Using: FreeBSD 2.1.7.1-RELEASE I have a problem with "nslookup" and "DNS". I am using an IP addressing scheme proved by an ISP which has the class C network subnetted down to 16 hosts. Here is a brief description of the bug: DNS server is up and running DNS server resolves for the domain. nslookup on pc clients works perfectly. nsllokup on the freebsd machine fails to find the server. Secondary DNS server fails to find the primary server (it can ping it) IP Information: IP address and subnet mask: network=209.61.45.96 mask=255.255.255.240 host=209.61.45.98 ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 209.61.45.98 netmask 0xfffffff0 broadcast 209.61.45.111 Ping tests (hostname is "shaka") PING shaka.initium.com (209.61.45.98): 56 data bytes 64 bytes from 209.61.45.98: icmp_seq=0 ttl=255 time=0.349 ms resolv.conf file: shaka% cat resolv.conf domain initium.com nameserver 209.61.45.96 nslookup failure: shaka% nslookup *** Can't find server name for address 209.61.45.96: No response from server *** Default servers are not available Now, further testing reveals that when I point thefreebsd client to 0.0.0.0 nslookup works fine. shaka% cat resolv.conf domain initium.com nameserver 0.0.0.0 shaka% nslookup Default Server: shaka.initium.com Address: 0.0.0.0 > shaka Server: shaka.initium.com Address: 0.0.0.0 Non-authoritative answer: Name: shaka.initium.com Address: 209.61.45.98 Is this a bug or a configuration error ?
