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…

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..

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.

Linux Foundation: OpenContrail, SDNs, ONAP

  • Juniper Flips OpenContrail To The Linux Foundation
    It’s a familiar story arc for open source efforts started by vendors or vendor-led industry consortiums. The initiatives are launched and expanded, but eventually they find their way into independent open source organizations such as the Linux Foundation, where vendor control is lessened, communities are able to grow, and similar projects can cross-pollinate in hopes of driving greater standardization in the industry and adoption within enterprises.
  • Juniper Hands OpenContrail SDN to Linux Found. Before It's Too Late
    After failing to develop a community around the project and receiving pushback from a major backer, Juniper may be saving Contrail from becoming irrelevant
  • CableLabs Announces Two Open Source Projects for NFV
    SNAPS is an overarching program at CableLabs to facilitate the adoption of software-defined networking (SDN) and network functions virtualization (NFV) within the CableLabs’ community. The organization says it spearheaded SNAPS to fill in gaps within open source to ease the adoption of SDN and NFV for its cable members.
  • Bell becomes first operator to launch ONAP in production
    Canadian telecommunications company Bell announced it has become the first company to launch an open source version of the Open Network Automation Platform (ONAP) in production. The announcement was noted by Arpit Joshipura, general manager of networking and orchestration at the Linux Foundation, in a company blog post. According to Joshipura, the news marks a first step toward using ONAP as a common platform across Bell’s network as the company re-aligns itself to follow a multi-partner DevOps model.

  • When Waze Won't Help, Palestinians Make Their Own Maps
    If you want to drive the 15 or so miles from Jerusalem to the city of Jericho, in the Palestinian Territories, Google Maps will tell you: “Can’t find a way there.” Waze will issue a warning: “Caution: This destination is in a high risk area or is prohibited to Israelis by law.” If you press “Confirm Drive” nonetheless, the app will direct you, just not all the way. When you pass from Israel into the West Bank, part of the occupied Palestinian Territories, Waze’s directions simply end. To keep going, you need to change your setting to allow access to “high risk” areas. Even then, GPS coverage tends to be limited.
  • Using Gmail with OAUTH2 in Linux and on an ESP8266
    One of the tasks I dread is configuring a web server to send email correctly via Gmail. The simplest way of sending emails is SMTP, and there are a number of scripts out there that provide a simple method to send mail that way with a minimum of configuration. There’s even PHP mail(), although it’s less than reliable.
  • Simplicity Before Generality, Use Before Reuse
    A common problem in component frameworks, class libraries, foundation services, and other infrastructure code is that many are designed to be general purpose without reference to concrete applications. This leads to a dizzying array of options and possibilities that are often unused or misused — or just not useful. Generally, developers work on specific systems; specifically, the quest for unbounded generality rarely serves them well (if at all). The best route to generality is through understanding known, specific examples, focusing on their essence to find an essential common solution. Simplicity through experience rather than generality through guesswork.
  • What Ruby Needs
    Of all of the questions we receive at RedMonk, one of the most common concerns programming languages. Whether from members of a given community or a commercial entity, the desire is to better understand a given language’s trajectory and the context around it. Is it going up or down, and what are the reasons for that direction? And, of course: can that direction be meaningfully changed? Recently, we’ve received several such inquiries around Ruby. For those with an interest in the language, then, the following is a quick public summary of the answers we’ve been providing privately.
  • HTML 5.2 is done, HTML 5.3 is coming
    Today W3C releases HTML 5.2. This is the second revision of HTML5, following last year’s HTML 5.1 Recommendation. In 2014 we expressed a goal to produce a revision roughly every year; HTML 5.2 is a continuation of that commitment. This Recommendation like its predecessor provides an updated stable guide to what is HTML. In the past year there has been a significant cleanup of the specification. We have introduced some new features, and removed things that are no longer part of the modern Web Platform, or that never achieved broad interoperability. As always we have also fixed bugs in the specification, making sure it adapts to the changing reality of the Web. Many of the features added integrate other work done in W3C. The Payment Request API promises to make commerce on the Web far easier, reducing the risks of making a mistake or being caught by an unscrupulous operator. New security features such as Content Security Policy protect users more effectively, while new work incorporated from ARIA helps developers offer people with disabilities a good user experience of their applications.
