How To Secure Your Ubuntu 10.10 Desktop With LinOTP 2

How To Secure Your Ubuntu 10.10 Desktop With LinOTP 2

This howto will guide you to set up a LinOTP standalone one time password authentication backend on your Linux machine. This enables you to add two factor authentication with one time passwords to your desktop login. LinOTP is a modular OTP (one time password) solution, that supports many different OTP tokens. LinOTP is written in python, based on pylons and apache. It comes as open source licensed under the AGPLv3. Additional functionalities, maintenance and support can be licensed in an Enterprise Edition. This howto should run on Ubuntu 10.10 and Debian Squeeze.

Installing Cherokee With PHP5 And MySQL Support On Debian Squeeze

Installing Cherokee With PHP5 And MySQL Support On Debian Squeeze

Cherokee is a very fast, flexible and easy to configure Web Server. It supports the widespread technologies nowadays: FastCGI, SCGI, PHP, CGI, TLS and SSL encrypted connections, virtual hosts, authentication, on the fly encoding, load balancing, Apache compatible log files, and much more. This tutorial shows how you can install Cherokee on a Debian Squeeze server with PHP5 support (through FastCGI) and MySQL support.

Tiny Web Proxy And Content Filtering Appliance (Version 1.2) With Debian Squeeze

Tiny Web Proxy And Content Filtering Appliance (Version 1.2) With Debian Squeeze

This small HOWTO will show you how to set up a small virtual machine to speed up and secure your home / small enterprise web surfing network using Debian 6, Squid 3.1 and QuintoLabs Content Security 1.2 applications deployed in a VMWare Virtual Player running on Windows 7 x64 as a host operating system. This howto is targeted at novice users and may sometimes seem too thorough for more advanced gurus.

amon.so: Hijacking System Calls For Hardening PHP - Debian Lenny And Squeeze

amon.so: Hijacking System Calls For Hardening PHP - Debian Lenny And Squeeze

amon.so is a library that integrates with the PHP interpreter and intercepts and manipulates the system calls provided by libc6. It replace the execve() syscall with a custom function which does extra sanity checking in order to prevent that an attacker could execute arbitrary code on the system exploiting a vulnerability in a web-based application (such as a bugged cms). It's open-source software released under the terms of the GPL license and compatible with PHP running as a CGI process or Apache's DSO module.

How To Save Traffic With Lighttpd's mod_compress (Debian Squeeze)

How To Save Traffic With Lighttpd's mod_compress (Debian Squeeze)

In this tutorial I will describe how to configure mod_compress on a Lighttpd web server (on Debian Squeeze). mod_compress allows Lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_compress, you can compress HTML, CSS, Javascript, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.

Paravirtualization With Xen 4.0 On Debian Squeeze (AMD64)

Paravirtualization With Xen 4.0 On Debian Squeeze (AMD64)

This tutorial provides step-by-step instructions on how to install Xen 4.0 on a Debian Squeeze (6.0) system (AMD64) and create paravirtualized guests. 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.

Enabling Compiz Fusion On A Debian Squeeze Desktop (Nvidia GeForce 8200)

Enabling Compiz Fusion On A Debian Squeeze Desktop (Nvidia GeForce 8200)

This tutorial shows how you can enable Compiz Fusion on a Debian Squeeze desktop (the system must have a 3D-capable graphics card - I'm using an Nvidia GeForce 8200 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.

Set Up OpenVPN Server With Authentication Against OpenLDAP On Debian 6.0 (Squeeze)

Set Up OpenVPN Server With Authentication Against OpenLDAP On Debian 6.0 (Squeeze)

OpenVPN, or Open Virtual Private Network, is a tool for creating networking "tunnels" between and among groups of computers that are not on the same local network. This is useful if you have services on a local network and need to access them remotely but don't want these services to be publicly accessible. By integrating with OpenSSL, OpenVPN can encrypt all VPN traffic to provide a secure connection between machines.

Virtual Users With Postfix, Dovecot, MySQL, RoundCube, iRedAdmin On Debian 6.0 (Squeeze)

Virtual Users With Postfix, Dovecot, MySQL, RoundCube, iRedAdmin On Debian 6 (Squeeze)

This document describes how to install a Postfix and Dovecot mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. If you prefer to install such a mail server step by step, you can refer to the ISPmail tutorials at workaround.org. Also the Big Picture would help you to easily understand the mail server structure. I believe you at least need one day to have a working mail server that way. If you use the iRedMail script, you only need one minute to get the mail server up and running, and you will have more features (compared to the ISPmail tutorials).

Make Browsers Cache Static Files With mod_expire On Lighttpd (Debian Squeeze)

Make Browsers Cache Static Files With mod_expire On Lighttpd (Debian Squeeze)

This tutorial explains how you can configure Lighttpd to set the Expires HTTP header and the max-age directive of the Cache-Control HTTP header of static files (such as images, CSS and Javascript files) to a date in the future so that these files will be cached by your visitors' browsers. This saves bandwidth and makes your web site appear faster (if a user visits your site for a second time, static files will be fetched from the browser cache). This tutorial was written for Debian Squeeze.
