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..

The EE Nokia Lumia 920

Just talk

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.

While being a huge fan of the GNU/Linux OS I do also live in the real world which means using Active Directory Domain Controllers and Windows networks. this week however I’ve had to build for a project a stand alone AD network. This got me thinking to a project I built for a school 6 uears ago which I did the same thing with Samba on Fedora.

Filed under
Linux

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.

Graphics: DXVK, Nouveau

  • DXVK 1.4 Released With Updates Against Direct3D 11.4, Other Improvements

    In time for any weekend gaming is the release of DXVK 1.4 as the latest big update to this Direct3D 11 over Vulkan implementation to boost the D3D11 Windows gaming performance with the likes of Wine and Valve's Steam Play (Proton). With DXVK 1.4 the Direct3D interfaces have been updated against D3D11.4, the latest D3D11 revision shipped by Windows 10 Build 1903. This update brings new API features but DXVK isn't yet supporting some of the optional features like tiled resources and conservative rasterization.

Noctua NH-L9a-AM4: A Very Low-Profile AMD Ryzen Cooler

At just 37mm tall, the Noctua NH-L9a-AM4 is one of the shortest yet quite capable CPU heatsink fans we have seen yet for AMD Ryzen processors. When looking for a heatsink with a small stature for an AMD APU mini PC build for HTPC / file storage use-cases (more on that build in the next day or two), the Noctua NH-L9a-AM4 fit the criteria and so I went with that given the success with the many Noctua heatsinks we have used over the years. For those potentially interested in the NH-L9a-AM4 for an AMD APU like the new Ryzen 5 3400G or for lower-end Ryzen CPUs, I ran some benchmarks with this cooler. Read more

    Software teams seeking to provide better products and services must focus on faster release cycles. But running reliable systems at ever-increasing speeds presents a big challenge. Software teams can have both quality and speed by adjusting their policies around ongoing service ownership. While on-call plays a large part in this model, advancement in knowledge, more resilient code, increased collaboration, and better practices mean engineers don't have to wake up to a nightmare. This four-part series will delve into the concepts of full-service ownership, psychological safety in transformation, the ethics of accountability, and the impact of ownership on the customer experience.

  • Simple rules of good programming

    Hi guys, I work as a programmer for more than 15 years and was using many different languages, paradigms, frameworks and other shit. And I want to share with you my rules of writing good code. [...] Code review can be as good as it can be bad. You can organize code review only if you have a developer who understand 95% of the code and who can monitor all updates without wasting to much time. In another situation, it will be just time consuming and everyone will hate this. On this part got too many questions so describe this more deeply. Many people think that code review it’s a good way of teaching new guys, or teammates who work on a different part of code. But the main target of code review it’s maintaining code quality, and not teaching. Let’s imagine that your team making code for controlling a cooling system for nuclear reactor, or space rocket engine. And you made huge mistake in very hard logic, and then you are giving this for code review to the new guy. How do you think what would be the risk of an accident? — On my practice more than 70%. A good team is where each person has own role and responsibility for the exact piece of work. If someone wants to understand another piece of code then he goes to a person responsible for it and asks her. Impossible to know everything and better excellent understand a small piece of code than all but on 30%.

  • Intellectual property Law and Coding

    In the world of software, good code is a necessity, and great code can make the difference between a startup succeeding and failing. But how do you protect coding innovations that may be novel or unique? Intellectual property law, or IP law, is the main legalistic framework that can answer many of those questions and more. Any business, and perhaps more crucially, any individual coder, should be aware of their options when it comes to maintaining the rights to their work. Here, we delve into some of the most important things to know about IP law and coding.
