DHCP3-Server doesn't request a zone update

DHCP3-Server doesn't request a zone update

Post by Markus Fel » Wed, 30 Sep 2009 18:08:10


Hi All,

i am trying to get my Debian Lenny Server running with DNS, DHCP, NFS
and CUPS. My DNS- and DHCP-Server is up and running, but it seems that
my DDNS doesn't work. I am using DCHP-Server version 3.1.1-6+lenny and
BIND9.5.1.dfsg.P3-1.

My client is debian Lenny too and it gets an IP address. In my syslog
doesn't appear anything about update, neither a bad authentication failure.

DHCP-Message: http://www.yqcomputer.com/

BIND-Message: http://www.yqcomputer.com/

I have the following zones:
/etc/bind/db.0 http://www.yqcomputer.com/
/etc/bind/db.0.168.192 http://www.yqcomputer.com/
/etc/bind/db.127 http://www.yqcomputer.com/
/etc/bind/db.255 http://www.yqcomputer.com/
/etc/bind/db.empty http://www.yqcomputer.com/
/etc/bind/db.feldland.lan http://www.yqcomputer.com/
/etc/bind/db.local http://www.yqcomputer.com/
/etc/bind/db.root http://www.yqcomputer.com/
/etc/bind/named.conf http://www.yqcomputer.com/
/etc/bind/named.conf.local http://www.yqcomputer.com/
/etc/bind/named.conf.options http://www.yqcomputer.com/
/etc/bind/zones.rfc1918 http://www.yqcomputer.com/

Config of my DHCP-Server:
/etc/dhcp3/dhcpd.conf http://www.yqcomputer.com/

There was a Permission denied message, which i already solved, by
changing the permissions.

When my client connects to my DHCP-Server, the server shall update the
zone of my client, but there is no message conataining the word update.

Has someone any idea ?

regards Markus

This is a multi-part message in MIME format.

Hi Markus,

check the dhcpd.log for the following messages:

I.e.

adding:

Sep 30 15:13:06 ns1 dhcpd: Added new forward map from
172-17-111-249.example.net to 172.17.111.2
49
Sep 30 15:13:06 ns1 dhcpd: added reverse map from
249.111.17.172.in-addr.arpa. to 172-17-111-249.
example.net


removing:

Sep 30 15:20:04 ns1 dhcpd: if NB4711.example.net. IN TXT
"315bd896018c77e02f3f9f43a6fb4e5fe1
" rrset exists and NB4711.example.net. IN A 172.27.13.158 rrset exists
delete NB4711.example.net. IN A 172.27.13.158: success.
Sep 30 15:20:04 ns1 dhcpd: if NB4711.example.net. IN A rrset doesn't
exist delete NB4711
.example.net. IN TXT "315bd896018c77e02f3f9f43a6fb4e5fe1": success.
Sep 30 15:20:04 ns1 dhcpd: removed reverse map on
158.13.27.172.in-addr.arpa.


And depending on your logging of the DNS-Server the corresponding entries:

30-Sep-2009 15:13:06.111 update: info: client 172.17.111.16#58580:
updating zone 'example.net/IN': update unsuccessful:
172-17-111-249.example.net: 'name not in use' prerequisite not satisfied
(YXDOMAIN)
30-Sep-2009 15:13:06.131 update: info: client 172.17.111.16#58581:
updating zone 'example.net/IN': deleting rrset at
'172-17-111-249.example.net' A

Where the 172.17.111.16 is the address of the dhcp-server


Regards

Holger
