Installing Jinzora 3.0 Music Server

Jinzora 3.0 Login WindowJinzora is a web based media server and management system written in php. It enables you to play your music and organise your music from any computer connected to the internet. It can stream to different multimedia devices at multiple bandwidths, so you can listen to you music at home in high quality, listen to your home library from work, or even listen to your music using your Smart Phone on the train.

When i first setup a Jinzora server I was sceptical because every other media system Ive used hasn’t worked properly over the Internet. Jinzora on the other hand has no problem working over Internet, even when running on a slow Internet connection. So What do you need to setup a Jinzora server, first you’ll need a server running the LAMP stack, my simple tutorial for this setup can be found here. Read the rest of this entry »

Cloud Computing vs Dedicated Servers

Cloud ComputingAhh the eternal question, well it seems that way for the time being, there are hundreds of blogs and forums discussing this question and most of them seem one sided, but enough on that for now that start with the basics, What is Could Computing and Dedicated Servers, well:

Dedicated Server:
That’s start with the traditional way to outsource your servers, Dedicated Servers. This is when you buy a server in a data center somewhere and pay for it monthly, generally between $50 and $100 per month for a basic server. When you buy one of these there is generally a setup time as someone needs to go into the data center and install/setup your server.

Cloud Computing:
The new kid on the block, this is the new way of outsourcing your servers and runs on virtualisation software. There is large datacentre running virtualisation servers and these servers can produce large amounts of “Virtual Servers”. For the user these virtual servers look like a dedicated server, however they could be running on a variety of different servers. So it’s just like having a dedicated server but you don’t know what hardware it’s running on. Read the rest of this entry »

Installing Nagios on Ubuntu

nagios Logo

Nagios is the Industry Standard Network Monitoring Engine. OK great so whats 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 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 »

Large FLT Temp Files

Large FLT Temp files are created by the Windows Indexing Service. If you spent a lot of time connected to large network shares or have lots of small files on your computer then you may encounter problems. This is because the Indexing Service spends a lot of time creating indexes for all those files, this slows the computer down because the Indexing Service is constantly writing to the hard drive. The good news is that the Windows Indexing Service is not essential and if it’s slowing your computer down or its filling your hard drive up with large .FLT files you can disable it, this will fix the problem: Read the rest of this entry »

Setting up a LAMP Server

LAMP is a software bundle that’s consists of Linux, Apache2, MySQL and PHP. This is probably the most common web-server setup used today, this success can probably be put down to the fact all the software included in LAMP is open-source. Its also extremely easy to install and setup on an Linux computer.

For this tutorial I’m going to be using an amazon EC2 instance running Ubuntu, if you want to know how to run your own EC2 instance see my previous tutorial. However this tutorial should apply to almost any computer running a Ubuntu 7.4 or later. Read the rest of this entry »

New EC2 Cluster Compute Instances

When I heard the news that Amazon Web Services has just released there new “Cluster Compute Quadruple Extra Large” instance (cc1.4xlarge), I couldn’t help but give it ago. On paper this instance should have more CPU power then any other instance, at around 33.5GHz witch is substantially more then the c1.xlarge that has only 20Ghz of CPU power. This coupled with a 10 Gigabit Ethernet connection makes this instance ideal for High Performance Clustered Applications.

So does it live up to expectations, well I’m going to run some LINPACK benchmarks on this new instance to see how fast it relay is, and compare it to the other amazon instances. So… Read the rest of this entry »

Running an Amazon EC2 Linux Instance

Ubuntu LogoWell if you read my previous tutorial then hopefully you’ll have an understanding of how to setup and run an Amazon EC2 Windows Instance, In this tutorial I’ll go through how to setup a Linux instance, don’t worry I’ll go through it from the start so you don’t need to read my Windows Tutorial if you don’t want.

I used Windows for my first tutorial because nearly everyone has used it at some point. However Windows has many drawbacks, the first and foremost being its Windows and it also takes 15 minutes to start-up. Linux only takes a few minutes to power up, however it does not have a nice GUI like windows, you’ll have to use the fun fun Command line, no seriously its more fun then windows, it doesn’t crash.

So how do you get one of these fast and reliable Linux instances up and running, well…. Read the rest of this entry »
