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..

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.

    Many programmers are moving towards data science and machine learning hoping for better pay and career opportunities --- and there is a reason for it. The Data scientist has been ranked the number one job on Glassdoor for last a couple of years and the average salary of a data scientist is over** $120,000** in the United States according to Indeed. Data science is not only a rewarding career in terms of money but it also provides the opportunity for you to solve some of the world's most interesting problems. IMHO, that's the main motivation many good programmers are moving towards data science, machine learning and artificial intelligence.

  • Find the smallest number within a list with python

    In this example, we will create a python function which will take in a list of numbers and then return the smallest value. The solution to this problem is first to create a place holder for the first number within the list, then compares that number with other numbers within the same list in the loop. If the program found a number which is smaller than the one in the place holder, then the smaller number will be assigned to that place holder.

  • Basic Input, Output, and String Formatting in Python

    To be useful, a program usually needs to communicate with the outside world by obtaining input data from the user and displaying result data back to the user. This tutorial will introduce you to Python input and output. Input may come directly from the user via the keyboard, or from some external source like a file or database. Output can be displayed directly to the console or IDE, to the screen via a Graphical User Interface (GUI), or again to an external source.

Almost every time I have a question, I find that someone on Stack Overflow has asked it, and that people have answered it, often in great detail. I’m thus not against Stack Overflow, not by a long shot. But I have found that many Python developers visit there 10 or even 20 times a day, to find answers (and even code) that they can use to solve their problems.

  • Introducing pytest-elk-reporter

    Few years back I’ve wrote a post about how I’ve connected python based test to ELK setup - “ELK is fun”, it was using an xunit xml, parsing it and sending it via Logstash. Over time I’ve learn a lot about ElasticSearch and it’s friend Kibana, using them as a tool to handle logs. and also as a backend for a search component on my previous job. So now I know logstash isn’t needed for reporting test result, posting straight into elasticsearch is easier and gives you better control, ES is doing anything “automagiclly” anyhow nowadays.

  • OpenStack Stein feature highlights: vGPU support coming in Red Hat OpenStack Platform 15

    Red Hat is working on the next release of the supported enterprise distribution of OpenStack, Red Hat OpenStack Platform 15, based on the Stein community release. In this multi-part blog series, we’ll be examining some of the features that Red Hat and the open source community have collaborated on–starting with a look to future workloads, such as artificial intelligence. "How does OpenStack enable next generation workloads?" you ask. When it comes to computer-driven decision making, machine learning algorithms can provide adaptable services that can get better over time. Some of these workloads, such as facial recognition, require GPUs to ingest and process graphical data in real time. But the more powerful GPUs often used for machine learning and such are expensive, power-hungry, and can take up a lot of room in the servers' chassis. When working with GPUs at scale, optimized utilization is key to more cost effective machine learning.

    Vulkan 1.1.112 was outed this morning as the newest documentation update to this high performance graphics and compute API. Vulkan 1.1.112 is quite a mundane update with just documentation corrections and clarifications this go around and not any new extensions. But at least the clarifications should help out some and other maintenance items addressed by this Vulkan 1.1.112 release. It's not a surprise the release is so small considering Vulkan 1.1.111 was issued just two weeks ago.
