To find out more general information about Fedora, refer to the following Web pages: ● Fedora Overview (http://fedoraproject.org/wiki/Overview) ● Fedora FAQ (http://fedoraproject.org/wiki/FAQ) ● Help and Support (http://fedoraproject.org/wiki/Communicate) ● Participate in the Fedora Project (http://fedoraproject.org/wiki/HelpWanted ) ● About the Fedora Project (http://fedora.redhat.com/About/) Fedora Core 5 Tour You can find a tour filled with pictures and videos of this exciting new release at http://fedoraproject.org/wiki/Tours/FedoraCore5. What Has Changed Since Fedora Core 4 This release is the culmination of nine months of development, and includes significant new versions of many key products and technologies. The following sections provide a brief overview of major changes from the last release of Fedora Core. Desktop Some of the highlights of this release include: ● There is a completely revamped appearance with a bubbly new theme and the first use of the new Fedora logo. ● Early work from the Fedora Rendering Project is integrated into the desktop. This new project (http://fedoraproject.org/wiki/RenderingProject) is going to provide the technical foundations for advanced desktop interfaces based on OpenGL. ● Popular desktop environments GNOME and KDE have innovative new versions included in this release. The GNOME desktop is based on the 2.14 release ( http://www.gnome.org/~davyd/gnome-2-14/), and the KDE 3.5 desktop is the general 3.5 release (http://kde.org/announcements/announce-3.5.php). ● The latest versions of GNOME Power Manager (http://www.gnome.org/projects/ gnome-power-manager/) and GNOME Screensaver(http://live.gnome.org/ GnomeScreensaver/) provide new and integrated power management capabilities. ● The new GNOME User Share facility provides simple and efficient file sharing. ● Suspend to RAM support has also been improved due to infrastructure work done by the hibernate support. ● The previous graphical software management utilities have been replaced with the first versions of a new generation of tools. This release includes Pup, a simple interface for system updates, and Pirut, a new package manager that replaces system-config-packages. These build on the yum utility, to provide consistent software installation and update facilities throughout the system. ● This release of Fedora includes Mono support for the first time, and Mono applications such as Beagle, a desktop search interface; F-Spot, a photo management utility; and Tomboy, a note-taking application. ● You can now enjoy enhanced multimedia support with version 0.10 of the Gstreamer media framework. This milestone release brings major improvements in robustness, compatibility, and features, over previous versions of Gstreamer. The Totem movie player and other media software in this release have been updated to use the new framework. ● There is dramatically improved internationalization support with SCIM in Fedora Core 5. The SCIM language input framework provides an easy to use interface for inputting many different non-English languages. SCIM replaces the IIIMF system used in previous Fedora releases. ● The default Web browser is Firefox 1.5 (http://www.mozilla.com/firefox/ releases/1.5.html), which has many new features for faster, safer, and more efficient browsing. ● The office applications suite OpenOffice.org 2.0 (http://www.openoffice.org /product/index.html) now makes better use of general system libraries for increased performance and efficiency. ● A large number of GTK and GNOME programs take advantage of the Cairo 2D graphics library (http://cairographics.org/), included in this release, to provide streamlined attractive graphical interfaces. ● There are new experimental drivers that provide support for the widely-used Broadcom 43xx wireless chipsets (http://bcm43xx.berlios.de/). ● This release includes libnotify, a library that features simple and attractive notifications for the desktop. ● Fedora Core 5 now uses gnome-mount, a more efficient mechanism that replaces fstab-sync, and uses HAL to handle mounting. ● Printing support is improved in this release with the inclusion of the hplip utility, which replaces hpijs. System Administration Improvements for administrators and developers include: ● The Xen virtualization system has enhanced support. The tools to configure Xen virtual machines on your Fedora Core 5 system now use the standard graphical installation process, run as a window on your desktop. Fedora developers have also created gnome-applet-vm, which provides a simple virtual domains monitor applet, and libvirt (http://libvirt.org/), a library providing an API to use Xen virtualization capabilities. ● The industry-leading anaconda installation system continues to evolve. New features for this release include remote logging and improved support for tracebacks. Package management in the installation system is now provided by yum. This enhancement is the first step in enabling access to Fedora Extras from within the installation process. ● Version 2.2 of the Apache HTTP server is now included. This release provides enhancements to authentication, database support, proxy facilities, and content filtering. ● The latest generation of database servers are packaged in this release, including both MySQL 5.0 and PostgreSQL 8.1. ● Several native Java programs are now available compiled with GCJ, such as the Geronimo J2EE server and the Apache Jakarta Project, in addition to the Java programs and development capabilities in the previous releases. ● There are new tools for system monitoring and performance analysis. This release includes SystemTap (http://fedoraproject.org/wiki/SystemTap), an instrumentation system for debugging and analyzing performance bottle necks, and Frysk (http://fedoraproject.org/wiki/Frysk), an execution analysis technology for monitoring running processes or threads. ● This release includes system-config-cluster, a utility that allows you to manage cluster configuration in a graphical setting. ● The combination of Kexec and Kdump utilities provides modern crash dumping facilities and potential for faster bootup, bypassing the firmware on reboots. Kexec loads a new kernel from a running kernel, and Kdump can provide a memory dump of the previous kernel for debugging. ● This release includes iscsi-initiator-utils, iSCSI daemon and utility programs that provide support for hardware using the iSCSI interface. System Level Changes ● X.org X11R7.0 is included in this release. The new modular architecture of R7.0 enables easier driver upgrades and simplifies development, opening the way for rapid improvement in Linux graphics. ● The GCC 4.1 compiler is included, and the entire set of Fedora packages is built with this technology. This provides security and performance enhancements throughout the system. ● The kernels for this release are based on Linux 2.6.16. Refer to the section on the kernel in these release notes for other details. ● The PCMCIA framework used by laptop and mobile devices has changed. The older pcmcia-cs package using the cardmgr/pcmcia service has been replaced with a new pcmciautils package. With pcmciautils, PCMCIA devices are handled directly and dynamically by the hotplug and udev subsystems. This update increases both efficiency and performance of the system. For more information about these changes, refer to http://www.kernel.org/pub/linux/ utils/kernel/pcmcia/pcmcia.html. ● SELinux implementation has undergone a major change, with a switch to the SELinux reference policy (http://serefpolicy.sourceforge.net/). The SELinux reference policy can support binary policy modules. It is now possible to move SELinux policies into individual packages, making it easier for users to ship site-specific policy customizations when required. This version also adds support for Multi-Category Security (MCS), enabled by default, and Multi-Level Security (MCS). SELinux continues to offer support for TE (Type Enforcement), enabled by default, and RBAC (Role-Based Access Control). Refer to the section on SELinux in these release notes for other details and links to SELinux resources on the Fedora Project pages.

Installation-Related Notes This section outlines those issues that are related to Anaconda (the Fedora Core installation program) and installing Fedora Core 5 in general. Downloading Large Files If you intend to download the Fedora Core 5 DVD ISO image, keep in mind that not all file downloading tools can accommodate files larger than 2GB in size. wget 1.9.1-16 and above, curl and ncftpget do not have this limitation, and can successfully download files larger than 2GB. BitTorrent is another method for downloading large files. For information about obtaining and using the torrent file, refer to http://torrent.fedoraproject.org/. Architecture Specific Notes This section provides notes that are specific to the supported hardware architectures of Fedora Core. PPC Specifics for Fedora This section covers any specific information you may need to know about Fedora Core and the PPC hardware platform. PPC Hardware Requirements Processor and Memory ● Minimum CPU: PowerPC G3 / POWER4 ● Fedora Core 5 supports only the “New World” generation of Apple Power Macintosh, shipped from circa 1999 onward. ● Fedora Core 5 also supports IBM eServer pSeries, IBM RS/6000, Genesi Pegasos II, and IBM Cell Broadband Engine machines. ● Recommended for text-mode: 233 MHz G3 or better, 128MiB RAM. ● Recommended for graphical: 400 MHz G3 or better, 256MiB RAM. Hard Disk Space Requirements The disk space requirements listed below represent the disk space taken up by Fedora Core 5 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 Installtion 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. 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. PPC Installation Notes Fedora Core Installation Disc 1 is bootable on supported hardware. In addition, a bootable CD image appears in the images/ directory of this disc. These images will behave differently according to your system hardware: ● Apple Macintosh The bootloader should automatically boot the appropriate 32-bit or 64-bit installer. 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 in Fedora Extras. Following installation, you can install apmud with the following command: su -c 'yum install apmud' ● 64-bit IBM eServer pSeries (POWER4/POWER5) After using OpenFirmware to boot the CD, the bootloader (yaboot) should automatically boot the 64-bit installer. ● 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, which does not work. ● Genesi Pegasos II At the time of writing, firmware with full support for ISO9660 file systems is not yet released for the Pegasos. However, you can use the network boot image. At the OpenFirmware prompt, enter the command: boot cd: /images/netboot/ppc32.img You must also configure OpenFirmware on the Pegasos manually to make the installed Fedora Core system bootable. To do this, set the boot-device and boot-file environment variables appropriately. ● Network booting You can find combined images containing the installer kernel and ramdisk in the images/netboot/ directory of the installation tree. These are intended for network booting with TFTP, but can be used in many ways. yaboot supports TFTP booting for IBM eServer pSeries and Apple Macintosh. The Fedora Project encourages the use of yaboot over the netboot images. x86 Specifics for Fedora This section covers any specific information you may need to know about Fedora Core and the x86 hardware platform. x86 Hardware Requirements In order to use specific features of Fedora Core 5 during or after installation, you may need to know details of other hardware components such as video and network cards. Processor and Memory Requirements 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 Core. ● Minimum: Pentium-class — Fedora Core 5 is optimized for Pentium 4 CPUs, but also supports earlier CPUs such as Pentium, Pentium Pro, Pentium II, Pentium III, and compatible AMD and VIA processors. Fedora takes this approach because Pentium-class optimizations actually result in reduced performance for non-Pentium class processors. In addition, scheduling for Pentium 4 processors, which make up the bulk of today's processors, is sufficiently different to warrant this change. ● Recommended for text-mode: 200 MHz Pentium-class or better ● Recommended for graphical: 400 MHz Pentium II or better ● AMD64 processors (both Athlon64 and Opteron) ● Intel processors with Intel® Extended Memory 64 Technology (Intel® EM64T) ● Minimum RAM for text-mode: 128MiB ● Minimum RAM for graphical: 192MiB ● Recommended for graphical: 256MiB Hard Disk Space Requirements The disk space requirements listed below represent the disk space taken up by Fedora Core 5 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. x86_64 Specifics for Fedora This section covers any specific information you may need to know about Fedora Core and the x86_64 hardware platform. x86_64 Hardware Requirements In order to use specific features of Fedora Core 5 during or after installation, you may need to know details of other hardware components such as video and network cards. Memory Requirements This list is for 64-bit x86_64 systems: ● Minimum RAM for text-mode: 128MiB ● Minimum RAM for graphical: 256MiB ● Recommended RAM for graphical: 512MiB Hard Disk Space Requirements The disk space requirements listed below represent the disk space taken up by Fedora Core 5 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. RPM Multiarch Support on x86_64 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 in Fedora Extras, 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" Package Notes The following sections contain information regarding software packages that have undergone significant changes for Fedora Core 5. For easier access, they are generally organized using the same groups that are shown in the installation system. Kernel device, module loading, and hotplug changes The hotplug and device handling subsystem has undergone significant changes in Fedora Core 5. The udev method now handles all module loading, both on system boot and for hotplugged devices. The hotplug package has been removed, as it is no longer needed. Support for hotplug helpers via the /etc/hotplug, /etc/hotplug.d, and /etc/ dev.d directories is deprecated, and may be removed in a future Fedora Core release. These helpers should be converted to udev rules. Please see http:// www.reactivated.net/writing_udev_rules.html for examples. Systemwide Search Changes mlocate Has Replaced slocate The new mlocate package provides the implementations of /usr/bin/locate and / usr/bin/updatedb. Previous Fedora releases included the slocate versions of these programs. ● The locate command should be completely compatible. ● The configuration file /etc/updatedb.conf is compatible. ● Syntax errors that slocate would not detect are now reported. ● The DAILY_UPDATE variable is not supported. ● The updatedb command is not compatible, and custom scripts that use updatedb may have to be updated. Mouse Configuration Utility Removed The system-config-mouse configuration utility has been dropped in this release because synaptic and three-button mouse configuration is handled automatically. Serial mice are no longer supported. NetworkManager Fedora systems use Network Manager to automatically detect, select, and configure wired and wireless network connections. Wireless network devices may require third-party software or manual configuration to activate after the installation process completes. For this reason, Fedora Core 5 provides Network Manager as an optional component. Refer to http://fedoraproject.org/wiki/Tools/NetworkManager for more information on how to install and enable Network Manager. Dovecot Fedora Core 5 includes a new version of the dovecot IMAP server software, which has has many changes in its configuration file. These changes are of particular importance to users upgrading from a previous release. Refer to http:// wiki.dovecot.org/UpgradingDovecot for more information on the changes. Kudzu The kudzu utility, libkudzu library, and /etc/sysconfig/hwconf hardware listing are all deprecated, and will be removed in a future release of Fedora Core. Applications which need to probe for available hardware should be ported to use the HAL library. More information on HAL is available at http://freedesktop.org /wiki/Software/hal. No automatic fstab editing for removable media The fstab-sync facility has been removed. In Fedora Core , the fstab-sync program is removed in favor of desktop specific solutions for mounting removable media. Entries for hotplug devices or inserted media are no longer automatically added to the /etc/fstab file. Command-line users may migrate to gnome-mount, which provides similar functionality. GnuCash The PostgreSQL backend for GnuCash has been removed, as it is unmaintained upstream, does not support the full set of GnuCash features, and can lead to crashes. Users who use the PostgreSQL backend should load their data and save it as an XML file before upgrading GnuCash. Mozilla The Mozilla application suite is deprecated. It is shipped in Fedora Core 5 and applications can expect to build against mozilla-devel, however it will be removed in a future release of Fedora Core. libstc++ preview The libstdc++so7 package has been added. This package contains a preview of the GNU Standard C++ Library from libstdcxx_so_7-branch. It is considered experimental and unsupported. Do not build any production software against it, as its ABI and so-version will change in future upgrades. To build software using this library, invoke g++-libstdc++so_7 instead of g++. LinuxThreads support removed The LinuxThreads library is no longer available. LinuxThreads was deprecated in Fedora Core 4 and is no longer available in this release. The Native POSIX Threading Library (NPTL), which has been the default threading library since Red Hat Linux 9, has replaced LinuxThreads completely. Linux Kernel This section covers changes and important information regarding the kernel in Fedora Core 5. Version This distribution is based on the 2.6 series of the Linux kernel. Fedora Core may include additional patches for improvements, bug fixes, or additional features. For this reason, the Fedora Core 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-.src.rpm Changelog To retrieve a log of changes to the package, run the following command: rpm -q --changelog kernel- 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.fedora.redhat.com . Kernel Flavors Fedora Core 5 includes the following kernel builds: ● Native kernel, in both uni-processor and SMP (Symmetric Multi-Processor) varieties. SMP kernels provide support for multiple CPUs. Configured sources are available in the kernel-[smp-]devel-..rpm package. ● Virtual kernel hypervisor for use with the Xen emulator package. Configured sources are available in the kernel-xen0-devel-..rpm package. ● Virtual kernel guest for use with the Xen emulator package. Configured sources are available in the kernel-xenU-devel-..rpm package. ● Kdump kernel for use with kexec/kdump capabilities. Configured sources are available in the kernel-kdump-devel-..rpm package. You may install sources for all kernel flavors at the same time. The files are installed in the /usr/src/kernels/-[xen0|xenU|kdump]-/ tree. Use the following command: su -c 'yum install kernel-{xen0,xenU,kdump}-devel' Select one or more of these flavors, separated by commas and no spaces, as appropriate. Enter the root password when prompted. x86_64 Default Kernel Provides SMP There is no separate SMP kernel available for the x86_64 architecture in Fedora Core 5. PowerPC Kernel Support There is no support for Xen or kdump for the PowerPC architecture in Fedora Core 5. 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 which are specific to Fedora. Following Generic Textbooks Many of the tutorials, examples, and textbooks about Linux kernel development assume the kernel sources are installed under the /usr/src/linux/ directory. If you make a symbolic link, as shown below, you should be able to use those learning materials with the Fedora Core packages. Install the appropriate kernel sources, as shown earlier, and then run the following command: su -c 'ln -s /usr/src/kernels/kernel- /usr/src/linux' Enter the root password when prompted. Preparing for Kernel Development Fedora Core 5 does not include the kernel-source package provided by older versions. Instead, configured sources are available, as described in this kernel flavors section. Instructions Refer to Current Kernel To simplify the following directions, we have assumed that you want to configure the kernel sources to match your currently-running kernel. In the steps below, the expression refers to the kernel version shown by the command: uname -r. Users who require access to Fedora Core original kernel sources can find them in the kernel .src.rpm package. To create an exploded source tree from this file, perform the following steps: Do Not Build Packages as Super-user Building packages as the superuser is inherently dangerous and is not required, even for the kernel. These instructions allow you to install the kernel source as a normal user. Many general information sites refer to /usr/src/linux in their kernel instructions. If you use these instructions, simply substitute ~/ rpmbuild/BUILD/kernel-/linux-. 1. Prepare a RPM package building environment in your home directory. Run the following commands: su -c 'yum install fedora-rpmdevtools' fedora-buildrpmtree Enter the root password when prompted. 2. Obtain the kernel-.src.rpm file from one of the following sources: ● the SRPMS directory on the appropriate SRPMS CD iso image ● the HTTP or FTP site where you got the kernel package ● by running the following command: su -c 'yum install yum-utils' su -c 'yumdownloader --source kernel' Enter the root password when prompted. 3. Install kernel-.src.rpm using the command: rpm -Uvh kernel-.src.rpm` This command writes the RPM contents into ${HOME}/rpmbuild/SOURCES and $ {HOME}/rpmbuild/SPECS, where ${HOME} is your home directory. Space Required The full kernel building process may require several gigabytes of extra space on the file system containing your home directory. 4. Prepare the kernel sources using the commands: cd ~/rpmbuild/SPECS rpmbuild -bp --target $(uname -m) kernel-2.6.spec The kernel source tree is located in the ${HOME}/rpmbuild/BUILD/kernel- / directory. 5. The configurations for the specific kernels shipped in Fedora Core 5 are in the configs/ directory. For example, the i686 SMP configuration file is named configs/kernel--i686-smp.config. Issue the following command to place the desired configuration file in the proper place for building: cp configs/ .config You can also find the .config file that matches your current kernel configuration in the /lib/modules//build/.config file. 6. Every kernel gets a name based on its version number. This is the value the uname -r command displays. The kernel name is defined by the first four lines of the kernel Makefile. The Makefile has been changed to generate a kernel with a different name from that of the running kernel. To be accepted by the running kernel, a module must be compiled for a kernel with the correct name. To do this, you must edit the kernel Makefile. For example, if the uname -r returns the string 2.6.15-1.1948_FC5, change the EXTRAVERSION definition from this: EXTRAVERSION = -prep to this: EXTRAVERSION = -1.1948_FC5 That is, substitute everything from the final dash onward. 7. Run the following command: make oldconfig You may then proceed as usual. Building Only Kernel Modules An exploded source tree is not required to build a kernel module, such as your own device driver, against the currently in-use kernel. For example, to build the foo.ko module, create the following Makefile in the directory containing the foo.c file: obj-m := foo.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) M=$(PWD) modules Issue the make command to build the foo.ko module. User Space Dependencies on the Kernel Fedora Core 5 has support for clustered storage through the Global File System (GFS). GFS requires special kernel modules that work in conjunction with some user-space utilities, such as management daemons. To remove such a kernel, perhaps after an update, use the su -c 'yum remove kernel-' command instead. The yum command automatically removes dependent packages, if necessary. PowerPC does not support GFS The GFS kernel modules are not built for the PowerPC architecture in Fedora Core 5. Fedora Desktop GNOME 2.14 (or a release candidate) and KDE 3.5.1 are included in Fedora Core 5. The following list includes notable changes to the desktop interface in this release. ● gnome-power-manager ○ The GNOME Power Manager is a session daemon for the GNOME desktop environment that makes it easy to manage your laptop or desktop system. It takes advantage of HAL (which provides a hardware abstraction layer) and DBUS (Inter Process Communication software) written and maintained by Fedora Core developers. ● gnome-screensaver ○ The GNOME Screensaver provides an integrated user interface to screensavers and the lock screen dialog. ● Memory optimizations in the fontconfig and shared-mime-info packages. These now use shared memory-mapped caches for this data. ● Starting with GNOME 2.12, the terminal option has been removed from the desktop context menu. The nautilus-open-terminal package in Fedora Extras provides a enhanced replacement for those who require it. You can install it with the following command. su -c 'yum install nautilus-open-terminal' ● In Fedora Core 5, only a small assortment of screensavers is installed by default. Some users find certain screensavers unpleasant, and other screensavers may abruptly terminate the graphical interface. This tends to happen more often with OpenGL animated screensavers provided within the xscreensaver-gl-extras package, when used with poorly-supported video hardware. To install these extra screensavers, run the following command: su -c 'yum install xscreensaver-extras xscreensaver-gl-extras' Server Tools This section highlights changes and additions to the various GUI server and system configuration tools in Fedora Core. system-config-printer SMB Browsing Outside Local Network You can now browse for Samba print shares across subnets. If you specify at least one WINS server in /etc/samba/smb.conf, the first address is used when browsing. Kerberos Support for SMB Printers The system-config-printer application supports Kerberos authentication when adding a new SMB printer. To add the printer, the user must possess a valid Kerberos ticket and launch the printer configuration tool. Select System> Administration>Printing from the main menu, or use the following command: su -c 'system-config-printer' No username and password is stored in /etc/cups/printers.conf. Printing is still possible if the SMB print queue permits anonymous printing. system-config-securitylevel Trusted Service Additions Samba is now listed in the Trusted services list. To permit the firewall to pass SMB traffic, enable this option. Port Ranges When you define Other Ports in the system-config-securitylevel tool, you may now specify port ranges. For example, if you specify 6881-6999:tcp, the following line is added to /etc/sysconfig/iptables: A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 6881:6999 -j ACCEPT File Servers General Information This section refers to file transfer and sharing servers. Refer to http:// fedoraproject.org/wiki/Docs/Beats/WebServers and http://fedoraproject.org/wiki/ Docs/Beats/Samba for information on HTTP (Web) file transfer and Samba (Windows) file sharing services. Netatalk (Macintosh Compatibility) Fedora includes version 2 of Netatalk, a suite of software that enables Linux to interact with Macintosh systems using the AppleTalk network protocols. Use Caution When Upgrading You may experience data loss when upgrading from Netatalk version 1 to version 2. Version 2 of Netatalk stores file resource forks using a different method from the previous version, and may require a different file name encoding scheme. Please read the documentation and plan your migration before upgrading. Refer to the upgrade information available directly from the Netatalk site at http:// netatalk.sourceforge.net/2.0/htmldocs/upgrade.html. The documentation is also included in the netatalk package. Refer to either / usr/share/doc/netatalk-2.0.2/doc/htmldocs/upgrade.html or /usr/share/doc/ netatalk-2.0.2/doc/Netatalk-Manual.pdf (numbered page 25, document page 33). Web Servers This section contains information on Web-related applications. httpd Fedora Core now includes version 2.2 of the Apache HTTP Server. This release brings a number of improvements over the 2.0 series, including: ● greatly improved caching modules (mod_cache, mod_disk_cache, mod_mem_cache) ● a new structure for authentication and authorization support, replacing the security modules provided in previous versions ● support for proxy load balancing (mod_proxy_balance) ● large file support for 32-bit platforms (including support for serving files larger than 2GB) ● new modules mod_dbd and mod_filter, which bring SQL database support and enhanced filtering Upgrading and Security Modules If you upgrade from a previous version of httpd, update your server configuration to use the new authentication and authorization modules. Refer to the page listed below for more details. The following changes have been made to the default httpd configuration: ● The mod_cern_meta and mod_asis modules are no longer loaded by default. ● The mod_ext_filter module is now loaded by default. Third-party Modules Any third-party modules compiled for httpd 2.0 must be rebuilt for httpd 2.2. For more information on upgrading existing installations, refer to http:// httpd.apache.org/docs/2.2/upgrading.html. php Version 5.1 of PHP is now included in Fedora Core. This release brings a number of improvements since PHP 5.0, including: ● improved performance ● addition of the PDO database abstraction module The following extension modules have been added: ● date, hash, and Reflection (built-in with the php package) ● pdo and pdo_psqlite (in the php-pdo package) ● pdo_mysql (in the php-mysql package) ● pdo_pgsql (in the php-pgsql package) ● pdo_odbc (in the php-odbc package) ● xmlreader and xmlwriter (in the php-xml package) The following extension modules are no longer built: ● dbx ● dio ● yp The PEAR framework The PEAR framework is now packaged in the php-pear package. Only the following PEAR components are included in Fedora Core: ● Archive_Tar ● Console_Getopt ● XML_RPC Additional components may be packaged in Fedora Extras. Developer Tools This section covers various developer tools. GCC Compiler Collection This release of Fedora has been built with GCC 4.1 as the system compiler, which is included with the distribution. Caveats ● You need GDB 6.1 or newer to debug binaries, unless they are compiled using the -fno-var-tracking compilation option. ● The -fwritable-strings option is no longer accepted. ● English-language diagnostic messages now use Unicode quotes. If you cannot read this, set your LC_CTYPE environment variable to C or change your terminal emulator. ● The specs file is no longer installed on most systems. Ordinary users will not notice, but developers who need to alter the file can use the -dumpspecs option to generate the file for editing. Code Generation ● The SSA code optimizer is now included and brings with it better constant propagation, partial redundancy elimination, load and store code motion, strength reduction, dead storage elimination, better detection of unreachable code, and tail recursion by accumulation. ● Autovectorization is supported. This technique achieves higher performance for repetitive loop code, in some circumstances. Language Extensions ● The new sentinel attribute causes the compiler to issue a warning if a function such as execl(char *path, const char *arg, ...), which requires a NULL list terminator, is missing the NULL. ● The cast-as-lvalue, conditional-expression-as-lvalue, and compund-expression-as-lvalue extensions have been removed. ● The #pragma pack() semantics are now closer to those used by other compilers. ● Taking the address of a variable declared with the register modifier now generates an error instead of a warning. ● Arrays of incomplete element types now generate an error. This implies no forward reference to structure definitions. ● The basic compiler, without any optimization (-O0), has been measured as much as 25% faster in real-world code. ● Libraries may now contain function-scope static variables in multi-threaded programs. Embedded developers can use the -fno-threadsafe-statics to turn off this feature, but ordinary users should never do this. FORTRAN ● The GNU FORTRAN 77 front end has been replaced by a new FORTRAN 90/95 recognizer. Eclipse Development Environment ● Eclipse 3.1M6 is compiled as a native application. ● The C Development Tool (CDT) has been included. Security This section highlights various security items from Fedora Core. A general introduction to the many proactive security features in Fedora, current status and policies is available at http://fedoraproject.org/wiki/ Security. What's New PAM module Deprecation Pam_stack is deprecated in this release. Linux-PAM 0.78 and later contains the include directive which obsoletes the pam_stack module. pam_stack module usage is logged with a deprecation warning. It might be removed in a future release. It must not be used in individual service configurations anymore. All packages in Fedora Core using PAM were modified so they do not use it. Upgrading and PAM Stacks When a system is upgraded from previous Fedora Core releases and the system admininstrator previously modified some service configurations, those modified configuration files are not replaced when new packages are installed. Instead, the new configuration files are created as .rpmnew files. Such service configurations must be fixed so the pam_stack module is not used. Refer to the .rpmnew files for the actual changes needed. diff -u /etc/pam.d/foo /etc/pam.d/foo.rpmnew The following example shows the /etc/pam.d/login configuration file in its original form using pam_stack, and then revised with the include directive. #%PAM-1.0 auth required pam_securetty.so auth required pam_stack.so service=system-auth auth required pam_nologin.so account required pam_stack.so service=system-auth password required pam_stack.so service=system-auth # pam_selinux.so close should be the first session rule session required pam_selinux.so close session required pam_stack.so service=system-auth session required pam_loginuid.so session optional pam_console.so # pam_selinux.so open should be the last session rule session required pam_selinux.so open #%PAM-1.0 auth required pam_securetty.so auth include system-auth # no module should remain after 'include' if 'sufficient' might # be used in the included configuration file # pam_nologin moved to account phase - it's more appropriate there # other modules might be moved before the system-auth 'include' account required pam_nologin.so account include system-auth password include system-auth # pam_selinux.so close should be the first session rule session required pam_selinux.so close session include system-auth # the system-auth config doesn't contain sufficient modules # in the session phase session required pam_loginuid.so session optional pam_console.so # pam_selinux.so open should be the last session rule session required pam_selinux.so open Buffer Overflow detection and variable reordering All of the software in Fedora Core and Extras software repository for this release is compiled using a security feature called fstack-protector. fstack-protector places a canary value on the stack of functions containing a local character array. Before returning from a protected function, the canary value is verified. If there was a buffer overflow, the canary will no longer match the expected value, aborting the program. The canary value is random each time the application is started, making remote exploitation very difficult. The fstack-protector feature does not protect against heap-based buffer overflows. This is a security feature written by Red Hat developers, implementing the IBM ProPolice/SSP feature. For more information about ProPolice/SSP, refer to http: //www.research.ibm.com/trl/projects/security/ssp/. This feature is available as part of the GCC 4.1 compiler used in Fedora Core 5. The FORTIFY_SOURCE security feature for gcc and glibc introduced in Fedora Core 4 remains available. For more information about security features in Fedora, refer to http://fedoraproject.org/wiki/Security/Features. SELinux The new 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://fedora.redhat.com/docs/selinux-faq/ ● Listing of SELinux commands: http://fedoraproject.org/wiki/SELinux/Commands ● Details of confined domains: http://fedoraproject.org/wiki/SELinux/Domains Multi Category Security (MCS) MCS is a general-use implementation of the more stringent Multilevel Security (MLS). MCS is an enhancement to SELinux to allow users to label files with categories. Categories might include Company_Confidential, CEO_EYES_ONLY, or Sysadmin_Passwords. For more information about MCS, refer to http:// james-morris.livejournal.com/5583.html, an article by the author. Multilevel Security (MLS) MLS is a specific Mandatory Access Control (MAC) scheme that labels processes and objects with special security levels. For example, an object such as a document file can have the security level of { Secret, ProjectMeta }, where Secret is the sensitivity level, and ProjectMeta is the category. For more information about MLS, refer to http://james-morris.livejournal.com/5020.html. CategorySecurity Java and java-gcj-compat A free and open source Java environment is available within this Fedora Core release, called java-gcj-compat. java-gcj-compat 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. Fedora Core Does Not Include Java Java is a trademark of Sun Microsystems. java-gcj-compat is an entirely free software stack that is not Java, but may run Java software. The java-gcj-compat 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 included in this Fedora release use the new, integrated 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 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 Handling Java and Java-like Packages In addition to the java-gcj-compat free software stack, Fedora Core is designed to let 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 installed properly, the root user should be able to switch between java and javac implementations using the alternatives command: alternatives --config java alternatives --config javac Fedora and the JPackage Java Packages Fedora Core includes many packages derived from the JPackage Project, which provides a Java software repository. These packages have been modified in Fedora to remove proprietary software dependencies and to make use of GCJ's ahead-of-time compilation feature. Fedora users should use the Fedora repositories for updates to these packages, and may 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 that it provides. 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. Samba (Windows Compatibility) Fedora can now browse Windows shares, a feature known as SMB browsing. In releases prior to Fedora Core 5, the firewall prevented the proper function of SMB browsing. With the addition of the ip_conntrack_netbios_ns kernel module to the 2.6.14 kernel, and corresponding enhancements to system-config-securitylevel, the firewall now properly handles SMB broadcasts and permits network browsing. Multimedia Fedora Core includes applications for assorted multimedia functions, including playback, recording and editing. Additional packages are available through the Fedora Extras repository. Multimedia Players The default installation of Fedora Core includes Rhythmbox, Totem, and Helix Player for media playback. Many other programs are available in the Fedora Core and Fedora Extras repositories, including the popular XMMS package. Both GNOME and KDE have a selection of players that can be used with a variety of formats. Additional programs are available from third parties to handle other formats. Fedora Core 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/. 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 source 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/. MP3, DVD and Other Excluded Multimedia Fedora Core and Fedora Extras cannot include support for MP3 or DVD playback or recording, because the MP3 and MPEG (DVD) formats are patented, and the patent owners have not provided the necessary licenses. Fedora also excludes several multimedia application programs due to patent or license restrictions, such as Flash Player and Real Player. For more on this subject, please refer to http:// fedoraproject.org/wiki/ForbiddenItems. CD and DVD Authoring and Burning Fedora Core and Extras include a variety of tools for easily mastering and burning CDs and DVDs. GNOME users can burn directly from the Nautilus file manager, or choose the gnomebaker or graveman packages from Fedora Extras, or the older xcdroast package from Fedora Core. KDE users can use the robust k3b package for these tasks. Console tools include cdrecord, readcd, mkisofs, and other typical Linux applications. Screencasts You can use Fedora to create and play back screencasts, which are recorded desktop sessions, using open technologies. Fedora Extras 5 includes istanbul, which creates screencasts using the Theora video format. These videos can be played back using one of several players included in Fedora Core. 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. Extended Support through Plugins Most of the media players in Fedora Core and Fedora Extras support the use of plugins to add support for additional media formats and sound output systems. Some use powerful backends, like gstreamer, to handle media format support and sound output. Plugin packages for these backends and for individual applications are available in Fedora Core and Fedora Extras, and additional plugins may be available from third parties to add even greater capabilities. Games and Entertainment Fedora Core and Fedora Extras provide a selection of games that cover a variety of genres. By default, Fedora Core includes a small package of games for GNOME (called gnome-games). To install other games available from Fedora Core and Fedora Extras, select Applications>Add/Remove Software from the main desktop menu. Networking Major Kernel Changes 2.6.11 - 2.6.15 Refer to http://wiki.kernelnewbies.org/LinuxChanges for a list of major changes. Some of them are highlighted below. IPv4 Address Promotion Starting with version 2.6.12 of the kernel, a new feature has been added called named address promotion. This feature allows secondary IPv4 addresses to be promoted to primary addresses. Usually when the primary address is deleted, all secondary addresses are deleted as well. If you enable the new sysctl key net.ipv4.conf.all.promote_secondaries, or one of the interface specific variants, you can change this behavior to promote one of the secondary addresses to be the new primary address. Configurable Source Address for ICMP Errors By default, when selecting the source address for ICMP error messages, the kernel uses the address of the interface on which the ICMP error is going to be sent. Kernel version 2.6.12 introduces the new sysctl key net.ipv4.icmp_errors_use_inbound_ifaddr. If you enable this option the kernel uses the address of the interface that received the original error-causing packet. Suppose the kernel receives a packet on interface eth0 which generates an ICMP error, and the routing table causes the error message to be generated on interface eth1. If the new sysctl option is enabled, the ICMP error message indicates the source address as interface eth0, instead of the default eth1. This feature may ease network debugging in asynchronous routing setups. LC-Trie Based Routing Lookup Algorithm A new routing lookup algorithm called trie has been added. It is intended for large routing tables and shows a clear performance improvement over the original hash implementation, at the cost of increased memory consumption and complexity. Pluggable Congestion Control Algorithm Infrastructure TCP congestion control algorithms are now pluggable and thus modular. The legacy NewReno algorithm remains the default, and acts as the fallback algorithm. The following new congestion control algorithms have been added: ● High Speed TCP congestion control ● TCP Hybla congestion avoidance ● H-TCP congestion control ● Scalable TCP congestion control All existing congestion control modules have been converted to this new infrastructure, and the BIC congestion control has received enhancements from BICTCP 1.1 to handle low latency links. Affecting the Congestion Control Algorithm The congestion control algorithm is socket specific, and may be changed via the socket option TCP_CONGESTION. Queue Avoidance upon Carrier Loss When a network driver notices a carrier loss, such as when the cable is pulled out, the driver stops the queue in front of the driver. In the past, this stoppage caused the packets to be queued at the queueing discipline layer for an unbound period of time causing unexpected effects. In order to prevent this effect, the core networking stack now refuses to queue any packets for a device that is operationally down, that is, has its queue disabled. DCCP Protocol Support Kernel version 2.6.14-rc1 was the first version to receive support for the DCCP protocol. The implementation is still experimental, but is known to work. Developers have begun work to make userspace applications aware of this new protocol. Wireless A new HostAP driver appears in the kernel starting in 2.6.14-rc1, which allows the emulation of a wireless access point through software. Currently this driver only works for Intersil Prism2-based cards (PC Card/PCI/PLX). Support for wireless cards Intel(R) PRO/Wireless 2100 and 2200 has been added. Miscellaneous ● Many TCP Segmentation Offloading (TSO) related fixes are included. ● A new textsearch infrastructure has been added, and is usable with corresponding iptables and extended match. ● Both the IPv4 and IPv6 multicast joining interface visible by userspace have been reworked and brought up to the latest standards. ● The SNMPv2 MIB counter ipInAddrErrors is supported for IPv4. ● Various new socket options proposed in Advanced API (RFC3542) have been added. User Tools The IPv4 address deletion algorithm did not take the prefix length into account up to kernel version 2.6.12. Since this has changed, the iproute2 tool now issues a warning if no prefix length is provided, to warn about possible unintended deletions: ip addr list dev eth0 4: eth0: mtu 1500 qdisc pfifo_fast qlen 1000 inet 10.0.0.3/24 scope global eth0 su -c 'ip addr del 10.0.0.3 dev eth0' Warning: Executing wildcard deletion to stay compatible with old scripts. Explicitly specify the prefix length (10.0.0.3/32) to avoid this warning. This special behaviour is likely to disappear in further releases, fix your scripts! The correct method of deleting the address and thus avoiding the warning is: su -c 'ip addr del 10.0.0.3/24 dev eth0' Previously, it was not possible to tell if an interface was down administratively or because no carrier was found, such as if a cable were unplugged. The new flag NO-CARRIER now appears as a link flag if the link is administratively up but no carrier can be found. The ip command now supports a batch mode via the argument -batch, which works similar to the tc command to speed up batches of tasks. Virtualization Virtualization in Fedora Core is based on Xen. Xen 3.0 is integrated within Fedora Core 5 in the installer. Refer to http://fedoraproject.org/wiki/Tools/ Xen for more information about Xen. No PowerPC Support Xen is not supported on the PowerPC architecture in Fedora Core 5. X Window System (Graphics) This section contains information related to the X Window System implementation provided with Fedora. xorg-x11 X.org X11 is an open source implementation of the X Window System. It provides the basic low-level functionality upon which full-fledged graphical user interfaces (GUIs) such as GNOME and KDE are designed. For more information about X.org, refer to http://xorg.freedesktop.org/wiki/. You may use Applications > System Settings > Display or system-config-display to configure the settings. The configuration file for X.org is located in /etc/ X11/xorg.conf. X.org X11R7 is the first modular release of X.org, which, among several other benefits, promotes faster updates and helps programmers rapidly develop and release specific components. More information on the current status of the X.org modularization effort in Fedora is available at http://fedoraproject.org/ wiki/Xorg/Modularization. X.org X11R7 End-User Notes Installing Third Party Drivers Before you install any third party drivers from any vendor, including ATI or nVidia, please read http://fedoraproject.org/wiki/Xorg/3rdPartyVideoDrivers. The xorg-x11-server-Xorg package install scripts automatically remove the RgbPath line from the xorg.conf file if it is present. You may need to reconfigure your keyboard differently from what you are used to. You are encouraged to subscribe to the upstream xorg@freedesktop.org mailing list if you do need assistance reconfiguring your keyboard. X.org X11R7 Developer Overview The following list includes some of the more visible changes for developers in X11R7: ● The entire buildsystem has changed from imake to the GNU autotools collection. ● Libraries now install pkgconfig *.pc files, which should now always be used by software that depends on these libraries, instead of hard coding paths to them in /usr/X11 R6/lib or elsewhere. ● Everything is now installed directly into /usr instead of /usr/X11 R6. All software that hard codes paths to anything in /usr/X11 R6 must now be changed, preferably to dynamically detect the proper location of the object. Developers are strongly advised against hard-coding the new X11R7 default paths. ● Every library has its own private source RPM package, which creates a runtime binary subpackage and a -devel subpackage. X.org X11R7 Developer Notes This section includes a summary of issues of note for developers and packagers, and suggestions on how to fix them where possible. The /usr/X11R6/ Directory Hierarchy X11R7 files install into /usr directly now, and no longer use the /usr/X11 R6/ hierarchy. Applications that rely on files being present at fixed paths under / usr/X11 R6/, either at compile time or run time, must be updated. They should now use the system PATH, or some other mechanism to dynamically determine where the files reside, or alternatively to hard code the new locations, possibly with fallbacks. Imake The imake utility is no longer used to build the X Window System, and is now officially deprecated. X11R7 includes imake, xmkmf, and other build utilities previously supplied by the X Window System. X.Org highly recommends, however, that people migrate from imake to use GNU autotools and pkg-config. Support for imake may be removed in a future X Window System release, so developers are strongly encouraged to transition away from it, and not use it for any new software projects. The Systemwide app-defaults/ Directory The system app-defaults/ directory for X resources is now %{_datadir}/X11/ app-defaults, which expands to /usr/share/X11/app-defaults/ on Fedora Core 5 and for future Red Hat Enterprise Linux systems. Correct Package Dependencies Any software package that previously used Build Requires: (XFree86-devel| xorg-x11-devel) to satisfy build dependencies must now individually list each library dependency. The preferred and recommended method is to use virtual build dependencies instead of hard coding the library package names of the xorg implementation. This means you should use Build Requires: libXft-devel instead of Build Requires: xorg-x11-Xft-devel. If your software truly does depend on the X.Org X11 implementation of a specific library, and there is no other clean or safe way to state the dependency, then use the xorg-x11-devel form. If you use the virtual provides/requires mechanism, you will avoid inconvenience if the libraries move to another location in the future. xft-config Modular X now uses GNU autotools and pkg-config for its buildsystem configuration and execution. The xft-config utility has been deprecated for some time, and pkgconfig *.pc files have been provided for most of this time. Applications that previously used xft-config to obtain the Cflags or libs build options must now be updated to use pkg-config. Database Servers MySQL Fedora now provides MySQL 5.0. For a list of the enhancements provided by this version, refer to http://dev.mysql.com/doc/refman/5.0/en/ mysql-5-0-nutshell.html. For more information on upgrading databases from previous releases of MySQL, refer to the MySQL web site at http://dev.mysql.com/doc/refman/5.0/en/ upgrade.html. PostgreSQL This release of Fedora includes PostgreSQL 8.1. For more information on this new version, refer to http://www.postgresql.org/docs/whatsnew/. Database Upgrade Across Fedora Core Versions Fedora Core 4 provided version 8.0 of PostgreSQL. If you upgrade an existing Fedora system with a PostgreSQL database, you must upgrade the database to access the data. To upgrade a database from a previous version of PostgreSQL, follow the procedure described at http://www.postgresql.org/docs/8.1/interactive/ install-upgrading.html. Internationalization (i18n) This section includes information related to the support of various languages under Fedora Core. Input Methods SCIM (Simple Common Input Method) has replaced IIIMF as the input method system for Asian and other languages in Fedora Core in this release. SCIM uses Ctrl-Space as the default trigger key to toggle on and off the input method, though it is easy to change the hotkey or add hotkeys with the SCIM setup configuration tool. When scim-anthy is active Japanese users can now use the Zenkaku_Hankaku key to toggle between Japanese and ASCII input. Installation SCIM should be installed and run by default for Asian language desktops. Otherwise the required packages can be installed using the language support section of the package manager or running: su -c 'yum install ' where should be replaced by one or more of the following: ● Japanese: scim-anthy Korean: scim-hangul Simplified Chinese: scim-pinyin scim-tables-chinese Traditional Chinese: scim-chewing scim-tables-chinese Indian and other languages: scim-m17n m17n-db- You also need fonts for the language. The font packages are named fonts- , where is one of arabic, bengali, chinese, gujarati, hebrew, hindi, japanese, korean, punjabi, tamil. If your desktop is not running in an Asian locale, to activate it in your user account, run these commands, then logout and login again to your desktop. mkdir ~/.xinput.d ln -s /etc/X11/xinit/xinput.d/scim ~/.xinput.d/default SCIM applet and toolbar When SCIM is running, an applet icon appears in the notification area of the desktop panel. The icon is a grey keyboard icon when SCIM is inactive, and an Input Method Engine (IME) icon when it is active. When SCIM is active, by default the SCIM input method toolbar with status information also appears. Clicking the left mouse button on the applet activates a SCIM language switching menu for changing the current Input Method Engine. The menu only appears when an application using the Input Method has focus. Clicking the right mouse button on the applet or SCIM toolbar activates the setup menu. SCIM configuration You can configure SCIM and IMEs using the setup configuration tool available from the setup menu. In the IME general configuration pane, you can select which languages or IMEs appear on the language switching menu. New conversion engines anthy, a new Japanese conversion engine replaces the old Canna server system, and libchewing, a new Traditional Chinese conversion engine, has been added. Fonts Support is now available for synthetic emboldening of fonts that do not have a bold face. New fonts for Chinese have been added: AR PL ShanHeiSun Uni (uming.ttf) and AR PL ZenKai Uni (ukai.ttf). The default font is AR PL ShanHeiSun Uni, which contains embedded bitmaps. If you prefer outline glyphs you can put the following section in your ~/.font.conf file: AR PL ShanHeiSun Uni false gtk2 IM submenu The Gtk2 context menu IM submenu no longer appears by default. You can enable it on the command line with the following command: gconftool-2 --type bool --set '/desktop/gnome/interface/show_input_method_menu' true Backwards Compatibility Fedora Core 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: su -c 'yum groupinstall "Legacy Software Development"' Enter the password for the root account when prompted.

Community Package Repository Using the Repository Fedora Extras provides a repository of packages that complement Fedora Core. This volunteer-based community effort is part of the larger Fedora Project. Fedora Extras are Available by Default Fedora systems automatically use both the Fedora Core and Fedora Extras repositories to install and update software. To install software from either the Core or Extras repositories, choose Applications > Add/Remove Software. Enter the root password when prompted. Select the software you require from the list, and choose Apply. Alternatively, you may install software with the yum command-line utility. For example, this command automatically installs the abiword package, and all of the dependencies that are required: su -c 'yum install abiword' Enter the root password when prompted. About Fedora Extras As of the release of Fedora Core 5, there are approximately 2,000 packages in Fedora Extras, built from 1,350 source packages. The following list includes some popular and well-known applications that are maintained by community members in Fedora Extras: ● abiword - elegant word-processing application ● balsa - lightweight e-mail reader ● bash-completion - advanced command-line completion for power users ● bluefish - HTML editor ● clamav - open source anti-virus scanner for servers and desktops ● fuse - tool for attaching non-standard devices and network services as directories ● fwbuilder - graphical utility for building Linux and Cisco firewall rulesets ● gaim-guifications - enhancements to the Gaim Instant Messenger ● gdesklets - widgets for the GNOME desktop ● gnumeric - powerful spreadsheet application ● inkscape - illustration and vector drawing application ● koffice - complete office suite for the KDE desktop ● mail-notification - alerts you as new mail arrives ● mediawiki - the Wikipedia solution for collaborative websites ● nautilus-open-terminal - extension to the GNOME file manager ● pan - the Usenet news reader ● revelation - password management utility ● scribus - desktop publishing (DTP) application ● xfce - lightweight desktop environment ● xmms - the popular audio player ● lots of Perl and Python tools and libraries ● ...and much more! Is your favorite open source application missing from Fedora Extras? Package the application as an RPM, and submit it for review to Fedora Extras. After a successful review, import it to Extras and you can maintain it there. If you don't know how to create RPM packages, there are many other ways to get involved in Fedora Extras and help drive it forward. To learn more about how to use Fedora Extras or how to get involved, refer to http://fedoraproject.org/wiki/Extras. Fedora Legacy - Community Maintenance Project The Fedora Legacy Project is a community-supported open source project to extend the lifecycle of select "maintenance mode" Red Hat Linux and Fedora Core distributions. The Fedora Legacy Project works with the Linux community to provide security and critical bug fix errata packages. This work extends the effective lifetime of older distributions in environments where frequent upgrades are not possible or desirable. For more information about the Fedora Legacy Project, refer to http://fedoraproject.org/wiki/Legacy. Currently the Fedora Legacy Project maintains the following distributions and releases in maintenance mode: ● Red Hat Linux 7.3 and 9 ● Fedora Core 1, 2, and 3 The Fedora Legacy Project will provide updates for these releases as long as there is community interest. When interest is not sustained further, maintenance mode ends with the second test release for the third subsequent Core release. For example, maintenance mode for Fedora Core 4, if not sustained by the community, ends with the release of Fedora Core 7 test2. This provides an effective supported lifetime (Fedora Core plus Fedora Legacy Support) of about 18 months. The Fedora Legacy Project always needs volunteers to perform quality assurance testing on packages waiting to be published as updates. Refer to http:// fedoraproject.org/wiki/Legacy/QATesting for more information. Also visit our issues list at http://www.redhat.com/archives/fedora-legacy-list/2005-August/ msg00079.html for further information and pointers to bugs we have in the queue. If you need help in getting started, visit the project home page on the Wiki at http://fedoraproject.org/wiki/Legacy, or the Mentors page at http:// fedoraproject.org/wiki/Mentors. If you are looking for others ways to participate in Fedora, refer to http://fedoraproject.org/wiki/HelpWanted. CategoryLegacy Fedora Project - Freedom to the Core The goal of the Fedora Project is to work with the Linux community to build a complete, general-purpose operating system exclusively from open source software. Development is done in a public forum. The project produces time-based releases of Fedora Core approximately 2-3 times a year, with a public release schedule available at http://fedora.redhat.com/About/schedule/. The Red Hat engineering team continues to participate in building Fedora Core and invites and encourages more outside participation than was possible in the past. By using this more open process, we hope to provide an operating system more in line with the ideals of free software and more appealing to the open source community. For more information, refer to the Fedora Project website: http://fedora.redhat.com/ 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/HelpWanted for details. This page explains the channels of communication for Fedora users and contributors: http://fedoraproject.org/wiki/Communicate. In addition to the website, the following mailing lists are available: ● fedora-list@redhat.com — For users of Fedora Core releases ● fedora-test-list@redhat.com — For testers of Fedora Core test releases ● fedora-devel-list@redhat.com — For developers, developers, developers ● fedora-docs-list@redhat.com — For participants of the Documentation Project To subscribe to any of these lists, send an email with the word "subscribe" in the subject to -request, where is one of the above list names. Alternately, you can subscribe to Fedora mailing lists through the Web interface: http://www.redhat.com/mailman/listinfo/ 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 (http://www.freenode.net/) for more information. Fedora Project participants frequent the #fedora channel on the Freenode network, whilst 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 will need to register your nickname, or nick. Instructions are given when you /join the channel. IRC Channels Red Hat has no control over the Fedora Project IRC channels or their content. Colophon About the Colophon As we use the term, a colophon: ● recognizes contributors and provides accountability, and ● explains tools and production methods. Contributors ● Andrew Martynov (translator, Russian) ● Anthony Green (beat writer) ● Bob Jensen (beat writer, editor, co-publisher) ● Dave Malcolm (beat writer) ● David Woodhouse (beat writer) ● Francesco Tombolini (translator, Italian) ● Gavin Henry (beat writer) ● Hugo Cisneiros (translator, Brazilian Portuguese) ● Jens Petersen (beat writer) ● Joe Orton (beat writer) ● Josh Bressers (beat writer) ● Karsten Wade (beat writer, editor, co-publisher) ● Luya Tshimbalanga (beat writer) ● Patrick Barnes (beat writer, editor) ● Paul W. Frields (tools, editor) ● Rahul Sundaram (beat writer, editor) ● Sekine Tatsuo (translator, Japanese) ● Steve Dickson (beat writer) ● Stuart Ellis (editor) ● Thomas Graf (beat writer) ● Tommy Reynolds (tools) ● Yoshinari Takaoka (translator, tools) ● Yuan Yijun (translator, Simplified Chinese) 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 Core 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 Core. The publication team also makes them, and subsequent errata, available via the Web.
