Dns & Dhcp
Picture if you will a DNS server (BIND 9), happily answering requests about local zones, and forwarding all else on to my ISP's DNS.
The same box also runs a DHCP server daemon, which just as happily does its job of managing IP leases as systems on the local zones come and go.
Now... is is possible to arrange for the DNS's local zone tables to be updated as IP leases are assigned/renewed/expire?
yeh ... possible
yes ... what u need is dynamic dns. i guess bind 9 supports
check out the below mentioned link .
also read the micro howto at .
i hope this helps u out.
Now I just have to figure out how to get the other sysems on the LAN to send the updates to BIND.
So far, the OS/2 system's built-in nameserver update utility seems to not be formatting the request exactly as BIND expects it.
...and I haven't touched the Win98 box yet, though I'm reasonably certain that it doesn't have any built-in support for DDNS.
Have been doing some exploring, and it appears as though what I need is not for the client systems to send DDNS updates, rather the DHCP server daemon should be sending the updates.
Naturally DHCP v2 was shipped with my distro, and does not suport Dynamic DNS. :(
I now have a copy of DHCP v3... It's just a matter of figuring out how to compile & install it--something I've never done before. :study:
