greatly improve guest I/O access.

Firewall: ufw (Uncomplicated Firewall) is a new firewall application designed to make administering a firewall easier for end-users while not getting in the way of network administrators. Currently, ufw is a command-line interface for administering host-based firewalls.

Intrusion Detection: Snort, Base, MySQL, and Apache2 On Ubuntu 7.10 (Gutsy Gibbon) (Updated)

This tutorial is based on another howto written by DevilMan, however I didn’t like the idea of manually compiling every package or the use of a GUI to get the software installed. This howto will work on a Gutsy Server or Gutsy desktop. With that said some of this howto is a direct copy from the original.In this tutorial I will describe how to install and configure Snort (an intrusion detection system (IDS)) from source, BASE (Basic Analysis and Security Engine), MySQL, and Apache2 on Ubuntu 7.10 (Gutsy Gibbon). Snort will assist you in monitoring your network and alert you about possible threats. Snort will output its log files to a MySQL database which BASE will use to display a graphical interface in a web browser.

Three Ways To Access Linux Partitions (ext2/ext3) From Windows On Dual-Boot Systems

Version 1.0
Author: Falko Timme

If you have a dual-boot Windows/Linux system, you probably know this problem: you can access files from your Windows installation while you are in Linux, but not the other way round. This tutorial shows three ways how you can access your Linux partitions (with ext2 or ext3 filesystem) from within Windows: Explore2fs, DiskInternals Linux Reader, and the Ext2 Installable File System For Windows. While the first two provide read-only access, the Ext2 Installable File System For Windows can be used for read and write operations.

I do not issue any guarantee that this will work for you!

Monitoring WordPress (And Other Database-Backed PHP Apps) With Hyperic HQ

This howto is for users and admins of PHP/MySQL web applications who are looking for a way to monitor the data from these applications. This howto is not geared specificially to monitoring the system resource usage of the web server and database, although that is one piece of the puzzle. Instead, the focus of this howto is using Hyperic HQ’s SQL Query plugin to monitor the data contained within the backing database, in this case the number of posts, comments and users from a WordPress blog deployment. Then, we will view this data in the context of system resource usage, to help admins correlate the information from the WordPress plugin we’re about to create with whatever other data they’re monitoring from that system.

This howto assumes that you are at least familiar with Hyperic HQ. For more information on how to install the HQ monitoring system, see Also, note that this was created with Hyperic HQ 3.2 Beta 4, but the process is very similar for HQ 3.1.x.

Simple Home File Server (Based On Ubuntu)

Version 1.0

Author: Xam

This tutorial explains how to turn an old PC with additional hard disks into a simple home file server. The file server is intended for home use. The home file server is accessible by Windows and Linux computers in the home network.

The existing tutorials do not describe how to add additional disks or have a complex authorization or access procedure. Freenas ( does have too many features for home users and more important it does not support the NTFS format.

This Home File Server can work with hard disks formatted in NTFS. So when you need or want to move the hard disk into a new computer, they are accessible by Windows and most Linux operating systems.The server is built with Ubuntu Server 7.10 & Samba. Do not use Ubuntu Server 5.04 LTS because this version does not support the latest SATA Controllers (in an Pentium II or III you likely want to use a PCI SATA RAID controller to attach SATA hard disks).

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

Wine 0.9.51

Wine is an Open Source implementation of the Windows API on top of X and Unix. Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, Mac OS X, and Solaris.


  • A bunch of WinHelp improvements.
  • Better Japanese font support.
  • A ton of rpcrt4 fixes.
  • Several Alsa capture fixes.
  • Improved support for screen resolution changes.
  • Lots of bug fixes.

Ubuntu Linux vs Windows Vista: The Desktop Battle

Author: Borys Musielak says

It may be a brave opinion but I predict that Ubuntu Linux and Windows Vista are going to be the two operating systems that will take over the largest chunk of the desktop OS market during the next couple of years. This comparison is based on my experience with both systems during the last couple of weeks on two different computers.

How To Build A Low Cost Linux Home Server

Superczar @ Techenclave has written an excellent article on how to build a low cost linux home server.

This is what superczar has to say about Linux Home Server.

Do I need a home server you ask?
Do any of the situations below sound familiar?

  • You have 2 or more computers at home with files fragmented between them and multiple copies of multiple files (music/movies/docs) spread all over the place?
  • You are a compulsive downloader and have accounts to multiple private trackers. Your primary beast machine runs 24X7 guzzling power and dissipating heat only to use like 0.1% of its processing capabilities while downloading
  • You have often felt the need to gain access to some of the files at your home while visiting friends/colleagues. Like, ” Oh, I wish I could show you the pics I took in the last office party…If only I had remembered to carry them in my pen-drive”
  • You are at office and someone is raving about a new album and you wish you could hear it the moment you hit home
  • you are stuck in a traffic jam and realize you forgot to start that all important DivX to mp4 conversion for a bunch of videos

If the answers to any of the above is yes , you need a home server

Turn Your PC into a Linux Home Theater PC

Extremetech has a nice article on how to turn your computer into a HTPC for free.

The term “Home Theater PC” (HTPC) is rather ambiguous. A simple file server loaded with videos and music would let you play back media from any node on your home network, but you’ll probably want a bit more than that out of your HTPC.

HTPC machines are commonly used to play and record streaming media (usually from the Internet or cable TV), host media from static sources such as DVDs and CDs, play back the hosted media on both a TV and other computers, and manipulate that media in ways that we aren’t conveniently able to when using traditional devices. That last bit encompasses automatically skipping commercials, pausing live TV, etc.

HTPCs are usually connected to TVs for video output and use IR remote controls for input. Most HTPC software goes above and beyond this call of duty by also integrating slick interfaces to programming listings, games and emulators, photo slideshows, and even web browsers.
