Something has changed in our DNS services that is blocking nfs mounts.
From the client I get:
mount: amparotech:/data3/qcdm failed, reason given by server: Permission
denied
In the log file of the server I get:
<date/time> orasrv rpc.mountd: refused mount request from 192.168.1.5
(luke.168.192.in-addr.arpa) for /data3/qcdm (/data3/qcdm): no DNS
forward lookup
note 1: amparotech is the DNS entry for the orasrv box
note 2: I'm getting the same error between boxes who's DNS name matches
the hostname of the server as well
If I ping amparotech from luke I get:
# ping amparotech
PING amparotech.gwic.net (192.168.1.48) 56(84) bytes of data
64 byts from amparotech.gwic.net.168.192.in-addr.arpa (192.168.1.48):
icmp_seq=1 ttl=64 time=0.153 ms
which looks to me like it forward resolved correctly.
If I dig from luke I get the following:
# dig amparotech.gwic.net
;<<>> Dig 9.2.1 <<>> amparotech.gwic.net
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60751

amparotech.gwic.net. 86400 IN A 192.168.1.48
;; AUTHORITY SECTION:
gwic.net. 86400 IN NS ns.gwic.net.
To me this shows forward resolution is working.
If I dig -x 192.168.1.5, I get:
; <<>> DiG 9.2.1 <<>> -x 192.168.1.5
;; global options: printcmd
;; Got answer:

;; AUTHORITY SECTION:

ns.gwic.net.168.192.in-addr.arpa.
If I understand dig, this show reverse resolution working as well.
Can anyone help me resolve this issue. I'm running in the "I hope I
don't have to reboot" mode, otherwise I will loose all of my nfs shares
between all computers in my server farm.
