Recent versions of Ubuntu are shipping with Snapcraft by default, and some of the default applications run inside a snap as well. Snaps are application containers, similar to Docker, but designed for desktop applications. Unfortunately Canonical seems to be pushing Snaps hard, and they are not always wanted. This is made worse by not providing an easy way to remove the snap functionality for Ubuntu. The commands bellow will entirely remove snap from an Ubuntu installation....

For those of you not in the know, ambergris is defined as: a wax-like substance that originates as a secretion in the intestines of the sperm whale, found floating in tropical seas and used in perfume manufacture. However, that will not be what this post is about (sorry to disappoint). Instead, I’ll present what happens when building an image on Docker that contains a reverse shell in the Dockerfile. Docker First, let me start with a very brief description of Docker....

A while ago I was working on building a custom kernel for my Android phone. Once you get the source the compilation process is not as straightforward as I hoped. Here are the steps required to get from the kernel source to a flashable image for your phone. Get a copy of the build toolchain and Linux kernel for your device First download a copy of the pre-build toolchain from git....

By default CrunchBang Linux does not have hibernation support enabled in the shutdown menu. The reason for being excluded is likely because not all computers support hibernation. However most modern computers will support it. To add a hibernation option just download this file and place it in the bin directory of your home folder: “~/bin/” and make it executable with: chmod +x cb-exit cb-exit Gist If you want to test your system to see if it can handle hibernation run the following command....

This is about a piece of software I wrote over a year ago to fit a need I had at the time. It probably will not receive any updates but I have released the source to anyone is free to do as they please with it. Background PHPRepo is a PHP CMS for managing Debian package repositories. A while ago I wanted to start my own repository for some of my own packages, so I looked for an easy way to do this....

This is a minimalistic how-to to get a Debian environment running on almost any (rooted) android phone. I adopted the method here: http://www.saurik.com/id/10 to be more universal and added some new features. Preparing the Debian Image You will need access to a computer dunning a Debian based distribution to create the image for you phone. I used Ubuntu 10.04. To create the image you need to install a program called debootstrap....

This is a simple how-to on using Microsoft’s Active Directory for user authentication on Linux systems. The method described in this guide should work for Cent OS, Red Hat Enterprise Linux (RHEL), and Fedora. Debian based distributions do not the the tools used in this method and require a different setup. This guide used Cent OS 5.5 with a minimal text only install, however it should apply the same to other compatible versions of Linux....

PXE is a method for booting an operating system over a network, it stands for Pre-Executable environment. Here I will show you how to build a PXE server to boot and or install operating systems over your network. Installing the server OS I made this server inside VMWare, however the steps are the same if you are using a different virtual machine server or a physical machine. I used Debian 5....

This guide will tell you how to rename or switch network controller names in Linux. Often when installing Linux the installer will automatically pick the names of the network controllers. And for some reason the order it names them is almost always not the order I want them in. I usually like the primary/on-board card eth0, and all additional cards eth1-n, however the installer often has its own ideas. So this is how to correct it!...

Part 1 - Screen Screen is a program that can create virtual terminals inside your current session. If you are used to a tabbed web browser you can think about it as adding tabs to your terminal. And if your server allows it can allow you to disconnect sessions and keep then running in the background, even if you log out. You can install screen on Debian with apt-get by running sudo apt-get install screen and yum install screen for rpm based systems....
