This means that the license is not compatible with the GPL (a good thing, IMHO). (The GPL allows the author to be denied credit and in fact prohibits any license provision that would allow the author to insist upon getting credit for his hard work. Historically, this trait of the GPL is due to Stallman's contempt for BSD.) > A recent update, however, has added the following: > > Yes, this means that derivitive or modified works are not permitted > without the author's prior consent. > > That means, of course, that IPFilter is not free (or even open source) > software. But didn't he just give that consent immediately above? I don't see a problem. --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
