The project consists of the following: a lightly modified X server. By installing these components, you can have GL-accelerated effects on your desktop with very few changes, as well as the ability to enable and disable them at will without replacing your X server.
The goal of the frysk project is to create an intelligent, distributed, always-on system monitoring and debugging tool that allows developers and system administrators to: monitor running processes and threads including creation and destruction events.
In Red Hat Enterprise Linux 5 the frysk graphical user interface is a technology preview, whereas the frysk command line interface is fully supported. Systemtap provides free software GPL infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem.
With the help of systemtap , developers no longer need to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data.
Dogtail is a GUI test tool and automation framework written in Python that uses Accessibility technologies to communicate with desktop applications. Red Hat Enterprise Linux 5 also features support for the following languages as technology preview: Assamese. For more information about how to install and enable support for these languages, refer to the Internationalization section of this document. Anaconda now has the capability to detect, create, and install to dm-multipath devices.
To enable this feature, add the parameter mpath to the kernel boot line. Note that the parameter mpath may cause a boot failure if a device's major:minor number changes.
This issue will be addressed in a future update of Red Hat Enterprise Linux 5. Anaconda now provides the ability to install to an iSCSI device. Booting and installing is fully supported with the QLogic qla4xxx hardware initiator. However, the capability to install to an iSCSI device for the open-iscsi software initiator is currently considered a Technology Preview, due to the following issues:.
Text mode installation does not complete. You must do a graphical install, or an automated kickstart install. Media-based installations do not complete. You must do a network-based install. When this occurs, use the installer shell to configure the storage through iSCSI commands.
The iscsid daemon may not properly start. To confirm that the iscsid daemon is running, run the command iscsiadm -m session -i and check that the line, Internal iscsid Session State: reports a value it can be any value. On certain iSCSI target implementations, the system may hang during shutdown. On certain iSCSI target implementations, the system may hang during reboot. To avoid this, shutdown the system and boot it up again instead of rebooting directly from a session.
While installation on an iSCSI device may appear to succeed, the resulting installation will not boot properly. On the first boot after install, you may receive SELinux errors such as the following:.
Once the system has properly booted, use the command setenforce 1 to restore enforcing mode. These limitations will be addressed in a future Red Hat Enterprise Linux 5 update. Known Issues. To do this, perform the following steps:. Enter the Adapter settings menu. If the adapter is incorrectly set to "I2O" emulation, the system will attempt to load the i2o driver.
This will fail, and prevent the proper driver from being loaded. Regardless of this, the hardware should always be set to "Mass Storage" emulation mode when used with Linux. Red Hat Enterprise Linux 5 includes openmpi This happens after the openmpi stack works as expected for a varying amount of time.
Installing Windows Server as a guest on a fully virtualized Red Hat Enterprise Linux 5 system ends unexpectedly after completing the first stage of installation. When this happens, the graphical console window closes, and the guest disappears from the Virtual Machine Manager 's list of machines, resulting in a Broken pipe error.
This issue will be resolved in an upcoming Red Hat Enterprise Linux 5 update. To work around this, use the following command at the terminal:. As such, the disk line should now read as follows:.
Due to the current inability of the Virtualization feature to asynchronously release grant table operations, it is unsafe to unload the xennet module in guests. In such situations, grant tables are used to perform backend-frontend communication, and there is no guarantee that the backend will release the references, leading to an inevitable memory leak. This issue will be resolved in the next minor release of Red Hat Enterprise Linux 5.
At present, users are advised not to unload the xennet module in guests. Running ethtool eth0 outputs incomplete information about the ethernet card settings. This only occurs in systems running a virtualized kernel, since the Virtualization feature uses a networking setup where the physical ethernet device is identified as peth0. As such, the correct command for retrieving information about the physical ethernet device is ethtool peth0. Installing the Virtualization feature may cause a time went backwards warning on HP systems with model numbers xw and xw Note that this option is not available on xw machines.
When using Red Hat Enterprise Linux 5 on a machine with an nVidia CK chipset installed, you may receive kernel messages similar to the following:. Further, these messages do not, in any way, affect the operation of the machine.
This is caused by a Cisco Aironet Wireless device firmware limitation. Laptops that have the Cisco Aironet MPI wireless card equipped may hang trying to get a DHCP address during any network-based installation using the wired ethernet port. To work around this, use local media for your installation.
Alternatively, you can disable the wireless card in the laptop BIOS prior to installation you can re-enable the wireless card after completing the installation. Currently, system-config-kickstart does not support package selection and deselection.
When using system-config-kickstart , the Package Selection option indicates that it is disabled. This is because system-config-kickstart uses yum to gather group information, but is unable to configure yum to connect to Red Hat Network. This issue is currently being investigated for resolution by the next minor release of Red Hat Enterprise Linux 5.
At present, you need to update package sections in your kickstart files manually. When using system-config-kickstart to open a kickstart file, it will preserve all package information in it and write it back out when you save. Systems with SATA controllers may pause during the boot process, displaying the following error message:. Note that after the second error message, the system will continue the normal boot process.
Other than the delay, there is no impact to the system; as long as the SATA drives are physically present they will still be detected properly. Systems should be configured with memory in node 0 to prevent the kernel panic. Installing to LVM mirror devices through Anaconda is currently not supported. This capability will be added in a future update of Red Hat Enterprise Linux 5. The presence of such directories results in the error stated above.
To prevent this error, unpack trees only to directories other than the one containing the installation ISO images. An equivalent functionality will be added in a future update of Red Hat Enterprise Linux 5. Neither kexec nor kdump are able to dump onto disks attached to an accraid controller.

And while it's certainly no excuse with the amount of threads we mods see on a daily basis next time it would be more efficient to handle questions like this using the "report" button or e-mailing one of this forums mods. The truth as I got it from Redhat: You can download and run Redhat without ever paying them. You can use a 30 day evaluation to download the latest updates.
After the 30 days, you may download the source RPMs for updates and compile them yourself. You only have to pay if you want Redhat to provide updates via the up2date or yum package managers or if you require support. There are two packages in Redhat that are copy write protected: redhat-logos and one other that I am not sure of. This information is as I was told in my RH class very recently.
