This article describes how to build a Local Area Network (LAN) consisting of two or more computers running the Red Hat Linux operating system. The article begins with the basics: an overview of the TCP/IP (Transmission Control Protocol/Internet protocol) suite, and an explanation of assigning IP addresses in a LAN. Then the article covers the LAN hardware and configuration using a tool called LinuxConf in the Red Hat Linux operating system environment. Lastly, the article walks you through the critical steps of testing and troubleshooting your LAN.

Want to get an idea of what speed advantage adding an expensive hardware RAID card to your new server is likely to give you? You can benchmark the performance difference between running a RAID using the Linux kernel software RAID and a hardware RAID card. My own tests of the two alternatives yielded some interesting results.

A run-level is a system state that is defined by the services listed in /etc/rc.d. Typically, advanced administration of a machine is done by switching run-levels (or state) to perform tasks such as minimal resource usage, run-level 3, shutdown run-level 0, or maintenance. Maintenance is run-level 1–or single user mode, as it is commonly known

Everybody who owns a computer will someday need to dispose of a disk drive. Before you do, it is a good idea to cleanse the drive, so no one can read your sensitive information. Deleting files and reformatting is not sufficient; determined effort can still reveal data from a drive even after it appears to be gone. To do a more thorough job, I suggest using wipe.
You need to take special pains because files that are “deleted” are not really gone. Most operating systems, including Linux and its ext2 filesystem, just delete the pointer to a deleted file; the data still exists on the drive. It is not effectively removed until every bit of the space it was occupying on the drive has been overwritten. Even then there are ways, albeit difficult, to analyze the drive and extract data. The only way, short of melting the drive, to ensure the data is gone for good is to overwrite the drive several times with random data.

The storage capacity and data retrieval speeds of Hard Disks have increased multiple folds in last few years. However for large business organizations, which not only need to store terabytes of invaluable data but access them frequently as well. These organizations cannot afford to let their systems go offline even for a short duration of time. Moreover they cannot even think of loosing even small amount of data due to disk failure or for that matter any other reason.

A hard disk is usually subdivided into one or more partitions. These partitions are normally not re-sizable (making one larger and the adjacent one smaller) The purpose of GParted is to allow the individual to take a hard disk and change the partition organization therein, while preserving the partition contents.
GParted is an industrial-strength package for creating, destroying, resizing, moving, checking and copying partitions, and the filesystems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks and mirroring one partition with another (disk imaging).
LiveCD and LiveUSB versions available

Want to run Linux any time, any place? Here’s what to do with popular distributions like Puppy Linux, Ubuntu, and Fedora, so you can boot up directly from your thumb drive.
Most of the time, Linux is run from either an installation on a hard drive or a live CD/DVD distribution. The first is fast, but not very portable; the second can be run anywhere you have a computer and a CD drive with boot access, but typically isn’t very fast. Over the last few years, though, we’ve seen the emergence of something that combines the speed of a hard drive install with the convenience of a live CD: running Linux from a USB flash drive.

It’s a given that all disks eventually die, and it’s easy to see why. The platters in a modern disk drive rotate more than a hundred times per second, maintaining submicron tolerances between the disk heads and the magnetic media that store data. Often they run 24/7 in dusty, overheated environments, thrashing on heavily loaded or poorly managed machines. So, it’s not surprising that experienced users are all too familiar with the symptoms of a dying disk. Strange things start happening. Inscrutable kernel error messages cover the console and then the system becomes unstable and locks up. Often, entire days are lost repeating recent work, re-installing the OS and trying to recover data. Even if you have a recent backup, sudden disk failure is a minor catastrophe.

Last week we covered what Linux software RAID is good for and not good for, and hardware RAID vs. software RAID. In a nutshell it’s about getting good performance for just the cost of ordinary inexpensive drives and controllers, and either increasing uptimes or speeding up performance, or a bit of both. It is not a substitute for the usual sensible failsafes like regular backups, power protection, and terrorizing users into following … I mean “enforcing sane security policies.”
