  • Autoresponders to accompany Virtual Users and Domains with Postfix, Courier and MySQL

    Author: todgermeTags: Comments: 5

    Autoresponders to accompany Virtual Users and Domains with Postfix, Courier and MySQL This guide focuses on making Yaa! (Yet Another Autoresponder!) work with Debian Sarge and the virtual users on Postfix tutorial (see http://www.howtoforge.com/virtual_postfix_mysql_quota_courier). The first thing to understand about the guide is that it uses the Virtual  Delivery Agent (VDA) and as a result any of the auto responders that you could use by passing them to a pipe via a .forward file simply won't work as the VDA does not support .forward expansions.  This limitation can be overcome via Procmail/Maildrop delivery but that is messy and slower especially for mail systems that are heavily used.  The simple answer is Yaa!

  • Setting Up A PXE Install Server For Multiple Linux Distributions With Ubuntu Edgy Eft

    VMWare Image Download Author: falkoTags: Comments: 14

    Setting Up A PXE Install Server For Multiple Linux Distributions With Ubuntu Edgy Eft This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 6.10 (Edgy Eft). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs. In this article I show how to configure a PXE server that allows you to boot multiple distributions: Ubuntu Edgy/Dapper, Debian Etch/Sarge, Fedora Core 6, CentOS 4.4, OpenSuSE 10.2, and Mandriva 2007.

  • screen: Keep Your Processes Running Despite A Dropped Connection

    Author: falkoTags: , Comments: 16

    screen: Keep Your Processes Running Despite A Dropped Connection I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labour. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task. This short tutorial shows how to use screen for just this purpose.

  • Enhance Your Mail Server With ASSP (Anti-Spam SMTP Proxy)

    Author: ovisTags: , Comments: 7

    Enhance Your Mail Server With ASSP (Anti-Spam SMTP Proxy) ASSP stands for Anti-Spam SMTP Proxy. The ASSP server project is an Open Source platform-independent transparent SMTP proxy server that leverages numerous methodologies and technologies to both rigidly and adaptively identify spam. In short ASSP is the most kickass solution that is both free and works great. It reduced spam to an absurd minimum for me.
