Building a Linux Cluster, Part 3: How To Get Started

Post date: April 25, 2005, 14:04 Category: Network Views: 2641 Comments
Tutorial quote: In the previous two articles in this series, we examined some of the whys and whats of building Linux clusters. This article concludes our series by concentrating on the hows of cluster building. We've seen that a clustered approach to certain computing solutions can save lots of money in hardware and support costs. Now our job is to produce a method of building clusters that's repeatable and predictable—we don't want to give back our hard-won savings in project cost overruns.

Building a Virtual Cluster with Xen

Post date: September 28, 2006, 04:09 Category: Emulation Views: 7548 Comments
Tutorial quote: It is a common practice to have development and test servers for each production server, so that you can experiment with changes without the fear of breaking anything important, but this is usually not feasible with clusters. So how do you try that new version of your favorite program before committing it to the production cluster? A cheap and convenient possibility is to build a virtual cluster.

Thanks to the Xen virtual machine monitor, you can create a number of virtual machines, all running simultaneously in your computer, install different operating systems in them, or just different configurations, and connect them via (virtual) network cards. Xen is a terrific tool for building virtual Beowulf clusters. It can prove useful when learning or teaching about clusters or for testing new features/software without the fear of causing major damage to an existing cluster.

Building A Linux Router

Post date: February 26, 2007, 07:02 Category: Miscellaneous Views: 8119 Comments
Tutorial quote: Building a reliable, full-featured broadband router can be very easy and cost-efficient. This article is about building one for routing a LAN to the Internet with NAT (Network Address Translation -- Linux users also call it as IP Masquerading) using an old computer and a Linux micro-distribution designed to have very low hardware requirements. We'll end up having a very simple and stable system, yet featuring e.g. iptables based stateful firewalling and remote administration.

Enable WPA Wireless access point in Ubuntu

Post date: February 15, 2007, 01:02 Category: Network Views: 4539 Comments
Tutorial quote: I have a Thoshiba laptop at home, I was running “Edgy Eft” (Ubuntu Linux 6.10) But one of the important things about it was its inability to connect to WPA-encrypted Wifi access points.In my home i have a WPA Enabled Wireless router so i need to connect to my wireless network using WPA.I am giving the procedure that worked for me to enable wpa in my toshiba laptop.This will work most of ubuntu users who is trying to access WPA network.

Building a Linux Cluster, Part 1

Post date: April 18, 2005, 03:04 Category: Network Views: 2431 Comments
Tutorial quote: Linux clusters have escaped. As the general popularity of the Linux operating system increases, more complex solutions built with it are becoming increasingly common in the "traditional" (more conservative) IT world. Linux computer clusters, whose provenance was originally universities and research institutions such as the U.S. National Laboratories, are showing up in increasing numbers as high-performance computing solutions within such areas as oil and gas exploration, computer-aided engineering, visualization, and software development. Linux clusters providing highly-available web, mail, and other infrastructure services are also increasingly common. If past computing history is any indicator of future trends, widespread use of Linux clusters in the mainstream IT world cannot be far behind.

How to get ath5k working on Jaunty with Compat-wireless and a self-compiled kernel

Post date: May 27, 2009, 07:05 Category: Software Views: 3277 Comments
Tutorial quote: I used to have some trouble while setting up my Atheros PCI card on Ubuntu Linux 9.04. It worked natively on Ubuntu 8.04, where it was detected as ath0. I upgraded from 8.04 to 8.10 whereby I noticed my wireless PCI card didn’t work natively anymore. Someone suggested me to upgrade from 8.10 to 9.04 Jaunty, and I did that immediately. After the system upgrade I noticed again that my wireless device was gone in Ubuntu 9.04. When I ran iwconfig I didn’t see wlan0 or ath0 anymore.

HowTo: Install configure KVM Virtualization & run Guest OSes in openSUSE

Post date: September 30, 2008, 21:09 Category: Emulation Views: 6017 Comments
Tutorial quote: Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT (vmx) or AMD-V (svm). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Automating Builds on Linux

Post date: April 13, 2005, 00:04 Category: Miscellaneous Views: 2605 Comments
Tutorial quote: An automated nightly build is a process for building an application every night using an infrastructure that automatically executes the required steps at the scheduled time, without any human intervention. A well-planned build process not only builds your application, but also provides you and your team with early detection of incompatible changes in the application components and early detection of errors introduced by newly integrated code. When configured and used properly, automated builds are a critical component for ensuring that the application satisfies quality requirements and continues to run as expected.

Zentyal As A Gateway: The Perfect Setup

Post date: May 26, 2011, 10:05 Category: Installing Views: 5319 Comments
Tutorial quote: Zentyal is a Linux Small Business Server, it lets you manage all your network services through one single platform. It's a Network Gateway, as well as an Infrastructure, UTM (Unified Threat Manager), Office and Communications Server. All these features are fully integrated and easy to configure, it truly helps to save system administrators time. In this tutorial you will see how to set up a Zentyal Server to act as a gateway in a very common scenario. Zentyal will provide basic network infrastructure, load balancing between two Internet providers, firewall and HTTP proxy caching and content filtering.
