[Dnsmasq-discuss] OSX doesn't resolve addresses assigned by DHCP

[Ben Tisdall]

Hi,

I'm using dnsmasq 2.22-2 on Debian stable and am experiencing a problem with OSX
10.4.6 not resolving the address of a host that's been assigned by the dhcp
server. I don't really see how it's a dnsmasq issue but I'm otherwise pretty
stumped...

whitey:~ bentis$ ping sonny
ping: cannot resolve sonny: unknown host

And yet on the same machine:

; <<>> DiG 9.2.2 <<>> sonny
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27317
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;sonny.                         IN      A

;; ANSWER SECTION:
sonny.                  0       IN      A       192.168.0.18

;; Query time: 8 msec

;; WHEN: Tue Apr 25 18:25:49 2006
;; MSG SIZE  rcvd: 39

And resolution works fine from other machines on the LAN.

Now, if I add the host in question to /etc/hosts on the dnsmasq machine and
restart, resolution works and I can ping the machine by hostname from the mac.
However, the output from dig seems virtually identical:

/etc/dnsmasq.conf:

domain-needed

resolv-file=/etc/resolv-dhcp
local=/local/
address=/xxxxxxxxxx/192.168.0.2
address=/xxxxxxxxxx/192.168.0.245

dhcp-range=192.168.0.11,192.168.0.50,24h
dhcp-option=44,192.168.0.2  # set netbios-over-TCP/IP nameserver(s) aka WINS
server(s)

dhcp-option=46,8           # netbios node type
dhcp-option=47             # empty netbios scope.

Any ideas?

Thanks,
