When faced with making Linux and Windows work together securely, system administrators can run into trouble if they don't understand or can't correctly use the administrative security controls that are present in the Microsoft Windows operating system (OS) and the Samba-3 equivalents of those controls.

You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks.
Last month I introduced the ABC music notation system. This month, I continue our tour of notation programs for Linux with a look at the Common Music Notation system from composer/programmer Bill Schottstaedt.
In the simplest terms, netcat is a utility that reads and writes data across the network. Here then is an introduction to netcat for Linux users who may not be familiar with the "TCP/IP Swiss Army knife."
This document describes an easy way to automate Apt updates based on a Debian Sarge box.
Do you spend a lot of time moving around the filesystem with cd commands, typing ls to see what’s there? Do you build lists of arguments on the command line using wildcards or filename completion? If you do a lot of work with files and directories, vshnu is worth a look.

This tutorial provides step-by-step instructions on how to install Xen (version 2) on a Debian Sarge (3.1) system. It should apply to Ubuntu systems with little or no modifications.
Now that we have ripped out the stock guts out of our Linksys WRT54G and replaced them with a miniature, but mighty, Linux operating system, it's time to configure it to do some actual work. (Part 1 and part 2 cover installation and setting up secure administration of your chopped, dropped little blue box.)
Did you know Konqueror has a handy little program to create photo galleries in a few quick steps? Here's how to use it.
In this introductory article, Jon Watson provides an easy guide to installing the new Open Office source on non-rpm Linux systems. The emphasis is on the use of alien to help convert rpm packages for quick installation to the latest Debian releases.
Sudo is a handy little tool that is of value to both system administrators and common folks like us. What does it do? It allows you to temporarily assume the permissions of another user, up to and including root.
Last week, I wrote a small introduction to Gaim, a great chat client written for GTK. The functionality of Gaim has gotten quite advanced, which has made it one of the leading-edge open-source chat clients currently available.
