mod_security, Client-Side Mail Filtering, and Graphy Word Puzzlesby chromatic
Linux Newsletter for 12/01/2003
Hello and welcome to the first Linux newsletter of December 2003. While family members are shopping, baking, and otherwise preparing for the holiday season, let's see what's new in the world of open source development, administration, adoption, and usage this week.
Let's ease into the month with something gentle. Oracle author Andrew Odewahn recently delved into the interesting (if esoteric) world of graphing. That's when he accidentally invented a new style of puzzle called RouteWord. Introducing RouteWord explains a bit more of the theory and the rules. ONLamp and Andrew are also proud to run one puzzle every day throughout the month of December.
If you'll be spending time away from home in the coming month, you may have to put up with slower-than-normal bandwidth. You also may have to do tech support for relatives who may not be quite ready for a nice Linux or BSD desktop. Chances are, they do know and dislike spam, though they may not know what to do with it. That's where KIVILCIM Hindistan's Client-Side Mail Filtering with SaveMyModem comes in. If you're not quite ready to migrate your relatives to a mail server under your control, you can help them get a handle on filtering out unwanted email while being gentle on their bandwidth.
Finally, the upcoming holiday season represents a huge commercial opportunity for online vendors. As well, the school break means that there may be quite a few adolescent troublemakers with free time on their hands. If you care about your data, you want as much security as possible. That's why Ivan Ristic created mod_security, an Apache module that can log, detect, and deny suspicious actions. Read more about it in Introducing mod_security.
This week's new weblogs feature Chris Adamson extolling the virtues of iComic (but more importantly, kicking off a discussion on the benefits and tradeoffs of using a comic reader versus viewing the web page); William Grosso discussing Sleepless Software's unique business model for making money off of games; Steve Mallett wondering what to hack on during holiday; Ethan Cerami discussing RESTful error handling; and Andy Lester pointing to the 2003 Perl Advent calendar.

Using and Customizing Knoppix
Several Linux distributions boot directly from CD-ROMs. How many are usable in that state? How many are customizable in that state? Klaus Knopper's Knoppix is perhaps the best known of these distributions. Robert Bernier explains how to use Knoppix and how to customize your own self-booting distribution CD.
Using Linux as a Small Business Internet Gateway
Internet access is vital to many small businesses. Creating a reliable and worry-free connection used to be difficult. With good software such as the Linux kernel, wvdial, Squid, Postfix, and iptables, it's reasonably easy to set up Linux as an Internet gateway. Alexander Prohorenko explains how.
Installing Oracle 9iR2 on Red Hat 9
While Oracle's understandably proud of their Linux support, Oracle 9i is unsupported on the latest and greatest Red Hat. That doesn't mean it doesn't work, just that you'll have to do a little tinkering. Roko Roic demonstrates how to install Oracle 91R2 on Red Hat 9.
Every layer of security you can add is one more deterrent for the bad guys. Writing (or choosing) secure code is important, but it's not the only defense. Ivan Ristic, creator of mod_security, explains how this Apache module can turn back potential attacks before they reach your code.
