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?
