How To Implement SPF In Postfix

Post date: February 25, 2007, 21:02 Category: Miscellaneous Views: 4646 Comments
Tutorial quote: This tutorial shows how to implement SPF (Sender Policy Framework) in a Postfix 2.x installation. The Sender Policy Framework is an open standard specifying a technical method to prevent sender address forgery. There are lots of SPF extensions and patches available for Postfix, but most require that you recompile Postfix. Therefore we will install the postfix-policyd-spf-perl package from openspf.org which is a Perl package and can be implemented in existing Postfix installations (no Postfix compilation required).

Rebuilding the OpenBSD kernel

Post date: April 24, 2005, 20:04 Category: System Views: 4087 Comments
Tutorial quote: Users who want their OpenBSD machine to perform specific functions or need additional device drivers might want to customize their kernel. In other OS's, like some types of Linux, it is very popular to rebuild the kernel because the default is so bloated. For most users, the default OpenBSD kernel is sufficient; however, you should still apply kernel patches, which will require rebuilding and installing a fresh kernel.

Apt-Cacher-NG - HTTP download proxy for software packages

Post date: February 24, 2009, 07:02 Category: System Views: 3808 Comments
Tutorial quote: Apt-Cacher-ng is a software package that keeps a cache, on the disk, of Debian/Ubuntu Packages and Release files.When an apt-get like client issues a request for a file, Apt-Cacher intercepts it and if the file is already cached it serves it to the client immediately, otherwise it fetches the file from the Internet, saves it on the cache, and then serves it to the client. This means that several Debian machines can be upgraded but each package need to be downloaded only once.

Automated distributed backups for laptops

Post date: February 14, 2006, 21:02 Category: Network Views: 2558 Comments
Tutorial quote: This document will describe the setup I made for automating the backup tasks for all laptops here in the house. My servers use the same backup server and infrastructure, but right now they don't have the checks and scripts because they are online 24/7 and my backup server is triggering the backup process. This is however not true at all for the laptops.

Laptops can be at different places, powered down, suspended, put to sleep etc. So I needed a different approach for them.

Enhancing kernel security with grsecurity

Post date: November 25, 2005, 21:11 Category: Security Views: 2849 Comments
Tutorial quote: Is your server as secure as it could be? Sure, you use a firewall, mandate strong passwords, and patch regularly. You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks. If these possibilities keep you awake at night, you're not alone. The sleepless folks with the grsecurity project have developed an easy-to-use set of security enhancements to help put your fears to rest.
