I've been doing sysadmin work on unix boxes, and network layer gear like routers, firewalls, and load balancers for a long... long time. Check out my linked-in profile for more on that. Systems monitoring and spam mitigation are a couple areas I've done some work worthy of attention. I wrote a book about systems monitoring with Nagios, an open source monitoring framework, and write the monthly monitoring column for Login Magazine.

It's like letting you see my underpants, sure they're very nice underpants, but at the same time they give you insight that I'd rather you didn't have (if it's all the same to you). So the code that appears herein is the stuff that I've found SO useful I couldn't help but share it. text/html 2010-01-04T16:40:31-05:00 http://www.skeptech.org/doku.php?id=faldentify&rev=1262644831&do=diff Faldentify The pages in this context are an attempt to coalesce myriad notes I've collected on the subject of identifying various clones of the FN-FAL main battle rifle.

It's not as straightforward as you probably think it is. PF has upper-level limits on stuff PF is a kernel process, and so will not automatically allocate RAM for itself. As such, it has several important hard-limited memory buffers you should increase if you're going to run BSD in a production environment. If you hit any of these limits, PF will either crash, drop packets, or hand out 'no… text/html 2010-05-02T23:12:18-05:00 http://www.skeptech.org/doku.php?id=photography&rev=1272859938&do=diff Photography This is a landing page for hobby #1432 (photography).
