Post date: April 12, 2005, 18:04 Category: Network Views: 2346 Comments
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.

Using FreeBSD's ACLs

Post date: September 29, 2005, 17:09 Category: Security Views: 3484 Comments
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.

Using Gmail as GNOME’s default mailer

Post date: May 17, 2006, 15:05 Category: Desktop Views: 2925 Comments
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.

Lightweight Web Serving with thttpd

Post date: December 1, 2005, 00:12 Category: Software Views: 7801 Comments
Tutorial quote: The Apache HTTP Server is the most popular web server due to its functionality, stability, and maturity. However, this does not make it suitable for all uses: slow machines and embedded systems may have serious problems running it because of its size. Here is where lightweight HTTP servers come into play, as their low-memory footprints deliver decent results without having to swap data back to disk.

Similarly, these small HTTP servers are suitable to serve static content efficiently so as to allow Apache, mod_perl, mod_python, or even servlet containers to handle dynamic requests without tying up memory-hungry children to serve small images. In other words, these applications can serve as a complement to your existing full-featured web server, not as a replacement.

One of these servers is thttpd, a simple, small, portable, fast, and secure HTTP server. Among its features are support for the HTTP/1.1 standard, CGIs, virtual hosts, and IPv6. This article shows how to install and configure this software under NetBSD. I chose NetBSD not only because it is my preferred OS, but also because it has the ability to run on the most disparate old hardware, where thttpd shows its strengths. I had a Macintosh Performa 630 (a 68LC040 chip at 33MHz) running NetBSD/mac68k 2.0 with thttpd on top of it, serving pages to my home network nicely.

How to set up a home DNS server

Post date: December 17, 2006, 17:12 Category: Network Views: 10114 Comments
Tutorial quote: In the first part of this series on the Domain Name System (DNS), we set up a caching nameserver that allowed our clients to take advantage of faster network operations by caching frequently requested DNS queries. In this article, we will extend our caching nameserver to a master nameserver that is responsible for managing the authoritative information for our internal client hostnames.
