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.

  • Linux disk resizing on Chromebooks pushed back to Chrome OS 78

    Back in March, I reported on an effort that would enable resizing of the Linux partition for Crostini-supported Chromebooks. At that time, I expected the feature to land in Chrome OS 75. I’ve checked for the feature now that Chrome OS 75 is available (again) and it’s nowhere to be seen. That’s because it was recently pushed back to Chrome OS 78. [...] However, other aspects need to be considered: Storage of large media files, for example, or enabling Google Drive synchronization with the Chrome OS Files app for offline file access. And then there are Android apps, so of which – particularly games – can require one or two gigabytes of space. So far, I haven’t run into any storage issues on my Pixel Slate with 128 GB of data capacity. But it’s easy to see that the Linux container is using up the bulk of my tablet’s storage: As I understand it, /dev/vdb is the Crostini container with Linux, which is 88 GB in size with 58 GB free.

Software: Maestral, GLava and Pitivi

  • Maestral Is A New Open Source Dropbox Client For Linux And macOS

    Maestral is a new open source Dropbox client for macOS and Linux, that's currently in beta. It can be used both with and without a GUI, and it was created with the purpose of having a Dropbox client that supports folder syncing to drives which use filesystems like Btrfs, Ext3, ZFS, XFS or encrypted filesystems, which are no longer supported by Dropbox.

  • GLava – OpenGL audio spectrum visualizer for desktop windows or backgrounds

    Over the past few months, I’ve written lots of reviews of open source audio software, focusing mainly on music players. Linux has a mouthwatering array of open source multimedia tools, so I’m going to turn my attention wider afield from music players. Let’s start with some multimedia candy. GLava is an OpenGL audio spectrum visualizer for Linux. An audio visualizer works by extracting waveform and/or frequency information from the audio and feeds this information through some display rules, which produces what you see on the screen. The imagery is usually generated and rendered in real time and in a way synchronized with the music as it is played. GLava makes a real-time audio visualizer appear as if it’s embedded in your desktop background, or in a window. When displayed as the background, it’ll display on top of your wallpaper, giving the appearance of a live, animated wallpaper. GLava is a simple C program that sets up the necessary OpenGL and Xlib code for sets of 2D fragment shaders. The software uses PulseAudio to sync the desktop visualizer with any music source.

  • Millan Castro: GSoC: First month working in Pitivi

    Pitivi is a video editor, free and open source. Targeted at newcomers and professional users, it is minimalist and powerful. This summer I am fortunate to collaborate in Pitivi development through Google Summer of Code. My goal is to implement an interval time system, with the support of Mathieu Duponchell, my menthor, and other members of the Pitivi community. An interval time system is a common tool in many video editors. It will introduce new features in Pitivi. The user will be able to set up a range of time in the timeline editor, playback specific parts of the timeline, export the selected parts of the timeline, cut or copy clips inside the interval and zoom in/out the interval. Mi proposal also includes the design of a marker system to store information at a certain time position.
