[gentoo-user] DDNS Problem

[Hiren Dave]

Hi All,
I am facing problems in configuring DDNS with dhcpd. When i'm rebooting linux machine, it is getting dynamically ip address from linux server but no dynamic dns updates are there. Also when i renew ip address of windows 2000 prof, it not getting ip address from linux dhcp server. Following is the configuration that might help you solving my problem. Both Master DNS and dhcp server are on the same server

I am facing problems in configuring DDNS with dhcpd. When i'm rebooting 
linux machine, it is getting dynamically ip address from linux server 
but no dynamic dns updates are there. Also when i renew ip address of 
windows 2000 prof, it not getting ip address from linux dhcp server. 


You should explicitly allow updates in named.conf and
make some directories and zone files writable by bind.
Read relevant parts of BIND Administrator Reference Manual.
You may also want to add more logging options to named.conf
and there should be enough info in syslogs to troubleshoot
the problem you're having.

I think you must allow dynamic updates by allow-update or update-policy
in bind's zone-files...

And one more thing: for every ip from your dyn-ip pool I would
set very short ttl/expire in your zone-files. Otherwise caching-clients
would get know too late, that there was a change in ip/dn assignment...

Hi,

 I think you must allow dynamic updates by allow-update or update-policy in bind's zone-files...
Here is my named.conf file which may help you solving my problem

named.conf on server1.guru.com
