Normally the network interface cards are configured during the installation of Linux. However, sometimes certain circumstances require you to change the addressing scheme of your system. This article will take you step by step through the process of configuring your system to use DHCP for obtaining its IP addressing information. Ubuntu has some very nice GUI tools to allow you to change your settings with the click of the mouse but this article will focus on how to make your changes from a command line in the event that you don’t have the GUI installed. Also, this tutorial is Ubuntu/Debian centric but the principles can be applied to many other Linux distributions, especially any that are based on Debian.

The company I work for uses Citrix to deliver Terminal Services desktops to users through-out the organization and remotely. One of the applications used relies heavily on allowing the “Print Screen” button to generate a print job. Within the walls of the organization this work quite well. We have Wyse Winterm 1200LE’s that pass the “Print Screen” key press through to the Citrix servers quite effectively. However, when using the Citrix Web Interface remotely the “Print Screen” function is captured by the host operating system and not passed through the Citrix ICA web client to the server.

PuTTY is an invaluable tool that I use nearly every day at work. The two main functions I use if for is telnetting into Cisco devices and secure shell access to remote Linux servers. It allows for the storing of host session information for easy recall. Another advantage is that it is a single executable file which makes it extremely portable. Just toss it on a memory stick and carry it with you in your pocket. The best part is that it’s free!

Secure Shell (SSH) is a protocol that uses encryption to create a secure channel from a local computer to a remote computer. It is primarily used to execute commands on a remote host via a terminal session. In addition, it allows for tunneling and file transfer. It’s a handy little tool that allows remote access with a fair sense of security. It’s very simple to install on Ubuntu with the Advanced Packaging Tool (APT).

If you haven’t already heard, Because of The Energy Policy Act of 2005 Daylight Savings Time in the USA will start 3 weeks earlier at 2am on the second Sunday in March and end one week later at 2am on the first Sunday in November. It’s important that you check your current settings to make sure you don’t have any issues or get your time out of sync. Even if you have your time updated via NTP, you aren’t covered. NTP operates by setting your computer time to UTC or Universal Standard Time. Your computer then calculates the correct local time according to your time zone settings.

Enabling the root user password is convenient when you first setup a server. Often there are many procedures that require root access. If you have the root account enabled you will save yourself the time and keystrokes that it takes to emulate the root user with the “sudo” command. You also have the option of disabling the root user when you are done.

This tutorial is going to highlight the installation of a Linux, Apache, MySQL and PHP (LAMP) server. A LAMP server will be the basis of a few other projects I intend to write tutorials about so what better place to start? At the end of this tutorial we will have a server running Ubuntu 6.06 Linux capable of hosting a website. Pretty basic, I know, but it will be invaluable in the future.

Most people are accustomed to having a clock in the notification area (also known as the system tray) on their windows desktop. In the Microsoft Terminal Services world that isn’t the default behavior. The clock is hidden by default for remote sessions to save network traffic caused by screen refreshes occuring at minute intervals. The problem I’ve found is that when users are used to having something as simple as a clock in their notification area, they aren’t very understanding when it is no longer there.
