This tutorial shows how to combine four single storage servers (running Ubuntu 11.10) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work.

Using mod_spdy With Apache2 On Debian Squeeze

SPDY (pronounced "SPeeDY") is a new networking protocol whose goal is to speed up the web. It is Google's alternative to the HTTP protocol and a candidate for HTTP/2.0. SPDY augments HTTP with several speed-related features such as stream multiplexing and header compression. To use SPDY, you need a web server and a browser (like Google Chrome and upcoming versions of Firefox) that both support SPDY. mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This tutorial explains how to use mod_spdy with Apache2 on Debian Squeeze.

Remotely Unlock Fully Encrypted Debian Squeeze

In the past I have written several howtos for remotely unlocking fully encrypted Debian installations. With the advent of Debian Squeeze, the developers have integrated a simple way to do so. Most stuff is provided directly by Debian itself - meaning you don't need 3rd party scripts anymore. However it still involves a few steps which I describe below. Also I provide you with a bash script that will do all the steps automatically.

This guide explains how you can configure DNSSEC on BIND9 on Debian Squeeze and Ubuntu 11.10. It covers how to enable DNSSEC on authoritative nameservers (master and slave) and on resolving nameservers, creation of keys (KSKs and ZSKs), signing of zones, key rolling with rollerd, zone file checking with donuts, creation of trust anchors, using DLV (DNSSEC look-aside validation), and getting your DS records into the parent's zone.
