There have been no replies on this newsgroup. I looked at the BIND 9
Users newsgroup, and there was a similar posting. I am posting my
problem here (instead of to bind9-users) because I am subscribed to
this list, and I assume that the same level of expertise is available
here as there. Is there a need for two different newsgroups?
The responses on bind9-users were
1) Change the firewall to accept DNS packets from a high-numbered
UDP port.
2) See transfer-source, notify-source and query-source to let BIND
not use a high-numbered UDP port.
I do not have a firewall between my DNS server titania (aka
dns1.anl.gov) and some of my masters. I ran a number of sniffer traces,
and in each case I saw BIND 9.2.1 on dns1 send SOA queries from a
high-numbered UDP port to port 53 on each master. In the trace, which
was taken on a router port that spanned the dns1 addresses, I saw
responses for each of the SOA queries returning from port 53 on the
masters to the high-numbered port on the slave dns1. Is there any
reason why BIND would not be seeing these return responses? Do I
need to change anything in the BIND configuration file? After I have
finished with my testing (when the initial set of refresh failure
messages stop appearing in syslog), then I stop 9.2.1 with rndc,
edit the named.conf file to comment out the rndc key statements,
copy the BIND 8.2.5-REL executable back to named, and restart 8.2.5.
Note that dns1 is a Solaris 5.6 machine (soon to be 5.8) with three
Interfaces. Is there a problem because I have multiple interfaces?
Thanks.
