Ubuntu Administrator

by 2 others (via)
This site will hope to provide both content and community for those who are interested in Ubuntu on the server. Ubuntu, more often than not, is viewed as a newby distribution for desktop use. Even though Ubuntu makes a great desktop, it also makes a great robust server as well and this site hopes to focus on that. The framework of the site is still being developed so bare with me here a bit, but enjoy!

How To Back Up An Ubuntu 8.10 System With SystemImager | HowtoForge - Linux Howtos and Tutorials

by 1 other (via)
SystemImager lets you create images of your Linux installations. To do so, you need an image server (should have enough disk space to store your images) and a so-called golden client (i.e., the system of which you want to make an image). This means that you have to install some software on your image server and on your golden client in order to run SystemImager. This tutorial shows how to install a SystemImager server and a SystemImager client, both using Ubuntu 8.10, and how to create/update/restore/delete images.

Tentakel to execute commands on multiple Linux or UNIX Servers

Many times, you want to execute a command not only on one server, but also on several servers. For example, find out * Version of kernel * Version of Apache web server * Update static html or images files on all web servers via rsync * Find out user information, server information, memory usage etc * Security/patch checking tentakel I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group.

VBoxHeadless - Running Virtual Machines With VirtualBox 2.0 On A Headless Ubuntu 8.04 Server | HowtoForge - Linux Howtos and Tutorials

This guide explains how you can run virtual machines with Sun xVM VirtualBox 2.0 on a headless Ubuntu 8.04 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 1 other (via)
This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.

XBMC Media Center // Home //

XBMC [1] signifiait anciennement XBox Media Center mais depuis la sortie de ‘Atlantis’ [2], nom de code donné à sa dernière mouture actuellement en Beta, cela n'est plus vrai. En effet, XBMC devient multi-plateforme et son acronyme devient récursif (XBMC Media Center). XBMC est pour ceux qui ne l'aurait pas encore remarqué un centre multimédia initialement conçu pour ne fonctionner que sur la console de jeux de Microsoft : la Xbox de première génération. Cependant, les utilisateurs souhaitaient pouvoir utiliser leur fabuleux centre multimédia sur d'autres plateformes et donc un gros travail de portage a été lancé. Ce travail abouti maintenant avec une première version Beta disponible d'hors et déjà sur les différentes plateformes concernées [3]. Vous trouverez donc une version "live" à mettre sur CD-ROM ou clé USB, une version Window XP/Vista, une version MacOS X et bien sûre une version pour GNU/Linux. XBMC est toujours disponible pour sa plateforme de prédilection et ne compte pas l'abandonner mais pour des raisons de légalité, il est impossible de fournir le binaire créé à l'aide du kit de développement de la Xbox délivré par Microsoft. Il faut alors acquérir ce kit (de manière plus ou moins légale) et compiler soit même le binaire pour la version Xbox. Au niveau des fonctionnalités, on peut déjà dire que XBMC se base sur de nombreux projets libres pour accomplir ses tâches. Par exemple, MPlayer pour la lecture de nombreux formats audios et vidéos, FFmpeg pour la lecture des DVD, Filezilla pour l'accès FTP, Samba pour le partage de fichiers, etc... Un listing complet des fonctionnalités est disponible en [4]. Vous n'avez donc plus aucune raison pour tester et profiter de ce fabuleux logiciels ;) [1] http://xbmc.org/ [2] http://xbmc.org/blog/2008/09/18/xbmc-atlantis-beta-1-release(...)

How To Set Up A Loadbalanced High-Availability Apache Cluster Based On Ubuntu 8.04 LTS | HowtoForge - Linux Howtos and Tutorials

This tutorial shows how to set up a two-node Apache web server cluster that provides high-availability. In front of the Apache cluster we create a load balancer that splits up incoming requests between the two Apache nodes. Because we do not want the load balancer to become another "Single Point Of Failure", we must provide high-availability for the load balancer, too. Therefore our load balancer will in fact consist out of two load balancer nodes that monitor each other using heartbeat, and if one load balancer fails, the other takes over silently.

How To Set Up A Debian Linux WebCam Server Using a USB Web Cam

by 1 other
First and foremost, be prepared to have some patience when trying to get a USB cam to work under Linux. In trying to get mine to work, I searched many a newsgroup thread only to find there was only one message in the thread, the original question stating the problem. i.e. no one had an answer for the person who posted the question so you may be on your own trying to get your cam to work. Often times the same camera model will use different drivers for different sub-models (ex: not all QuickCam Express sub-models use the same driver). However, my trials and tribulations were a good learning experience and I'll share what I learned here to hopefully make your setup easier.

How To Install And Use The djbdns Name Server On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 1 other
djbdns is a very secure suite of DNS tools that consists out of multiple parts: dnscache, a DNS cache that can be used in /etc/resolv.conf instead of your ISP's name servers and that tries to sort out wrong (malicious) DNS answers; axfrdns, a service that runs on the master DNS server and to which the slaves connect for zone transfers; and tinydns, the actual DNS server, a very secure replacement for BIND.

This tutorial shows how to install Lighttpd behind Apache via Apache´s proxy module.

How to install the WiKID Strong Authentication Server - Community Edition | HowtoForge - Linux Howtos and Tutorials

The WiKID Strong Authentication Server is a dual-source two-factor authentication system. PINs are encrypted on a software token and sent to the WiKID server. If the PIN is correct, the encryption valid and the account active, a one-time password is generated, encrypted and returned to the user's token where it is decrypted and presented for use with a network-based services. While there are a number of tutorials on how to combine WiKID's two-factor system a variety of systems (such as SSH, OpenVPN, Apache and SSL-VPNs), this is the first to address how to install the WiKID Server. We assume that you have already configured an RPM-based server. In general, it is best to have WiKID be the only service running on the server. This configuration will minimize potential security risks.
