Unless you've already found what you were looking for, I just found this on
DYNDNS.org site:
ftp://burry.dyndns.org/pub/ddclient/ddclient.tar.gz
The following may be what you need which is only a portion of the script:
---------------------------------------------------_____________
USING DDCLIENT WITH dhcpcd-1.3.17
If you are using dhcpcd-1.3.17 or thereabouts, you can easily update
your DynDNS entry automatically every time your lease is obtained
or renewed by creating an executable file named:
/etc/dhcpc/dhcpcd-{your-interface}.exe
In my case, it is named dhcpcd-eth0.exe and contains the lines:
#!/bin/sh
logger -t dhcpcd IP address changed to $1
/root/bin/ddclient -proxy fasthttp.sympatico.ca -wildcard -ip $1 | logger -t
ddclient
exit 0
Other DHCP clients may have another method of calling out to programs
for updating DNS entries.
