Netgraph-ATM used in Masters thesis

Hi, I saw some posts to the cvs-all mailing list recently, giving Harti Brandt a hard time for importing bsnmp to the FreeBSD source tree, so I thought I would post this. :) I recently used Netgraph-ATM as part of my masters thesis at Harvard Extension School, which looked at ATM, CORBA, and netw

WiFi intermittant cutout - IPv6

Hi all, I've noticed some odd and frustrating behaviour and am looking for some help. I have a 3 network setup for MIP6 (aka Kame snap of a few weeks ago). consider one section of the network. CN (host) <-> fec0:200:: <-> HN (router) <-> fec0:10:: <-> MN (host) the fec0:10:: network is an 802.

Confused about HyperThreading and Performance

Can someone point me at some non-marketing documentation about hyperthreading on the latest Intel chips? I'm seeing some strange performance measurements and I would like to figure out what they mean. My systems have the following CPU: CPU: Intel(R) Xeon(TM) CPU 1.80GHz (1799.81-MHz 686-class

Multiple IPs in Jail

Hey all - We patched mijail5 (http://garage.freebsd.pl/mijail.README) against RELENG_5_1. Most of the patch was successful with a little fuzz, except for a couple lines in jls which didn't patch due to cosmetic changes (easily fixed). Before the patch was applied, the jail environment
