Hi guys
am needing some help, am using bind to provide the DNS backend for samba
using dlz resolution works well however!!
my clients are not able to update the registered DNS entries
when running samba_dnsupdate against the samba DLZ named server
am getting
; Communication with 127.0.0.1#53 failed: timed out
could not talk to any default name server
Failed nsupdate: 1
Then bind stops responding completely and the server has to be reset to
resolve it.
can somebody give me a hit to whats wrong as everything on wiki is in.
below is the servers named.conf file
acl "xfer" {
none;
};
acl "trusted" {
127.0.0.0/8;
::1/128;
192.168.0.0/16;
172.16.0.0/16;
};

pid-file "/var/run/named/named.pid";
empty-zones-enable no;
allow-update {trusted;};
version none;
hostname none;
server-id none;
listen-on-v6 { ::1; };
listen-on { 127.0.0.1; 172.16.10.250;};
allow-query { trusted;};
allow-query-cache { trusted;};
allow-recursion {trusted;};
allow-transfer {none;};
