Working with SUSE Linux Enterprise Server 9

Post date: June 22, 2005, 09:06 Category: System Views: 3486 Comments
Tutorial quote: Working with SUSE Linux Enterprise Server (SLES) requires an understanding of the login process, including local account files, system accounts, and managing identities.

Using a console shell or the graphical environment are two possible methods of working on a SLES machine.

Finding your way around a SLES installation requires an in-depth knowledge of the filesystem layout. Essential filesystem components are documented and explained in this chapter. Basic filesystem permissions are also described.

Step By Step Ubuntu 9.04 (Jaunty) LAMP Server Setup

Post date: May 12, 2009, 07:05 Category: Benchmarks Views: 6919 Comments
Tutorial quote: In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux,Apache, MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications.

Installing Xen 3.0 upon Debian Unstable, with a custom Kernel

Post date: December 29, 2005, 07:12 Category: System Views: 3523 Comments
Tutorial quote: Recently we demonstrated the process of installing a binary release of Xen 3.0 on Sarge, since the packages on Debian Unstable are not yet available for Xen 3.0 we're now going to look at installing it via the packages provided by Ralph Passgang. This also includes building a custom Xen kernel from source.

The advantage to building the Xen kernel from source is that you can add, or remove, drivers - so the kernel is utterly customised for your system.

Using Impress-ive Charts In OpenOffice.org

Post date: April 14, 2005, 13:04 Category: Software Views: 2352 Comments
Tutorial quote: Anybody that does presentations will someday need to use a chart. A manager needs charts to show production numbers and profits. A scientist or trainer needs charts to show facts, figures and results. A sales seminar leader needs charts to explain sales figures. So, what's involved in getting these nifty things into your OpenOffice.org-based slide show?

The process of integrating charts into your Impress slide show is fairly straightforward, although it does involve a few steps and two different components of OpenOffice.org.

OpenVZ On Debian Etch For Webservers

Post date: December 26, 2006, 21:12 Category: System Views: 3287 Comments
Tutorial quote: Virtualization is a good practice for servers, since it makes things more secure, scalable, replacable, and replicable, all this at the cost of little added complexity. This guide was written during an install of a Supermicro machine with two dual-core opterons (64-bit), two identical disks (for RAID) and a load of memory. Why OpenVZ and not XEN or the recent KVM kernel module? Well, XEN is not very stable for 64-bit architectures (yet), and it comes with quite a bit of overhead (every VM runs its own kernel) due to its complexity. KVM is very simple but restricts you to run a kernel as one process, so the VM cannot benefit from multi core systems.

Ubuntu 8.10 (Intrepid Ibex) LAMP Server Setup

Post date: November 5, 2008, 07:11 Category: System Views: 21272 Comments
Tutorial quote: In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache,MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.Instead, you get increased security, reduced time-to-install, and reduced risk of misconfiguration, all of which results in a lower cost of ownership.

The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a
process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications.

Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

Post date: October 10, 2007, 10:10 Category: Installing Views: 4192 Comments
Tutorial quote: Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.

Fbsplash on gentoo

Post date: April 12, 2005, 05:04 Category: Multimedia Views: 3579 Comments
Tutorial quote: Gensplash is a project started by Spock whose aim is to create a set of tools which could enrich the Gentoo boot process by displaying messages, animations, progress bars, etc. An explanation of the various things named *splash (bootsplash, gensplash, fbsplash, and splashutils) and how they relate to each other, can be found at Spock's Gensplash site.

Fbsplash is part of the gensplash project. According to fbsplash's documentation, "the framebuffer splash is a kernel feature that allows displaying a background picture on selected consoles and switching the first console to the so-called silent mode, while booting/rebooting/shutting down the system." The fbsplash device is accessed through the /dev/fbsplash device node. For fbsplash to work, a frame buffer device is required.

Hardening Linux: a 10 step approach to a secure server

Post date: June 22, 2005, 10:06 Category: Security Views: 3527 Comments
Tutorial quote: The Internet has become a far more dangerous place than it was 20 years ago. Nowadays, Operating System and application security is an integral part of a server configuration and, while firewalls are very important, they are not the panacea.

This list of steps is intended as a guideline with a practical approach. We’ll try to provide a complete picture without getting into unnecesary details. This list won’t replace a good book on secure systems administration, but it will be useful as a quick guide.

Before we get started it’s worth to mention that security is not a status: it’s just a process. The correct initial setup of the server only provides a good start and helps you get half the way through. But you actually need to walk the other half of the road, by providing proper security vigilance, monitoring and updating.
