Hit send too soon :)
Have you disabled IPV6 on the box itself?
/etc/sysconfig/network, add: "NETWORKING_IPV6=no"
/etc/modprobe.conf, add: "alias net-pf-10 off"

Subject: Very OT: bind/named question
I've a caching nameserver configured on my recently built CentOS 5.x
mail server. The server is completely 'self-contained' as all mail and
related processes are local on the box; no gateways.
I recently configured a similar box with CentOS 4.x this past year and
have not seen this problem:
Dec 9 04:07:42 mxt named: FORMERR resolving
'foxnewsmail.com.spintlink.net/AAAA/IN': 126.96.36.199#53 Dec 9
04:08:39 mxt named: FORMERR resolving
I get many of these an hour. I'm not seeing real named problems, though.
Mail seems to be flowing okay.
What if anything can I/should I do about this?
I've performed some searches on this topic and see that this can be
related to IPV6 being enabled, but I believe I've disabled it. Also
mentions of lame servers being at approximately 60-some-odd-percent
Internet-wide and spammers with forged IPs causing these. That seems
more likely; did the authors of bind just change the error message for
lame servers to be more specific?
Your comments/suggestions appreciated.
