This section outlines those issues that are related to Anaconda (the
Ignalum Linux installation program) and installing Ignalum Linux 9 in
general.
Ignalum Linux 9 now supports graphical FTP and HTTP installations by
default.
Note that graphical FTP and HTTP installations increase memory
requirements by approximately 64MB, due to the necessity of containing
the installer image. However, if you boot the installation program
from CD-ROM 1, no additional RAM will be required; instead the
installer image will be mounted from the CD-ROM.
The firewall configuration screen in the Ignalum Linux installation
program has been simplified. The previous
"High", "Medium", and
"No firewall" settings have been replaced by a
more straightforward on/off-style control. In addition, the default
firewall configuration is now stateful, making it more secure. The
new design also makes it possible for users of NIS authentication,
NFS, and DNS to deploy a firewall with no additional customization
required (although customization by specifying port and protocol is
still possible).
The firewall configuration screen also provides an interface to set up
Internet Connection Sharing functionality (IPv4/v6 Masquerading/NAT).
This is enabled by the use of dhcpd/radvd. By default, ICS will
automatically generate the configuration files needed to run both these
services. This behaviour and more can be adjusted by editing
/etc/sysconfig/ipmasq and /etc/sysconfig/ipv6to4.
NOTE: This change also applies to the Security Level
Configuration Tool
(ignalum-config-securitylevel).
The authentication configuration screen in the Ignalum Linux
installation program now includes more extensive Samba-LDAP
configuration as well as Winbind support. There is also an option to
set Kerberos5 for use in Samba for joining an ADS realm.
NOTE: This change also applies to the Authentication Configuration Tool
(authconfig-gtk).
The network configuration screen in the Ignalum Linux installation
program now includes WINS configuration. This is only useful when
configuring Samba to interoperate with Windows servers/clients. If the
Primary WINS field is left blank, Samba will be configured to run as a
WINS server for NetBIOS name resolution.
NOTE: This change also applies to the Network Configuration Tool
(ignalum-config-network).
JFS, XFS and Reiserfs support is now built-in to the Ignalum Linux Installer.
This section describes post-installation issues.
The Security Level Configuration Tool

left blank, Samba will be configured to run as a WINS server for
NetBIOS name resolution.
NOTE: This change also affects the Ignalum Linux installation program.
NOTE: Issues resulting from PEERDNS being inappropriately disabled by
redhat-config-network is fixed in the ignalum-config-network tool.
The Samba Configuration Tool (ignalum-config-samba) now includes a
dialog window for joining a domain as well as one for implanting your
winbind credentials used by winbindd during session set-up to a domain
controller.
NOTE: This tool can also be launched from the Firstboot utility
(firstboot) under the "User Account" setup module.
Samba smb.conf changes:

ldap add dn New
- ldap add dn – used to migrate user accounts, groups, and computer
accounts created with the passwd/smbpasswd or 'net user add' command to
the Samba-LDAP database server on the fly. On user/password creation,
Samba will automatically create posixAccount and shadowAccount
objectclasses and attributes for the user.Ignalum Linux 9 now includes the Nvidia Accelerated Linux Driver Set.
Please refer to the documentation provided in
/usr/share/doc/nvidia-glx-*/ for more information.
Ignalum Linux 9 includes IPv6 support out of the box and is now
switched on by default during the post installation phase of the
installer. IPv6 support can be disabled by editing the file
/etc/sysconfig/network and removing the following two lines:
NETWORKING_IPV6=yes
IPV6INIT=yes
Please refer to the documentation relating to IPv6 support provided in
/usr/share/doc/initscripts-*/.
The LDAP Directory Manager (directory_administrator) now shipped with
Ignalum Linux includes built-in Samba3 support.
Ignalum Linux 9 now includes the Macromedia Flash Player, Adobe Acrobat
Reader and Sun Java(tm) 2 Runtime Environment including plug-ins for
the Mozilla web browser.
aeEngine Demo-Related Notes – The aeEngine-TestSdl package includes the
source code + precompiled binary of the TestSdl demo. This demo installs
to /usr/src/AE/TestSdl and makes use of the various plugins found within
the `Plugins' directory. However both the FreeImagePlugin and
DevILPlugin included with TestSdl cannot be loaded simultaneously. This
means for TestSdl to work properly, you can only have one of them stored
in the plugins directory at any one time (either FreeImagePlugin or
DevILPlugin; the latter is preferred though).
To run the demo:
1. `cd' into the /usr/src/AE/TestSdl directory.
2. Type `make' to compile the package.
3. Type `./run.sh' to execute the demo.
NOTE: Your video card must support vertex buffers, otherwise you’ll
receive the following runtime error:
TestSdl: glprocs.c:12352: InitGenBuffersARB: Assertion `0' failed.
./run.sh: line 4: 4002 Aborted ./TestSdl
The Firstboot utility (firstboot) now has the ability to create LDAP
accounts for Samba. An LDAP user account is created via the User Account
module which will launch a dialog window for doing this only if an LDAP
server is found. In order for this to work you must enable LDAP by first
clicking the Use Network Login button which will launch the
Authentication Configuration Tool (authconfig-gtk). You can use this
tool to configure LDAP authentication.
Ignalum Linux 9.2 now includes the ATI proprietary driver for ATI Radeon graphic cards.
Please refer to the documentation provided in
/usr/share/doc/ati-fglrx-*/ for more information.
Ignalum Linux 9.2 now includes the NVIDIA Linux drivers for nForce chipsets.
Please refer to the documentation provided in
/usr/share/doc/nvidia-nforce-*/ for more information.
The following information represents the minimum hardware requirements necessary to successfully install Ignalum Linux 9.2:
NOTE: The following CPU specifications are stated in terms of Intel processors. Other processors (notably, offerings from AMD, Cyrix, and VIA) that are compatible with and equivalent to the following Intel processors may also be used with Ignalum Linux.
