Nagios is the Industry Standard Network Monitoring Engine, however it can be a pain to set up and configure. We’ll it doesn’t always need to be that way there are a few other systems you could use that are much easier to setup and configure so much so you might even be able to get your end-users to manage their own monitoring configuration. So here is my Top 5 easy Nagios setup solutions Read the rest of this entry »
Can I connect to an amazon instance and create more instances? I have heard this question several times now and the answer is yes. You are limited to running 20 On-Demand and 100 Spot Instances per region with Amazon EC2. If that not enough for you then you’ll need to file a Request to Increase the EC2 Instance Limit, to use more instances.
Each instance is basically a virtual machine running on amazons infrastructure, and each instance is allocated its own address allowing you to connect to it. Because each instance runs independently you can connect to as many as you want simultaneously. Read the rest of this entry »
So you want a Dedicated or Cloud server, or you already have one and you want to know what to do with it, well there are many uses for remote servers, just check out the long list at ubuntu.com. But witch ones are actually worth installing, well that depends on your needs, if you need a web-server then install LAMP, if you need a chat server install IRC. But its always good to look at other servers you can install because it might inspire you to improve your service, If you are already running a popular website on a LAMP server you might not realise you could install an IRC server and provide your readers with a chat room. So read on for my Top 10 uses for a sever Read the rest of this entry »
On a more light-hearted subject, what are my Top 10 Favourite Command line games for Linux? I bet you’re asking yourself why command line games?

Ahh 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:
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.
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 »
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 »
