Automatic Cleaning Of Trash And/Or Junk Folders With ISPConfig (With Roundcube + Tmpreaper (Tmpwatch))

Most (web)mail clients (can) automatically create these. A lot of people don't clean there maildirectories causing Junk and Trash folders to grow massively in size and with ISPConfig (not yet) being able to set good maildirectory size limits the alternative is to have these folders cleaned after several days.

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.

How To Set Up WebDAV With Lighttpd On Mandriva 2008.1

This guide explains how to set up WebDAV with lighttpd on a Mandriva 2008.1 server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the lighttpd server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

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.

How To Block Porn Pictures And Images With SafeSquid Proxy Server

Administrators can use various methods to block access to websites that are pornographic in nature, like URL Filter, URL Blacklist, Keyword Filter, etc. But many porn sites allow users to register their email IDs on their website and deliver the latest images and pictures to their personal emails. So if a user is allowed access to his personal mail, he can enjoy himself without having to access any porn site. Such images are also regularly displayed as ads and banners on other web pages, that might not be pornographic in nature. Pornographic Image Filter can analyze an image in real-time, and identify the ones that are pornographic in nature. It analyzes the graphical content like skin tone, contour, etc. to identify a pornographic image. It is a commercially distributed add-on plug-in and can be used with SafeSquid to block pornographic images. Although it is about 85%-90% accurate, it acts as a good deterrent.

Install Ubuntu With Software RAID 10

The Ubuntu Live CD installer doesn't support software RAID, and the server and alternate CDs only allow you to do RAID levels 0, 1, and 5. Raid 10 is the fastest RAID level that also has good redundancy too. So I was disappointed that Ubuntu didn't have it as a option for my new file server. I didn't want shell out lots of money for a RAID controller, especially since benchmarks show little performance benefit using a Hardware controller configured for RAID 10 in a file server.

Creating Advanced MySQL-Based Virtual Hosts On Lighttpd (Debian Etch)

This guide explains how you can create advanced virtual hosts on a lighttpd web server on Debian Etch that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a database), this method allows to store individual configuration directives for each vhost in the MySQL database.

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

This article explains how you can install and configure apache2-mpm-itk on a Debian Etch server. apache2-mpm-itk is an MPM (Multi-Processing Module) for the Apache 2 web server. mpm-itk allows you to run each of your vhost 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. mpm-itk works with mod_php because mpm-itk is based on the traditional prefork MPM, which means it's non-threaded. This means you don't need to use suExec or suPHP anymore to run a website's PHP scripts as a separate user.
