Prevent Phishing with Mutual Authentication

Phishing is a man-in-the-middle attack. While many people think using time-bound, one-time passwords will solve the problem, they are wrong as attacks will just become automated. What is required is strong mutual authentication - authentication of the host to the user as well as the user to the host. This article demonstrates how to do that using open-source software from WiKID.

Convert Physical Windows Systems Into Virtual Machines To Be Run On A Linux Desktop

Run Your Own Webradio Station With Icecast2 And Ices2

Setting up a serial console

This tutorial will show you how to set up a serial console on a Linux system, and connect to it via a null modem cable. This is quite useful if your Linux server is in a headless configuration (no keyboard or monitor), as it allows you to easily get a console on the system if there are any problems with it (especially network problems, when SSH is not available). In the end, the GRUB menu will appear over the serial link, as will the bootup messages (output when booting the system). I'm using Debian Etch on the server and Ubuntu Edgy on my client, although this should work on any Linux distribution.
