Giving your Xen instances a working X setup

Post date: January 3, 2006, 04:01 Category: Software Views: 3171 Comments
Tutorial quote: Xen, the virtualisation system, is a great tool for running fresh copies of an operating system. However it doesn't allow you to run X11 programs. Here we can fix that with the help of VNC.

The PartImage Handbook

Post date: May 21, 2005, 15:05 Category: Software Views: 3078 Comments
Tutorial quote: - Partition Image is a Linux/UNIX partition imaging utility: it saves partitions formatted using the Ext2FS (the linux standard), ReiserFS (a new journaled and powerful file system), JFS IBM journaled file systems from AIX, NTFS (Windows NT File System), FAT16/32 (DOS & Windows file systems), or HPFS (OS/2 file system) file system formats to an image file. Only used blocks are copied. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable media (ZIP for example), or burned on a CD-R ...

- This allows the user to save a full Linux/Windows system, with a single operation. When problems occur (viruses, crash, error, ...), you just have to restore, and after several minutes, all your system is restored (boot, files, ...), and fully working.

- This is very useful when installing the same software on many machines: just install one of them, create an image, and then restore the image on all other machines. After the first one, each subsequent installation can be made automaticaly, and only requires a few minutes.

Write your own kernel module and insert it into running kernel

Post date: January 12, 2009, 08:01 Category: Programming Views: 5414 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.

Setting up a serial console

Post date: February 19, 2007, 19:02 Category: Miscellaneous Views: 4152 Comments
Tutorial quote: This tutorial will show you how to set up a serial console on a Linux system, and connect to it via a null modem cable. This is quite useful if your Linux server is in a headless configuration (no keyboard or monitor), as it allows you to easily get a console on the system if there are any problems with it (especially network problems, when SSH is not available). In the end, the GRUB menu will appear over the serial link, as will the bootup messages (output when booting the system). I am using Debian Etch on the server and Ubuntu Edgy on my client, although this should work on any Linux distribution.

Apache - Serving up the Web

Post date: April 11, 2006, 22:04 Category: Network Views: 8548 Comments
Tutorial quote: The Apache Web Server is installed as part of the OpenBSD base system. This guide will help you configure the web server: (Apache 1.3.12 is released with OpenBSD 2.7 and 1.3.9 with OpenBSD 2.6)

To see how configurable the Apache/OpenBSD combination is we also look at allowing administrators to remotely review the server's status, we setup the system so we allow users on our system to have their own personal web-space. Of course, for the security counscious you probably want to turn some of these things off after you get things up and running.

Restoring a Sun system using JumpStart technology

Post date: April 13, 2005, 05:04 Category: Installing Views: 4652 Comments
Tutorial quote: If a server crash and the file systems are corrupted or totally destroyed, then the only way to recover the data is to restore from backups. If it is only user data that is corrupted, the task is in general simple, but if the system disk fails, then there is a little bit more work involved in order to to recover the system. This article explains how to backup Sun systems using ufsrestore over NFS, and how to use Sun's JumpStart technology to restore Sun servers and workstations over the network.

How To Install VMware Server On Debian 4.0 (Etch)

Post date: April 24, 2007, 20:04 Category: Installing Views: 4106 Comments
Tutorial quote: This tutorial provides step-by-step instructions about how to install the free VMware Server (version 1.0.2) on a Debian Etch system. With VMware Server you can create and run guest operating systems (virtual machines) such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free). In this article we use Debian Etch (4.0) as the host operating system.
