How to Create VLAN Trunking on Cisco Catalyst Switch – If you have multiple switches that are part of a stack, then any VLAN you create on the master switch is available on all the switches in the stack. However, if you have multiple switches that are not part of stack, and if you need to use the same VLAN between these two switches, you need to use VLAN trunking. This tutorial explains how to configure VLAN trunking between two different switches.
FBI Tor Malware Analysis – [...] In April 2013, a piece of malware was found embedded in Freedom Hosting's darknet server that would exploit a security hole in a particular web browser and execute code on the user's computer.

A Gentoo Linux Advanced Reference Architecture – The book "A Gentoo Linux Advanced Reference Architecture" is meant as a resource displaying the powerful features of many free software solutions that are supported on top of Gentoo Linux. It is a deep-dive approach in many aspects related to processes, supportability, maintainability based on Gentoo Linux system deployments. Unlike the existing, per-application documents that exist on the Internet (and which are a valuable resource to get into the gory details of many applications) and the per-distribution guides that provide information on using that particular distribution, this book will focus more on architecturing IT infrastructure for medium-sized enterprises. Smaller enterprises might find the reference architecture here too expensive or large – however, many services described in the book can be slimmed down into a smaller deployment as well.
