Installing Oracle VM VirtualBox on Ubuntu

Post date: October 10, 2010, 05:10 Category: Software Views: 4503 Comments
Tutorial quote: What does that mean? For one thing, VirtualBox installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac, Linux or Solaris operating systems. Secondly, VirtualBox extends the capabilities of your existing computer so that VirtualBox can run multiple operating systems (inside multiple virtual machines) at the same time. So, for example, you can run Windows and Linux on your Mac, run Windows Server 2008 on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications. You can install and run as many virtual machines as you like -- the only practical limits are disk space and memory.

Setting up a local web server in Debian Linux

Post date: January 21, 2006, 06:01 Category: Network Views: 2998 Comments
Tutorial quote: Any web developer, designer, or webmaster can benefit from having a local web server. Even if that developer has no interest in securing and maintaining the server his or her websites live on, a local server can act as a convenient mirror for testing updates, trying new designs, and other general sand-boxing activities.

Web developers whose hosts utilize the popular LAMP platform (Linux + Apache + MySQL + PHP) are frequently hit with a dilemma. Since understanding Linux is not a prerequisite for website administrators, many of them lack the knowledge necessary for setting up a LAMP server from scratch (or at least they may think so). But thanks to the improved package management on Linux distributions like Debian, installing a functional web server is not nearly the chore it was just a couple years ago.

Mini-Howto for User Mode Linux

Post date: April 12, 2005, 17:04 Category: System Views: 2572 Comments
Tutorial quote: UML ("User Mode Linux") allows you to run multiple Linux servers on one physical machine. This can be handy for many different purposes. For example, you might want to give different people root rights, but prevent them from interfering with one another. Or, you might want to have several identically configured servers, one for production, one for development, and one for testing, but without investing in multiple physical machines.

Once you have prepared your machine for running UML instances as described in the following section, adding new instances will take less than five minutes. The preparation, however, might take a bit longer.

Configure Multiple Network Profiles on Linux

Post date: April 13, 2005, 02:04 Category: Network Views: 2848 Comments
Tutorial quote: Mobile Linux users face some interesting (OK, vexing) challenges when they want to plug into different networks. Any Linux system will easily support all manner of networking profiles--dialup, ISDN, Ethernet, wireless--the tricky bit is configuration. Manually re-configuring a PC for every connection is low on most users' lists of "fun things to do." You can be an ace scripting guru and fiddle up something yourself, or you can find a nice ready-made utility to do the work for you. Unfortunately, I have not found a universal utility to do this. However, there are a lot of utilities specific to various distributions, and an assortment of other utilities.
