Post date: May 27, 2007, 23:05 Category: System Views: 3670 Comments
Tutorial quote: This article shows how you can install Ruby on Rails (RoR) and integrate it in Apache2 on a Debian Etch system. Ruby on Rails is a web application framework which is rapidly gaining popularity among web programmers. It aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset. Applications using the RoR framework are developed using the Model-View-Controller design pattern.

Installing PowerDNS (With MySQL Backend) And Poweradmin On Debian Etch

Post date: January 20, 2009, 11:01 Category: Installing Views: 3375 Comments
Tutorial quote: This article shows how you can install the PowerDNS nameserver (with MySQL backend) and the Poweradmin control panel for PowerDNS on a Debian Etch system. PowerDNS is a high-performance, authoritative-only nameserver - in the setup described here it will read the DNS records from a MySQL database (similar to MyDNS), although other backends such as PostgreSQL are supported as well. Poweradmin is a web-based control panel for PowerDNS.

Have a Bash With This Linux Shell

Post date: April 15, 2005, 05:04 Category: Programming Views: 3087 Comments
Tutorial quote: Any Linux administrator who wishes to remain sane relies heavily on scripting to automate routine tasks, customize jobs, and build the plumbing that connects the different utilities that make a Linux system run smoothly. The Linux world is chock-full of scripting languages: Perl, Python, PHP, Scheme, Tcl, Tk, Ruby, Forth, Smalltalk, Eiffel, and doubtless many more. To get the column started, we'll look at shell scripting with Bash, and scripting with Python and Perl.

Installing Joomla 1.5.6 On A Lighttpd Web Server (Debian Etch)

Post date: September 16, 2008, 10:09 Category: Installing Views: 3251 Comments
Tutorial quote: This guide explains how you can install Joomla 1.5.6 on a lighttpd web server on Debian Etch. Joomla comes with an .htaccess file with mod_rewrite rules (for Apache) (to enable search-engine friendly URLs) that do not work on lighttpd. Fortunately Joomla has a built-in method to make search-engine friendly URLs work on lighttpd as well.

Preventing MySQL Injection Attacks With GreenSQL On Debian Etch

Post date: October 28, 2008, 12:10 Category: Security Views: 3690 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.

Creating a Wiki with kwiki

Post date: December 17, 2005, 22:12 Category: Software Views: 2681 Comments
Tutorial quote: Wikis are simple interactive websites which are extremely easy to use for storing easily updated text content. Using a Wiki you can easily create a lot of content with hyperlinks between them. Debian has packaged several different Wiki systems and here we'll look at installing just one of them: KWiki.

Wikis have become familiar to many people thanks to the popularity of large sites such as Wikipedia and can be very useful for creating collaborative websites.

Whilst there are many Wiki packages included in the Debian GNU/Linux distribution I've always had a soft spot for KWiki due to its simplicity, Perl nature, and low requirements.

Installing the software under Debian is very simple and we will show how to setup a new installation using the Debian Apache2 webserver package.

Preventing Brute Force Attacks With BlockHosts On Debian Etch

Post date: September 30, 2007, 09:09 Category: Security Views: 4013 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: 6253 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: 3121 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.

How To Patch BIND9 Against DNS Cache Poisoning (Debian/Fedora/CentOS)

Post date: July 29, 2008, 09:07 Category: Security Views: 3571 Comments
Tutorial quote: Dan Kaminsky earlier this month announced a massive, multi-vendor issue with DNS that could allow attackers to compromise any name server - clients, too. These two articles explain how you can fix a BIND9 nameserver on Debian Etch and Fedora/CentOS so that it is not vulnerable anymore to DNS cache poisoning.
