ddns-scripts: Update to Version 2.1.0-1 see description
- fixed postinst and prerm in Makefile - implementation of provider specific update scripts into services and services_ipv6 file. first Provider "no-ip.com" - Thanks to DarkStarXxX for request and testing - finished uci/ddns wiki at http://wiki.openwrt.org/doc/uci/ddns - rewritten retry management - rewritten logging including following Issue 469 https://github.com/openwrt/packages/issues/469 - stop running sections on hotplug ifdown event (like start on ifup) - implement trap detection also kill "sleep" child processes SIGHUP to reload configuration (not really reloading, simply starting a new process) /etc/init.d/ddns reload implemented - code optimization - new provider LoopiaDNS.se Issue 494 https://github.com/openwrt/packages/issues/494 Signed-off-by: Christian Schoenebeck <christian.schoenebeck@gmail.com>
