Reverse DNS lookups failing

[dom9inic]

Hi all,

Has anyone seen an issue where upon installing a fresh copy of Jaguar server on an Xserve with an additional PCI Ethernet card reverse DNS will fail.

I install, step through the setup giving fqdn in relevant places then specify static IPs for both NICs but assign the Bult In NIC the IP associated in the A record on our external DNS server.

Still when I reboot and do a dig, the PTR record is fine but the reverse lookup fails with an error

; <<>> DiG 8.3 <<>> @10.102.3.5 kt-macserve.xxxxxxxx.xx.xx
; (1 server found)
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 6

I’m not sure what the problem is here.

The odd thing is, if I leave the secondary NIC with the DHCP address the install assigns it, reverse lookups succeed on that dynamic IP.

Any clues?

Hey There…

As I understand it, PTR records are reverse records. So if PTR records are working then you should be fine. What DNS server do you have specified for the second Nic?

Can you post the full dumps or post just simple nslookups? That may shed some light..

Thanks!

Thanks for the response Z, it’s now fixed. The fix was the Win2K admin recreating the PTR records for the server, now all is well.

Thanks for the input.

That would do it.
Have a great week.

Regards,
