Linux is great, but sometimes a guy's gotta play games. Here's how to set up a quicker Dual-Boot to get you back into windows.
Bottom line #1: Don't make a System Update blindly.
Bottom line #2: Don't make non-security updates "just because you can".
If you've inheritted a bunch of machines, or have only a single generic server in front of you, then you might be curious to learn what hardware you have. Thankfully it is very simple to discover information about your system, even remotely.
LDAP and Sendmail offer sys admins considerable advantages for dynamic mail routing and centralized alias management.
Xen 3.0 is the latest release of the popular virtualisation platform. It allows you to install "virtual servers" upon your base operating system, allowing you to create and run several instances of GNU/Linux upon one host. Here we'll take a simple overview at using Xen to install virtual servers.
If you want support for proprietary file formats like mp3 and quicktime support as well as install softwares not included on the CD, then you have to do some work. Here I share my experiences in putting the Ubuntu house in order on my machine.
Webmasters looking to provide search capabilities for their site would do well to try out PhpDig, a Web spider and search engine written in PHP with a MySQL backend. PhpDig happens to suit the needs of my site. Here's how I got it working.
This is a detailed description about the steps to set up a Ubuntu based server (Ubuntu 5.10 - Breezy Badger) to act as file- and print server for Windows (tm) workstations in small workgroups.
My company has a Linux cluster with a terabyte of attached storage. Over time we noticed the head node was becoming more overloaded. Inspection of the system showed that users were starting dozens of copies of the du utility to determine disk space usage. This was a natural thing for them to do, because they had a need to know how much disk space was available.
One of the largest efforts involved with software engineering is testing the software to make sure that it works as designed. Testing can require several different types of system configurations and could require multiple instances of Linux. One way to create this type of environment is to use a virtual machine.
The question of setting time comes up frequently. Setting the timezone and the system clock can be confusing, particularly if the machine is dual boot.
The best Unix text editor is the one you know, and, today, many people do know Emacs. Scuttlebutt has it that even Bill Joy — the creator of vi — uses Emacs. With Emacs users in mind, Tom Benton presents some useful XEmacs customizations.
Hackers don many disguises in order to sneak past IT security guards. The rootkit, one of the most effective disguises, not only masks the intruder, but covers his trail.
I keep getting inquiries about creating a system with mulitple video monitors, keyboards, and mice for simultaneous use by multiple users under X11R6.9. Here is a mini-Howto document that I've put together.
We've covered SSH before in CLI Magic, but this week let's look at some additional SSH features that new users might not be aware of. For the purpose of this article, we'll be looking specifically at OpenSSH, but many of these features apply to other SSH variants as well.
