Post date: June 17, 2008, 09:06 Category: Installing Views: 3918 Comments
Tutorial quote: This tutorial shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

Encrypt-Decrypt files using mcrypt on OpenSuse

Post date: January 27, 2009, 07:01 Category: Security Views: 4098 Comments
Tutorial quote: MCrypt is a replacement for the old crypt() package and crypt(1) command, with extensions. It allows developers to use a wide range of encryption functions, without making drastic changes to their code. It allows users to encrypt files or data streams without having to be cryptographers. Above all, it allows you to have some really neat code on your machine. :)

The companion to MCrypt is Libmcrypt, which contains the actual encryption functions themselves, and provides a standardized mechanism for accessing them.

Webmin installation and configuration on OpenSuSe

Post date: November 17, 2008, 11:11 Category: Installing Views: 4932 Comments
Tutorial quote: Webmin, developed by Jamie Cameron, acts as a comprehensive interface to the underlying applications on servers, including support for configuring applications like ftp, ssh, mail, Web, databases and more. Differing from other control panels, the core Webmin interface is intended for system administrators with root access to their servers, and includes a user-based package to enable your users (or clients) to access their own domains, email, and more, within a limited scope. Webmin supports running under SSL.

Using mixmaster to send anonymous email

Post date: January 26, 2007, 07:01 Category: Network Views: 32366 Comments
Tutorial quote: This is a document that explains how to install mixmaster and how to use it to send email, in an anonymous and secure fashion.

Mixmaster is described by the debian package system as:

Mixmaster is the reference implementation of the type II remailer protocol which is also called Mixmaster.

An anonymous remailer is a computer service that privatizes your email. A remailer allows you to send electronic mail to a Usenet news group or to a person without the recipient knowing your name or your email address. Anonymous remailers provide protection against traffic analysis.

Configuring Dynamic DNS & DHCP on Debian Stable

Post date: February 3, 2006, 01:02 Category: Network Views: 4253 Comments
Tutorial quote: For the average home computer user there is no need to install a complex package such as the Internet Software Consortium's BIND DNS or DHCP server, since there are far simpler lower resource tools to use, for example dnsmasq. For those who you wish to learn how to use ISC's BIND and DHCP, for example as a learning exercise, this is how I got it all to work in Debian Sarge, the current stable version of Debian GNU/Linux.

This short article was prompted by my question on the Debian-Administration forum site, where I was able to get some answers to the issues I faced and I did promise to post a solution if I got one.

A Short Introduction To Apt-Pinning

Post date: March 24, 2009, 12:03 Category: Miscellaneous Views: 3966 Comments
Tutorial quote: This article is a short overview of how to use apt-pinning on Debian and Debian-based distributions (like Ubuntu). Apt-Pinning allows you to use multiple releases (e.g. stable, testing, and unstable) on your system and to specify when to install a package from which release. That way you can run a system based mostly on the stable release, but also install some newer packages from testing or unstable (or third-party repositories).

A web server in a shell script

Post date: March 14, 2006, 08:03 Category: Programming Views: 17224 Comments
Tutorial quote: Suppose you want to experiment a little with web pages and CGI's, but you don't want the hassle of installing the full Apache package. This quick and dirty shell script could just be what you need.

Put simply, a web server is an application that sends local text files over the network to the clients that request them. If you let another program (for example inetd) deal with the network part, the web server could be reduced to a mere cat "$filename" to stdout. Of course, the difficult part would be to extract that filename out of the HTTP request string: nothing that a Bash script cannot easily do!

How To Install Qmailtoaster (CentOS 5.3)

Post date: June 19, 2009, 10:06 Category: Installing Views: 8328 Comments
Tutorial quote: Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.
