Spam Blocking And Web Filtering With The Untangle 5.3 Network Gateway

Spam Blocking And Web Filtering With The Untangle 5.3 Network Gateway

Untangle bundles common open-source applications for blocking spam, spyware, viruses, adware and unwanted content on the network in one single Linux distribution. It can be integrated into existing networks either as a router or as a transparent bridge (directly behind the router, but before the switch that connects the client PCs with the router). The best thing about Untangle is that you don't have to reconfigure the client PCs - Untangle works out of the box.

Preventing Brute Force Attacks With Fail2ban On Mandriva 2008.1

In this article I will show how to install and configure fail2ban on a Mandriva 2008.1 system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch

This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.
