CAElinux 2007
 | Computer Aided Engineering Linux distribution (CAElinux) Just insert the CAELinux LiveDVD in your computer to turn it into a professionnal CAE workstation: no installation is required! Based on the open-source CAE softwares Salomé & Code_Aster, you can load STEP / IGES geometry in Salomé and start partitionning and meshing your problem in just 5 minutes. |
Then you can simulate incredibly complexe physics with the ISO 9001 certified FE solver Code_Aster: non-linear thermo-mechanics, coupled fluid-structure dynamics, sismic / non-linear explicit dynamics, contacts, visco-plasticity, in other words all that you could imagine can be simulated with Code_Aster!! Then reload your results files in Salomé to post-process your data in 3D... And don't forget all these features are based on open-source / free softwares, so now you don't have to pay for excessively expensive licenses.
See Screenshots

Ad-Aware 2007 Free
 | Ad-Aware 2007 Free |
Lavasoft's Ad-Aware Free includes better detection of adware and malware, a scanning engine that goes easy on your PC's system resources, and a snazzy new interface. The updates apply to all three versions of Ad-Aware, which now go by the names Ad-Aware 2007 Free, Plus, and Pro.
In my evaluation of Ad-Aware 2007 Free, I found that the program lived up to its promise of cutting scan time on my PC; for me, this time went down from 7 minutes to 4 minutes. Harder to test was the program's new ability to seek and delete rootkits and other threats that burrow deep into your PC. For that, I take Lavasoft's word when it says earlier versions of Ad-Aware weren't equipped to handle today's threats.
Also new is the program's new interface, which is available in all three versions. Finding tools and tweaking configuration have been made much easier.
Premium Versions Deliver More
A big advantage of the Plus version, which costs $27, is the real-time protection of your system that nips adware, spyware, and malware problems in the bud before they become serious. Though real-time protection isn't new for the Plus and Pro versions, this feature may still convince you to upgrade.
Note: Existing users of Ad-Aware Plus and Pro will be able to upgrade to the new versions for free.
Conclusion In my limited testing, Ad-Aware 2007 Free is a solid post-infection tool. If you don't want to pony up the money to purchase real-time protection with Ad-Aware Plus or Pro, I recommend this free version as a utility that savvy users shouldn't be without. However, as threats become more sophisticated, the real-time protection available with the Plus and Pro versions should be a strong consideration.

Over the weekend Intel launched its long-awaited new 'Penryn' line of power-efficient microprocessors, designed to deliver better graphics and application performance as well as virtualization capabilities. The processors are the first to use high-k metal-gate transistors, which makes them faster and less leaky compared with earlier processors that have silicon gates. The processor is lead free and by next year Intel is planning to produce chips that are halogen free, making them more environmentally friendly. Penryn processors jump to higher clock rates and feature cache and design improvements that boost the processors' performance compared with earlier 65-nm processors, which should attract the interest of business workstation users and gamers looking for improved system and media performance.

Virtual CD-ROM Control Panel
Small, Free Way to Use and Mount Images (ISO files) Without Burning Them
Alcohol and Daemon Tools are excellent software packages that allow users to mount ISO files as virtual CD-ROMs. Yes, there is a way to use that ISO without burning it to a disk.
Microsoft has a free, 60kb program that does the same thing! Of course, it is not supported... and it's not as friendly as the software listed above; however, it works and it's free.

Google's Open Source Mobile Platform
As expected, today Google took the wraps off of the gPhone (as the media have for months been referring to the rumored project). Google is "leading a broad industry alliance to transform mobile phones into powerful mobile computers," and will be licensing its software to all comers on an open source basis under the Apache license. (The Wall Street Journal's Ben Worthen demonstrates a miserable grasp of what "open source" means.) Google's US partners include Nextel and Sprint, but not AT&T nor Verizon. Phones will be available in the second half of 2008 — not the spring as earlier reports had speculated. News.com's analysis warns that Google won't take over the mobile market overnight , though they quote Forrester in the opinion that Google may be one of the three biggest mobile players after several years of shakeout.

Windows XP: List of Services to Disable to Increase Speed
Constantly running in the background of XP are services--processes that help the operating system run or that provide support to applications. Many of these services launch automatically at start-up. While you need many of them, some are not required, and they can slow down your system when they run in the background.
You can disable services at start-up by using the system configuration utility, similar to the way that you halt programs from running at start-up, except that you use the Services tab instead of the Startup tab. But the system configuration utility doesn't necessarily list every service that launches on start-up. A bigger problem is that disabling services is more of shot in the dark than disabling programs. When you disable a program, you can get a sense of what the program does. But when you disable a service through the system configuration utility, there's often no way to know what it does.
A better way of disabling services at start-up is via the Services computer-management console. Run it by typing services.msc at the command prompt. The Services computer-management console includes a description of all services so that you can know ahead of time whether a particular service is one you want to turn off. It also lets you pause the service so that you can test your machine and see whether that service is needed.
After you run the console, click the Extended tab. This view will show you a description of each service in the left pane when you highlight the service. The Startup Type column shows you which services launch on start-up--any with Automatic in that field. Click that column to sort together all the services that automatically launch on start-up. Then highlight each of those services and read the descriptions.
When you find a service you want to disable, right-click it and choose Properties. In the Properties dialog box that appears, choose Manual from the Startup Type drop-down list. The service won't start automatically from now on, but you can start it manually via the console. If you want the service disabled so that it can't be run, choose Disabled. To test the results, turn off any services that you don't want to run by clicking Stop The Service in the left pane, or by right-clicking the service and choosing Stop.

If you feel these release notes could be improved in any way, you can provide your feedback directly to the beat writers. Here are several ways to do so, in order of preference:
Anaconda is the name of the Fedora installer. This section outlines issues related to Anaconda and installing Fedora 8.
Anaconda tests the integrity of installation media by default. This function works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. The Fedora Project recommends that you test all installation media before starting the installation process and before reporting any installation-related bugs. Many of the bugs reported are actually due to improperly-burned CDs or DVDs.
The mediacheck function is highly sensitive, and may report some usable discs as faulty. This result is often caused by disc writing software that does not include padding when creating discs from ISO files. To use this test, at boot time hit any key to enter the menu. Then press the Tab key, add the option mediacheck to the parameter list, and press Enter.
After you complete the mediacheck function successfully, reboot to return DMA mode to its normal state. On many systems, this results in a faster installation process from the disc. You may skip the mediacheck option when rebooting.
To perform memory testing before you install Fedora, press any key to enter the boot menu, then select Memory Test. This option runs the Memtest86 stand alone memory testing software in place of Anaconda. Memtest86 memory testing continues until you press the Esc key.
Fedora 7 supports graphical FTP and HTTP installations. However, the installer image must either fit in RAM or appear on local storage, such as Installation Disc 1. Therefore, only systems with more than 192MiB of RAM, or which boot from Installation Disc 1, can use the graphical installer. Systems with 192MiB RAM or less fall back to using the text-based installer automatically. If you prefer to use the text-based installer, type linux text at the boot: prompt.
The configuration options above causes the installer to use the same network interface as BIOS and PXE use. You can also use the following option:
This option causes the installer to use the first network device it finds that is linked to a network switch.
If you are upgrading a system with more than 15 partitions, you may need to migrate the disk to Logical Volume Management (LVM). This restriction may cause conflicts with other installed systems if they do not support LVM. Most modern Linux distributions support LVM, and drivers are available for other operating systems as well.
Confirm that each volume line in the list has a LABEL= value, as shown below:
An example of a mount by label entry is:
A matching example kernel grub line is:
This section provides notes that are specific to the supported hardware architectures of Fedora.
To list all packages with their architecture using rpm, run the following command:
You can add this to /etc/rpm/macros (for a system wide setting) or ~/.rpmmacros (for a per-user setting). It changes the default query to list the architecture:
In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
Fedora 8 requires an Intel Pentium or better processor, and is optimized for Pentium 4 and later processors.
In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.

Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
The Fedora release includes several live ISO images in addition to the traditional installation images. These ISO images are bootable, and you can burn them to media and use them to try out Fedora. They also include a feature that allows you to install the Live image content to your hard drive for persistence and higher performance.
Replace /dev/sdb1 with the partition where you want to put the image.
This is not a destructive process; any data you currently have on your USB stick is preserved.
The following sections contain information regarding software packages that have undergone significant changes for Fedora 7. For easier access, they are generally organized using the same groups that are shown in the installation system.
The yum command now retries when it detects a lock. This function is useful if a daemon is checking for updates, or if you are running yum and one of its graphical frontends simultaneously.
The yum command now understands a cost parameter in its configuration file, which is the relative cost of accessing a software repository. It is useful for weighing one software repository's packages as greater or less than any other. The cost parameter defaults to 1000.
The i810switch package has been removed. This functionality is now available through the xrandr command in the xorg-x11-server-utils package.
The evolution-exchange package replaces evolution-connector, and provides a capability under the old name.
This section covers changes and important information regarding the 2.6.23 based kernel in Fedora 8. The 2.6.23 kernel includes:
http://www.kernel.org/
To obtain a list of these patches, download the source RPM package and run the following command against it:
If you need a user friendly version of the changelog, refer to http://wiki.kernelnewbies.org/LinuxChanges. A short and full diff of the kernel is available from http://kernel.org/git. The Fedora version kernel is based on the Linus tree.
Customizations made for the Fedora version are available from http://cvs.fedoraproject.org.
Select one or more of these flavors, separated by commas and no spaces, as appropriate. Enter the root password when prompted.
This section details changes that affect Fedora graphical desktop users.
The GNOME splash screen has been disabled upstream intentionally. To enable it, use gconf-editor or the following command:
The lock screen dialog theme is not connected to the selected screensaver in this release. To enable it, use gconf-editor or the following command:
Fedora 8 does not include the KDE 4 Desktop because the currently available prerelease versions are not ready for daily use. It does include the KDE 4 Development Platform, which can be used to develop, build, and run KDE 4 applications within KDE 3 or any other desktop environment. See the Development section for more details about what is included.
To install Adobe Flash plugin follow this procedure:
This release contains Thunderbird version 2.0, which has numerous performance improvements, folder viewing enhancements, and enhanced mail notification support.
Fedora 8 provides basic support for encrypted swap partitions and non-root file systems. To use it, add entries to /etc/crypttab and reference the created devices in /etc/fstab.
The following example shows an /etc/crypttab entry for a swap partition:
This command creates an encrypted block device /dev/mapper/my_swap, which can be referenced in /etc/fstab. The next example shows an entry for a filesystem volume:
The /etc/volume_key file contains a plaintext encryption key. You can also specify none as the key file name, and the system instead asks for the encryption key during boot.
The recommended method is to use LUKS for file system volumes. If you are using LUKS you can drop the cipher= declaration in /etc/crypttab).
This section concerns electronic mail servers or mail transfer agents (MTAs).
This section covers various development tools and features.
The Eclipse SDK is known variously as "the Eclipse Platform," "the Eclipse IDE," and "Eclipse." The Eclipse SDK is the foundation for the combined release of twenty-one Eclipse projects under the Callisto combined release umbrella (http://www.eclipse.org/europa). A few of these Europa projects are included in Fedora:
Fedora also includes plugins and features that are particularly useful to FLOSS hackers, ChangeLog editing with eclipse-changelog, and Bugzilla interaction with eclipse-mylyn-bugzilla. Our CDT package, eclipse-cdt, includes a snapshot release of work to integrate with the GNU Autotools.
The latest information regarding these projects can be found at the Fedora Eclipse Project page: http://sourceware.org/eclipse/.
The 64-bit JNI libraries shipped by default on x86_64 systems in Fedora do not run on 32-bit JREs. In other words, do not try to run Fedora's x86_64 Eclipse packages on Sun's 32-bit JRE. They fail in confusing ways. Either switch to a 64-bit proprietary JRE, or install the 32-bit version of the packages, if available. To install a 32-bit version, use the following command:
Likewise, the 32-bit JNI libraries shipped by default on ppc64 systems do not run with a 64-bit JRE. To install the 64-bit version, use the following command:
The kdebase4 package also includes a beta version of the Dolphin file manager as a technology preview. Note that although Dolphin currently fails to start up when run from the KDE 3 menu, it works when run from Konsole. Other issues may exist as well. If you need a stable version of Dolphin, please install the d3lphin package, which is based on KDE 3 and can be safely installed alongside kdebase4.
These packages are designed to:
Note that kdebase4 does not include the KDE 4 Desktop package kdebase-workspace and its components such as Plasma and KWin version 4. The kdebase-workspace package is still too incomplete and unstable for daily use and would conflict with KDE 3.
This section highlights various security items from Fedora.
The java-gcj infrastructure has three key components: a GNU Java runtime (libgcj), the Eclipse Java compiler (ecj), and a set of wrappers and links (java-gcj-compat) that present the runtime and compiler to the user in a manner similar to other Java environments.
The Java software packages in this Fedora release use the java-gcj-compat environment. These packages include OpenOffice.org Base, Eclipse, and Apache Tomcat. Refer to the Java FAQ at http://www.fedoraproject.org/wiki/JavaFAQ for more information on the java-gcj-compat free Java environment in Fedora.
A simpler way to switch Java alternatives is using the sytsem-switch-java tool included in Fedora.
Refer to the latest release notes pertaining to Eclipse at http://fedoraproject.org/wiki/Docs/Beats/Devel/Tools/Eclipse.
The maven2 package in Fedora is modified to work in a fully off-line mode. With no additional properties defined (the mvn command), maven2 works exactly like upstream Maven. Users may define additional properties to facilitate off-line builds, or call mvn-jpp, a wrapper that defines the most commonly used properties for off-line building. The properties and their usage details are described in the /usr/share/doc/maven2-2.0.4/maven2-jpp-readme.html file, which comes from the maven2-manual package.
Fedora includes applications for assorted multimedia functions, including playback, recording, and editing. Additional packages are available through the Fedora Package Collection software repository. For additional information about multimedia in Fedora, refer to the Multimedia section of the Fedora Project website at http://fedoraproject.org/wiki/Multimedia.
Fedora also takes full advantage of the Advanced Linux Sound Architecture (ALSA) sound system. Many programs can play sound simultaneously, which was once difficult on Linux systems. When all multimedia software is configured to use ALSA for sound support, this limitation disappears. For more information about ALSA, visit the project website at http://www.alsa-project.org/. Users may still experience issues when multiple users log into the system. Depending upon hardware and software configurations, multiple users may not be able to use the sound hardware simultaneously.
While other MP3 options may be available for Fedora, Fluendo now offers a free MP3 plugin for GStreamer that has the necessary patent license for end users. This plugin enables MP3 support in applications that use the GStreamer framework as a backend. Fedora does not include this plugin since we prefer to support and encourage the use of patent unrestricted open formats instead. For more information about the MP3 plugin, visit Fluendo's website at http://www.fluendo.com/.
Fedora provides a selection of games that cover a variety of genres. Users can install a small package of games for GNOME (called gnome-games) and KDE (kdegames). There are also many additional games that span every major genre available in the repositories.
The Fedora Project website features a section dedicated to games that details many of the available games, including overviews and installation instructions. For more information, refer to http://fedoraproject.org/wiki/Games.
For a list of other games that are available for installation, use the Pirut graphical utility (ApplicationsAdd/Remove Software), or via the command line:
For help using yum to install the assorted game packages, refer to the guide available at:x
http://docs.fedoraproject.org/yum/
Virtualization in Fedora 8 supports both Xen and KVM virtualization platforms. The libvirt API and its corresponding tools, virt-manager and virsh, have been updated to support both KVM and Xen. Users can choose which virtualization platform to install, and use the same tools without regard to that choice.
Xen in Fedora 8 is based on version 3.1.0.
KVM in Fedora 8 is based on version 36-2.
For more information on the differences between Xen and KVM, refer to http://virt.kernelnewbies.org/TechComparison. For more information on installing and using virtualization in Fedora 8, refer to http://fedoraproject.org/wiki/Docs/Fedora8VirtQuickStart.
This section contains information related to the X Window System implementation, X.org, provided with Fedora.
The X server queries the attached monitor for supported resolution ranges, and attempts to pick the highest resolution available with the correct aspect ratio for the display. Users can set their preferred resolution in System → Preferences → Screen Resolution, and the default resolution for the system can be changed with System → Administration → Display.
If the /etc/X11/xorg.conf configuration file is not present, X also automatically detects the appropriate driver, and assumes a 105-key US keyboard layout.
We welcome feedback on the experimental intel driver. Please report success in Bugzilla, attaching the full output of lspci -vn for your machine. Given success reports, various chipsets may be switched to use the intel driver by default.
http://fedoraproject.org/wiki/Xorg/3rdPartyVideoDrivers
For more information on upgrading databases from previous releases of MySQL, refer to the MySQL website at http://dev.mysql.com/doc/refman/5.0/en/upgrade.html.
This section includes information on language support under Fedora.
In the command above, <language> is one of assamese, bengali, chinese, gujarati, hindi, japanese, kannada, korean, malayalam, marathi, oriya, punjabi, sinhala, tamil, thai, or telegu.
Users upgrading from earlier releases of Fedora are strongly recommended to install scim-bridge-gtk, which works well with 3rd party C++ applications linked against older versions of libstdc++.
To add SCIM support to input a particular language, install scim-lang-LANG, where LANG is one of assamese, bengali, chinese, dhivehi, farsi, gujarati, hindi, japanese, kannada, korean, latin, malayalam, marathi, oriya, punjabi, sinhalese, tamil, telugu, thai, or tibetan.
Through a combination of new Web tools, community growth, and better processes, translators can now contribute directly to any upstream project through one translator-oriented Web interface. Developers of projects with no existing translation community can easily reach out to Fedora's established community for translations. In turn, translators can reach out to numerous projects related to Fedora to easily contribute translations.
The following table lists the default trigger hotkeys for different languages:
Fedora provides legacy system libraries for compatibility with older software. This software is part of the Legacy Software Development group, which is not installed by default. Users who require this functionality may select this group either during installation or after the installation process is complete. To install the package group on a Fedora system, use Applications → Add/Remove Software (Pirut) or enter the following command in a terminal window:
Enter the password for the root account when prompted.

The Fedora Project is driven by the individuals that contribute to it. As a tester, developer, documenter, or translator, you can make a difference. See http://fedoraproject.org/wiki/Join for details. For information on the channels of communication for Fedora users and contributors, refer to http://fedoraproject.org/wiki/Communicate.
In addition to the website, the following mailing lists are available:
The Fedora Project also uses several IRC (Internet Relay Chat) channels. IRC is a real-time, text-based form of communication, similar to Instant Messaging. With it, you may have conversations with multiple people in an open channel, or chat with someone privately one-on-one. To talk with other Fedora Project participants via IRC, access the Freenode IRC network. Refer to the Freenode website at http://www.freenode.net/ for more information.
Fedora Project participants frequent the #fedora channel on the Freenode network, while Fedora Project developers may often be found on the #fedora-devel channel. Some of the larger projects may have their own channels as well. This information may be found on the webpage for the project, and at http://fedoraproject.org/wiki/Communicate.
In order to talk on the #fedora channel, you need to register your nickname, or nick. Instructions are given when you /join the channel.

2.1. Fedora Tour
You can find a tour filled with pictures and videos of this exciting new release at http://fedoraproject.org/wiki/Tours/Fedora8.2.2. New in Fedora
This release includes significant new versions of many key components and technologies. The following sections provide a brief overview of major changes from the last release of Fedora.2.2.1. Spins
Fedora includes several different spins, which are variations of Fedora built from a specific set of software packages. Each spin has a combination of software to meet the requirements of a specific kind of end user. In addition to a very small boot.iso image for network installation, users have the following spin choices:- A regular Fedora image for desktops, workstations, and server users. This spin provides a good upgrade path and similar environment for users of previous releases of Fedora.
- One of four Live images that can be run from a disc or USB flash device, and can be installed to hard disk as desired. See the "Live" section for more information about the Live images.
2.2.2. Features
- This test release features GNOME 2.20. GNOME now includes mail notification in the Evolution mail client, the ability to fill in PDF forms in the Evince document viewer, improved file management, a revamped Appearance control panel applet, a revised help system, and many other enhancements.
- Online Desktop provides a desktop experience designed around online services. A preview of Online Desktop is provided via BigBoard, which is a optional sidebar in GNOME.
- KDE 3.5.7 is available in the KDE Live image as well as the regular DVD. The KDE 4 (Beta) Development Environment is available in the repository.
- Xfce 4.4.1 is available as part of this release.
- NetworkManager 0.7 provides improved wireless network management support. It includes support for multiple devices and provides the capability of system-wide configuration, among many other enhancements. This transition may induce some regressions temporarily, and more testing and feedback is appreciated.
- PulseAudio is now installed and enabled by default. PulseAudio is an advanced sound server compatible with nearly all existing Linux sound systems. PulseAudio allows for hot-switching audio outputs, individual volume controls for each audio stream, networked audio, and more.
- CodecBuddy is now included, and promotes free, superior quality, open formats to end users trying to play multimedia content under patent encumbered or proprietary formats.
- Compiz Fusion, the compositing window manager that re-merges Compiz and Beryl, is installed by default. To enable Compiz Fusion in GNOME, use the System → Preferences → Desktop Effects tool. Ongoing, long term Xorg work continues to enable Compiz by default.
- A brand new graphical firewall configuration tool, system-config-firewall, replaces system-config-securitylevel.
- The completely free and open source Java environment called IcedTea is installed by default. IcedTea is derived from OpenJDK, includes a browser plugin based on GCJ, and is available for both x86 and x86_64 architectures. GCJ is still the default on PPC architecture.
- OpenOffice.org 2.3, with many new features, is available as part of Fedora 8.
- Bluetooth devices and tools now have better graphical and system integration.
- Laptop users benefit from the "quirks" feature in HAL, including better suspend/resume and multimedia keyboard support.
- There is now improved power management thanks to both a tickless kernel in x86 and x86_64 architectures, and a reduction in unnecessary processor wakeups via powertop.
- This release of Fedora has a new look and feel, called Infinity, from the Fedora Art team.
- Nodoka, a fresh new GNOME theme created specially for Fedora, is available in this release.
- A new online browser home page, http://start.fedoraproject.org, appears in this release.
- Fedora continues to improve its many proactive security features, and FORTIFY_SOURCE has now been enhanced to cover C++ in addition to C, which prevents many security exploits.
- A brand new graphical firewall configuration tool, system-config-firewall, replaces system-config-securitylevel.
- This release offers Kiosk functionality via SELinux, among many new enhancements and security policy changes.
- The glibc package in Fedora 8 now has support for passwords using SHA256 and SHA512 hashing. Before only DES and MD5 were available. The tools to create passwords have not been extended yet, but if such passwords are created in others ways, glibc will recognize and honor them.
- Secure remote management capability is now provided for Xen, KVM, and QEMU in Fedora 8 virtualization.
- Eclipse 3.3 (Europa), a new release of the acclaimed development platform, is available as part of this release.
- In this release, the performance of yum, Pirut, and Pup have been significantly improved.
- The Add/Remove Programs tool, pirut, introduces a new graphical interface for managing software repositories. Use Edit → Repositories to enable/disable any of the installed software repositories.
- Live installations are faster and require a smaller root filesystem. The file system layout has also changed somewhat. System files for the Live images are now under LiveOS/, and a new README file has been provided as a short introduction to the live image.
- Transifex provides a web-based translation interface to allow users to contribute translation work for Fedora hosted projects as well as being able to provide translations to upstream directly to any upstream project.
- Integration of unique build IDs into Fedora's software building infrastructure now provides enhanced debugging capabilities and core dumps.
- Fedora now offers easier rebranding of Fedora derivatives via a generic-logos software package. Changes in Fedora's mirror structure also make creation of derivatives easier.
- The pam_console module usage has been removed in favor of access control via HAL, which modernizes the desktop.
- Fedora 8 features a 2.6.23 based kernel.

5. Installation Notes
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
| | Fedora Installation Guide |
|---|---|
| To learn how to install Fedora, refer to http://docs.fedoraproject.org/install-guide/. |
| | Installation issues not covered in these release notes |
|---|---|
| If you encounter a problem or have a question during installation that is not covered in these relese notes, refer to http://fedoraproject.org/wiki/FAQ and http://fedoraproject.org/wiki/Bugs/Common. |
| | Downloading Large Files |
|---|---|
| If you intend to download the Fedora DVD ISO image, keep in mind that not all file downloading tools can accommodate files larger than 2 GiB in size. Tools without this limitation include wget 1.9.1-16 and above, curl, and ncftpget. BitTorrent is another method for downloading large files. For information about obtaining and using the torrent file, refer to http://torrent.fedoraproject.org/. |
The mediacheck function is highly sensitive, and may report some usable discs as faulty. This result is often caused by disc writing software that does not include padding when creating discs from ISO files. To use this test, at boot time hit any key to enter the menu. Then press the Tab key, add the option mediacheck to the parameter list, and press Enter.
After you complete the mediacheck function successfully, reboot to return DMA mode to its normal state. On many systems, this results in a faster installation process from the disc. You may skip the mediacheck option when rebooting.
| | BitTorrent Automatically Verifies File Integrity |
|---|---|
| If you use BitTorrent, any files you download are automatically validated. If your file completes downloading, you do not need to check it. Once you burn your CD or DVD, however, you should still use mediacheck to test the integrity of the media. |
| | Memtest86 Availability |
|---|---|
| You must boot from Installation Disc 1, the DVD, or a rescue CD in order to use this feature. |
5.1. Changes in Anaconda
- Improved Live images support
- Ability to install from Live image running from RAM or USB stick
- Improved IEEE-1394 (Firewire) support
- Use of /dev/hdX is deprecated on i386 and x86_64 for IDE drives, and has changed to /dev/sdX except on PPC. See note about the importance of labeling devices for upgrades from FC6, and partition limitations.
5.2. Installation Related Issues
5.2.1. IDE RAID
Not all IDE RAID controllers are supported. If your RAID controller is not yet supported by dmraid, you may combine drives into RAID arrays by configuring Linux software RAID. For supported controllers, configure the RAID functions in the computer BIOS.5.2.2. Multiple NICs and PXE Installation
Some servers with multiple network interfaces may not assign eth0 to the first network interface as BIOS knows it, which can cause the installer to try using a different network interface than was used by PXE. To change this behavior, use the following in pxelinux.cfg/* config files:IPAPPEND 2 APPEND ksdevice=bootif
The configuration options above causes the installer to use the same network interface as BIOS and PXE use. You can also use the following option:
ksdevice=link
This option causes the installer to use the first network device it finds that is linked to a network switch.
5.2.3. HP ProLiant DL360 with Smart Array
If you have difficulties with this installation not detecting the Smart Array card, try entering linux isa on the installer prompt. This lets you manually select the card.5.3. Upgrade Related Issues
Refer to http://fedoraproject.org/wiki/DistributionUpgrades for detailed recommended procedures for upgrading Fedora.5.3.1. SCSI driver partition limits
Whereas older IDE drivers supported up to 63 partitions per device, SCSI devices are limited to 15 partitions per device. Anaconda uses the new libata driver in the same fashion as the rest of Fedora, so it is unable to detect more than 15 partitions on an IDE disk during the installation or upgrade process.If you are upgrading a system with more than 15 partitions, you may need to migrate the disk to Logical Volume Management (LVM). This restriction may cause conflicts with other installed systems if they do not support LVM. Most modern Linux distributions support LVM, and drivers are available for other operating systems as well.
5.3.2. Disk partitions must be labeled
A change in the way that the linux kernel handles storage devices means that device names like /dev/hdX or /dev/sdX may differ from the values used in earlier releases. Anaconda solves this problem by relying on partition labels. If these labels are not present, then Anaconda presents a warning indicating that partitions need to be labelled and that the upgrade can not proceed. Systems that use Logical Volume Management (LVM) and the device mapper usually do not require relabeling.5.3.2.1. To check disk partition labels
To view partition labels, boot the existing Fedora installation, and enter the following at a terminal prompt:/sbin/blkid
Confirm that each volume line in the list has a LABEL= value, as shown below:
/dev/hdd1: LABEL="/boot" UUID="ec6a9d6c-6f05-487e-a8bd-a2594b854406" SEC_TYPE="ext2" TYPE="ext3"
5.3.2.2. Update the file system mount entries
If any filesystem labels were added or modified, then the device entries in /etc/fstab must be adjusted to match:su -c 'cp /etc/fstab /etc/fstab.orig' su -c 'gedit /etc/fstab'
An example of a mount by label entry is:
LABEL=f7-slash / ext3 defaults 1 1
5.3.2.3. Update the grub.conf kernel root entry
If the label for the / (root) filesystem was modified, the kernel boot parameter in the grub configuration file must also be modified:su -c 'gedit /boot/grub/grub.conf'
A matching example kernel grub line is:
kernel /vmlinuz-2.6.20-1.2948.fc6 ro root=LABEL=f7-slash rhgb quiet
5.3.2.4. Test changes made to labels
If partition labels were adjusted, or the /etc/fstab file modified, then boot the existing Fedora installation to confirm that all partitions still mount normally and login is successful. When complete, reboot with the installation media to start the installer and begin the upgrade.5.3.3. Upgrades versus fresh installations
In general, fresh installations are recommended over upgrades, particularly for systems that include software from third-party repositories. Third-party packages remaining from a previous installation may not work as expected on an upgraded Fedora system. If you decide to perform an upgrade anyway, the following information may be helpful:- Before you upgrade, back up the system completely. In particular, preserve /etc, /home, and possibly /opt and /usr/local if customized packages are installed there. You may wish to use a multi-boot approach with a "clone" of the old installation on alternate partition(s) as a fallback. In that case, create alternate boot media, such as a GRUB boot floppy.
| | System Configuration Backups |
|---|---|
| Backups of configurations in /etc are also useful in reconstructing system settings after a fresh installation. |
- After you complete the upgrade, run the following command:
rpm -qa --last > RPMS_by_Install_Time.txt
Inspect the end of the output for packages that pre-date the upgrade. Remove or upgrade those packages from third-party repositories, or otherwise deal with them as necessary. Some previously installed packages may no longer be available in any configured repository. To list all these packages, use the following command:
su -c 'yum list extras'
6. Architecture Specific Notes
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
6.1. RPM multiarch support on 64-bit platforms (x86_64, ppc64)
RPM supports parallel installation of multiple architectures of the same package. A default package listing such as rpm -qa might appear to include duplicate packages, since the architecture is not displayed. Instead, use the repoquery command, part of the yum-utils package, which displays architecture by default. To install yum-utils, run the following command:su -c 'yum install yum-utils'
To list all packages with their architecture using rpm, run the following command:
rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n" You can add this to /etc/rpm/macros (for a system wide setting) or ~/.rpmmacros (for a per-user setting). It changes the default query to list the architecture:
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch} 6.2. PPC Specifics for Fedora
This section covers specific information about Fedora and the PPC hardware platform.6.2.1. Hardware Requirements for PPC
6.2.1.1. Processor and memory
- Minimum CPU: PowerPC G3 / POWER3
- Fedora 8 supports only the "New World" generation of Apple Power Macintosh, shipped from circa 1999 onward.
- Fedora 8 also supports IBM pSeries, IBM iSeries, IBM RS/6000, Genesi Pegasos II, and IBM Cell Broadband Engine machines.
- Fedora 8 includes new hardware support for Genesi Efika, and for the Sony PlayStation 3.
- Recommended for text-mode: 233 MHz G3 or better, 128MiB RAM.
- Recommended for graphical: 400 MHz G3 or better, 256MiB RAM.
6.2.1.2. Hard disk space
The disk space requirements listed below represent the disk space taken up by Fedora 8 after installation is complete. However, additional disk space is required during installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img (on Installation Disc 1) plus the size of the files in /var/lib/rpm on the installed system.In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
6.2.2. 4 KiB Pages on 64-bit machines
After a brief experiment with 64KiB pages in Fedora Core 6, the PowerPC64 kernel has now been switched back to 4KiB pages. The installer should reformat any swap partitions automatically during an upgrade.6.2.3. The Apple keyboard
The Option key on Apple systems is equivalent to the Alt key on the PC. Where documentation and the installer refer to the Alt key, use the Option key. For some key combinations you may need to use the Option key in conjunction with the Fn key, such as Option+Fn+F3 to switch to virtual terminal tty3.6.2.4. PPC installation notes
Fedora Installation Disc 1 is bootable on supported hardware. In addition, a bootable CD image appears in the images/ directory of this disc. These images behave differently according to your system hardware:- On most machines, the bootloader automatically boots the appropriate 32-bit or 64-bit installer from the install disc. The default gnome-power-manager package includes power management support, including sleep and backlight level management. Users with more complex requirements can use the apmud package. To install apmud after installation, use the following command:
su -c 'yum install apmud'
- 64-bit IBM pSeries (POWER4/POWER5), current iSeries models. After using OpenFirmware to boot the CD, the bootloader, yaboot, automatically boots the 64-bit installer.
- IBM "Legacy" iSeries (POWER4). So-called "Legacy" iSeries models, which do not use OpenFirmware, require use of the boot image located in the images/iSeries directory of the installation tree.
- 32-bit CHRP (IBM RS/6000 and others). After using OpenFirmware to boot the CD, select the linux32 boot image at the boot: prompt to start the 32-bit installer. Otherwise, the 64-bit installer starts and fails.
- Genesi Pegasos II. At the time of writing, firmware with full support for ISO9660 file systems has not yet been released for the Pegasos. You can use the network boot image, however. At the OpenFirmware prompt, enter the following command:
boot cd: /images/netboot/ppc32.img
You must also configure OpenFirmware on the Pegasos manually to make the installed Fedora system bootable. To do this, set the boot-device and boot-file environment variables appropriately.
- Genesi Efika. At the time of writing, the firmware of the Efika has bugs which prevent correct operation of the yaboot bootloader. An updated firmware should be available by April 2007, in advance of the release of Fedora 8. With a fixed firmware, installation on Efika should be the same as on Pegasos II.
- Sony PlayStation 3. For installation on PlayStation 3, first update to firmware 1.60 or later. The "Other OS" boot loader must be installed into the flash, following the instructions at http://www.playstation.com/ps3-openplatform/manual.html. A suitable boot loader image ia located on the Fedora 8 install media. Once the boot loader is installed, the PlayStation 3 should boot from the Fedora install media. Select the linux64 from the graphical boot menu. For more information on Fedora and the PlayStation3 or Fedora on PowerPC in general, join the Fedora-PPC mailing list or the #fedora-ppc channel on FreeNode.
- Network booting. Combined images containing the installer kernel and ramdisk are located in the images/netboot/ directory of the installation tree. They are intended for network booting with TFTP, but can be used in many ways.
The yaboot loader supports TFTP booting for IBM pSeries and Apple Macintosh. The Fedora Project encourages the use of yaboot over the netboot images.
6.3. x86 Specifics for Fedora
This section covers specific information about Fedora and the x86 hardware platform.6.3.1. Hardware requirements for x86
In order to use specific features of Fedora 8 during or after installation, you may need to know details of other hardware components such as video and network cards.6.3.1.1. Processor and memory
The following CPU specifications are stated in terms of Intel processors. Other processors, such as those from AMD, Cyrix, and VIA that are compatible with and equivalent to the following Intel processors, may also be used with Fedora.Fedora 8 requires an Intel Pentium or better processor, and is optimized for Pentium 4 and later processors.
- Recommended for text-mode: 200 MHz Pentium-class or better
- Recommended for graphical: 400 MHz Pentium II or better
- Minimum RAM for text-mode: 128MiB
- Minimum RAM for graphical: 192MiB
- Recommended RAM for graphical: 256MiB
6.3.1.2. Hard disk space
The disk space requirements listed below represent the disk space taken up by Fedora 8 after the installation is complete. However, additional disk space is required during the installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img on Installation Disc 1 plus the size of the files in /var/lib/rpm on the installed system.In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
6.4. x86_64 Specifics for Fedora
This section covers specific information about Fedora and the x86_64 hardware platform.6.4.1. Hardware requirements for x86_64
In order to use specific features of Fedora 8 during or after installation, you may need to know details of other hardware components such as video and network cards.6.4.1.1. Memory requirements for x86_64
- Minimum RAM for text-mode: 256MiB
- Minimum RAM for graphical: 384MiB
- Recommended RAM for graphical: 512MiB
6.4.1.2. Hard disk space requirements for x86_64
The disk space requirements listed below represent the disk space taken up by Fedora 8 after the installation is complete. However, additional disk space is required during the installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img on Installation Disc 1 plus the size of the files in /var/lib/rpm on the installed system.In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
7. Fedora Live Images
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
7.1. Available Images
There are four Live images available for Fedora 8.- Fedora Live (i686, x86_64, ppc). This image includes the GNOME desktop environment, integrates all supported Fedora locales, and features a basic set of productivity applications. Only the i686 version fits on a CD. The x86_64 version has the same feature set and includes multilib packages.
- Fedora KDE Live (i686, x86_64). This image includes the KDE desktop environment, with full support for English language only. Only the i686 version fits on a CD. The x86_64 version has the same feature set and includes multilib packages.
- Fedora Developer Live (i686). This Live image is designed for software developers, and features the GNOME desktop environment. The toolkit includes the Eclipse integrated development environment, API documentation, and a variety of debugging and profiling utilities.
- Fedora Electronic Lab (FEL) Live (i686). This Live image is designed for engineers working on electronics, and includes a toolkit for electronic component design and simulation. The image fits on a CD.
7.2. Usage Information
To boot from the Live image, insert it into your computer and restart. To log in and use the desktop environment, enter the username fedora. Hit Enter at the password prompt, since there is no password on this account. The Live images do not automatically login so users can select a preferred language. After logging in, if you wish to install the contents of the live image to your hard drive, click on the Install to Hard Drive icon on the desktop.| | No i586 Support |
|---|---|
| The i686 Live images will not boot on an i586 machine. |
7.3. Text Mode Installation
You can do a text mode installation of the Live images using the liveinst command in the console.7.4. USB Booting
Another way to use these Live images is to put them on a USB stick. To do this, install the livecd-tools package from the development repository. Then, run the livecd-iso-to-disk script:/usr/bin/livecd-iso-to-disk /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition where you want to put the image.
This is not a destructive process; any data you currently have on your USB stick is preserved.
7.5. Differences From a Regular Fedora Install
The following items are different from a normal Fedora install with the live images.- Live images provide a subset of packages available in the regular DVD image. Both connect to the same repository that has all the packages.
- SSH is disabled by default and NetworkManager is enabled by default in the Live images. SSH is disabled because the default username in the Live images does not have any password. Installation to hard disk prompts for creating a new user name and password however. NetworkManager is enabled by default since Live images target desktop users.
- Live image installations do not allow any package selection or upgrade capability since they copy entire the filesystem from media to hard disk or USB disks. After the installation is complete and rebooted, packages can be added and removed as desired with yum or the other software management tools.
- Live images do not work on i586 architecture.
8. Package Notes
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
8.1. Yum Changes
The installonlyn plugin functionality has been folded into the core yum package. The installonlypkgs and installonly_limit options are used by default to limit the system to retain only two kernel packages. You can adjust the package set or the number of packages, or disable the option entirely to match your preferences. More details is available in the man page for yum.conf.The yum command now retries when it detects a lock. This function is useful if a daemon is checking for updates, or if you are running yum and one of its graphical frontends simultaneously.
The yum command now understands a cost parameter in its configuration file, which is the relative cost of accessing a software repository. It is useful for weighing one software repository's packages as greater or less than any other. The cost parameter defaults to 1000.
8.2. Utility Packages
The cryptsetup-luks package has been renamed to cryptsetup.The i810switch package has been removed. This functionality is now available through the xrandr command in the xorg-x11-server-utils package.
The evolution-exchange package replaces evolution-connector, and provides a capability under the old name.
9. Linux Kernel
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
- Tickless support for x86 64-bit systems (32-bit was added previously), which greatly improves power management.
- Some elements of the realtime kernel project.
- The kernel spec file is now named kernel.spec rather than kernel-2.6.spec.
- The kernel spec file has new macros that ease the kernel building process. Refer to http://fedoraproject.org/wiki/Docs/CustomKernel for further information.
- The kernel in Fedora 8 no longer loads modules by default for ISA sound cards. Load the module by hand using the command modprobe module-name, or put an entry in /etc/modprobe.conf. For example, for the Creative SoundBlaster AWE64, add the following entry:
install snd-sbawe
9.1. Version
Fedora may include additional patches to the kernel for improvements, bug fixes, or additional features. For this reason, the Fedora kernel may not be line-for-line equivalent to the so-called vanilla kernel from the kernel.org web site:http://www.kernel.org/
To obtain a list of these patches, download the source RPM package and run the following command against it:
rpm -qpl kernel-<version>.src.rpm
9.2. Changelog
To retrieve a log of changes to the package, run the following command:rpm -q --changelog kernel-<version>
If you need a user friendly version of the changelog, refer to http://wiki.kernelnewbies.org/LinuxChanges. A short and full diff of the kernel is available from http://kernel.org/git. The Fedora version kernel is based on the Linus tree.
Customizations made for the Fedora version are available from http://cvs.fedoraproject.org.
9.3. Kernel Flavors
Fedora 8 includes the following kernel builds:- Native kernel, for use in most systems. Configured sources are available in the kernel-devel package.
- The kernel-PAE, for use in 32-bit x86 systems with more than 4GB of RAM, or with CPUs that have an NX (No eXecute) feature. This kernel support both uniprocessor and multi-processor systems. Configured sources are available in the kernel-PAE-devel package.
- Virtualization kernel for use with the Xen emulator package. Configured sources are available in the kernel-xen-devel package.
- The kdump kernel for use with kexec/kdump capabilities. Configured sources are available in the kernel-kdump-devel package.
su -c 'yum install kernel{,-PAE,-xen,-kdump}-devel' Select one or more of these flavors, separated by commas and no spaces, as appropriate. Enter the root password when prompted.
| | 32bit Kernel Includes Kdump |
|---|---|
| The 32bit kernel is now relocatable, so kdump functionality is included. 64bit still requires installation of the -kdump kernel. |
| | Default Kernel Provides SMP |
|---|---|
| There is no separate SMP kernel available for Fedora on i386, x86_64, and ppc64. Multiprocessor support is provided by the native kernel. |
| | PowerPC Kernel Support |
|---|---|
| There is no support for Xen or kdump for the PowerPC architecture in Fedora. 32-bit PowerPC does still have a separate SMP kernel. |
9.4. Reporting Bugs
Refer to http://kernel.org/pub/linux/docs/lkml/reporting-bugs.html for information on reporting bugs in the Linux kernel. You may also use http://bugzilla.redhat.com for reporting bugs that are specific to Fedora.9.5. Preparing for Kernel Development
Fedora 8 does not include the kernel-source package provided by older versions since only the kernel-devel package is required now to build external modules. Configured sources are available, as described Section 9.3, “Kernel Flavors”.| | Custom Kernel Building |

10.1. GNOME
This release features GNOME 2.20.The GNOME splash screen has been disabled upstream intentionally. To enable it, use gconf-editor or the following command:
gconftool-2 --set /apps/gnome-session/options/show_splash_screen --type bool true
The lock screen dialog theme is not connected to the selected screensaver in this release. To enable it, use gconf-editor or the following command:
gconftool-2 --set --type string /apps/gnome-screensaver/lock_dialog_theme "system"
10.2. KDE
This release features KDE 3.5.6.Fedora 8 does not include the KDE 4 Desktop because the currently available prerelease versions are not ready for daily use. It does include the KDE 4 Development Platform, which can be used to develop, build, and run KDE 4 applications within KDE 3 or any other desktop environment. See the Development section for more details about what is included.
10.3. Web Browsers
This release of Fedora includes version 2.0 of the popular Firefox web browser. Refer to http://firefox.com/ for more information about Firefox.10.3.1. Enabling Flash Plugin
Fedora includes an experimental free and open source implementation of Flash called gnash. We encourage you to experiment with gnash before seeking out Adobe's proprietary Flash plugin software.To install Adobe Flash plugin follow this procedure:
- Visit Adobe's download site.
- Choose option 3, Yum repository.
- Follow onscreen prompts to install the package.
- Launch Applications → Add/Remove Software.
- Choose the Search tab and enter flash-plugin.
- Select the checkbox to install the package.
- Close all Firefox windows, and then launch Firefox again.
- Type about:plugins in the URL bar to ensure the plugin is loaded.
- Create the 32bit mozilla plugin directory using this command:
su -c 'mkdir -p /usr/lib/mozilla/plugins'
- Install the nspluginwrapper.i386, nspluginwrapper.x86_64, and pulseaudio-libs.i386 packages:
su -c "yum -y install nspluginwrapper.{i386,x86_64} pulseaudio-libs.i386" - Install flash-plugin as shown above.
- Run mozilla-plugin-config to register the flash plugin:
su -c 'mozilla-plugin-config -i -g -v'
- Close all Firefox windows, and then relaunch Firefox.
- Type about:plugins in the URL bar to ensure the plugin is loaded.
10.4. Mail Clients
The mail-notification package has been split. The Evolution plugin is now in a separate package called mail-notification-evolution-plugin. When you update the mail-notification package, the plugin is added automatically.This release contains Thunderbird version 2.0, which has numerous performance improvements, folder viewing enhancements, and enhanced mail notification support.
10.5. Liberation Fonts
This release of Fedora includes a set of fonts called "Liberation." These fonts are metric equivalents for well-known proprietary fonts prevalent on the Internet. With these fonts, users will find better cross-platform viewing and printing support for a variety of documents. Future versions of these fonts will be fully hinted.11. File Systems
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
| | Encrypted FS Support Unavailable During Install |
|---|---|
| Enable file system encryption after installation. Anaconda does not have support for creating encrypted block devices. |
my_swap /dev/sdb1 /dev/urandom swap,cipher=aes-cbc-essiv:sha256
This command creates an encrypted block device /dev/mapper/my_swap, which can be referenced in /etc/fstab. The next example shows an entry for a filesystem volume:
my_volume /dev/sda5 /etc/volume_key cipher=aes-cbc-essiv:sha256
The /etc/volume_key file contains a plaintext encryption key. You can also specify none as the key file name, and the system instead asks for the encryption key during boot.
The recommended method is to use LUKS for file system volumes. If you are using LUKS you can drop the cipher= declaration in /etc/crypttab).
- Create the encrypted volume using cryptsetup luksFormat.
- Add the necessary entry to /etc/crypttab.
- Set up the volume manually using cryptsetup luksOpen or reboot.
- Create a filesystem on the encrypted volume.
- Set up an entry in /etc/fstab.
12. Mail Servers
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
12.1. Sendmail
By default, the Sendmail mail transport agent (MTA) does not accept network connections from any host other than the local computer. To configure Sendmail as a server for other clients, edit /etc/mail/sendmail.mc and change the DAEMON_OPTIONS line to also listen on network devices, or comment out this option entirely using the dnl comment delimiter. Then install the sendmail-cf package and regenerate /etc/mail/sendmail.cf by running the following commands:su -c 'yum install sendmail-cf' su -c 'make -C /etc/mail'
13. Development
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
13.1. Tools
13.1.1. GCC Compiler Collection
This release of Fedora has been built with GCC 4.1.2, which is included with the distribution.13.1.1.1. Code Generation
Starting with gcc-4.1.2-25 and glibc-2.6.90-14, the -D_FORTIFY_SOURCE=2 option protects not only C code, but also C++. There have been several security issues already which would have been unexploitable if this checking was in place earlier. Refer to this announcement for more details.13.1.2. Eclipse
This release of Fedora includes Fedora Eclipse, based on the Eclipse SDK version 3.3.0. You can read the "New and Noteworthy" page for the 3.3.x series of releases can be accessed at http://download.eclipse.org/eclipse/downloads/drops/R-3.3-2007-06251500/whatsnew/eclipse-news.html. Release notes specific to 3.3.0 are available at http://www.eclipse.org/eclipse/development/readme_eclipse_3.3.html.The Eclipse SDK is known variously as "the Eclipse Platform," "the Eclipse IDE," and "Eclipse." The Eclipse SDK is the foundation for the combined release of twenty-one Eclipse projects under the Callisto combined release umbrella (http://www.eclipse.org/europa). A few of these Europa projects are included in Fedora:
- CDT (http://www.eclipse.org/cdt, for C/C++ development;
- GEF (http://www.eclipse.org/gef), the Graphical Editing Framework; and
- Mylyn (http://www.eclipse.org/mylyn), a task-focused UI for Eclipse, along with task connectors for Bugzilla and Trac.
- Subclipse (http://subclipse.tigris.org/), for integrating Subversion version control;
- PyDev (http://pydev.sf.net), for developing in Python; and
- PHPeclipse (http://www.phpeclipse.de/), for developing in PHP.
Fedora also includes plugins and features that are particularly useful to FLOSS hackers, ChangeLog editing with eclipse-changelog, and Bugzilla interaction with eclipse-mylyn-bugzilla. Our CDT package, eclipse-cdt, includes a snapshot release of work to integrate with the GNU Autotools.
The latest information regarding these projects can be found at the Fedora Eclipse Project page: http://sourceware.org/eclipse/.
13.1.2.1. Non-packaged Plugins/Features
Fedora Eclipse allows non-root users to make use of the Update Manager functionality for installing non-packaged plugins and features. Such plugins are installed in the user's home directory under the .eclipse directory. Please note, however, that these plugins do not have associated GCJ-compiled bits and may therefore run slower than expected.13.1.2.2. Alternative Java Runtime Environments
The Fedora free JREs do not satisfy every user, so Fedora does allow the installation of alternative JREs. A caveat exists, however, for installing proprietary JREs on 64-bit machines.The 64-bit JNI libraries shipped by default on x86_64 systems in Fedora do not run on 32-bit JREs. In other words, do not try to run Fedora's x86_64 Eclipse packages on Sun's 32-bit JRE. They fail in confusing ways. Either switch to a 64-bit proprietary JRE, or install the 32-bit version of the packages, if available. To install a 32-bit version, use the following command:
yum install <package_name>.i386
Likewise, the 32-bit JNI libraries shipped by default on ppc64 systems do not run with a 64-bit JRE. To install the 64-bit version, use the following command:
yum install <package_name>.ppc64
13.2. KDE 4 Development Platform
Fedora 8 includes KDE 4.0 (beta) development libraries. The following new packages are provided:- kdelibs4: KDE 4 libraries
- kdepimlibs: KDE 4 PIM libraries
- kdebase4: KDE 4 core runtime files
The kdebase4 package also includes a beta version of the Dolphin file manager as a technology preview. Note that although Dolphin currently fails to start up when run from the KDE 3 menu, it works when run from Konsole. Other issues may exist as well. If you need a stable version of Dolphin, please install the d3lphin package, which is based on KDE 3 and can be safely installed alongside kdebase4.
These packages are designed to:
- comply with the Filesystem Hierarchy Standard (FHS), and
- be completely safe to install in parallel with KDE 3, including the -devel packages.
- The library symlinks are installed to /usr/lib/kde4/devel or /usr/lib64/kde4/devel, depending on system architecture.
- The kconfig_compiler and makekdewidgets tools have been renamed kconfig_compiler4 and makekdewidgets4, respectively.
Note that kdebase4 does not include the KDE 4 Desktop package kdebase-workspace and its components such as Plasma and KWin version 4. The kdebase-workspace package is still too incomplete and unstable for daily use and would conflict with KDE 3.
14. Security
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
14.1. Security Enhancements
- Fedora continues to improve its many proactive security features, and FORTIFY_SOURCE has now been enhanced to cover C++ in addition to C, which prevents many security exploits.
- A brand new graphical firewall configuration tool, system-config-firewall, replaces system-config-securitylevel.
- This release offers Kiosk functionality via SELinux, among many new enhancements and security policy changes.
- The glibc package in Fedora 8 now has support for passwords using SHA256 and SHA512 hashing. Before only DES and MD5 were available. The tools to create passwords have not been extended yet, but if such passwords are created in others ways, glibc will recognize and honor them.
- Secure remote management capability is now provided for Xen, KVM, and QEMU in Fedora 8 virtualization.
14.2. General Information
A general introduction to the many proactive security features in Fedora, current status, and policies is available at http://fedoraproject.org/wiki/Security.14.2.1. SELinux
The SELinux project pages have troubleshooting tips, explanations, and pointers to documentation and references. Some useful links include the following:- New SELinux project pages: http://fedoraproject.org/wiki/SELinux
- Troubleshooting tips: http://fedoraproject.org/wiki/SELinux/Troubleshooting
- Frequently Asked Questions: http://docs.fedoraproject.org/selinux-faq/
- Listing of SELinux commands: http://fedoraproject.org/wiki/SELinux/Commands
- Details of confined domains: http://fedoraproject.org/wiki/SELinux/Domains
15. IcedTea and java-gcj-compat
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
15.1. IcedTea
This release of Fedora includes the IcedTea environment. IcedTea is a build harness for Sun's OpenJDK code that replaces encumbered parts of OpenJDK with Free Software replacements. IcedTea provides a more complete, compatible environment than GCJ, including support for building and running bytecode up to the 1.6 level. Users of IcedTea should be aware of a few caveats:- There is no ppc or ppc64 support. Users of ppc and ppc64 systems should continue to use GCJ.
- There is no support for the Java sound APIs.
- There are a few missing cryptographic algorithms.
15.2. Handling Java Applets
The Fedora IcedTea packages also include an adaptation of gcjwebplugin that runs untrusted applets safely in a web browser. The plugin is packaged as java-1.7.0-icedtea-plugin.- The gcjwebplugin adaptation has no support for the bytecode-to-Javascript bridge, so applets that rely on this bridge will not work.
- The gcjwebplugin adaptation has no support for signed applets. Signed applets will run in untrusted mode.
- The gcjwebplugin security policy may be overly restrictive. To enable restricted applets, run firefox -g in a terminal window to see what is being restricted, then grant the restricted permission in /usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0/jre/lib/security/java.policy.
15.3. java-gcj-compat
This release of Fedora includes java-gcj-compat. The java-gcj-compat collection includes a tool suite and execution environment that is capable of building and running many useful programs that are written in the Java programming language.The java-gcj infrastructure has three key components: a GNU Java runtime (libgcj), the Eclipse Java compiler (ecj), and a set of wrappers and links (java-gcj-compat) that present the runtime and compiler to the user in a manner similar to other Java environments.
The Java software packages in this Fedora release use the java-gcj-compat environment. These packages include OpenOffice.org Base, Eclipse, and Apache Tomcat. Refer to the Java FAQ at http://www.fedoraproject.org/wiki/JavaFAQ for more information on the java-gcj-compat free Java environment in Fedora.
| | Include Location and Version Information in Bug Reports |
|---|---|
When making a bug report, be sure to include the output from these commands: which java && java -version && which javac && javac -version |
15.4. Handling Java and Java-like Packages
In addition to the java-gcj-compat free software stack, Fedora lets you install multiple Java implementations and switch between them using the alternatives command line tool. However, every Java system you install must be packaged using the JPackage Project packaging guidelines to take advantage of alternatives. Once these packages are installed properly, the root user may switch between java and javac implementations using the alternatives command:alternatives --config java alternatives --config javac
A simpler way to switch Java alternatives is using the sytsem-switch-java tool included in Fedora.
15.5. Fedora and the JPackage Java Packages
Fedora includes many packages derived from the JPackage Project, which provides a Java software repository. These packages are modified in Fedora to remove proprietary software dependencies and to make use of GCJ's ahead-of-time compilation feature. Use the Fedora repositories to update these packages, or use the JPackage repository for packages not provided by Fedora. Refer to the JPackage website at http://jpackage.org for more information on the project and the software it provides. ![[Warning]](http://download.fedora.redhat.com/pub/fedora/linux/releases/8/Everything/i386/os/stylesheet-images/warning.png) | Mixing Packages from Fedora and JPackage |
|---|---|
| Research package compatibility before you install software from both the Fedora and JPackage repositories on the same system. Incompatible packages may cause complex issues. |
15.6. Maven (v2)
This release of Fedora includes maven2, a Java project management and project comprehension tool. Maven can be invoked by the mvn and mvn-jpp commands. The former makes Maven behave just like upstream Maven, while the latter calls mvn with additional properties that make off-line building easier.The maven2 package in Fedora is modified to work in a fully off-line mode. With no additional properties defined (the mvn command), maven2 works exactly like upstream Maven. Users may define additional properties to facilitate off-line builds, or call mvn-jpp, a wrapper that defines the most commonly used properties for off-line building. The properties and their usage details are described in the /usr/share/doc/maven2-2.0.4/maven2-jpp-readme.html file, which comes from the maven2-manual package.
16. Multimedia
| | Latest Release Notes on the Web |
|---|---|
| These release notes may be updated. Visit http://docs.fedoraproject.org/release-notes/ to view the latest release notes for Fedora. |
16.1. Multimedia Players
The default installation of Fedora includes Rhythmbox and Totem for media playback. The Fedora repositories include many other popular programs such as the XMMS player and KDE's amaroK. Both GNOME and KDE have a selection of players that can be used with a variety of formats. Third parties may offer additional programs to handle other formats.Fedora also takes full advantage of the Advanced Linux Sound Architecture (ALSA) sound system. Many programs can play sound simultaneously, which was once difficult on Linux systems. When all multimedia software is configured to use ALSA for sound support, this limitation disappears. For more information about ALSA, visit the project website at http://www.alsa-project.org/. Users may still experience issues when multiple users log into the system. Depending upon hardware and software configurations, multiple users may not be able to use the sound hardware simultaneously.
16.2. Ogg and Xiph.Org Foundation Formats
Fedora includes complete support for the Ogg media container format and the Vorbis audio, Theora video, Speex audio, and FLAC lossless audio formats. These freely-distributable formats are not encumbered by patent or license restrictions. They provide powerful and flexible alternatives to more popular, restricted formats. The Fedora Project encourages the use of open formats in place of restricted ones. For more information on these formats and how to use them, refer to the Xiph.Org Foundation's web site at http://www.xiph.org/.16.3. MP3, DVD, and Other Excluded Multimedia Formats
Fedora software repositories cannot include support for MP3 or DVD video playback or recording. The MP3 formats are patented, and the patent holders have not provided the necessary patent licenses. DVD video formats are patented and equipped with an encryption scheme. The patent holders have not provided the necessary patent licenses, and the code needed to decrypt CSS-encrypted discs may violate the Digital Millennium Copyright Act, a copyright law of the United States. Fedora also excludes other multimedia software due to patent, copyright, or license restrictions, including Adobe's Flash Player and Real Media's Real Player. For more on this subject, please refer to http://fedoraproject.org/wiki/ForbiddenItems.While other MP3 options may be available for Fedora, Fluendo now offers a free MP3 plugin for GStreamer that has the necessary patent license for end users. This plugin enables MP3 support in applications that use the GStreamer framework as a backend. Fedora does not include this plugin since we prefer to support and encourage the use of patent unrestricted open formats instead. For more information about the MP3 plugin, visit Fluendo's website at http://www.fluendo.com/.
16.4. CD and DVD Authoring and Burning
Fedora software repositories includes a variety of tools for easily mastering and burning CDs and DVDs. GNOME users can burn directly from the Nautilus file manager, choose the gnomebaker or graveman packages, or utilize the older xcdroast package from Fedora. KDE users can use the robust k3b package for these tasks. Console tools include cdrecord, readcd, mkisofs, and other popular applications.16.5. Screencasts
You can use Fedora to create and play back screencasts, which are recorded desktop sessions, using open technologies. Fedora Package Collection software repository includes istanbul, which creates screencasts using the Theora video format. These videos can be played back using one of several players included in Fedora. This is the preferred way to submit screencasts to the Fedora Project for either developer or end-user use. For a more comprehensive how-to, refer to http://fedoraproject.org/wiki/ScreenCasting.16.6. Extended Support through Plugins
Most of the media players in Fedora software repositories can use plugins to add support for additional media formats and sound output systems. Some use powerful multimedia frameworks, like the gstreamer package, to handle media format support and sound output. Fedora software repositories offer plugin packages for these backends and for individual applications. Third parties may provide additional plugins to add even greater capabilities.17.

17.1. Haxima
Fedora 7 includes version 0.5.6 of the Nazghul old-school role playing game engine and its companion game Haxima. This version is not compatible with saved games from previous Nazghul versions, so those with Haxima games in progress need to restart their games after updating to Fedora 7.18. Virtualization

19.1. X Configuration Changes
The X.org 7.2 X server has been modified to automatically detect and configure most hardware, eliminating the need for users or administrators to modify the /etc/X11/xorg.conf configuration file. The only hardware configured by default in the xorg.conf file written by anaconda is:- The graphics driver
- The keyboard map
The X server queries the attached monitor for supported resolution ranges, and attempts to pick the highest resolution available with the correct aspect ratio for the display. Users can set their preferred resolution in System → Preferences → Screen Resolution, and the default resolution for the system can be changed with System → Administration → Display.
If the /etc/X11/xorg.conf configuration file is not present, X also automatically detects the appropriate driver, and assumes a 105-key US keyboard layout.
19.2. Intel Driver Notes
Fedora 7 contains two drivers for Intel integrated graphics controllers:- The default i810 driver, which contains support for Intel graphics chipsets up to and including i945 and i965
- The experimental intel driver, which contains support for Intel graphics chipsets up to and including i945
We welcome feedback on the experimental intel driver. Please report success in Bugzilla, attaching the full output of lspci -vn for your machine. Given success reports, various chipsets may be switched to use the intel driver by default.
19.3. Third Party Video Drivers
If you intend to use third party video drivers, refer to the Xorg third party drivers page for detailed guidelines:http://fedoraproject.org/wiki/Xorg/3rdPartyVideoDrivers

25.2. Production Methods
Beat writers produce the release notes directly on the Fedora Project Wiki. They collaborate with other subject matter experts during the test release phase of Fedora to explain important changes and enhancements. The editorial team ensures consistency and quality of the finished beats, and ports the Wiki material to DocBook XML in a revision control repository. At this point, the team of translators produces other language versions of the release notes, and then they become available to the general public as part of Fedora. The publication team also makes them, and subsequent errata, available via the Web.Related posts:
