anon-hotspot: On demand Debian Linux (Tor) Hotspot setup tool

September 18, 2016

Today it’s not easy to anonymize internet traffic and protect our online privacy. From advertisers to various other parties, everyone seems to be interested in what we’re doing online, and it’s our traffic that allows them to track our behaviour and interests.

To make our internet traffic anonymous we could turn to various VPN/Proxy solutions, but in the end need you still need to have ultimately trust that your traffic on other side of the tunnel won’t end up in wrong hands.

That’s why if I want anonymity I’ll always turn to Tor (anonymity network).

Turn Raspberry Pi 3/or any other Debian Linux based device into a (Tor) WiFi Hotspot

You need two things:

  1. Clone anon-hotspot git repo
  2. Raspberry PI 3 or any other Debian Linux based device with ethernet port and wifi card

Kernel agnostic, DisplayLink Debian GNU/Linux driver installer (Debian/Ubuntu/Elementary)

32
November 29, 2015

I use DisplayLink at work for multi display setup/Ethernet/etc, all by connecting to a single USB port. Although it’s a nifty little device, its software support isn’t that great.

Only Linux driver they have is for Ubuntu. Which is only optimized to work with 14.04, and latest kernel they support is 3.19!

Their installer script can be modified to work with Debian and Systemd, but even so if you’re using any Linux kernel version other then >=3.14 && <=3.19 you’re not going to have a good time.

That’s why I decided to take things in my own hands, and created displaylink-debian.

Tool which allows you to seamlessly install and uninstall DisplayLink drivers on Debian/Ubuntu based Linux distributions.

Juniper/Pulse Secure VPN on Linux (2015 edition)

September 21, 2015

Prelude

Some time ago, Juniper Networks sold their beloved Junos Pulse SSL VPN, and thus new company called Pulse Secure was created. Which resulted in Pulse Secure client, which is used to establish secure authentication to the (VPN) tunnel.

Since Juniper never supported Linux, it comes as no surprise that successor company client supports every other platform except Linux.

Setting Juniper VPN/Secure Pulse on Linux is pain. Basically, it comes down to using Java applet in web browser or using 3rd party hacks and scripts. Something I refused to accept.

Getting it to work in a web browser

Although, it can be bit confusing on 64 bit architecture, getting VPN access via web browser is simple. You just need to install right packages:

sudo apt-get install icedtea-7-plugin openjdk-7-jre:i386 libstdc++6:i386 lib32z1 lib32ncurses5 libxext6:i386 libxrender1:i386 libxtst6:i386 libxi6:i386

Debian PPA Utility

September 4, 2014

Debian remains to be my favorite distribution, however there’s one thing that’s missing, that thing is called PPA.

There were numerous discussions on this topic inside of Debian, but AFAIK without any visible movement. Thus, I decided to publish a utility I’ve been using for some time now.

PPA’s

Since its introduction, PPA’s are exclusively connected to Ubuntu and its derivatives (Mint, Elementary, etc …). But over time, a number of interesting projects appeared whose whole development is happening inside of PPA’s. To name few, I’m talking about TLP, Geary, Oracle Java Installer, Elementary OS and etc … Some of these projects are in WNPP without much happening for a long time, i.e: TLP

One option was to repackage these packages and then have them uploaded to Debian, or just go rogue and install them directly from its PPA’s. Title of this post might hint which path I took.

In theory, adding Ubuntu packages on your Debian system is a bad idea, and adding its PPA’s is probably even worse. But, I’ve been using couple (TLP, Geary, couple of custom icon sets) of these PPA’s on my personal/work boxes, and to be honest, never had a single problem. Also, setting Pinning priority to low for the PPA you added is never a bad idea.

Taking control over Debian and its package repositories

October 29, 2013

When we talk about Debian we must talk in the superlative. One of the reasons why Google and International Space Station are choosing Debian as their default Linux distribution is because it has (by far) the biggest package collection. At the time of writing this document, there are 61801 packages in Debian Sid (Unstable/Development distribution).

But as with many things in life, your greatest asset can be also your biggest liability—unless you take things under control. As an example, people usually complain how package versions in Debian “Stable” are too old, and they are spot on right ignorant. The author of this document has never used Debian “Stable” outside of production and has solely relied on some of the ingenious mechanisms provided by Debian, which when properly configured can provide you with unlimited possibilities.

APT Pinning

Pinning allows you to install and run package versions from other (Testing/Unstable/Experimental) Debian branches without having to upgrade the whole distribution to that particular branch.

Example 1:

You are running Debian 7.2 (Wheezy), and you want latest “libjmagick6-java” version (i.e: 6.6.9), however you only see the version which is present in Stable repository (6.2.6). When you look for the package on Debian packages, you can see that the version you want is present in Testing/Unstable.
