I need to permanently shut down one of our DNS servers. This machine is located remotely using an IP address that can not be easily moved. The problem is that lots of users have stuck it's IP address into thir resolv.conf files or Win95/98 registries. I wrote some daemons that camp on a bunch of machines and track DNS utilization by user (don't ask :-). Repeated email messages and even phone calls have not convinced them to change their setup. Now, I could just shut it off but all the web surfers will see a long pause on every page and they'll complain. Doable but ugly. So, here's my thought. Drop a program on this machine that examines every DNS lookup. If the hostname starts with "www.", we'll assume they are browsing and return a fixed IP address that, regardless of URL, points to a page that says "Fix your machine" and gives instructions. If the hostname is anything else, return normal DNS. This looks to be a non-trivial hack. I'm wondering if anyone has already solved this problem? /\/\ \/\/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
