How To Compile A Kernel - The Ubuntu Way

Post date: November 8, 2006, 18:11 Category: System Views: 4536 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 Ubuntu 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.

Managing Xen With Xen-Tools, Xen-Shell, And Argo

Post date: November 5, 2006, 21:11 Category: System Views: 4120 Comments
Tutorial quote: This guide describes how to install and use xen-tools, xen-shell, and Argo on a Debian system. All three packages provide useful tools for the administration of virtual Xen machines. Xen-tools is a collection of Perl scripts that allow you to easily create, update, and delete Xen guest domains. The xen-shell provides a command-line interface to owners of Xen domains so that they can manage their Xen domains without the help of the server administrator. And with Argo, you can control Xen domains through a web interface or through a menu on the command line.

Recover a dead hard drive using dd

Post date: October 23, 2006, 03:10 Category: System Views: 15151 Comments
Tutorial quote: The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.

Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.

Rescuing systems using the Debian snapshot server

Post date: September 18, 2006, 14:09 Category: System Views: 5075 Comments
Tutorial quote: One of the unofficial Debian project resources which doesn't get the attention it deserves is the Debian Snapshot site. The site contains a mirror of old Debian packages, which can be very useful for system recovery.

In most normal cases you won't ever need to use it, unless you're wanting to compare two different package versions to see changes, or do other non-standard things. However when you do need to use it you'll learn what a big lifesaver it is!

The biggest use for the site, for me, has been for recovering from broken package updates. Whilst these are rare in the Debian Stable and Testing releases they can be an issue when running Debian unstable.

Tutorial quote: A common task for System Administrators is to monitor and care for a server. That's fairly easy to do at a moment's notice, but how to keep a record of this information over time? One way to monitor your server is to use the Sysstat package.

Sysstat is actually a collection of utilities designed to collect information about the performance of a linux installation, and record them over time.

It's fairly easy to install too, since it is included as a package on many distributions.
