Getting Squid3 on Debian 6.x to work with Active Directory, Security Groups and Websense

Filed under
Linux

I’ve had a need to get a local squid proxy to perform local filtering based on AD Security groups because it’s not something websense can do. I found this wonderful howtofoge guide online and Used it to setup the base system. This howto is a work in progress as the next stage is to get it working with DansGuardian or SquidGuard.

Prerequisites
Client Internet Explorer Browsers need to have “Enable Integrated Windows Authentication” ticked in Internet Options :: Advanced settings as well as Proxy Auto detection enabled – google these if not sure. All modern web browsers will support proxy auto detection. Firefox and Chrome also support Windows Authentication.

Enabling Dual Factor Authentication on Linux SSH logins..

Filed under
Linux

A couple of weeks ago I wrote a post on using a Chromebook to develop on a cloud platform. Its based on a Digital Ocean remote server and like most people who wish to attach to the command line interface on a remote server I use SSH. It’s an encrypted connection over the network/internet from end to end. However being a cloud server I was wondering if it was possible to secure this a little bit more?

A chat with a friend on the way into work provided me with a solution.

The solution is Two Factor authentication a system beased on a simple premise, something you know (the SSH password in this case) and something you have (your mobile phone in this case, but it could be a secure token) which will deliver a random number.

Using a Chromebook to develop in the cloud…

Filed under
Linux

Being a few months in with my Acer C7 Chromebook as my only laptop i’ve very pleased with what it does, I do have the Crouton Ubuntu chroot installed and upgraded the device to 16Gb of Ram, however there is one core thing I miss with this setup. VMWare/Virtualbox. I find i’m often building virtual machines, usually Ubuntu to test bsh scripts or build LAMP Environments to test some PHP out with. That isn’t something i’m able to do even on the CHROOT Ubuntu environment.

All however is not lost, and i’ve found a way to get round this..

They say a week in politics is a long time, well a year in the mobile phone industry is an eternity and what huge changes the industry is going through. A year ago the roost was ruled by Apple and Google, 3G was the fastest we can go and handsets were finding a stock size at 4.5″.. The world however of the mobile device is now a very different place and very much in a positive state of change..

Casual Programming and Linux Screen-Recorders

Linux

After being retired (for four years) from teaching high school Computer Science, I decided to get back into programming again. I once taught a beginning programming class using the Ruby language, and I thought that would be a good way to get back into programming. So, I decided I needed a “Ruby refresher”, and I wanted to learn more about that language than I taught in the classroom.

The EE Nokia Lumia 920

The UK got its first 4G network this month and the choices for 4G phones are thin on the ground at the moment the iPhone 5 and the Samsung Galaxy S3 were there at launch however as a long time Android and IOS user i’m finding both operating systems at that stage of their life when they ar about features not innovation. This may well change in the future however, and you must understand these words are hard for me to say, Microsoft seem to be innovating quite a bit in the OS market, pushing the boat out and taking some risks.

My phone of choice on EE is the Nokia Lumia 920, Nokias last bi breath attempt at staying alive as a company it would seem however this is a phone developed for Windows Phone 8 in Microsoft. It is the phone Microsoft were happy to share the stage with at launch and it’s got generally good reviews.

Lets start this with the two important things the phone and the 4G..

Building your own cloud using OwnCloud on Ubuntu.

Filed under
Linux

Unless you’ve been under a rock or are the type of Luddite who thinks the pen and paper is modern hi tech, you cannot fail to have heard about the most miss used expression on the Internet, the cloud. It’s a buzzword which every ill equipped marketing goon has latched his crayon’s onto and will mention in every presentation ever.

Put simply the cloud is the image used when tech people wanted to display the Internet outside their own network, this turned into a location firstly where data could be stored and more recently where “Big Data” is stored.. Honestly I have no idea who comes up with this stuff.

We know the mobile phone is where it is at, we also know the cloud is the glue which binds all our devices, what if this didn’t have to be the case? The cloud is great when you are tethered to your Wifi or a mobile signal, great if you work in a big city with lots of Wifi hotspots or mobile coverage. Not so good when the office blocks access to it because of security risks, or you live in a 3G blackspot.

Open Source in 3-D Printing

  • 17,000% Cost Reduction with Open Source 3D Printing: Michigan Tech Study Showcases Parametric 3D Printed Slot Die System
    We often cover the work of prolific Dr. Joshua Pearce, an Associate Professor of Materials Science & Engineering and Electrical & Computer Engineering at Michigan Technological University (Michigan Tech); he also runs the university’s Open Sustainability Technology (MOST) Research Group. Dr. Pearce, a major proponent for sustainability and open source technology, has previously taught an undergraduate engineering course on how to build open source 3D printers, and four of his former students, in an effort to promote environmental sustainability in 3D printing, launched a business to manufacture and sell recycled and biodegradable filaments.
  • Open Source 3D printing cuts cost from $4,000 to only $0.25 says new study
    Slot die coating is a means of adding a thin, uniform film of material to a substrate. It is a widely used method for the manufacturing of electronic devices – including flat screen televisions, printed electronics, lithium-ion batteries and sensors. Up until recently, slot die components were only machined from stainless steel, restricting development and making the process expensive. Now slot dies for in-lab experimental use can be made on a 3D printer at a fraction of the cost.
  • Dutch firm unveils world's first 3-D-printed propeller
    Three-dimensional (3-D) printing technology has caught the logistics world's attention for its potential to save on warehouse and shipping costs by producing items on demand at any location. In the past two years, for example, UPS Inc. announced plans to partner with software developer SAP SE to build a nationwide network of 3-D printers for use by its customers, and General Electric Co. spent nearly $600 million to buy a three-quarters stake in the German 3-D printing firm Concept Laser GmbH. Recently, transportation companies have begun turning to the same technology for another application, creating the actual hardware used in vehicles that move the freight. For instance, in late 2016, global aircraft maker Airbus S.A.S. contracted with manufacturing firm Arconic Inc. to supply 3-D printed metal parts for its commercial aircraft.
