Can I connect to an amazon instance and create more instances?

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 »

Have you ever had your computer lost or stolen, had to format it, or had a corrupted HDD, well if you have you’ll know its a pain, especially when trying to get you data back. Now with high-speed networks and cheap storage its becoming more common to backup are data remotely. This helps reduce data lost in the event your computer is lost or damaged.

This is all fair and well for your documents, you just copy them to a remote server and you can sleep safe in the knowledge your files will be OK. But what about your emails, these can be just as important, if not more, then your documents, in fact someone told me the other day that his emails were like is calendar and identity and would be completely lost without them, so its worth ensuring they are all backed up correctly.

Snort Email Reports

Snort has many logging ability’s, syslog, unixsock, tcpdumps, csv, xml, unified and my favourite, database. All these logging methods are great if you are going to look through your logs regularly. But if your busy doing other things or maintaining snort isn’t you main priority how are you expected to keep up to date with the logs.

I find that having snort email me every morning with a simple report is a much better way of ensuring that no one is attacking my systems. It only takes me a minute to read through the report and if there is something I think needs looking at I can easily log into my database and get as much information on the event as I need. So how do you setup email reports, well if you installed Snort on a Debian based system it is already installed, just not setup correctly: Read the rest of this entry »

Add NRPE host to Nagios

nagios Logo NRPE (Nagios Remote Plugin Executor) is a Nagios agent witch allows for remote system monitoring by executing scripts on a remote system allowing monitoring of disk usage, system’s load or number of users currently logged in and much more.

Normally Nagios can only monitor public services such as HTTP & FTP. This is great if you only want to monitor public servers, however I bet that most people want to monitor their own servers and have access to private information, that’s were NRPE comes in. It works on a client server basis, you install a daemon on the machine you want to monitor, then setup your Nagios server to connect to the remote daemon to gather information Read the rest of this entry »

IP Address Basics

Network Lead with some IP address stuffIf you want communicate with someone then you’ll need some kind of address, weather this be an house address, telephone number or even email, otherwise how will your message reach its destination.

This is called an IP Address (Internet Protocol Address) and nearly every computer with a network card will have one. So how do IP Address work and how do they affect me?

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.

Donate you Spare CPU Time to Science

I’m talking about Folding@Home, the distributed computing project that runs throughout the world to make one of the largest supercomputers in the world. The project is running large scale simulations on Protein Folds to try and cure diseases like Alzheimer’s, ALS, Huntington’s, Parkinson’s disease, and many Cancers.

So how can your server help, well I bet your server CPU’s hardly ever runs at a high load, otherwise you would be setting up faster processes and more servers, but it does seem wasteful having all these spare cycles just in case you get a surge in users. Well folding@home is clever it will never let your load average go much above 1.0 and if you start experiencing a surge in users folding@home will automatically throttle its CPU use, meaning your users will not be effected. So how do you install and run Folding@Home: Read the rest of this entry »

VPN: Cannot find Address

VPN is great, it enables us to securely connect to work from home or anywhere else, but there are often problems. I find the most common problem is that people can’t connect to a computer over VPN when the server address uses the same address scheme as the network their connecting form.

For example is you’re at home I bet your IP address is something like 192.168.0.3 and your gateway is 192.168.0.1, no problems there at all. But what happens if your VPN connection uses a similar address scheme, so your server address is something like 192.168.0.254. The problem happends because the first 3 numbers in a normal IP Address is used to identify the network and the last digit identifies the computer, if there are two networks with the same address i.e. 192.168.0 then how does your computer decide witch netowk to look at?

Setting up a Seedbox

Tutoiral Seed Torrentflux Logo torrent dataA seed box is a server for downloading and uploading digital files, commonly making use of the BitTorrent protocol. A common use for seed boxes is seeding torrents, it’s much more efficient to setup a Seedbox as it’s likely to have access to higher upload speeds. They are also good for general downloading, its easier to have a server running 24/7 then it is running your PC or Laptop all day. The ability to remote control seed boxes is a great advantage, it enables you to add and monitor downloads from anywhere, especially useful if someone recommends you something to watch at work.

In this tutorial I’m going to talk you through setting up a seed box designed for downloading torrents. I’m going to use TorrentFlux for this tutorial as it can easily be installed on a LAMP stack Read the rest of this entry »
