18.05.12: Create And Restore Partition Images With Partimage

Create And Restore Partition Images With Partimage

Backups are usually made in one of two ways - either file-based which means that single files are backed up, often via synchronization and on an external disk, or image-based which means that a whole partition is stuffed into an image file that can be restored on the partition, containing everything there was on it. This tutorial covers image-based backups using Partimage from a live desktop environment.

16.05.12: How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04

How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04

This document describes how to add WiKID two-factor authentication to Apache 2.2.22 using mod_auth_radius on Ubuntu 12.04. It is also recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.
