How To Harden PHP5 With Suhosin On Fedora 7

Post date: July 25, 2007, 23:07 Category: Security Views: 3937 Comments
Tutorial quote: This tutorial shows how to harden PHP5 with Suhosin on a Fedora 7 server. From the Suhosin project page: "Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections."

Watching Your Power Consumption With Powertop On Fedora 7

Post date: October 1, 2007, 10:10 Category: Miscellaneous Views: 3545 Comments
Tutorial quote: Powertop is a command-line tool released by Intel that shows you the power consumption of the applications running on your system. It works best on notebooks with Intel mobile processors and can help you find out the programs that put a strain on your notebook battery. It requires kernel 2.6.21 or newer with tickless idle enabled (CONFIG_NO_HZ) (which is currently available for 32-bit kernels only). Fedora 7 comes with a 2.6.21 kernel by default, so we can use Powertop on it.

Virtual Users & Domains With Postfix, Courier, MySQL, SquirrelMail (Fedora 10)

Post date: February 1, 2009, 11:02 Category: Installing Views: 3815 Comments
Tutorial quote: This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Embedding Python In Apache2 With mod_python (Debian/Ubuntu, Fedora/CentOS, Mandriva, OpenSUSE)

Post date: July 22, 2008, 09:07 Category: Installing Views: 3980 Comments
Tutorial quote: This tutorial shows how to install and use mod_python on various distributions (Debian/Ubuntu, Fedora/CentOS, Mandriva, OpenSUSE) with Apache2. mod_python is an Apache module that embeds the Python interpreter within the server. It allows you to write web-based applications in Python that will run many times faster than traditional CGI and will have access to advanced features such as ability to retain database connections and other data between hits and access to Apache internals.

Majordomo Configuration

Post date: April 10, 2006, 18:04 Category: Network Views: 2800 Comments
Tutorial quote: Majordomo is a program which automates the management of Internet mailing lists. Commands are sent to Majordomo via electronic mail to handle all aspects of list maintenance. Once a list is set up, virtually all operations can be performed remotely by email, requiring no intervention upon the postmaster of the list site.

How To Compile A Kernel - The Fedora Way

Post date: November 14, 2006, 20:11 Category: System Views: 5233 Comments
Tutorial quote: Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on Fedora systems. It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there.

Today's Linux screen capture technology

Post date: April 12, 2005, 18:04 Category: Miscellaneous Views: 3067 Comments
Tutorial quote: "I'd like you to help me find out about video screen captures," said one of my editors a while back. "Sure, let me see what's available," I replied. He pointed me to a couple of Web sites to get me started, and here I am a few weeks later ready to share my findings. I'll discuss ways that you can make video clips in Linux, talk about their applications and shortcomings. I'll also cover suitable ways to view your masterpieces once they're recorded.

Video screen captures are useful for jobs like application training, computer instruction, or product demos. An example would be the little one-minute video I set up for my wife. She kept forgetting how to start up Mozilla Mail on her Windows 98 machine. I captured the mouse clicks and screen changes (in real time) as I ran through the process, saving it to a Macromedia Flash file. I then created a little Web page on one of my Apache servers, that described how to start Mozilla Mail and included a link to the Flash file. Instead of asking me how to do it, she can now just click on the video tutorial.

How To Block Spam Before It Enters The Server (Postfix)

Post date: June 4, 2007, 23:06 Category: Security Views: 4956 Comments
Tutorial quote: The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

Virtual Users And Domains With Postfix, MailScanner, Mailwatch & MySQL On CentOS 5.1

Post date: March 9, 2008, 13:03 Category: Miscellaneous Views: 5731 Comments
Tutorial quote: This document describes how to set up a Postfix mail server that is based on virtual users and domains on CentOS 5.1 so that it works with MailScanner and Mailwatch. The resulting system provides a web interface (Mailwatch) where you can manage quarantined emails, train SpamAssassin, edit the white- and blacklist, view configuration files and the detailed MySQL database status.
