Debian Change your Network card MAC ( Media Access Control) address
Post date: December 4, 2007, 10:12 Category: Network Views: 1335 Comments: 0
Tutorial quote: Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

If you want to change your network card mac address you need to use simple utility called mac changer.MAC changer is a utility for manipulating the MAC address of network interfaces
Debian How To Set Up Software RAID1 On A Running System (Incl. GRUB Configuration) (Debian Etch)
Post date: November 29, 2007, 11:11 Category: Installing Views: 1304 Comments: 0
Tutorial quote: This guide explains how to set up software RAID1 on an already running Debian Etch system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).
Debian How To Enable Multiple HTTPS Sites For One IP On Debian Etch Using TLS Extensions
Post date: November 19, 2007, 11:11 Category: Software Views: 1360 Comments: 0
Tutorial quote: This guide is Debian specific but could be ported to other distributions since the concept is the same. In order to use TLS Extensions we have to patch and recompile Apache2 and recompile OpenSSL with the enable-tlsext directive. Since TLS extensions are relatively new, some Internet browsers will not work so the Apache2 server will deliver just the default site as http 1.0 does on an http 1.1 server.
Debian Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Debian Etch
Post date: November 7, 2007, 11:11 Category: Network Views: 1768 Comments: 0
Tutorial quote: This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat 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 heartbeat, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.).
Debian Full Mail Server Solution With Virtual Domains & Users (Debian Etch, Postfix, MySQL, DoveCot, DSpam, ClamAV, Postgrey, RBL)
Post date: October 31, 2007, 09:10 Category: Installing Views: 1913 Comments: 1
Tutorial quote: This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch). I was asked to design a secure, scalable, portable solution for a small company. While the guide references many servers, the company only had 4 physical machines, Xen was used to virtualize the entire solution. That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision.

Debian Setting Up Master-Master Replication With MySQL 5 On Debian Etch
Post date: October 25, 2007, 11:10 Category: Miscellaneous Views: 1479 Comments: 0
Tutorial quote: Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you do not have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.
Debian How To Install A Complete LEMP (Linux - EngineX (Nginx HTTP SERVER) - Mysql - PHP) Server On Ubuntu/Debian
Post date: October 19, 2007, 09:10 Category: Installing Views: 1502 Comments: 0
Tutorial quote: This HowTo will describe the setup of an efficient http server and mail server for small or medium configurations (as low as 96 mb). Why LEMP instead of LAMP? NGINX is a great replacement for Apache with very low memory footprint and great stability.
Debian Using ATA Over Ethernet On Debian Etch
Post date: October 17, 2007, 11:10 Category: Hardware Views: 2218 Comments: 0
Tutorial quote: Imagine you have a machine with all of its disk full and another with unused gigabytes, and you do not want to move the data from one to the other. Why not use the second's disk on the first, you could do it with iSCSI, but you can do it with ATA over Ethernet (AoE) as well. It is the second method I will explain in this article. All of this was made with two computers running Debian Etch.
