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..

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.

While being a huge fan of the GNU/Linux OS I do also live in the real world which means using Active Directory Domain Controllers and Windows networks. this week however I’ve had to build for a project a stand alone AD network. This got me thinking to a project I built for a school 6 uears ago which I did the same thing with Samba on Fedora.

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.

  • State of Linux Containers
    In this video from the Stanford HPC Conference, Christian Kniep from Docker Inc. presents: State of Containers. “This talk will recap the history of and what constitutes Linux Containers, before laying out how the technology is employed by various engines and what problems these engines have to solve. Afterward, Christian will elaborate on why the advent of standards for images and runtimes moved the discussion from building and distributing containers to orchestrating containerized applications at scale. In conclusion, attendees will get an update on what problems still hinder the adoption of containers for distributed high performance workloads and how Docker is addressing these issues.”
  • ONS 2018: Networking Reimagined
    For the past seven years, Open Networking Summit (ONS) has brought together the networking industry’s ecosystem of network operators, vendors, open source projects, leading researchers, and investors to discuss the latest SDN and NFV developments that will shape the future of the networking industry. With this year’s event, taking place March 26-29, 2018 in Los Angeles, ONS will evolve its approach as the premier open source networking event. We’re excited to share three new aspects of this year’s ONS that you won’t want to miss:
  • AT&T contributes code to Linux open source edge computing project
    The Linux Foundation recently announced a new project, dubbed Akraino, to develop an open source software stack capable of supporting high-availability cloud services for edge computing systems and applications. To kick off the project, AT&T will contribute code made for carrier-scale edge computing applications running in virtual machines and containers.
  • AT&T Brings Akraino Networking Project to Edge of the Linux Foundation
    The Linux Foundation has been particularly busy in 2018 thus far consolidating its existing networking project under a single umbrella, known as LF Networking. That umbrella might need to get a bit larger, as on Feb. 20 the Linux Foundation announced the new Akraino project, with code coming initially from AT&T.
  • FreeOffice 2016 – An Efficient Alternative to Microsoft Office
    FreeOffice 2016 is the latest version of the Office software from SoftMaker. In fact, you wouldn’t be wrong if you called it the free version of SoftMaker Office 2018 seeing as it features the same suite of applications.
  • Stellaris 2.0 'Cherryh' patch & Stellaris: Apocalypse expansion released, over 1.5 million copies sold
    Stellaris: Apocalypse [Steam], the latest expansion for the grand space strategy game from Paradox Development Studio is out. The big 2.0 'Cherryh' patch is also now available. Paradox has also announced today, that Stellaris has officially passed 1.5 million copies sold making it one of their most popular games ever made. I'm not surprised by this, as I consider Stellaris their most accessible game.

  • Getting Debian booting on a Lenovo Yoga 720
    I recently got a new work laptop, a 13” Yoga 720. It proved difficult to install Debian on; pressing F12 would get a boot menu allowing me to select a USB stick I have EFI GRUB on, but after GRUB loaded the kernel and the initrd it would just sit there never outputting anything else that indicated the kernel was even starting. I found instructions about Ubuntu 17.10 which helped but weren’t the complete picture. What seems to be the situation is that the kernel won’t happily boot if “Legacy Support” is not enabled - enabling this (and still booting as EFI) results in a happier experience.
  • Dell PowerEdge T30
    I just did a Debian install on a Dell PowerEdge T30 for a client. The Dell web site is a bit broken at the moment, it didn’t list the price of that server or give useful specs when I was ordering it. I was under the impression that the server was limited to 8G of RAM, that’s unusually small but it wouldn’t be the first time a vendor crippled a low end model to drive sales of more expensive systems. It turned out that the T30 model I got has 4*DDR4 sockets with only one used for an 8G DIMM. It apparently can handle up to 64G of RAM.
  • Quad-Ethernet SBC and controller tap new Renesas RZ/N1D SoC
    Emtrion’s Linux-ready “SBC-RZN1D” SBC, which will soon power a “Flex2COM” controller, features a Renesas dual-core -A7 RZ/N1D SoC and 4x LAN ports, and is designed for multi-protocol fieldbus communications. Emtrion, which recently announced its emCON-RZ/G1H module based on an octa-core Renesas RZ/G1H SoC, has unveiled a Renesas based, quad-LAN port SBC-RZN1D SBC focused on industrial communication. The SBC-RZN1D taps the Renesas RZ/N1D (R9006G032), one of a new line of RZ/N1D SoCs launched last year by Renesas for industrial multi-protocol communications. Renesas recently collaborated with Avnet to ship its own dual-Ethernet Renesas RZ/N1D Solution Kit (see farther below).
  • Postage-Stamp Linux
    There was a time when big operating systems ran on big iron. IBM, Data General, Burroughs, DEC, and other computer makers built big machines with big, blinking lights, and big price tags. They ran grown-up software and they supported multiuser operating systems. If you wanted a toy, you built a microcomputer. If you wanted a real machine for serious work, you bought a mainframe. Maybe a minicomputer, if it were for lesser tasks.

  • Radcom partners with Red Hat for NFV management
    Radcom announced it is collaborating with Red Hat to provide operators with a fully virtualized network visibility solution running on Red Hat OpenStack Platform. As operators transition to NFV, a critical first step is gaining end-to-end network visibility. This collaboration enables operators to attain cloud-native network visibility without the hassle of building their own private cloud infrastructure, the vendor said. Once the operator's transition to NFV matures, integration efforts with the NFV and MANO infrastructure can be simplified.

    In December, I received the happy news of an offer for a internship position at UNICEF in the Office of Innovation. The Office of Innovation drives rapid technological innovation by rapid prototyping of new ideas and building full-stack products to make a positive impact in the lives of children. This is a simple answer, but a more detailed description is on our website. My internship at UNICEF is unique: I support open source community engagement and research as my primary task for the MagicBox project. For years, I’ve done this in open source communities in my free time (namely SpigotMC and Fedora), but never in a professional role. As I navigate my way through this exciting opportunity, I plan to document some of the experience as I go through blogging. My intent is that my observations and notes will be useful to someone else in the humanitarian open source space (or maybe to a future me).

    DevOps, it has often been pointed out, is a culture that emphasizes mutual respect, cooperation, continual improvement, and aligning responsibility with authority. Instead of saying no, it may be helpful to take a hint from improv comedy and say, "Yes, and..." or "Yes, but...". This opens the request from the binary nature of "yes" and "no" toward having a nuanced discussion around priority, capacity, and responsibility.

We realized we had to convert the company in an open organization and start to work out in the open.

Boy was I wrong.

OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

    A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.

This fixes the Meltdown problems that affect most CPUs from Intel. Both Philip and Mike Larkin (mlarkin@) spent a lot of time implementing this solution, talking to various people from other projects on best approaches.

    In the commit message, Philip briefly describes the implementation [...]
