Add update_script option to specify a custom script which is used to update the
dns. The script takes 2 arguments:
first is the domain to be updated
second is the actual ip address
here is an example script which use nsupdate to update bind directly:
#!/bin/sh
domain=`echo "$1" | sed s/\\\\.\\\\?$/./`
zone=`echo "$domain" | sed s/^[^.]*\\\\.//`
ip=$2
nsupdate -k /etc/ddns.key <<NSSCRIPT
zone $zone
update del $domain
update add $domain 600 IN A $ip
send
NSSCRIPT
