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.

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.

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.

In a Quiet Market for PCs, Chromebooks are Marching Steadily Forward

It's no secret that Chrome OS has not been the same striking success for Google that the Android OS has been. And yet, Chromebooks--portable computers running the platform--have not only found their niche, but they are also introducing a new generation to cloud computing. Chromebooks are firmly entrenched in the education market, where many young users have become used to the convention of storing apps and data in the cloud. Now, according to new research from Gartner, Chromebooks are ready to hit new milestones. Analysts there report that Chromebook shipment growth will be in the double digits this year. At the same time, though, Chromebooks have not become fixtures in the enterprise, replacing Windows PCs. Read more

Server Administration

  • SysAdmins With Open Source Skills Are In Demand
    System administrators play a crucial role in businesses today. They are the individuals responsible for the configuration, support and maintenance of company computer systems and servers. For this reason, they are a popular hiring request, with defense and media companies alike looking for these professionals on Dice. Yet, despite the ongoing demand, finding and recruiting system administrators may be more of a challenge. Data from the U.S. Bureau of Labor Statistics (BLS) found that the quarterly unemployment rate for system administrators was 0.6%, well below the national quarterly average (4.9%) and the quarterly average for all tech professionals (2.1%). Employers thus need to focus more of their recruitment strategies on poaching this talent from competitors.

  • 5 reasons system administrators should use revision control
    Whether you're still using Subversion (SVN), or have moved to a distributed system like Git, revision control has found its place in modern operations infrastructures. If you listen to talks at conferences and see what new companies are doing, it can be easy to assume that everyone is now using revision control, and using it effectively. Unfortunately that's not the case. I routinely interact with organizations who either don't track changes in their infrastructure at all, or are not doing so in an effective manner. If you're looking for a way to convince your boss to spend the time to set it up, or are simply looking for some tips to improve how use it, the following are five tips for using revision control in operations.
