This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on Ubuntu 11.10. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

Proxmox Virtual Environment is an easy to use Open Source virtualization platform for running Virtual Appliances and Virtual Machines. Proxmox does not officially support software raid but I have found software raid to be very stable and in some cases have had better luck with it than hardware raid.

This tutorial shows how you can set up an Ubuntu 12.04 (Precise Pangolin) desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

This tutorial shows how to prepare an Ubuntu 12.04 LTS (Precise Pangolin) server (with Apache2, BIND, Dovecot) for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).

This tutorial explains how you can integrate ClamAV into PureFTPd for virus scanning on a Debian Squeeze system. In the end, whenever a file gets uploaded through PureFTPd, ClamAV will check the file and delete it if it is malware.

This document describes how to deploy AVG Antivirus for Linux/FreeBSD to the Qmail mail server. It is usable for AVG version 8.5, 10 and 2012. By using AVG Antivirus with your Qmail mail server, you can ensure virus-free inboxes.

We're going to set up a free, full-featured mail server on CentOS 6.2, all mail service related components are free and open source, and you have control over your own data. The installation process is extremly easy and smooth.

The new Ubuntu 12.04 LTS (Precise Pangolin) has just been released. Ubuntu 12.04 LTS is a long-term support release, which means it is supported for five years. This guide shows how you can upgrade your Ubuntu 11.10 desktop and server installations to Ubuntu 12.04 LTS.

This tutorial shows how to do data striping across four single storage servers (running Ubuntu 11.10) with GlusterFS. The client system (Ubuntu 11.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

SPDY (Speedy) is an experiment with protocols for the web. Its goal is to reduce the latency of web pages. mod_spdy is an open-source Apache module which supports the use of SPDY protocol to the Apache HTTPD server. This allows for faster page loading and more efficient bandwidth utilization when loading https URLs in SPDY-enabled browsers.

sitecopy is a tool for copying locally stored web sites to a remote web server (using FTP or WebDAV). It helps you to keep the remote site synchronized with your local copy by uploading modified local files and deleting remote files that have been deleted on the local computer. This tutorial shows how you can manage your remote web site from your local Debian Squeeze/Ubuntu 11.10 desktop with sitecopy.

This guide explains how to set up WebDAV with MySQL authentication (using mod_auth_mysql) on Apache2 on a Debian Squeeze server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via http://FTP. Of course, WebDAV can also be used to upload and download files.

This guide explains how to install the phpMyAdmin alternative Chive. Chive is a free, open source, web-based database management tool with easy administration, super fast UI and state of the art web technologies. It takes advantage of the capabilities of modern browsers. Features include an SQL editor with syntax highlighting and built-in profiling of SQL queries.

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.

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.

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.

This tutorial explains how you can simulate network devices for testing purposes with the free Verax SNMP Simulator. Verax SNMP agent simulator is a tool that can simulate multiple SNMPv1/v2c agents on a single host on standard 161 port through multi-netting. It allows IT personnel to build virtual, simulated networks of devices without purchasing any additional hardware, for instance for testing purposes. Individual simulated agent responses can be initially retrieved from existing devices and modified at runtime by user defined rules.

This guide explains how you can set up an iSCSI target and an iSCSI initiator (client), both running Debian Squeeze. The iSCSI protocol is a storage area network (SAN) protocol which allows iSCSI initiators to use storage devices on the (remote) iSCSI target using normal ethernet cabling. To the iSCSI initiator, the remote storage looks like a normal, locally-attached hard drive.

This HOWTO describes how to protect your home / small enterprise network users from objectionable internet contents with help of HTTP proxy. Our goal is to set up a free Linux based server running Squid and deploy web filtering application on it saving bandwidth, speeding up web access and blocking obsessive and potentially illegal and malicious web files.
