Adding Atom 1.0 Support to RSS Sites
I switched to Atom 1.0 on Workbench two months ago, a move that hasn't been as smooth as I'd like because of one popular aggregator that doesn't support the format. This site is created using Wordzilla, a LAMP-based weblog publishing tool that I've developed over the last year. Writing code to generate Atom feeds in PHP was extremely simple, since most of the code used to generate RSS feeds could be applied to the task. Atom uses a different format for date-time values than RSS, so I had to write new ... read more
Moving from Manila to Movable Type
Craig Jensen's long-running BookNotes weblog has fallen on hard times since the move from Weblogs.Com to Buzzword.Com in 2004. His site lost its Google pagerank and he's had trouble rebuilding his audience. As the first step in retiring free Manila hosting on Buzzword.Com, I'm helping him transfer the weblog to Movable Type, because I have a five-user commercial license that's going to waste on Workbench and I'd like to encourage a fellow liberal and bibliophile to keep blogging. Jason Levine's Frontier script ... read more
Stopping Open Recursion Name Server Attacks
I received an ominous e-mail from my server host Thursday: The DNS service(s) on your server are currently open to recursive queries from the world, leaving them vulnerable to DNS cache poisoning attacks and allowing them to be used to attack other sites. Your server was reported participating in an outbound DDoS attack through means of this vulnerability by an attacker. Please ensure that recursive lookups are DISABLED in yournameserver's configuration to prevent future abuse. If you need any assistance with ... read more
UserLand Frees Up Manila Servers
UserLand Software is discontinuing free Manila hosting, as I discovered last week when one of their users sought refuge on Buzzword.Com. Edit This Page shut free service on Dec. 1 and ManilaSites will do the same Dec. 31. I can offer free hosting on Buzzword, but webloggers who are committed to publishing with Manila should be advised that I'm migrating the server to new software by May 1, 2006. A better long-term option for those folks is to subscribe to Weblogger.Com or UserLand. (As an aside, if you're a fan ... read more
My Name Server is Totally Lame
I started the day with a dead name server that knocked more than 100 sites offline, including Workbench, the Drudge Retort and all of the Buzzword.Com bloggers. I've been using BIND for years and thought I had run out of interesting new ways to break it. Overnight, most name requests failed and my server log filled up with errors like this: lame server resolving 'www.cadenhead.org' (in 'cadenhead.org'?): 67.19.3.218#53 A lame server is one that's not responding to a name request it is expected to handle. ... read more
My Reign as the King of Pings
I've been running Weblogs.Com since June for Dave Winer, who wanted to see if service performance could be improved as he began to receive seven-digit inquiries about selling it. Weblogs.Com ran on Frontier for six years from its founding in 1999, handling the load reasonably well until the number of pings topped one million per day within the last year. In a frenzied weekend, I recoded the site as an Apache/MySQL/PHP web application running on a Linux server, writing all of the code from scratch except for ... read more
I own a Linksys WRT54G, a 802.11g wireless access point, router, and four-port 10/100 Ethernet switch that runs Linux. InfoWorld columnist Robert X. Cringley singes the praises of the WRT54G, which is an amazing little Linux device that can be hacked to function as an Internet server. I've been using it on a Windows XP network to share a broadband Internet connection over several wired and wireless PCs around the house. As amazing as this device is, I learned something this morning: Even when you have reset the ... read more
