Jabber Openfire Server

by 2 others
Openfire (formerly Wildfire) is a real time collaboration (RTC) server dual-licensed under the Open Source GPL and commercially. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber). Openfire is incredibly easy to setup and administer, but offers rock-solid security and performance.

How to customize xplanet-gnome

Ok, now you have xplanet-gnome set up. Here's how you can customize it by editing the script. We'll go through the script line by line and examine what all of the parts do. So, let's get to it.

If you’ve ever thought that having one particular image on your desktop gets a bit dull, then this may be something for you. xplanet generates images of the Earth at set intervals (for example every 10 minutes) that shows the Earth roughly at this point in time. In addition, what I have here is cloud cover updated every 3 hours, so it’s like a weather map.

by 3 others (via)
Ce guide est destiné à toute personne qui, venant d'acquérir (ou prévoyant d'acquérir) un ordinateur avec des logiciels pré-installés dont il n'aura pas l'usage, souhaite obtenir leur remboursement à des conditions acceptables.

Remarque importante : ce guide est conçu pour aider à obtenir le remboursement du système d'exploitation (Windows, MacOS,...), et avec lui de l'ensemble des logiciels pré-installés. Mais les principes qu'il expose sont valables pour toute demande portant sur une partie seulement de ces logiciels (ex : Works OEM) payants ou supposés tels.

Using Nagios to Monitor Networks

Nagios is a powerful, modular network monitoring system that can be used to monitor many network services like smtp, http and dns on remote hosts. It also has support for snmp to allow you to check things like processor loads on routers and servers. I couldn't begin to cover all of the things that nagios can do in this article, so I'll just cover the basics to get you up and running.

EeePC

The Asus EeePC is a low cost ultra portable notebook computer. To install Ubuntu on the Asus EeePC in it's stock form, you will have to create a USB based bootable installer or use a USB-connected CD-ROM drive to run/install Ubuntu. In addition to this, a few simple software modifications will have to be completed for hardware support.

eeeXubuntu [EeeUser Eee PC Wiki]

by 1 other
eeeXubuntu is a custom version of the Xubuntu 7.10 Live CD with fully-integrated hardware support, including native wireless drivers, functioning Ethernet support, tweaks for low-resolution desktop environments, and other miscellaneous fixes. Wherever possible, these changes are incorporated using custom .deb packages rather than spewing assorted files all over post-install. (Screenshot) The goal of this project is to maintain a easy-to-install Xubuntu Live CD image for the eeePC, allowing for a reliable base Xubuntu install. One strong advantage of development for the eeePC is a common hardware platform shared by all users. (Those who are missing a miniPCI slot may, of course, disagree.)

How to get your MySQL Munin Graphs working

I run a few cPanel servers and run Munin as my resource monitor. At the time I wrote this the version included with cPanel was munin 1.24. Ever since I have installed the plugin from cPanel it would monitor MySQL upon first install and then stop if the server was reboot. Uninstalling and reinstalling would once again get Munin to monitor MySQL but having to uninstall and reinstall just for a reboot, just did not seem like something that you should have to do. After many months of on and off testing this is the fix I have come up with.

Monitoring Servers and Clients using Munin in Ubuntu

“Munin” means “memory”.Munin the tool surveys all your computers and remembers what it saw. It presents all the information in in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, and quite possibly applications as well. It makes it easy to determine “what’s different today” when a performance problem crops up. It makes it easy to see how you’re doing capacity wise on all limited resources. It uses the excellent RRDTool and is written in Perl. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for sdata. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).

How-To: Monitoring a Server with Munin

Munin is a simple to configure tool that make real nice graph about your server status. It can actually deal with almost any aspect of your server (load average, network cards status, CPU usage, memory usage, postfix, exim4, mysql ...) without spending much time in configuring it. Munin produce MRTG likes graph so you can easily see how your server health is going.

Munin, une alternative simple à Cacti?

by 1 other
Cela fait près d’un an et demi que j’utilise le logiciel Cacti pour monitorer l’activité réseau. Aussi bien dans le cadre de mon activité professionnelle que pour mon usage personnel. Mais j’ai récement découvert une alternative sérieuse : Munin. Celui-ci présente de nombreux avantages par rapport à Cacti et mérite d’être plus connue.

Postfix Cyrus IMAP SSL LDAP

La série d'articles de cette rubrique est entièrement dédiée à la mise en oeuvre d'un serveur de mail basé sur Postfix et Cyrus-Imap. Ces deux éléments sont tout simplement ce qui ce fait de mieux actuellement dans leur domaine respectif: * Postfix : protocole smpt ou smtps pour le mode sécurisé * Cyrus imap : protocole POP3 ou POP3S (mode sécurisé) ou IMAP ou IMAPS (mode sécurisé).

WebDav Autoversioning

A while back I stumbled upon a lesser known feature of SVN and WebDav, but didn’t have the time to blog about it until now. WebDAV and SVN is an exceedingly useful tool as we all know, and pretty damn easy to setup, see here. But what if you could have everything entered into the WebDav repository automatically versioned into a repository. Well you can! And the good news is, it’s really really easy.
