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.

Most of the guides you will see using this utility mine included cover how to get Ubuntu 12.04 the LTS version working, however there is also scope within the command line to get the latest and greatest up and running. specifically the -r switch. Issuing the following command will provide you with a bare bones Ubuntu 13.04 install

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..

There’s something Ubuntu needs to do if the phone is going to work..

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..

What does the Ubuntu Phone need to succeed?

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.

Maybe it's time to think about LTSP?

With austerity being the watchword of our times being able to get as much out of that IT hardware you have is as important as ever, more so when the industry is in shift at an OS level and maybe the hardware you have isn’t quite up to the task of Windows 8?

Ubuntu Phone, Good idea?

In a bold move today Ubuntu have announced plans to move forward with an Ubuntu Phone which it is touting the interface is the difference here. This is a big statement in a marketplace which has been owned by Apple and Google for the last 3 to 4 years.

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.

  • Updating POSIX
    To the first point, many people seem unaware that POSIX is an actual set of standards - IEEE 1003.1 in several variations, plus descendants. These standards cover a lot more than just operations on files, and technically "POSIX" only refers to systems that have passed a set of conformance tests covering all of those. Nonetheless, people often use "POSIX" to mean only the section dealing with file operations, and only in a loose sense of things that implement something like the standard without having been tested against it. Many systems, notably including Linux, pretty explicitly do not claim to comply with the actual standard.
  • Delete Your Dead Code!
    A few days ago, Ned Batchelder's post on deleting code made the rounds on HN, even though it was originally written in 2002. Here I want to echo a few of Ned's points, and take a stronger stance than he did: delete code as soon as you know you don't need it any more, no questions asked. I'll also offer some tips from the trenches for how to identify candidate dead code. This is the first in a series on eating your vegetables in software engineering, on good, healthy practices for a happy and successful codebase. I don't (yet) know how long the series will be, so please stay tuned!

    The problem is that the OS will automatically run a program that can install malware from a USB stick.

    The domain is used by crooks to infect visitors with malware that lets the attackers gain full control of the infected Windows computer.
  • Slack bot token leakage exposing business critical information
    Developers are leaking access tokens for Slack widely on GitHub, in public repositories, support tickets and public gists. They are extremely easy to find due to their structure. It is clear that the knowledge about what these tokens can be used for with malicious intent is not on top of people’s minds…yet. The Detectify team shows the impact, with examples, and explains how this could be prevented.

Debian and Devuan

  • An Open Letter to Linas Vepstas
    The entire essay continues on a similar note. Although the title implies this is a rant about Ubuntu and Debian, he seems to paint the entirety of Linux Land with the same broad brush. And that would be factually wrong. "Factually wrong" doesn't mean he hasn't pointed out some serious problems. He has. I and many other Linux users see the same problems he identifies. What's "factually wrong" is that these problems are built into the combination of kernel, system software, and applications generally called either "Linux" or "GNU/Linux". And his implication that there's no reasonable way for a user to avoid these problems is also factually wrong. The bottom line of my objection to his essay is this: Nobody should use software they don't like, especially if there's a reasonable alternative. And by extension, why is Linas still using Debian and Ubuntu and systemd and Firefox and Chrome and Gnome? There are reasonable alternatives to every single one of them.
