FixedRed Hat Linux 7.1redhat_csaf
Before applying this update, make sure all previously released errata relevant to your system have been applied. To use Red Hat Network to upgrade the kernel, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. Note that you need to select the kernel explicitly if you are using the default configuration of up2date. To install kernel packages manually, use "rpm -ivh <package>" and modify system settings to boot the kernel you have installed. To do this, edit /boot/grub/grub.conf and change the default entry to "default=0" (or, if you have chosen to use LILO as your boot loader, edit /etc/lilo.conf and run lilo) Do not use "rpm -Uvh" as that will remove your running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.

FixedRed Hat Enterprise Linux AS (Advanced Server) version 2.1 redhat_csaf
Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt
