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

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.

Détails du matériel - mumbly's world

Toute petite astuce sous forme de note. Pour connaitre plus précisément le matériel de votre ordinateur, et pour voir comment il est reconnu sous votre Ubuntu préféré : $lspci -n Puis, copiez la sortie complète de la commande précédente à cette adresse : http://kmuto.jp/debian/hcl/ Cliquez sur CHECK. Très intéressant, notamment au niveau des drivers.

utiliser apt-cacher pour les mises à jour de vos machines Debian - ka.da

Que ce soit à la maison ou au travail, quand on commence à avoir beaucoup de machines Debian, se pose le problème de leurs mises à jour et surtout de la bande passante utilisée pour celles-ci. Au niveau Debian, plusieurs solutions existent, comme utiliser un proxy web classique (Squid par exemple), partager le répertoire contenant les fichiers téléchargés (ce qui peut être un peu risqué), répliquer complètement l'arborescence Debian (mais ça demande à télécharger des paquets dont probablement on ne se servira jamais) ou bien encore utiliser un outil dédié à ce problème. Plusieurs existent : apt-proxy, approx, apt-cacher. Il semble que de ces différentes solutions aucune ne ressorte vraiment, et que des problèmes existent sur chacune d'elle. En tout cas, ici, je vais vous présenter apt-cacher.

Nous verrons dans cet article comment installer Xen sur une machine n'ayant pas les instructions matérielles de virtualisation (VT) en utilisant LVM pour partitionner avec flexibilité nos différentes machines virtuelles. Le tout est réalisé grâce à Debian Etch avec les bons noyaux qui vont bien. J'ai aussi utilisé le noyau officiel de chez Xen afin d'avoir quelque chose de propre (enfin dans la limite du possible). Attention, mon tutoriel prends de véritables adresses IP, je n'ai donc aucun besoin de NAT. Si tel est votre problème, achetez le numéro 100 de GLMF, il contient le serveur parfait et un setup bien plus avancé que le miens :)

HA Xen Cluster with DRBD, LVM and heartbeat

We have implemented a 2-node HA Xen cluster, which consists of two physical machines (hosts,) and runs several virtual servers (guests) each, for our company's internal services (mail, web applications, development, etc.) When one host gets down unexpectedly, the other host physically kills it (STONITH - power down or reset) and then takes over all the guests the failed host was running. When we want to shutdown a host machine for maintenance (to replace a fan, add disk or memory, etc.), we just type the usual shutdown command, and the guests are automatically live-migrated to the other host. Since the guest servers keep running throughout the migration process, except for the less than a second pause, users would never even notice the event.

Xen Cluster Management With Ganeti On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 1 other
Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.

This tutorial explains how to convert a VMWARE image of a Debian Etch to a XEN image on a Debian Sid dom0 using XEN 3.0.3.

How To Make Your Xen-PAE Kernel Work With More Than 4GB RAM (Debian Etch With GRUB) | HowtoForge - Linux Howtos and Tutorials

If you have a server with more than 4GB RAM and want to install a 32bit Debian Etch on it (following this tutorial: Debian Etch And Xen From The Debian Repository), you'd expect the Xen-PAE kernel to see all your RAM because the Xen-PAE kernel supports up to 64GB RAM. In fact, it recognizes only about 3.3GB RAM due to a bug in the GRUB bootloader. This article explains how you can fix GRUB so that all your RAM gets recognized. I do not issue any guarantee that this will work for you!

ssh on multiple servers Using cluster ssh -- Debian Admin

Ever had to make the same change on more than one Linux/unix server? Find it annoyingly painful to keep repeating the exact same commands again and again and again? This tool addresses exactly this problem. You run a utility (cssh) providing a number of server names as parameters, and then xterms opens up to each server with an extra “console” window. Anything typed into the console is replicated into each server window (so, for examples, you can edit the same file on N machines at the same time, or run the same commands with the same parameters across those servers). It is also possible to type into the server windows directly, or temporarily disable replication to one or more of the servers through the “Hosts” menu.

Sauvegarder la liste des paquets debian • Balluche

Sous Ubuntu (ou autre debian) il existe différentes façons de mettre à jour l'OS lors de la sortie d'une version majeure. Personnellement j'ai pris l'habitude de reformer la partition système. Dans ce cas, il est essentiel de conserver la trace des paquets installés

Setting Up A High-Availability Load Balancer (With Failover and Session Support) With Pound/Keepalived On Debian Etch | HowtoForge - Linux Howtos and Tutorials

This article explains how to set up a two-node load balancer in an active/passive configuration with Pound and keepalived on Debian Etch. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using keepalived, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. Pound is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.).
