Thank you for the scrip. I will then asign a single main ip to the interface in rc.conf and then run this script from /usr/local/etc/rc.d because i think rc.local is merged after each cvp/buildworld/installworld/mergmaster, so /usr/local/etc/rc.d is a safer place to to keep it. Right or not? The other question, will assigning 200+ ip addresses degrade tcp/ip perfomance noticeably? How to i spell noticably or noticaebly? :) Regards, Artem _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
