Paravirtualization With Xen On CentOS 5.3 (x86_64)

Post date: May 17, 2009, 13:05 Category: Miscellaneous Views: 4697 Comments
Tutorial quote: This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.3 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

Creating DjVu Documents Linux HOWTO

Post date: July 16, 2006, 16:07 Category: Miscellaneous Views: 3682 Comments
Tutorial quote: This document explains some of the uses of djvulibre implementation of DjVu for creating quality DjVu documents in linux. DjVu format features bitmap document compression and hypertext structure. It is used by numerous web sites all around the world for storing and distributing digital documents including scanned documents and high-resolution pictures. One of the advantages of DjVu files is that they are notably small, often smaller than PDF or JPEG files with the same content. This makes DjVu a helpful tool for digitizing books and journals, especially scientific ones.

Below it is considered the case when a DjVu document is created from a number of separate JPEG files each containing a single page. Here JPEG format is not a limitation, and the examples can cover arbitrary image formats. Conversion from PDF to DjVu is also discussed. Usage of scanner software is not explained: refer to the relevant documentation.

Transparent proxying with squid and pf

Post date: May 17, 2005, 08:05 Category: Network Views: 12038 Comments
Tutorial quote: squid is a caching web proxy, it's set up between web browsers and servers, fetching documents from servers on behalf of browsers. It can accelerate web access by caching frequently requested pages and serving them from its cache. It can also be used to filter pop-up ads and malware or to enforce access control (which clients may request what pages based on different authentication methods).

Traditionally, the proxy is an optional component, and browsers are configured to actively use the proxy. Transparent proxying means forcing all web traffic through the proxy without the cooperation (or knowledge) of the clients. Once all browser connections pass through the proxy, outgoing connections to external hosts can be restricted to the proxy, and direct connections from local clients can be blocked.

The OpenBSD packet filter (pf) can be used to redirect connections based on various criteria, including source and destination addresses and ports. For instance, one can redirect all TCP connections with destination port 80 (HTTP) that arrive through an interface connected to local workstations to a squid proxy running on a different address and port.
