Probably not-- if the new license for Nessus 3 forbids commercial redistribution, then we won't be able to provide a package. However, the FreeBSD ports system has options to handle software which is under a restrictive license or distributed only as a binary. > [ ... ] The thing that seems germane > to the FreeBSD community is that ports, even extremely popular > ones, are > vulnerable, since under the GPL the AUTHOR of the code is not bound by > the same restrictions that the users are.

The author or copyright holder of software has the right to redistribute their software under other terms if they wish to do so; this has nothing to do with the GPL in particular, or even with creating derivative works in general. (One creates a derivative work when someone other than the original author makes changes to a work.) However, the GPL'ed version of the software, in this case Nessus 2, remains and will always remain available under the terms of the GPL. The decision to open source software is not revokable in that sense. People who are not happy with the direction Tenable is going with Nessus 3 could fork Nessus 2 and continue to develop it, if they choose to do so, with or without further contributions from Tenable. -- -Chuck
