How To Compile A Kernel - The Debian (Sarge) Way

Post date: December 21, 2006, 22:12 Category: System Views: 3293 Comments
Tutorial quote: Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on Debian Sarge systems. It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there.

Write your own kernel module and insert it into running kernel

Post date: January 12, 2009, 08:01 Category: Programming Views: 4551 Comments
Tutorial quote: So, you want to write a kernel module. You know C, you've written a few normal programs to run as processes, and now you want to get to where the real action is, to where a single wild pointer can wipe out your file system and a core dump means a reboot.

kernel Modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. For example, one type of module is the device driver, which allows the kernel to access hardware connected to the system.

Failover Firewalls with OpenBSD and CARP

Post date: April 28, 2005, 02:04 Category: Network Views: 7692 Comments
Tutorial quote: Firewalls are a required component in commercial and residential computer networks. For many installations, the firewall is a single point of failure between client systems and external resources. It can also become a liability when hardware or applications fail, leaving potential customers unable to reach your servers. A properly designed and executed failover configuration for your primary firewall will address many of these concerns. This article introduces a proven method for installing redundant stateful firewalls using native OpenBSD features.

Comparing MySQL performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3451 Comments
Tutorial quote: With the introduction of the 2.6 Linux kernel, FreeBSD-5-STABLE, Solaris 10, and now NetBSD 2.0, you might be wondering which of them offers superior database performance. In my previous article, I discussed the tools I chose to test these venerable operating systems and the methodology by which they were tested. The result is this MySQL performance comparison between OpenBSD 3.6; NetBSD 2.0; FreeBSD 5.3 and 4.10; Solaris Express (build 69); and Linux 2.4 and 2.6 (Gentoo-based). Read on for the results.

CD burning with a 2.6 kernel (IDE)

Post date: January 18, 2006, 00:01 Category: Multimedia Views: 3105 Comments
Tutorial quote: Under the 2.4 series kernel - to be able to use an IDE CD burner we were forced to use SCSI emulation (via the kernel module ide-scsi). Under the 2.6 series kernel - this is deprecated - we now use ide-cd.

Firewalling with OpenBSD's PF packet filter

Post date: November 27, 2006, 02:11 Category: Network Views: 7479 Comments
Tutorial quote: The tutorial is about firewalls and related functions, with examples from real life with the OpenBSD project's PF (Packet Filter). PF offers firewalling, NAT, traffic control and bandwidth management in a single, flexible and sysadmin friendly system. Targeted at the seasoned or aspiring network administrator, this half day tutorial manuscript will give you some ideas about how to control your network traffic the way you want - keeping some things outside your network, directing traffic to specified hosts or services, and of course, giving spammers a hard time.

Installing Xen 3.0 upon Debian Unstable, with a custom Kernel

Post date: December 29, 2005, 07:12 Category: System Views: 3551 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.
