Rebuilding the OpenBSD kernel

Post date: April 24, 2005, 20:04 Category: System Views: 4065 Comments
Tutorial quote: Users who want their OpenBSD machine to perform specific functions or need additional device drivers might want to customize their kernel. In other OS's, like some types of Linux, it is very popular to rebuild the kernel because the default is so bloated. For most users, the default OpenBSD kernel is sufficient; however, you should still apply kernel patches, which will require rebuilding and installing a fresh kernel.

Write your own kernel module and insert it into running kernel

Post date: January 12, 2009, 08:01 Category: Programming Views: 4463 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.

screen: Keep Your Processes Running Despite A Dropped Connection

Post date: December 12, 2006, 20:12 Category: System Views: 2732 Comments
Tutorial quote: I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labour. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task. This short tutorial shows how to use screen for just this purpose.

CD burning with a 2.6 kernel (IDE)

Post date: January 18, 2006, 00:01 Category: Multimedia Views: 3039 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.

Tutorial quote: The following list shows tunable kernel parameters you can use to secure your Linux server against attacks.

For each tunable kernel parameters you need to be add it to the /etc/sysctl.conf configuration file to make the change permanent after reboots

Installing Xen 3.0 upon Debian Unstable, with a custom Kernel

Post date: December 29, 2005, 07:12 Category: System Views: 3483 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.

Choosing an I/O Scheduler for Red Hat Enterprise Linux 4

Post date: July 18, 2005, 22:07 Category: Benchmarks Views: 7407 Comments
Tutorial quote: The Linux kernel, the core of the operating system, is responsible for controlling disk access by using kernel I/O scheduling. Red Hat Enterprise Linux 3 with a 2.4 kernel base uses a single, robust, general purpose I/O elevator. The 2.4 I/O scheduler has a reasonable number of tuning options by controlling the amount of time a request remains in an I/O queue before being serviced using the elvtune command. While Red Hat Enterprise Linux 3 offers most workloads excellent performance, it does not always provide the best I/O characteristics for the wide range of applications in use by Linux users these days. The I/O schedulers provided in Red Hat Enterprise Linux 4, embedded in the 2.6 kernel, have advanced the I/O capabilities of Linux significantly. With Red Hat Enterprise Linux 4, applications can now optimize the kernel I/O at boot time, by selecting one of four different I/O schedulers.

Installing Xen 3.3 With Kernel 2.6.27 On Ubuntu 8.10 (x86_64)

Post date: February 24, 2009, 12:02 Category: Installing Views: 3081 Comments
Tutorial quote: This tutorial shows how you can install Xen 3.3 on an Ubuntu 8.10 host (dom0). Xen 3.3 is available from the Ubuntu 8.10 repositories, but the Ubuntu 8.10 kernels (2.6.27-x) are domU kernels, i.e., they work for Xen guests (domU), but not for the host (dom0). Therefore we need to build our own dom0 kernel. This guide explains how to do this with a 2.6.27 kernel.
