Problem:
There was no rescue.img shipped with Red Hat Linux 6.2.
Fix:
Red Hat Linux 6.2 uses a CD-ROM based rescue system, which is full featured and quite handy. To access this rescue system, boot from a installation boot disk (see Making Installation Diskettes for help) or, if your system is able, boot from the first Red Hat Linux installation CD. In either case, use the following boot prompt command:
boot: linux rescue
For information on using the CD-ROM rescue system, see this section of the Reference Guide.
Problem:
If you do a server install with Red Hat Linux 6.2, an X server is not installed for your system.
Fix:
Many systems administrators requested that XFree86 and the X servers not be installed during a Server Class installation. Some servers do not have video capability, or XFree86 is considered a waste of disk space. You will need to manually install the XFree86 packages for your machine if you wish to run X after a Server Class installation.
log in as root
insert the package CD-ROM (CD #1) into CD drive and type the following:
mount /mnt/cdrom
cd /mnt/cdrom/RedHat/RPMS
rpm -Uvh --force X11R6-contrib* XFree86-3.3* XFree86-libs* \
Xconfigurator* fvwm* xinitrc* gtk+-* tcl-* tk-*
If you do not know what your video card is, then run
Xconfigurator and see what RPM it says is not
installed. At which point you will be able to install that
by hand (example:)
rpm -Uvh XFree86-SVGA*
then run Xconfigurator again. This will give you a minimal
X11 install. If you want KDE or GNOME you will need
to install additional packages.
log out as root
Problem:
The functionality of the 'ping' command has changed. This is resulting in many perceived problems with network configuration. The issue at hand is that the simple 'ping' command does a lookup of symbolic names for the host address even if pinging by IP. If you do not have DNS set up and working you will get a lack of response that in times past would not have been present.
Fix:
Start by reading the man page for ping, especially the '-n' option. This will flag ping to not attempt any lookups and will give numeric only output.
