| # 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:#') |

| # "good [IP_ADR]" = successful |
