Post date: October 1, 2009, 12:10 Category: Miscellaneous Views: 3887 Comments
Tutorial quote: This tutorial shows how you can boot Linux over HTTP with netboot.me. All that users need is Internet connectivity and a small program (gpxe) to boot the machine. This gpxe program provides network booting facility. netboot.me allows you to boot into the following distributions: Debian, Fedora, OpenSUSE, and Ubuntu. netboot.me provides gpxe images for USB sticks, CDs, and also for floppies, i.e., you can boot from a USB sticks, a CD, or a floppy.

Tutorial quote: How To Make Desktop Applications Start Automatically After Login (GNOME)

You probably know this: you power on your machine, and immediately after you have logged in you manually start your two or three favourite applications. Why not have the system start these applications for you automatically? This short guide shows how to accomplish this under GNOME.

Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV)

Post date: October 9, 2005, 18:10 Category: Network Views: 4431 Comments
Tutorial quote: This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

Working with SUSE Linux Enterprise Server 9

Post date: June 22, 2005, 09:06 Category: System Views: 4167 Comments
Tutorial quote: Working with SUSE Linux Enterprise Server (SLES) requires an understanding of the login process, including local account files, system accounts, and managing identities.

Using a console shell or the graphical environment are two possible methods of working on a SLES machine.

Finding your way around a SLES installation requires an in-depth knowledge of the filesystem layout. Essential filesystem components are documented and explained in this chapter. Basic filesystem permissions are also described.

Setting Up A Subversion Repository Using Apache, With Auto Updatable Working Copy

Post date: June 19, 2007, 02:06 Category: Miscellaneous Views: 3727 Comments
Tutorial quote: Subversion is a free/open-source version control system. That is, Subversion manages files and directories over time. A tree of files is placed into a central repository. The repository is much like an ordinary file server, except that it remembers every change ever made to your files and directories. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of time machine.

How To Install VMware Server On A Ubuntu 6.06 LTS (Dapper Drake) System

Post date: July 16, 2006, 16:07 Category: Software Views: 3949 Comments
Tutorial quote: This tutorial provides step-by-step instructions on how to install the free VMware Server (version 1.0.0) on a Ubuntu 6.06 LTS (Dapper Drake) system.

VMware has just released version 1.0.0 of its free VMware Server. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free). In this article we use Ubuntu 6.06 LTS (Dapper Drake) as the host operating system.

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

OpenVZ On Debian Etch For Webservers

Post date: December 26, 2006, 21:12 Category: System Views: 3951 Comments
Tutorial quote: Virtualization is a good practice for servers, since it makes things more secure, scalable, replacable, and replicable, all this at the cost of little added complexity. This guide was written during an install of a Supermicro machine with two dual-core opterons (64-bit), two identical disks (for RAID) and a load of memory. Why OpenVZ and not XEN or the recent KVM kernel module? Well, XEN is not very stable for 64-bit architectures (yet), and it comes with quite a bit of overhead (every VM runs its own kernel) due to its complexity. KVM is very simple but restricts you to run a kernel as one process, so the VM cannot benefit from multi core systems.

Xgl on SUSE 10.1 for Gnome and KDE with NVidia Graphics Cards

Post date: May 12, 2006, 13:05 Category: Desktop Views: 5183 Comments
Tutorial quote: Perhaps the most interesting eye-candy introduced to a mainstream Linux distribution is that of the Xgl 3D desktop environment. Naturally, when seen, it fosters the thought, "How can I do that on my own desktop?" I'll be honest with you, it's not quite as point-and-click as some of the other desktop niceties that we've discussed in the past, such as gdesklets or the gkrellm monitors. That in mind, if you're interested in getting Xgl installed and running on your desktop, you've found the right place. We'll take it a bit at a time and make sure we get you set up. First of all, I need to make sure that you are using this tutorial for a machine running either SUSE Linux 10.1 or SUSE Linux Enterprise Desktop 10, and that you have an NVidia video card. With that, let's get going.

Gnu Queue: Linux Clustering Made Easy

Post date: December 22, 2005, 19:12 Category: System Views: 3639 Comments
Tutorial quote: GNU Queue makes it easy to cluster Linux workstations. If you already know how to control jobs running on your local machine, you already know how to control remote jobs using GNU Queue. You don't even need special privileges to install and run GNU Queue on your cluster--anyone can do it. Once you've discovered how incredibly easy it is to cluster Linux environments with GNU Queue, you'll wonder why organizations continue to spend so much money on comparatively hard-to-cluster Windows NT environments.
