The DHCP server there- fore does not attempt to set up an A record for the client, but does set up a PTR record for the IP address that it assigns the client, pointing at jschmoe.

Once the DHCP client has an IP address, it can update its own A record, assuming that the "radish.org" DNS server will allow it to do so.

If the server is configured not to allow client updates, or if the client doesn't want to do its own update, the server will simply choose a name for the client from either the fqdn option (if present) or the hostname option (if present).

i take it that during handshake, the laptop will send its hostname (i don't know what that will be for win XP and win7 dhcp clients, but i presume it will send the output of command 'hostname' for linux clients - or at least thats what i would like it to send....)"nass-notebook" Then the server will append "" and it will update the DNS with an entry looking like "nass-notebook." corresponding to some ip address... for example my dhcpd.leases file contains these entries: the 1st (192.168.0.109) is definitely a fedora laptop.. it seems that since the dhcp server can get "nasslaptop" to work as i have in mind... it also feels that differences in dhcp client configurations causes all this fuss (? is it possible to just get the server to arrange fqdn's for the clients, by just getting the hostname out of the clients and doing the rest of the work , server-side?? i have attached my for your reference: authoritative; server-name "stardust.nebula.org"; option domain-name "nebula.org"; option domain-name-servers 192.168.0.19, 192.168.0.6; option routers 192.168.0.19; option netbios-name-servers 192.168.0.6; #WINS option netbios-dd-server 192.168.0.6; #SMB option netbios-scope ""; option netbios-node-type 8; default-lease-time 21600; max-lease-time 43200; include "/etc/rndc.key"; ddns-update-style interim; ddns-domainname "nebula.org"; ddns-hostname = pick(option fqdn.fqdn,option fqdn.hostname,option host-name,concat ("dhcp-",binary-to-ascii(10, 8, "-", leased-address))); allow client-updates; zone subnet 192.168.0.0 netmask 255.255.255.0 groupdhcp and bind are separate animals.

and as i see it has got a client-hostname entry as "fedorahost.";... i mean the hostname of the fedora laptop is "fedorahost".... dhcp is for assigning dynamic ip addresses bind is for binding domain names to static ip addresses.
