A dyndns-compatible client for dynamic IPv6 addresses

ddnsclient listens via netlink for changes in the IPv6 address and performs a request to a dyndns-compatible server for every address which is not filtered out in the function filter_ip()

Usage:

ddnsclient  
  -d    -- Start in daemon-mode (logs into /var/log/ddnsclient)  
  -v    -- verbose output  

Dependencies:

• openssl
• Linux (for netstat)

Known issues / TODO:

• Make config for upstart etc
• Reduce non-verbose logging (and log to syslog?)
• Daemon-mode does not yet support pid-files
