    Author: Falko TimmeTags: Comments: 1

    Postfix-SMTP-AUTH-TLS-Howto This document describes how to install a mail server based on postfix that is capable of SMTP-AUTH and TLS. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. I tested it on Debian Woody and Fedora Core 1 so far.

    Chkrootkit-Portsentry-HowtoThis document describes how to install chkrootkit and portsentry. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems. Chkrootkit "is a tool to locally check for signs of a rootkit" (from http://www.chkrootkit.org). "The Sentry tools provide host-level security services for the Unix platform. PortSentry, Logcheck/LogSentry, and HostSentry protect against portscans, automate log file auditing, and detect suspicious login activity on a continuous basis".

    Debian-Kernel-Compile-Howto (Kernel 2.6) In some cases you might want to compile your own kernel that suits your needs better than the standard kernel that comes with your distribution. I will describe how to do this on a Debian Woody machine (a description for Debian Sarge can be found here!). Please note that this tutorial is for kernel 2.6 only! A tutorial for kernel 2.4 can be found here.

    Author: Falko TimmeTags: Comments: 1

    Creating Images Of Your Linux System With SystemImagerHave you ever had the problem that you have set up the "perfect system", and now you want to back up this system before you make changes to it so that you can restore the original state if you changes are not satisfying? Or are you a system administrator in a large company where you have to maintain hundreds of Linux machines that run exactly the same software, but are sick of installing each machine manually? Or did you develop a Linux-based hardware appliance, and now you want to sell it in big numbers on different hardware platforms (i.e., different hard disks, etc., not different processor architectures!) without having to maintain an image for each platform? Or do you want to distribute this solution to

  • Virtual Hosting with Postfix, part one

    Author: joeTags: Comments: 9

    Version 1.0 Author: Joe Topjian <joe [at] adminspotting [dot] net> Last edited 04/11/2005 The virtual domain support in Postfix is actually quite robust. There are three different ways you host virtual domains with Postfix and they're all described here. We'll be looking at the third one: separate domains and non-unix accounts. Why this one? Because in the end, this options gives us the most flexibility. It's a little more complicated to set up and understand but well worth it when you're hosting several domains.

  • Virtual Hosting with Postfix, part two

    Author: joeTags: Comments: 3

    Version 1.0 Author: Joe Topjian <joe [at] adminspotting [dot] net> Last edited 04/15/2005 This article will pick up where the last one left off: how to actually retrieve the email we're storing in our virtual accounts. In the first article, I explained how we're using the third type of Postfix virtual hosting which is to use separate domains and non-unix accounts. The separate domains portion was covered fairly well. Now it's time to work on the non-unix accounts.
