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 ?
