How To Install Ruby on Rails Ubuntu Server 11.10

Ruby Rails is a Web application framework created in 2004 intended as a rapid development web framework. It was intended to emphasize Convention over Configuration (CoC) meaning the developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table “products sold”, that the developer needs to write code regarding these names. It has also been designed around the “Don’t repeat yourself” principle. Both of these ways of thinking allow you, with Ruby Rails, to create excellent, dynamic websites very quickly. So to get started we need to setup a Ruby Rails development server on Ubuntu (Ubuntu 11.04, Ubuntu 11.10) Read the rest of this entry »

Install and Configure a Ubuntu 11.04 Snort-MySQL Honeypot

An Intrusion Detection system is like a burglar alarm for your computer. It monitors you network and system activities for malicious activities or policy violations and reports to some kind of management station. This is great as it lets you know who were when & how people are trying to break into your network and knowing this is half the battle. You may be thinking that this isn’t enough and you want to block all hacks from happening, well most IDS systems include some “Network Intrusion Prevention” features. However the main concern should be closing up vulnerabilities rather than blocking someone already trying to hack your systems, after all it’s a bit late if they are already in your system, and this way you may accedently block innocent users.

Setting Up an Basic IRC Server on Ubuntu

IRC Funny Cartoon Ahh the good old IRC server, these things have been letting people chat to each other since 1988. In there most basic form they are chat room servers, pretty much every chat room you’ve used on a web page is connecting to an IRC server. They definitely have a place in computing history as they were used to report on the 1991 Soviet coup d’état attempt and Gulf War during media blackouts.  But they have become much more then simple chat rooms, they allow for: File Transfer, Encryption, Proxy, Colour, Channels, Users, and even chat bots.

Sadly the IRC chat room  are being replaced by things like MSN and Facebook messenger. They are great to install on web servers because they allow you to include chat rooms into your websites, or just to play with something that’s been such an important part of computing history.
