Hi,
I have an Dial-on-Demand Connection configured on that computer. My
Bind8 Nameserver does every 4sec. a DNS-Querry. Tcpdump -i sl0 show´s
that:
21:01:16.858929 fw.home.net.61002 > 202.12.27.33.domain: 3816 NS? . (17)
21:01:20.858929 fw.home.net.61002 > 192.112.36.4.domain: 3816 NS? . (17)
21:01:24.858929 fw.home.net.61002 > 128.63.2.53.domain: 3816 NS? . (17)
Why does my NS that querrys?!?

I tryed the root.hint like in the DNS-HOWTO described:
--zip--

=2E 6D IN NS B.ROOT-SERVERS.NET.
=2E 6D IN NS C.ROOT-SERVERS.NET.

C.ROOT-SERVERS.NET. 5w6d16h IN A 192.33.4.12

After a restart of bind8, the permanent querrys were gone but the NS
can´t answer querry´s like www.linux.de.
Can anybody help me, please!
