Hello, <br>I have some doubts regarding the dhcp server behaviour when
configured to do dns updates. I have read the manuals and googled for a
while but something remains unclear to me. <br><br>Some of my current settings in dhcpd.conf:<br>
<br>ddns-updates on;<br>do-forward-updates on;<br>ddns-update-style interim;<br>ddns-domainname "<a href="http://xxx.com/" target="_blank">xxx.com</a>.";<br>ddns-rev-domainname "<a href="http://reverse.xxx.com/" target="_blank">reverse.xxx.com</a>.";<br>
deny client-updates;<br>update-static-leases on;<br>update-optimization off;<br>use-host-decl-names on;<br><br><br>So,
when a dhcp client sends a fqdn in its request, the server ignores the
provided fqdn and uses the "option host-name" defined in the host
declaration to update my dns server, which is fine since I put "deny
client-updates".<br>
<br>On the other hand, if the client doesn't send a hostname, no dns
update is performed at all, even if the host declaration has an "option
host-name". <br><br>Is this the correct behaviour? I can't deduce it
from the dhcpd.conf manual. If it's the case, is there any way I can
force dhcp server to update the dns records even if no fqdn is sent in
the client request?<br>
