SuSe Xgl on SUSE 10.1 for Gnome and KDE with NVidia Graphics Cards
Post date: May 12, 2006, 09:05 Category: Desktop Views: 6
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.
Linux Bandwidth monitoring with iptables
Post date: December 27, 2005, 10:12 Category: Network Views: 63
Tutorial quote: Linux has a number of useful bandwidth monitoring and management programs. A quick search on Freshmeat.net for bandwidth returns a number of applications. However, if all you need is a basic overview of your total bandwidth usage, iptables is all you really need -- and it's already installed if you're using a Linux distribution based on the 2.4.x or 2.6.x kernels.
RedHat Creating desktop profiles with Sabayon
Post date: July 18, 2005, 18:07 Category: Desktop Views: 101
Tutorial quote: Instead of creating a new desktop setup every single time a new user comes along, it would be much easier to create some templates. If only there were an easy way to make and manage these templates.

Fortunately, we are not the first to ponder this issue. The creators of Sabayon decided to tackle the lack of a good desktop setting management tool. With Sabayon, they created an application that handles these problems and more.
SuSe How to set up smart package manager on SUSE LINUX 10.0
Post date: October 29, 2005, 20:10 Category: System Views: 142
Tutorial quote: Quote from the tutorial: The advantage of smartpm is, that, besides the ability to use mirrors it is able to use different repository structures. So I was able to use the apt-repository structure which provides more channels then the actual yum structure [...], and so I was able to build up a package management with update channels which is capable of using and choosing mirrors in a similar way as yum is.
Debian Monitoring Services using Mon
Post date: April 4, 2006, 16:04 Category: Installing Views: 16
Tutorial quote: mon is a general-purpose scheduler and alert management tool used for monitoring service availability and triggering alerts upon failure detection. mon was designed to be open and extensible in the sense that it supports arbitrary monitoring facilities and alert methods via a common interface, all of which are easily implemented with programs in C, Perl, shell, etc., SNMP traps, and special mon traps.
Unix+clones Remote backup using ssh, tar and cron
Post date: April 12, 2005, 21:04 Category: Miscellaneous Views: 51
Tutorial quote: Are you looking for a solution to backup your data to a remote location? While a solid backup solution such as Arkeia or TSM from IBM are nice from an enterprise point of view, simpler solutions are available from a home user's perspective. I will walk you through on you how you can backup your data to a remote server, using the default tools available on all linux systems. In a nutshell, we will use ssh capabilities to allow a cron job to transfer a tarball from you local machine to a remote machine.

For the purpose of this tutorial, the local machine will be called “localmachine” (running slackware) and the remote server will be called “remoteserver” (slackware as well). The user will be joe (me). You will have to substitute those 3 with your own machines names and user.
Linux Monitoring and Managing Linux Software RAID
Post date: April 15, 2005, 19:04 Category: System Views: 56
Tutorial quote: Systems administrators managing a data center face numerous challenges to achieve required availability and uptime. Two of the main challenges are shrinking budgets (for hardware, software, and staffing) and short deadlines in which to deliver solutions. The Linux community has developed kernel support for software RAID (Redundant Array of Inexpensive Disks) to help meet those challenges. Software RAID, properly implemented, can eliminate system downtime caused by disk drive errors. The source code to the Linux kernel, the RAID modules, and the raidtools package are available at minimal cost under the GNU Public License. The interface is well documented and comprehensible to a moderately experienced Linux systems administrator.

In this article, I'll provide an overview of the software RAID implementation in the Linux 2.4.X kernel. I will describe the creation and activation of software RAID devices as well as the management of active RAID devices. Finally, I will discuss some procedures for recovering from a failed disk unit.
FreeBSD Building a FreeBSD Build System
Post date: April 14, 2006, 20:04 Category: System Views: 24
Tutorial quote: When you finish this article, you will have an unbeatable update system. Even mergemaster will work faster. You will have an update system in which a machine update/upgrade will take less than 10 minutes.
SuSe Setting up yum on SUSE LINUX 10.0
Post date: October 16, 2005, 12:10 Category: System Views: 219
Tutorial quote: Why should I use yum and not yast? Well, yast is nice, but has some disadvantages: It can#t check for gpg keys, you have to trust the mirrors you add. And, speaking about mirrors, yast has no real mirror management for one source. Especially in these times the most and best known SUSE mirrors are very slow or just closed down, so you have to add other sources in yast. But yast needs your clicks when a mirror is not reachable, and if you enter several sources just as mirrors, it checks every single source - that takes quite a long time!
A last reason (which is not important know because SUSE LINUX has a ugly workaround) is that yast is not able to handle packages for different architectures - it can only install packages for one architecture.
Debian How To Set Up A Load-Balanced MySQL Cluster
Post date: March 31, 2006, 14:03 Category: Software Views: 13
Tutorial quote: This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

In this document I use Debian Sarge for all nodes. Therefore the setup might differ a bit for other distributions. The MySQL version I use in this setup is 5.0.19. If you do not want to use MySQL 5, you can use MySQL 4.1 as well, although I haven't tested it.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.
