Preventing MySQL Injection Attacks With GreenSQL On Debian Etch

Post date: October 28, 2008, 12:10 Category: Security Views: 3731 Comments
Tutorial quote: GreenSQL (or greensql-fw) is a firewall for MySQL databases that filters SQL injection attacks. It works as a reverse proxy, i.e., it takes the SQL queries, checks them, passes them on to the MySQL database and delivers back the result from the MySQL database. It comes with a web interface (called greensql-console) so that you can manage GreenSQL through a web browser. This guide shows how you can install GreenSQL and its web interface on a Debian Etch server.

Preventing Brute Force Attacks With BlockHosts On Debian Etch

Post date: September 30, 2007, 09:09 Category: Security Views: 4053 Comments
Tutorial quote: In this article I will show how to install and configure BlockHosts on a Debian Etch system. BlockHosts is a Python tool that observes login attempts to various services, e.g. SSH, FTP, etc., and if it finds failed login attempts again and again from the same IP address or host, it stops further login attempts from that IP address/host. By default, BlockHosts supports services that use TCP_WRAPPERS, such as SSH, i.e. services, that use /etc/hosts.allow or /etc/hosts.deny, but it can also block other services using iproute or iptables.

Installing memcached And The PHP5 memcache Module On Debian Etch (Apache2)

Post date: September 11, 2008, 11:09 Category: Optimizing Views: 6310 Comments
Tutorial quote: This guide explains how to install memcached and the PHP5 memcache module on a Debian Etch system with Apache2. memcached is a daemon that can store objects in the system's memory (e.g. results of database queries) which can speed up your web site tremendously. You can use memcached over a network (i.e., install your web application on one server and memcached on another server), but usually you install both on one server to avoid the networking overhead.

Creating Advanced MySQL-Based Virtual Hosts On Lighttpd (Debian Etch)

Post date: August 19, 2008, 10:08 Category: Software Views: 3161 Comments
Tutorial quote: This guide explains how you can create advanced virtual hosts on a lighttpd web server on Debian Etch that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a database), this method allows to store individual configuration directives for each vhost in the MySQL database.

Creating A Fully Encrypted Para-Virtualised Xen Guest System Using Debian Lenny

Post date: May 3, 2009, 10:05 Category: Miscellaneous Views: 3404 Comments
Tutorial quote: This document explains how to set up a fully encrypted para-virtualized XEN instance. In this howto, the host system is running Debian Etch, while the guest system to be installed will be using Debian Lenny. If you are concerned about your privacy, you might want to consider using hard disk encryption to protect your valuable private data from spying eyes. Usually, the easiest way would be to use your distribution's installer to set up a fully encrypted system; I think most recent Linux distributions support this. However, when you are using XEN to provide virtualization, there are situations where you might not want to encrypt your whole computer with all guest instances, but instead only encrypt one OS instance. This howto will deal with exactly this situation. It assumes that the XEN host system is already up and running.

Setting up a local web server in Debian Linux

Post date: January 21, 2006, 06:01 Category: Network Views: 2704 Comments
Tutorial quote: Any web developer, designer, or webmaster can benefit from having a local web server. Even if that developer has no interest in securing and maintaining the server his or her websites live on, a local server can act as a convenient mirror for testing updates, trying new designs, and other general sand-boxing activities.

Web developers whose hosts utilize the popular LAMP platform (Linux + Apache + MySQL + PHP) are frequently hit with a dilemma. Since understanding Linux is not a prerequisite for website administrators, many of them lack the knowledge necessary for setting up a LAMP server from scratch (or at least they may think so). But thanks to the improved package management on Linux distributions like Debian, installing a functional web server is not nearly the chore it was just a couple years ago.
