Hello,
I have setup dynamic dns updates from a cisco router which is handing
out dhcp addresses. In the debug's i'm getting messages that say
REFUSED and SERVFAIL when trying to do a dynamic update.
I'm unsure as to where the problem lies, but I think it might have to
do with the security on the BIND server. I have added the networks to
the zone via the allow-update option. But whatever I try I still get
the REFUSED error on the router.
Here is my config:
acl ecs {
172.16.56.0/21;
};
acl home {
192.168.75.229;
};
acl slaves {
172.16.200.151;
192.168.75.115;
};
options {
directory "/etc";
pid-file "/var/run/named/named.pid";
forwarders {
142.161.130.155;
142.161.2.155;
};
notify yes;
allow-recursion {
172.16.0.0/16;
192.168.75.0/24;
};
query-source address 172.16.200.150;
sortlist {
{ 192.168.75/24;
{ 172.16.88/21; };
};
{ 172.16.56/21;
{ 172.16.56/21; };
};
};
};
zone "16.172.in-addr.arpa" {
type master;
file "/var/named/172.16.rev";
notify yes;
also-notify {
172.16.200.151;
172.16.56.250;
};
};
zone "tech.net" {
type master;
file "/var/named/tech.net.hosts";
notify yes;
also-notify {
172.16.200.151;
172.16.56.250;
};
};
zone "me.net" {
type master;
file "/var/named/me.net.hosts";
also-notify {
172.16.200.151;
192.168.75.115;
};
notify yes;
};
zone "." {
type hint;
file "/var/named/root.db";
};
zone "168.192.in-addr.arpa" {
type master;
file "/var/named/192.168.rev";
};
zone "ecs.net" {
type master;
file "/var/named/ecs.net.hosts";
};
zone "me.com" {
type master;
file "/var/named/me.com.hosts";
};
zone "dan.net" {
type master;
file "/var/named/dan.net.hosts";
allow-update {
192.168.75.1;
172.16.56.111;
192.168.75.31;
};
};
controls {
};
The zone i'm trying to send dynamic updates to is the last one.
Thanks,
Dan.
