FreeBSD Configuring virtual domains with Cyrus+Postfix in FreeBSD 5.4
Post date: November 30, 2005, 21:11 Category: Software Views: 2147 Comments: 0
Tutorial quote: Cyrus IMAP is an efficient IMAP server capable of handling a large number of accounts. Its biggest drawback is getting it installed and configured. This tutorial is a step-by-step guide on how to use Cyrus with the Postfix mail transfer agent (MTA). I tested these instructions with FreeBSD 5.4.

Postfix is a replacement for sendmail, the stock MTA that comes in FreeBSD. It is easier to configure and manage than sendmail. If you depend on sendmail, you can still look at the article for the Cyrus part, but you'll need to look elsewhere for the MTA configuration.

Unless otherwise instructed, perform all operations in this tutorial as root. You will need to use the port system. If you are new to it, check Chapter 4 of the FreeBSD Handbook.

FreeBSD Using FreeBSD's ACLs
Post date: September 29, 2005, 12:09 Category: Security Views: 1218 Comments: 0
Tutorial quote: Five years ago (gee, has it really been that long?), I wrote a series of articles on understanding Unix permissions. Since then, FreeBSD has implemented something known as ACLs (Access Control Lists).

ACLs came to BSD as part of the TrustedBSD project. As the name suggests, they give a user finer access control over permissions.

Linux Building a Linux virtual server
Post date: June 9, 2005, 09:06 Category: Software Views: 1124 Comments: 0
Tutorial quote: With the explosive growth of the Internet, the workload on servers providing Web, email, and media services has increased greatly. More and more sites are being challenged to keep up with the growing demands and are employing several techniques to avoid overloading their servers. Building a scalable server on a cluster of computers is one of the solutions that is being effectively put to use. With such a cluster, the increasing requests can be easily managed by simply adding one or more new servers to the existing cluster as required. In this article we will look at setting up one such scalable, network load-balancing server cluster using a virtual server via the Linux Virtual Server Project.
Unix+clones File Transfer Protocol
Post date: April 12, 2005, 13:04 Category: Network Views: 784 Comments: 0
Tutorial quote: Wake up, you goodness-to-GUI slacksters! It's time to get up and get out of that hammock and put your feet on the ground and your hands on the CLI. This week we're going to talk about data in motion. Taking a file from one place on the network. Putting it someplace else. Most often today some form of FTP, the File Transfer Protocol, is used to do those things. It's been part of the Internet since there was an Internet.
FreeBSD FreeBSD Networking Basics
Post date: April 12, 2005, 19:04 Category: Network Views: 1510 Comments: 0
Tutorial quote: Beginners to Unix-like operating systems such as FreeBSD are often stymied by their network settings. Sure, the install process may have set up your NIC for you, but where do you go to view these settings, and how do you proceed if your NIC stops working? Since networking is such an integral part of computing, this article will demonstrate how to verify, configure, and optimize your network settings.
Linux Linux stateful firewall design
Post date: April 12, 2005, 12:04 Category: Network Views: 785 Comments: 0
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.
Unix+clones Using Gmail as GNOME’s default mailer
Post date: May 17, 2006, 10:05 Category: Desktop Views: 895 Comments: 0
Tutorial quote: I started using Gmail as my primary mail application a little over a year ago. For the most part, it has been a pleasurable experience. However, to my knowledge there has not been a simple way to make Gmail your default mailer in GNOME. There are firefox extensions that implement this functionality, but I used epiphany and the functionality does not extend to the entire GNOME desktop.
