How do I get Linux to recognize more than 64MB of RAM? I presume I may need to tune the kernel. How do I do this? —Edward Longstrom
The reason Linux does not recognize more than 64MB of RAM is actually related to limitations in BIOS. You can force the issue from LILO with an argument of mem=??M, where ?? is the amount of physical RAM in the machine and M stands for Megabytes. To make this automatic, add that line to the block defining the specifics for each boot (image) configuration. —Dan Lark, SuperNet of Las Cruces, Inc dan@netsteps.com
I have a Toshiba XM-series CD-ROM that is not recognized by the kernel. I thought it was a standard IDE/ATAPI drive. What could be causing this? —Scott Herscher
First, make sure your CD-ROM is connected to a primary or secondary IDE interface. Kernel 1.2.13 will not see tertiary interfaces. Then you may need to give it command line parameters to have the kernel find it. Here is a chart:Primary Interface - Master: hdaPrimary Interface - Slave: hdbSecondary Interface - Master: hdcSecondary Interface - Slave: hddUse the “hd” parameter for your actual device, based on the chart above, to boot with a command like:
LILO boot: linux hdd=cdrom
If you don't know how the CD-ROM is connected, it is safe to try them all. You can then add this as an append line to your lilo.conf. An example would be:
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image=/boot/vmlinuz-2.0.12
label=linux
root=/dev/hda2
read-only
append="hdd=cdrom"
Make sure to run /sbin/lilo after editing the file. —Donnie Barnes, Red Hat Software redhat@redhat.com
Are there any FAQs about setting up Netscape 2.02 with Linux? After you unzip Netscape where do you put the files? When I set up Netscape 2.02 it gives me the error message cannot find lib.so.4. Any ideas? —Marc A. Krushelnyski
First of all, I recommend using 3.0. You can get an ELF version that won't take up nearly as much memory and won't cause the missing library problem you mention. Second, the README that comes with Netscape tells you where to put the files. I'd put the Netscape binary in /usr/local/bin, then put the zip file in the recommended location. —Donnie Barnes, Red Hat Software redhat@redhat.com
I installed PPP support from the control panel, but when I want to access the pppd in /usr/sbin I get the message THERE IS NO PPP SUPPORT IN THIS SYSTEM. I tried to install ppp-2.2.0f.tar.gz to see if that would help, but it didn't. I checked the /proc/net/dev file with a cat command but all I saw was a column of:
s1 s2 s3
and so on with many zeros. What must be done to correct this problem? —Dominik Barth
You either didn't install ppp-2.2.0f properly, or you didn't compile PPP support into the kernel. A standard distribution kernel should have PPP compiled in, so I would guess your pppd install went wrong.Most likely, you either didn't make install, didn't do make install as root, or your old pppd binaries live in a different place from your new pppd binaries and the path for the old binaries comes before the newer one in your PATH environment variable. —Bert Vermeulen bert@cnct.com
Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

Free Webinar: Linux Backup and Recovery
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
