Here are two quick notes on my favorite operating system. First, support for Stream Control Transmission Protocol (SCTP) has been added to FreeBSD CURRENT (i.e., 7.x). SCTP is a layer 4 alternative to TCP or UDP. I saw it mentioned in the final issue of Cisco's Packet magazine, in the context of NetFlow , specifically the new Flexible Netflow. When I get a chance to test this it will probably be using this technology.
Second, Federico Biancuzzi conducted an excellent interview with Robert Watson regarding OpenBSM and FreeBSD. This is incorporated into the upcoming FreeBSD 6.2, which I expect to see in early December.
