This article describes a method how to use a #USB memory device as an #authentication token to log in into a #Linux system instead of traditional #password. This can be accomplished by use of Pluggable Authentication Modules ( PAM ) and some sort of USB storage device such as USB memory stick of Mobile phone with SD card attached.

VeraCrypt is a free open source disk encryption software for Windows, Mac OSX and Linux. Brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a.
VeraCrypt main features:

Creates a virtual encrypted disk within a file and mounts it as a real disk.
Encrypts an entire partition or storage device such as USB flash drive or hard drive.
Encrypts a partition or drive where Windows is installed (pre-boot authentication).
Encryption is automatic, real-time(on-the-fly) and transparent.
Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
Encryption can be hardware-accelerated on modern processors.
Provides plausible deniability, in case an adversary forces you to reveal the password: Hidden volume (steganography) and hidden operating system.
More information about the features of VeraCrypt may be found in the documentation

After several years of trial and error, I finally have a complete RAW photography workflow in Linux that I am happy with.

The applications in this workflow aren’t just native to Linux, they are also free, open source software (FOSS). There is no need to dual boot, use WINE or a virtual machine. It’s a pure FOSS photography workflow running in Linux.

A thread on the Ubuntu-devel-discuss mailing list last month asked about how to find out what processes are making outgoing network connectsion on a Linux machine. It referenced Ubuntu bug 820895: Log File Viewer does not log "Process Name", which is specific to Ubuntu's iptables logging of apps that are already blocked in iptables ... but the question goes deeper.

Several years ago, my job required me to use a program -- never mind which one -- from a prominent closed-source company. This program was doing various annoying things in addition to its primary task -- operations that got around the window manager and left artifacts all over my screen, operations that potentially opened files other than the ones I asked it to open -- but in addition, I noticed that when I ran the program, the lights on the DSL modem started going crazy. It looked like the program was making network connections, when it had no reason to do that. Was it really doing that?

Esta edición, que acumula casi de 12 años de experiencias y trabajo, tiene un total de 680 páginas y corrige varios errores tipográficos, actualiza algunos procedimientos (relacionados con SELinux, principalmente) y otras mejoras menores. Salvo que haya algún error serio que corregir, o bien si se demora aún más el lanzamiento de CentOS 6, confío que esta sea la última edición basada sobre CentOS 5.
