# BashDynDnsChecker (bddc) #
# #
# This is a dyndns check and synchronizing script #
# the executables it needs are: #
# grep, egrep, expr, curl, echo, sed, ifconfig, date, tail, uniq, cut, cat, #
# ping, rm and wget or curl. #
# which should be available in every *nix system. #
# #
# copyright 2006 - 2009 by florian klien #
# florian[at]klien[dot]cx #
# #
# supports ip reception from ifconfig, an external url (by http) #
# and parsing from a router. #
# #
# supports dyndns synchronization with afraid.org, dyndns.org and no-ip.com #
# #
# (!) it needs to be called in crontab as a cronjob, or any other similar #
# perpetual program. #
# #
# (!) if you use bddc on a wrt environment, change the very first line from #
# '#/bin/bash' to '#/bin/sh', without the quotes #
# and clear the cutting_string variable at the end of the edit space #
# you should further turn the log level very low, after you made sure bddc #
# works correctly. this would otherwise fill up your memory quickly. #
# #
# (!) 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 #
# sourceforge.net. #
# *) plus full name of the router #
# *) your name and email address for contact and testing purpose before #
# a release is done. #
# OR #
# add the following information to the feature request site on #
# sourceforge.net: #
# *) the url under which the external ip can be read from your router #
# *) a copy of the html source code from this site (each online and offline) #
# *) the complete name of your router #
# *) the url to call for logout of the router #
# *) your name and email address for contact and testing purpose before #
# a release is done. #
# #
# exit codes: #
# 0 -> everything went fine #
# 1 -> some error occured during runtime #
# 2 -> some config error was caught #
# 11 -> ip address was private #
# 28 -> timeout at connecting to some host #
