Setting the Clock on Linux

Post date: April 12, 2005, 17:04 Category: System Views: 2621 Comments
Tutorial quote: There are 3 protocols dealing with time: NTP (port 123), Time (port 37), and Daytime (port 13). If you're connecting to the Internet periodically, then synchronizing your clock when you dial up or from crontab is good enough. This applies also to most Linux machines at home or at work, even if they are connected all the time. Here is a short tutorial on how to set your clock using these 3 protocols.

Linux 2.6: Compiling and Installing

Post date: April 15, 2005, 22:04 Category: System Views: 3180 Comments
Tutorial quote: We'll look at the process of compiling and installing a new kernel safely, without overwriting the existing kernel.

You can install as many kernels as you like on a Linux system, and select the one you want to run at boot time. This makes it easy to test different kernels, and different kernel configurations, with particular sets of hardware or applications. The wise network admin always tests new kernels before running them on production machines.

shred - Securely delete files in Linux

Post date: January 24, 2010, 06:01 Category: Security Views: 4709 Comments
Tutorial quote: In case you want to delete some confidential data from your computer just to make sure that it is no longer accessible to anyone, then do not delete the file using the regular rm command because there will still remain a chance that someone might use a software to recover your deleted data before the specific storage area is overwritten by new data. The proper way to permanently dispose of such data in Linux is the shred command.

Xen Virtualization and Linux Clustering, Part 1

Post date: January 21, 2006, 06:01 Category: System Views: 4040 Comments
Tutorial quote: Have you heard about Xen virtualization and want to get some hands-on experience? Do you want to experiment with Linux clustering but only have a single computer to devote to the cause? If you answered yes to either of these questions, keep reading.

In this article, I briefly introduce the concepts of Xen virtualization and Linux clustering. From there, I show you how to set up multiple operating systems on a single computer using Xen and how to configure them for use with clustering. I should point out that a cluster implemented in this manner does not provide the computational power of multiple physical computers. It does, however, offer a way to prototype a cluster as well as provide a cost-effective development environment for cluster-based software. Even if you're not interested in clustering, this article gives you hands-on experience using Xen virtualization.

Benchmarking BSD and Linux

Post date: June 18, 2005, 22:06 Category: Benchmarks Views: 4117 Comments
Tutorial quote: These benchmarks are the result of my scalable network programming research. My interest in this area is to see how scalable and fast network applications can be on standard PC hardware.

I have done most of my research on Linux 2.4, 2.5 and 2.6 kernels using a home-grown distribution I affectionately call "Leanux". I have experimented with several APIs and methods to try and get the most scalability and performance out of a web server. The ultimate goal, however, is to demonstrate scalability by surviving a Slashdotting.

Changing Desktop Appearance On Linux Mint 11 (Advanced)

Post date: October 13, 2011, 07:10 Category: Desktop Views: 4603 Comments
Tutorial quote: This tutorial is supposed to show you how to change the GNOME desktop appearance on Linux Mint 11 further than the standard options of the Appearance section in the Control Center allow. I am going to use several different applications for this cause. This is the standard desktop that comes with Mint, so if you have not changed anything about that all steps should work fine for you. Be aware that the use of the nVidia proprietary drivers may not be unrisky!

A Guide to Virtualization on Mandriva Linux 2007 Spring

Post date: May 14, 2007, 23:05 Category: System Views: 3816 Comments
Tutorial quote: Have you ever wished you had another computer handy? Maybe you want to try a new operating system out. Maybe you want to test something experimental without potentially breaking your own system. Maybe you need to run some software that only runs in a different operating system. Mandriva Linux 2007 Spring comes with a range of virtualization options that can help.
