Ping-Check is a feature that controls the update of your new dyn-ip. # # Just use it if you know what it does! # # If you want a safety net for your home server enable Ping-Check. # # BE CAREFUL about your settings! # # You MUST NOT choose an update interval that is too short (interval < 5min) # # You MUST NOT use an internal DNS server with your dyn-hostname as a record. # # This record is most likely to send an internal IP for this hostname. Make # # sure you get a DNS result from an external server, with the correct IP. # # How does it work? # # Ping-Check compares the IP it gets back from the ping. The ping is of # # course done against the dyn-hostname. If the IP is not the same as on # # record an other update is forced. # # # # (I) if you want your router to be supported, # # *) send us a patch of your changes (plus the version number of bddc on # # which the patch works on.) # # OR # # *) send us your own parsing string and # # *) the value of the ip when offline (maybe other possible errors) # # as we do in the script and put it on the feature request forum on #
