LinuxReality.com (a site with Linux related podcasts – similar to the BSD focused bsdtalk.blogspot.com) has posted a podcast (episode 84) that focuses on Linux and (network) security. In this episode Paul Asadoorian and Larry Pesce of the Pauldotcom Security Weekly Podcast are interviewed.
Amongst the many things discussed, M0n0wall and pfSense are also mentioned.
The FreeBSD network stack virtualization project aims at extending the FreeBSD kernel to maintain multiple independent instances of networking state. This will allow for complete networking independence between jails on a system, including giving each jail its own firewall, virtual network interfaces, rate limiting, routing tables, and IPSEC configuration. This project is focused at virtualizing the networking stack in FreeBSD -CURRENT.
