I'd guess the long number is a MAC address from the
look of it. I can't help you with it, but that is what the number looks
like to me.
I'd be curious to know how this ends up, so please
keep the list posted. In the end, I'd like to benefit from your
experiences and set it up for myself. I don't need it, so I'm not in a
rush to have it working, but I'd like to have it, so why not...
Kev.

Subject: (clug-talk) BIND & dynamic
DNS with DHCP
Trying to get DDNS working. Some problems fixed and some new
problems.
So far I have found that dhcpd version 3 is needed for DDNS
and becase of a bug in Bind 9.2.0 I also needed Bind 9.2.1, maybe not but I
upgraded anyway. Also the dhcp clients must send their host names for this to
work and they don't by default so for now I am doing this by hand but I need
find a way to make the network scripts on the clinets send their host names
when the network is started. For now I am using the -h option for dhcpcd.
New problem. On my DNS I have a master zone Ept. When a client
requests an IP the dhcpd server detects the hostname correctly and using my
configuration setting for "Dynamic DNS domain name" it correctly assigns it to
the Ept domain. The dhcpd makes a call to res_nupdate in the shared library
for bind. The bind library reports that some big long number is not a zone. As
you see from the /var/log/message file
Nov 14 15:46:24 grethor dhcpd:
if IN A SlimBox.Ept domain doesn't exist add 43200 IN A SlimBox.Ept
192.168.0.108 add 43200 IN TXT SlimBox.Ept
"314fa6f54bd46778472ffc9d954897d3c9": not a zone.
I don't know what
this number is but each client gets a different number and they always get the
same number. It is to big to be an md5sum, I think. But it could be like an
md5sum because in the documentation for dhcpd it talks about using md5sum to
generate names for hosts that the names are not sent to the server using
dhcpcd -h <hostname>
Help! Has anyone used Linux to do DDNS? The
abiliy to do DDNS in realtime using the dhcpd server seems to be a new thing.
There are many simple hacks and scripts to setup DDNS using cron and other
non-realtime ways but I need realtime.
