Disable IPv6 The Right (Debian) Way
IPv4 has been in place for around 30 years now and is still a testament to human ingenuity. Unfortunately, IPv4 is limited to approximately 4.3 billion addresses, 0.0.0.0 - 255.255.255.255. As more cities in more countries get connected to the Internet, the address space is quickly being depleted. The use of NAT is a creative band-aid to help slow address exhaustion, but IPv6 is the new and improved IP addressing schema intended to replace IPv4.

iPhone4 vs HTC Evo – 3G and Has the WiFis
Know anyone with an iPhone? Are they anything like the chic in this video? Not only is the video hilarious, it also gave me an excuse to setup mod_flv_streaming. Despite the cartoon appearance the discussion is what some would consider, "adult language." Viewer discretion is advised... Also - almost forgot, more G-Bs and 3 wishes, even if one of those wishes is for the iPhone. Just watch and enjoy :]

Guest Submission: Howto Disable SSDP
SSDP - Simple Service Discovery Protocol - can actually turn out to be a disservice, if this protocol acts in the way pictured to the left. As you can see from the Wireshark capture, SSDP is causing some unnecessary congestion in my LAN; in fact, it's not unusual for SSDP to broadcast about 10 frames every couple of minutes. That's annoying, and if it's causing the same problem for you, the following instructions may help stop this spam.

Comment Posting Issue and Other Misc.
Unfortunately, if you've posted a comment to a Nullamatix.com post between July 24th and August 29th, they weren't submitted to the queue for approval. This was due to a php.ini setting modification in an effort to enhance security. My apologies if anyone wrote a novel during this time frame. The issue has been resolved and the comment submission form is now working as intended.

Howto: XCache in a Lighttpd Chroot on Debian
Whether you're pressed for resources on a virtual/dedicated server, or simply looking for ways to improve web application performance, XCache is guaranteed to produce the desired result. Within minutes of installing XCache: page load times were cut in half, PHP/MySQL RAM consumption was under control, and overall PHP rendering/output performance dramatically improved. In this post I'll go over the process of installing, configuring, and enabling XCache in a php5-cgi+Lighttpd chroot jail on a Debian Lenny web server.

DWM on Wikipedia Marked For Deletion
Anselm, the "inventor of dwm" shared this information with the suckless mailing list yesterday. Apparently, Wikipedia has flagged the dwm (dynamic window manager from suckless.org) article for deletion. Anselm says he's neutral and shared his thoughts on the Wikipedia Page, but what does this say about Wikipedia? A community built on free and open source software that promotes a free and "open" encyclopedia is now purging FOSS pages? Why, because Microsoft.com doesn't have anything to say about dwm?

Discontinued Security Support for Debian 4.0
One year after the release of Debian GNU/Linux 5.0 alias 'lenny' and nearly three years after the release of Debian GNU/Linux 4.0 alias 'etch' the security support for the old distribution (4.0 alias 'etch') is coming to an end next month. The Debian project is proud to be able to support its old distribution for such a long time and even for one year after a new version has been released.

New Tool: IP Range to CIDR
At least twice a week I find myself visiting ip2cidr.com, the IP to CIDR converter. Since the owner/author of the site hasn't release the source code, and I love a challenge, I developed my own version. The guys at the job find the tool useful, and after a few minor bug fixes, I've made the IP Range to CIDR tool available for use here at Nullamatix.com.
