Linux dhcp client not updating dns

All Linux DHCP clients (ones who get DHCP leases and one other who is configured to get fixed IP, same as XP) are not registered in DNSwhere do I start looking?

configuration files: DHCPD.conf## dhcpd.conf## general option##ddns-update-style ad-hoc;ddns-update-style interim;ddns-updates on;ddns-domainname "localdomain.local";option ntp-servers 192.168xx;allow unknown-clients;default-lease-time 86400;max-lease-time 172800;## reservetionhost xp host Linux ###option domain-name "localdomain.local";option domain-name-servers 192.168xx;option netbios-name-servers 192.168xx;option netbios-dd-server 192.168xx;option netbios-node-type 8;#subnet 192.168xx netmask 255.255.255.0 named.conf//// named.conf//options ;logging ;include "/etc/named.rfc1912.zones";include "/etc/key";include "/etc/rndc.key";controls ;zone "." IN ;zone "localdomain.local" IN ;zone "xx.168.192.in-addr.arpa" IN ; OK, problem partially solved:found this article Make DHCP Auto-update the DNSXP and linux are registering the ddns.still, I have "openfiler" that will not register in ddns.

These can be added to DNS and will always be available. But, I need a pool for a set of virtual hosts that are being configured. config files, but my DHCP/DNS provides the IP addresses as the vhosts are launched or retired.

Even simpler is to use fixed IP addresses for the virtual machines.

The name may or may not be qualified with the local domain name (it is preferable to use the domain-name option to specify the domain name). This option is only honored by dhclient-script(8) if the hostname for the client machine is not set.

So I've searched and searched....from one side of the net to the other and I can't seem to find a solution to my problem.

Check the man page on the DHCP server and read up on "DYNAMIC DNS UPDATES". And i can see hostname has been set in DHCP Server.

But i cannot ping my embedded device with that hostname.
