Hello I added small feature to ddns-script form myself, but it might be useful for others. This enhancement allow user to specify any script to obtain IP address. In configuration file option "ip_source" should be set to "script" and option "ip_script" should contain path to user script. Script must just return IP address.
I use this to obtain address from status page generated by my modem (and wait a little time if connection isn't established). I attach file with differences in the dynamic_dns_functions.sh file (and also proposed additions to configuration file). I hope i do it right (i don't have any experience with that :)). I edited this files right on my router. What do you think about this idea?
