How To Install Qmailtoaster (CentOS 5.3)

Post date: June 19, 2009, 10:06 Category: Installing Views: 8283 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.

Serving CGI Scripts With Nginx On Debian Squeeze/Ubuntu 11.04

Post date: October 3, 2011, 06:10 Category: Miscellaneous Views: 5612 Comments
Tutorial quote: This tutorial shows how you can serve CGI scripts (Perl scripts) with nginx on Debian Squeeze/Ubuntu 11.04. While nginx itself does not serve CGI, there are several ways to work around this. I will outline three solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second and third solution are very similar - both use a CGI wrapper to serve CGI scripts.

Preventing MySQL Injection Attacks With GreenSQL On Debian Etch

Post date: October 28, 2008, 12:10 Category: Security Views: 4341 Comments
Tutorial quote: GreenSQL (or greensql-fw) is a firewall for MySQL databases that filters SQL injection attacks. It works as a reverse proxy, i.e., it takes the SQL queries, checks them, passes them on to the MySQL database and delivers back the result from the MySQL database. It comes with a web interface (called greensql-console) so that you can manage GreenSQL through a web browser. This guide shows how you can install GreenSQL and its web interface on a Debian Etch server.

Build your own gateway firewall

Post date: April 11, 2006, 21:04 Category: Miscellaneous Views: 5677 Comments
Tutorial quote: Learn how to build your own gateway firewall using FreeBSD and old PC parts. The firewall will consist of the PF firewall, Snort IDS, various IPS applications, Squid proxy, and some intuitive web interfaces for auditing. The cost of this project should be between free and $200 depending on your resourcefulness. I built mine for free using spare parts that were stockpiled in personal storage and parts that the USMC was throwing away, but you can build one from used and/or new parts for dirt cheap.

Postfix Monitoring With Mailgraph And pflogsumm

Post date: July 16, 2006, 16:07 Category: Miscellaneous Views: 4440 Comments
Tutorial quote: This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix. These graphs can be accessed with a browser, whereas pflogsumm ("Postfix Log Entry Summarizer") can be used to send reports of Postfix activity per email.

Installing and securing Squid

Post date: March 13, 2006, 15:03 Category: Software Views: 5559 Comments
Tutorial quote: Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests. Squid supports SSL, extensive access controls, and full request logging. By using the lightweight Internet Cache Protocol, Squid caches can be arranged in a hierarchy or mesh for additional bandwidth savings.

After the installation and base configuration of squid we will add another layer of security by chrooting it.
