Post date: April 24, 2005, 20:04 Category: System Views: 4248 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.

VNC (Virtual Network Computing) 101

Post date: April 16, 2005, 00:04 Category: Network Views: 3770 Comments
Tutorial quote: VNC stands for Virtual Network Computing. It is remote control software which allows you to view and interact with one computer (the "server") using a simple program (the "viewer") on another computer anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home. VNC is freely and publicly available and is in widespread active use by millions throughout industry, academia and privately.

LDAP Authentication In Linux

Post date: August 26, 2006, 06:08 Category: Security Views: 5614 Comments
Tutorial quote: This howto will show you howto store your users in LDAP and authenticate some of the services against it. I will not show howto install particular packages, as it is distribution/system dependant. I will focus on "pure" configuration of all componenets needed to have LDAP authentication/storage of users. The howto assumes somehow, that you are migrating from a regular passwd/shadow authentication, but it is also suitable for people who do it from scratch.

Share Directories via AFP

Post date: October 20, 2006, 17:10 Category: Network Views: 7427 Comments
Tutorial quote: This HOWTO is mainly geared towards PPC users or users who need to share files between Linux and Tiger 10.4. As you're probably aware, Apple SMB is broken in Tiger and God only knows how long it'll take them to fix it. So this is an alternative that's both easier and provides faster file transfers under OS X's native file transport protocol, AFP (Apple File Protocol).

Virtual Users And Domains With Postfix, Courier And MySQL (Fedora 8)

Post date: November 20, 2007, 10:11 Category: Installing Views: 3472 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 will 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 will 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.
