3-D Support for nVidia Graphics Cards

The RPM packages NVIDIA_GLX and NVIDIA_kernel for the nVidia driver with 3-D support are no longer available. To install the nVidia driver, use the nVidia driver patch in YOU (YaST Online Update). The drivers for 2-D support are still included in SLES.

Removable Media / subfs

Removable media are now integrated via subfs. It is not necessary to mount the media manually. A cd /media/* triggers the automatic mounting. Note that media cannot be ejected while a program is accessing them.

VMware Installation

If you install within VMware, you should disable acceleration in VMware: Edit-> Virtual Machine Settings -> Options -> Advanced -> Disable acceleration.

Lustre Clustering File System Support

We have included Lustre as the cluster-capable file system of our choice. For Novell support offerings regarding Lustre, go to http://www.suse.com/feedback.

Globus Toolkit 2.0

The Globus Toolkit 2.0 was part of SUSE LINUX Enterprise Server (SLES) 8. Because of major changes in the Globus TK API and in binaries, we have decided to exclude Globus Toolkit 2.x or 3.x in SLES 9. Support for the Globus Toolkit is available through a consulting agreement. Go to http://www.suse.com/feedback for available offerings.

CIFS

The CIFS shipped together with Samba is currently not supported. The current implementation is not stable enough to work in a production environment.

Update

Network Device Setup

The network device setup has been changed. Previously the configuration of a nonexisting interface triggered initialization of the hardware. Now new hardware is searched for and initialized first, which then triggers the setup of the new network interface.

Additionally, new names are introduced for the configuration files. Because the name of a network interface is created dynamically and the use of Hot Plug devices contnues to increase, a name like ethX is no longer usable for configuration. We now use unique descriptions like the MACaddress or the PCI slot for naming interface configurations.

Note: You can use interface names when they are present. For example, ifup eth0 / ifdown eth0 still works.

The configuration for devices is found in /etc/sysconfig/hardware. The interfaces these devices provide are in /etc/sysconfig/network.

An extended Readme is available under /usr/share/doc/packages/sysconfig/README.

Sound Configuration

After an update from an older distribution, the sound cards must be reconfigured with the sound module of YaST2. Invoke YaST as user root using the command yast2 sound.

Non-UTF-8 Filenames

Files on file systems created by SLES 9.0 and older distributions use (when not set otherwise) non-UTF-8 encoding for their filenames. If these filenames contain non-ASCII characters, they will be garbled on SLES 9 and later versions. A fix is to use the convmv script which changes the encoding of the files to UTF-8.

XML Stylesheets and DTDs

The FHS now requires XML resources (DTDs, stylesheets, etc.) to be installed in /usr/share/xml. Therefore, some directories are no longer available in /usr/share/sgml. If you encounter problems, modify your scripts or makefiles or use the official catalogs (especially /etc/xml/catalog or /etc/sgml/catalog).

Codepage with Mounting VFAT Partitions

When mounting VFAT partitions, the parameter formerly called code= must be changed to codepage=. If mounting a VFAT partition causes problems, check if the file /etc/fstab contains the old name for the parameter.

Apache 1.3 Replaced by Apache 2

The Apache Web server (version 1.3) has been replaced by Apache2 (version 2.0.49). A system update on a machine with an HTTP server installation will remove the Apache package. Install apache2 and you will need to adapt your setup manually; there is no automated facility avaialble.

Configuration files that were in /etc/httpd are now in /etc/apache2. Apache2 requires either package: apache2-prefork (recommended for stability) or apache2-worker.

During updates, there might be some conflicts requiring manual attention.

Known issues:

Using SAMBA with LDAP

If you used Samba on SLES 8 with SAMBA_SAM set to LDAP in /etc/sysconfig/samba, you must migrate your Samba LDAP configuration to the new Samba 3 LDAP schema included in SLES 9. You can find additional information migrating your Samba LDAP configuration at http://www.suse.com/sles/documentation/samba/.

Raw Devices

There have been significant changes in the implementation of raw devices. For more details, see /usr/share/doc/packages/util-linux/README.raw, which is provided in the util-linux package.

Installation

Some Systems Might not Install with Default Settings.

First try the Installation - ACPI Disabled option. Second, try the "Installation - Safe Settings" option.

Please report these cases via http://www.suse.com/feedback.

Installing with an FTP Server

If you use an FTP Server to provide the CDs for installation, there is a restriction for the path you specify during the installation. Currently you can specify only relative paths. That means that every path specified starts at the login directory of the FTP Server. There is no difference whether you use personal or anonymous login.

Same CD Requested Twice

Some CDs have to be inserted twice during the installation process. Install via network or hard disk to avoid this issue.

PCI Hot Plug

To support real PCI Hot Plug, the acpiphp kernel module needs to be loaded by the pci.rc script. You can enable this by setting the sysconfig variable HOTPLUG_DO_REAL_PCI_HOTPLUG=yes.

Setting Up an Installation Server for Network Installations

To set up an installation server for installations via NFS/FTP/HTTP, the CDs have to be copied into a special directory structure.

Go to a directory of your choice and execute the following commands:

mkdir -p installroot/sles9/CD1

Copy the contents of SLES CD1 to this directory.

mkdir -p installroot/core9/CD1

Copy the contents of SLES CD2 to this directory

mkdir -p installroot/core9/CD2

Copy the contents of SLES CD3 to this directory

mkdir -p installroot/core9/CD3

Copy the contents of SLES CD4 to this directory

mkdir -p installroot/core9/CD4

Copy the contents of SLES CD5 to this directory

mkdir -p installroot/core9/CD5

Copy the contents of SLES CD6 to this directory

ln -s sles9/CD1/boot boot

ln -s sles9/CD1/content content

ln -s sles9/CD1/control.xml control.xml

ln -s sles9/CD1/media.1 media.1

mkdir -p installroot/yast

echo "/sles9/CD1 /sles9/CD1\n/core9/CD1 /core9/CD1" > yast/instorder

echo "/sles9/CD1 /sles9/CD1\n/core9/CD1 /core9/CD1" > yast/order

If you are now asked for the installation directory specify

installroot.

If you want to set up an MS Windows system as an install server, go to the directory dosutils/install. There is a script install.bat that will create the structure and ask you for the CDs. There are also the files instorder and order that have to be copied to the directory \suseinstall\yast. Before you copy the order file, replace the variables UserAccount, PASSword and IP-Number with the respective Values of your MS Windows machine. During the installation process, you need to specify the only share suseinstall.

Problems with "xhost +" to display remote X sessions on your local screen

This is relevant only if you control an installation over a network and want to display your remote X or YaST session on your local display. On some Linux/UNIX systems, it is no longer sufficent to enter the command "xhost +" to grant access to the local X-Server. For security, the X-Server should no longer listen on port 6000. To verify whether the X-Server still listens on port 6000 enter the command:

netstat -an | grep 6000

If the line

tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN

does not show up, the server is not listening.

Adding Storage Drivers after Initial Installation

During installation, all blockdevice drivers for storage controllers are added to an "initial RAMdisk". This ensures accessibility for attached storage at all times.

Adding such a controller (with attached storage) will initially work as expected because of the new hot/coldplug capabilities, but may not function properly later on.

To ensure system integrity at all times, we recommend following YaST2 standards, adding the appropriate module to INITRD_MODULES in /etc/sysconfig/kernel, then running /sbin/mkinitrd again.

Multipathing with MD Devices

To upgrade MD multipathing from SLES 8 to SLES 9, start the system with the kernel parameter "barrier=off".
YaST will then offer the MD device for update.

Multipathing with LVM1

During update, the multipathing volumes are recognized only as standard LVM volumes.

We recommend using EVMS, which will recognize LVM1 multipathing.

Updates and Features

Updated Core System with Latest Versions/Features of all Packages

New and Improved YAST (Our Installation and Administration Tool)

Next-Generation 2.6.5 Linux Kernel with Many Improvements over 2.4 Kernels

Improved HA Support

Fully Enabled and Supported UTF-8

Ready for the Asian Market (Including Translations and Commercial Fonts)

Red Carpet Enterprise Daemon

SLES 9 includes the Red Carpet daemon. To install the Red Carpet Daemon, execute the following command: /usr/sbin/inst-rcd.

New Type of Installation Source: SLP

New feature: linuxrc understands a new installation source, SLP. If you select install=slp at the bootloader prompt, linuxrc will send an SLP (Service Location Protocol) request for service install.suse to the network and prompt you to select an entry from the list of returned URLs. See R C 2608 and http://www.openslp.com for more information on SLP.

OpenSSH Updated to Version 3.8

The gssapi support has been replaced with gssapi-with-mic to fix possible MITM (man-in-the-middle) attacks. These two versions are not compatible. This means that you cannot authenticate from older distributions by Kerberos tickets because different methods for authentication are used.

libiodbc Has Been Dropped

If you use FreeRADIUS, you must now link against unixODBC.

Change in Resolver Library

Incompatible change: the resolver library treats the .local top level domain as a link-local domain and sends multicast DNS requests instead of normal DNS requests to the multicast address 224.0.0.251 port 5353. If you already use the .local domain in your name server configuration, you will have to switch to another domain name. See http://www.multicastdns.org for more information on multicast DNS.

Wireless LAN Cards

Some wireless LAN cards (PrismGT, Centrino, Atmel, ACX100) need firmware to operate. Due to licensing issues, we can't ship these firmware binaries. Read /usr/share/doc/packages/wireless-tools/README.firmware for information on how to obtain and install the firmware.

Support for Intel PRO/Wireless 2100 (a.k.a. Centrino)

There is now experimental support for Intel Centrino WLAN adapters. The driver is not complete; WEP support and operation modes other than managed mode are missing.

SSH and Terminal Applications

When using remote access (notably SSH, Telnet, and RSH) between SUSE LINUX 9.1 / SLES 9(in its default configuration with UTF-8 enabled) and older systems (9.0 and earlier, where UTF-8 is not enabled by default or not supported), terminal applications might display garbled characters.

This is because OpenSSH does not forward locale settings, so system defaults are used which might not match the remote terminal settings. This affects text mode YaST and applications run remotely as non-root user. The applications run as root are affected only when users change the default locales for root (only LC_CTYPE is set by default).

POSIX-Compliant, High-Performance Threads Support (NPTL)

SUSE LINUX 9.1 / SLES 9 features a new pthread implementation called NPTL, which is faster and better than the old implementation called linuxthreads.

If your old program is incompatible with this new threading implementation, we also provide the old one. To switch to the old version, set the environment variable LD_ASSUME_KERNEL to 2.4.21 by using export LD_ASSUME_KERNEL=2.4.21 in Bash.

Applications Using ncurses

If problems occur with ncurses-based applications running on the text console, simply issuing unicode_stop (reverting keyboard and console from Unicode mode) usually provides a fix.

SuSEplugger

SuSEplugger now supports drive notifications and, therefore, does not poll the devices. Drives that fail to support notification might not react. A workaround is to enable polling to get back the old behavior.

Printer Configuration

For information about the changes with printing, go to http://portal.suse.com/sdb/en/2004/03/jsmeix_print-einrichten-91.html

modules.conf / modprobe.conf

Parameters for loadable modules have now to be placed in modprobe.conf.
