Package: bind9
Version: BIND 9.10.3-P4-Debian <id:ebd72b3>
Hello，Here maybe a bug after I upgrade my bind9.
Here my named.conf.options
options {
directory "/var/cache/bind";
forwarders {
8.8.8.8;
};
recursion yes;
dnssec-enable yes;
dnssec-validation auto;
dnssec-lookaside auto;
auth-nxdomain no; # conform to RFC1035
listen-on port 5300 { any; };
listen-on-v6 port 5300 { any; };
//allow-query { internal; };
};
When I set the listening port to 5300, A problem found by tcpdump when bind9
query to ROOT.
