While I agree with the original poster that you are missing some data, I also agree that talking to the "vendors" of tcpdump is a better way. Peter, if you are keen on it, submit a port (net/tcpdump39) which gives you the old functionality and alert me about it. Edwin, who at least now knows why tcpdump on 8.0B3 did look so trange. -- Edwin Groothuis Website: http://www.mavetju.org/ ed...@mavetju.org Weblog: http://www.mavetju.org/weblog/ _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
