- # sample script for sending user defined updates
- # 2014-2015 Christian Schoenebeck <christian dot schoenebeck at gmail dot com>
- #
- # activated inside /etc/config/ddns by setting
- #
- # option update_script '/usr/lib/ddns/update_sample.sh'
- #
- # the script is parsed (not executed) inside send_update() function
- # of /usr/lib/ddns/dynamic_dns_functions.sh
- # so you can use all available functions and global variables inside this script
- # already defined in dynamic_dns_updater.sh and dynamic_dns_functions.sh
- #
- # It make sence to define the update url ONLY inside this script
- # because it's anyway unique to the update script
- # otherwise it should work with the default scripts
- #
- # the code here is the copy of the default used inside send_update()
- #
- # tested with spdns.de
- local __URL="http://[USERNAME]:[PASSWORD]@update.spdns.de/nic/update?hostname=[DOMAIN]&myip=[IP]"
- # inside url we need domain, username and password
- [ -z "$domain" ] && write_log 14 "Service section not configured correctly! Missing 'domain'"
- [ -z "$username" ] && write_log 14 "Service section not configured correctly! Missing 'username'"
- [ -z "$password" ] && write_log 14 "Service section not configured correctly! Missing 'password'"
-
- # do replaces in URL
- __URL=$(echo $__URL | sed -e "s#\[USERNAME\]#$URL_USER#g" -e "s#\[PASSWORD\]#$URL_PASS#g" \
- -e "s#\[PARAMENC\]#$URL_PENC#g" -e "s#\[PARAMOPT\]#$param_opt#g" \
- -e "s#\[DOMAIN\]#$domain#g" -e "s#\[IP\]#$__IP#g")
- [ $use_https -ne 0 ] && __URL=$(echo $__URL | sed -e 's#^http:#https:#')
-
- do_transfer "$__URL" || return 1
-
- write_log 7 "DDNS Provider answered:\n$(cat $DATFILE)"
-
- # analyse provider answers
- # "good [IP_ADR]" = successful
- # "nochg [IP_ADR]" = no change but OK
- grep -i -E "good|nochg" $DATFILE >/dev/null 2>&1
- return $? # "0" if "good" or "nochg" found
