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

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.

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.

Security Leftovers

  • Microsoft & Pentagon are quietly hijacking US elections (by Lee Camp)
    Good news, folks! We have found the answer to the American rigged and rotten election system. The most trustworthy of corporations recently announced it is going to selflessly and patriotically secure our elections. It’s a small company run by vegans and powered by love. It goes by the name “Microsoft.” (You’re forgiven for never having heard of it.) The recent headlines were grandiose and thrilling: “Microsoft offers software tools to secure elections.” “Microsoft aims to modernize and secure voting with ElectionGuard.” Could anything be safer than software christened “ElectionGuard™”?! It has “guard” right there in the name. It’s as strong and trustworthy as the little-known Crotch Guard™ – an actual oil meant to be sprayed on one’s junk. I’m unclear as to why one sprays it on one’s junk, but perhaps it’s to secure your erections? (Because they’ve been micro-soft?)

Games: Project Zero Deaths, Littlewood, Ravenfield, ENCODYA

  • Project Zero Deaths, a new free to play online platform shooter has Linux support
    A free game to start the day with, as the multiplayer platform shooter Project Zero Deaths recently entered Early Access and it includes Linux support.
  • The peaceful building RPG 'Littlewood' is now available in Early Access with Linux same-day support
    Littlewood from developer Sean Young arrived on Steam in Early Access today and it looks like a very promising and peaceful RPG. Funded thanks to the help of nearly four thousand people on Kickstarter, Littlewood is set after the world has been saved and you're the hero tasked with rebuilding a town.
  • Ravenfield, the fun single-player FPS now has a built-in map editor and destructible object support
    The amount of content being added into Ravenfield is quite impressive and now anyone can easily make their own maps for it, without the need of Unity. Early Access Build 16 went live recently, with a custom-made map editor that works on Linux and it's surprisingly easy to use. You no longer need the Ravenfield mod tools for Unity, making it far more accessible. It comes with all of the official Ravenfield props, meaning you can place down all sorts of things. When ready, it also has Steam Workshop support built in for you to publish it.
  • Science Fiction point-and-click Encodya has a demo released, will go to Kickstarter
    The background story of the upcoming science fiction point and click game Encodya is the Kickstarter campaign for the animation short movie Robot Will Protect You. Getting over 23.000€ from an initial target of 8.750€, it reached several stretch goals, the last one being "We'll start developing a game!". And so they did... The game, named "ENCODYA", grabbed my attention in a Facebook group about point and click adventures. Drawn by the art, I asked if a Linux version would be possible. Indeed it was, and I was asked if I could test it. As it's using Unity, I expected it to a) fail on trying to play a video, b) show graphical problems or c) just run like the Windows version. First a) it was. But the author was eager to make the Linux version and a fix was attempted. After struggling with finding the right output options for the studio's intro video, we found that everything seems to be working just like on Windows. So Hooray for the game engines supporting the OS of our choice!

Graphics: Khronos Group, Radeon Software and Wayland Pains

  • Samuel Iglesias: My last VK-GL-CTS contributions
    Even if you are not a gamer, odds are that you already heard about Vulkan graphics and compute API that provides high-efficency, cross-platform access to modern GPUs. This API is designed by the Khronos Group and it is supported by a new set of drivers specifically designed to implement the different functions and features defined by the spec (at the time of writing this post, it is version 1.1).
  • Radeon Software for Linux 19.20 Brings RHEL 8.0 Support
    Quietly released last week was Radeon Software for Linux 19.20, the latest quarterly update to AMD's packaged Linux driver that consists of their AMDGPU-PRO binary driver option as well as the AMDGPU-Open packaged components using a snapshot of Mesa. Radeon Software for Linux 19.20 only has a sole change listed: Red Hat Enterprise Linux 8.0 support and any other binary compatible downstream like the yet-to-be-released CentOS 8.0. That's it in terms of the official changes but should be also pulling in a newer snapshot of Mesa and their binary OpenGL/Vulkan drivers, newer DRM kernel driver code, etc.
  • Konsole and Wayland
    Wayland needs a different mindset when you are programming, you cannot just assume things works the same way as in as X11. One of my first patches to konsole was the rewrite of the Tab Bar, and a different way to deal with Drag & Drop of the tabs. In my mind - and how wrong I was - I could assume that I was dragging to a konsole main window by querying the widget below the mouse. Nope, this will not work. As Wayland has security by default, it will not give you anything global. What if I was a spy app trying to record another one to send to NSA? Security in Wayland is much stricter, and because of that I had to redo my drag & drop patch.
