Rewritten Pull for #5885
When ran from the command line, the script prints
error messages like below. They are caused by supplying
empty "$password" and "$URL_PASS" for some log messages
like "130822 : Detect local IP on 'interface'".
The fix is to check if the values are not empty before running
through sed.
/etc/init.d/ddns start
sed: no previous regexp
