New Packages
2.1. RHEA-2010:0305: freeradius2
A new package, freeradius2, is now available.
FreeRADIUS is an Internet authentication daemon, which implements the RADIUS protocol, as
defined in RFC 2865 (and others). It allows Network Access Servers (NAS boxes) to perform
authentication for dial-up users. There are also RADIUS clients available for Web servers, firewalls,
Unix logins, and more. Using RADIUS allows authentication and authorization for a network to be
centralized, and minimizes the amount of re-configuration which has to be done when adding or
deleting new users.
Red Hat Enterprise Linux 5 originally shipped with FreeRADIUS 1.1.3. Since that time the
FreeRADIUS project has had a major new release: FreeRADIUS 2. Because of the numerous
enhancements available in FreeRADIUS 2 many users would prefer to use the more contemporary
version of FreeRADIUS. This new package, provides this newer version. (

Note: versions 1.x and 2.x of FreeRADIUS are not configuration compatible. Red Hat will continue to
support and make available freeradius-1.1.3. Customers who are utilizing the original freeradius-1.1.3
will see no difference. For customers who wish to utilize the newer 2.x version of FreeRADIUS in Red
Hat Enterprise Linux 5 the new freeradius2 package provides that capability.
Note: freeradius and freeradius2 cannot be installed simultaneously. Because they share common
files, rpm, the Red Hat Enterprise Linux package manager, will prevent an installation of FreeRADIUS
2.x if FreeRADIUS 1.x is already installed. To install freeradius2 on a system with freeradius currently
installed, freeradius must first be uninstalled. See the solution section below for details.
Users wanting to take advantage of the enhancements available in FreeRADIUS 2.x should install and
configure this new package.
2.2. RHEA-2010:0240: gpxe
A new package, gPXE, is now available for Red Hat Enterprise Linux 5.5
gPXE is an open source Preboot Execution Environment (PXE) implementation and bootloader.
Designed to be direct replacement for proprietary PXE ROMs, gPXE also supports additional protocols
such as DNS, HTTP, iSCSI and ATA over Ethernet. gPXE is a significantly restructured update to the
original Etherboot package.
Previously gPXE was available as a separate, and not officially supported, ISO image. As part of
the Red Hat Enterprise Linux 5.5 update, a gPXE package containing ROMs for devices emulated
by QEMU is now available as an integrated and supported Red Hat Enterprise Linux package.

Note: gPXE does not replace etherboot. Both packages, howver, write their .zrom files to the same
directory -- /usr/share/pxe-boot. KVM links to whatever ROM files are present in /usr/share/pxe-boot
