Extrusion for Linux and FreeBSD have just gone stable.

    Extrusion is a project we invented to assist in the detection of miscreants attempting to use your system in an illegal manner. It detects outgoing UDP floods, outgoing portscans, and RAW SOCKET attempts. It logs the user's uid and the command issued to produce the result.

    Currently Linux and FreeBSD are supported, OpenBSD is in beta and solaris is planned. We would apprecienate any feedback you have for us wether it be problems/crashes, features you would like to see, or lack of problems. You can email us at lockdown@lockeddown.net and josh@pulltheplug.com.
