«One year after the release of Debian GNU/Linux 5.0 alias "lenny" and nearly three years after the release of Debian GNU/Linux 4.0 alias "etch" the security support for the old distribution (4.0 alias "etch") is coming to an end next month. The Debian project is proud to be able to support its old distribution for such a long time and even for one year after a new version has been released...»

This tutorial was written for the Debian Lenny distribution and supposes that the user has knowledge about what load balancing is and some basic skills of Linux, our two load balancers consist out of 2 machines that monitor each other [heartbeat], if the master stops responding the secondary one [Backup] will take the master role [Backup -> Master].

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

mod_qos gives some fine-grained opportunities to scale the number of used connections and to defend an attack according to bandwidth limits. Unfortunately it is only available as source-package and there are many possible settings, wich might be hard to set up for this special case. So I provide the way that helped me.

This tutorial shows how to set up a PXE (short for preboot execution environment) install server on Debian Lenny. A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc.

This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and keepalived on Debian Lenny. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content.

"Hi, As you probably know, back in December last year it was decided that the Linux package shipped with Debian Lenny would include non-free code in it (so-called "blobs" of binary-only firmware).
