Installing Ruby on Rails Ubuntu 11.10 using RVM and Ruby 1.9.2
Posted by Tyler Allen in Fix It, Tutorial on November 21, 2011
Ruby Rails is a Web application framework created in 2004 intended as a rapid development web framework that runs the Ruby programing language. The latest version of the Ruby is ‘Ruby 1.9.2‘ and was realised in August 2011, it brings many new features and bug fixeses. The most signifiant changes are Block local variables, An additional lambda syntax, Per-string character encodings are supported and a new New socket API (IPv6 support). You can find a great walkthrough of all the new features at Ruby Inside. coinciding with the release of Ruby 1.9 is the Rails 3.1 framework which requires Ruby 1.8.7 or higher. RubyonRails 3.1 brings many new features, most notably: jQuery as default, HTTP Streaming, a new assets pipeline powered by Sprockets 2.0. So this is all good stuff and I’m sure you want to be working with the latest version of Ruby and RubyonRails, especially if you setting up a new server. Read the rest of this entry »
How To Install Ruby on Rails Ubuntu Server 11.10
Posted by Tyler Allen in Fix It, Tutorial on November 11, 2011
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 »
Enable potentially unsafe attachments in outlook
Posted by Tyler Allen in Fix It, Short on August 31, 2011
Ahh the “Outlook blocked access to the following potentially unsafe attachments” message, one of the most annoying things you can see when you in a hurry to get an attachment. However there is a good reason that attachments are disabled in outlook, some attachments can potentially be unsafe, as the warning says. But so long as you know were an attachment is from and you know the risks why can’t you enable these, after all you did pay for your computer and Office so you should be able to do what you want, right? Well in outlooks default setting there is no way to enable unsafe attachments, however there is a setting in the registry to enable them: Read the rest of this entry »
Developing Wesbites For iPhones
Posted by Tyler Allen in Code Snippets, Tutorial on August 10, 2011
So I’ve been developing a few websites mainly to be viewed on iPhones and iPods and this has raised several issues. Obviously you have to develop for mobile browsers such as safari which runs on iPhones or iPods and develop accordingly for this browser and the unique screen resolutions used on mobile devices. In this article I’m going to look at, what I feel, are the most important code snippets you’ll need to get started developing for iPhones or iPods. Read the rest of this entry »
Install and Configure a Ubuntu 11.04 Snort-MySQL Honeypot
Posted by Tyler Allen in Tutorial on August 9, 2011
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.

Simple C++ IRC Bot Template
Posted by Tyler Allen in Code Snippets, Tutorial on August 7, 2011
I searched the Internet, for quit a while, and I couldn’t find the source for a simple IRC bot in C plus plus, so I decided to write one using a TCP Stream Socket in C++. It works by setting up a simple TCP Socket to a IRC server on port 6667. The IRC Bot then assigns a NICK to the connection and connects to a IRC Channel. From here you can code you own commands and replies. I originally developed this to monitor IRC channels, however I came across a problem, PING. IRC servers periodically ping all clients to see if they are connected, so I added some more code to reply to these ping’s so that the bot stays connected. Read the rest of this entry »
C++ Simple Stream Socket Client Class

So I’ve been working on this project that heavily uses Sockets in C++, for the base of this project I’ve created a TCP Socket class so I concentrate on the protocol I’m using rather than worrying about the socket itself and I thought I would share this class with your. Read the rest of this entry »
Installing and Configuring Nagios Ubuntu 11.04
Posted by Tyler Allen in Fix It, News, Tutorial on July 18, 2011
Nagios is the Industry Standard Network Monitoring Engine. OK great so what’s that mean, well Nagios is a server that monitors your hosts and services and will inform you if something goes wrong and when it is fixed again. It can monitor network services, host resources and even network probes such as temperature and moisture.
These features as well as many more make Nagios, by far, the most complete open-source Network Monitoring tool on the market, however with all these features comes complexity and Nagios has obviously been designed with the experienced Network Administrator in mind. But don’t worry too much, its not that difficult to learn as long as you take it one step at a time, and in today’s tutorial we’re going to look at the first step, actually getting it installed Read the rest of this entry »
CPU Limit Ubuntu Server 11.04 Command Line
Posted by Tyler Allen in Short, Tutorial on July 11, 2011
I’ve was encrypting some files the other day with GPG and found that while the encryption was taking place my computer ground to a halt because GPG was taking up all of my CPU. Normally I wouldn’t mind this as I would just setup a few jobs and go make a cup of tea. Then I though what would happen if I run my encryption jobs on a webserver, well it grinds to a halt. So how do we run encryption jobs on our servers without affecting users, Read the rest of this entry »
