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

Filed under
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.

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.

  • What makes a great Open Source project?
    Recently the Document Foundation has published its annual report for the year 2015. You can download it as a pdf by following this link, and you can now even purchase a paper copy of the report. This publication gives me the opportunity to talk a bit about what I think makes a great FOSS project and what I understand may be a great community. If it is possible to see this topic as something many people already went over and over again, think again: Free & Open Source Software is seen as having kept and even increased its momentum these past few years, with many innovative companies developing and distributing software licensed under a Free & Open Source license from the very beginning. This trend indicates two important points: FOSS is no longer something you can automagically use as a nice tag slapped on a commodity software; and FOSS projects cannot really be treated as afterthoughts or “nice-to-haves”. Gone are the days where many vendors could claim to be sympathetic and even supportive to FOSS but only insofar as their double-digits forecasted new software solution would not be affected by a cumbersome “community of developers”. Innovation relies on, starts with, runs thanks to FOSS technologies and practices. One question is to wonder what comes next. Another one is to wonder why Open Source is still seen as a complex maze of concepts and practices by so many in the IT industry. This post will try to address one major difficulty of FOSS: why do some projects fail while others succeed.

    A few days after he mused that there had been no reason for him to blow his stack recently, Linux creator Linus Torvalds has directed a blast at the Software Freedom Conservancy and its distinguished technologist Bradley Kuhn over the question of enforcing compliance of the GNU General Public Licence. Torvalds' rant came on Friday, as usual on a mailing list and on a thread which was started by Software Freedom Conservancy head Karen Sandler on Wednesday last week.
