SuSe Installing FreeNX Server on SUSE 10
Post date: December 27, 2005, 10:12 Category: Network Views: 125
Tutorial quote: Not long ago, I reviewed SUSE Linux 10 and found that they had included the latest version of FreeNX (a free version of NoMachine's NX Server) on the installation media. I'd never really tried FreeNX at that point but had heard some good things about it, so I thought I'd give it a shot. Well, once it was installed and working I have to say I was immediately impressed by how simple it was to setup and how well (read: fast) it performed over a WAN connection. I was literally able to get my desktop at home from anywhere else in the world and get near-local speed. Normally, working on a remote system is alright until you need to type in any shape or form. There was almost no delay from the time I'd press a key to the time it would show up on the screen. This is what sold me on FreeNX and prompted me to offer to write a HOWTO on the topic. I was overwhelmed with email from our readers asking that I write it... so here we are!

Debian Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV)
Post date: October 9, 2005, 14:10 Category: Network Views: 213
Tutorial quote: This document describes how to install a mail server based on Postfix 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.
