HOWTO backup your linux system using bash, tar and netcat

Post date: April 2, 2006, 22:04 Category: System Views: 2717 Comments
Tutorial quote: I recently ran into the problem of not having enough hard drive space on my slackware linux laptop, but was lucky enough to have a much bigger drive sitting around from before and wanted a way to perform a hassle free seamless upgrade. i had this idea and it worked pretty well so i thought i would share it since i think it's pretty cool and only requires the use of two tools that should be included with all distributions.

Windows Linux DualBoot Tutorial

Post date: April 1, 2006, 05:04 Category: Installing Views: 2568 Comments
Tutorial quote: This tutorial was written to help set up a dual boot on a SATA drive but it will also work for PATA so continue forward and I will let you know if you need to skip something. In order to have a fully functional dual boot system it is preferred that Windows be loaded first. After that you can load Linux and easily dump the boot configuration on Windows NTLDR file (comparable to Linux boot file).

Configuring Apache for Maximum Performance

Post date: April 1, 2006, 03:04 Category: Optimizing Views: 4279 Comments
Tutorial quote: Apache server performance can be improved by adding additional hardware resources such as RAM, faster CPU etc. But, most of the time, the same result can be achieved by custom configuration of the server. This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on the Linux systems.

Network Monitoring with Zabbix

Post date: March 31, 2006, 21:03 Category: Software Views: 5138 Comments
Tutorial quote: ZABBIX is software that monitors numerous parameters of a network and the health and integrity of servers. ZABBIX uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. ZABBIX offers excellent reporting and data visualisation features based on the stored data. This makes ZABBIX ideal for capacity planning.

Xen Virtualization and Linux Clustering, Part 2

Post date: January 21, 2006, 06:01 Category: System Views: 2962 Comments
Tutorial quote: We ended last time after configuring our first unprivileged Xen domain. In this article, we complete our cluster and then test it using an open-source parallel ray tracer. The first thing we need to do is create additional slave nodes to be used with the cluster. So, let's get down to business.

Xen Virtualization and Linux Clustering, Part 1

Post date: January 21, 2006, 06:01 Category: System Views: 3649 Comments
Tutorial quote: Have you heard about Xen virtualization and want to get some hands-on experience? Do you want to experiment with Linux clustering but only have a single computer to devote to the cause? If you answered yes to either of these questions, keep reading.

In this article, I briefly introduce the concepts of Xen virtualization and Linux clustering. From there, I show you how to set up multiple operating systems on a single computer using Xen and how to configure them for use with clustering. I should point out that a cluster implemented in this manner does not provide the computational power of multiple physical computers. It does, however, offer a way to prototype a cluster as well as provide a cost-effective development environment for cluster-based software. Even if you're not interested in clustering, this article gives you hands-on experience using Xen virtualization.

Benchmarking Filesystems Part II

Post date: January 6, 2006, 22:01 Category: Benchmarks Views: 4672 Comments
Tutorial quote: After the last article was published, I have received more than a dozen requests for a second filesystem benchmark using the 2.6 kernel. Since that time, I have converted entirely to XFS for every Linux machine I use, so I may be a bit bias regarding the XFS filesystem. I tried to keep the hardware roughly the same. Instead of a Western Digital 250GB and Promise ATA/100 controller, I am now am using a Seagate 400GB and Maxtor ATA/133 Promise controller. The physical machine remains the same, there is an additional 664MB of swap and I am now running Debian Etch. In the previous article, I was running Slackware 9.1 with custom compiled filesystem utilities. I've added a small section in the beginning that shows the filesystem creation and mount time, I've also added a graph showing these new benchmarks. After the first round of benchmarks, I received a sleuth of e-mails asking for the raw numbers. The numbers are now included in tables at the end of this e-mail for both the last and current set of benchmarks.
