updated documentation to reflect the migration to Gitea
correctly handle IPv4 or IPv6 addresses to be empty
added Remote, IPv4 and IPv6 addresses to the debug output
Implemented consistent output (normally provide an HTTP response when
usual things go wrong)
Hid detailed error information in debug info so that end users cannot
see this
new functionality:
- ability to load a config file (no more hard-coding settings) that
can be optional, required or ignored
- added RecordTTL setting (used to be hard-coded to 1h)
Fixes:
- ExpireAfter now also accepts just a number of seconds (without unit
s)
Other changes:
- AllowDebugKey now defaults to 'off'
- UpdateTXT and DeleteTXT no longer need a trailing whitespace
- sanitized perodSeconds so that it only does a single multiplication
Changed the behaviour of the update command so that it would not just
pick the remote address if no ip parameter was provided.
To autodetect the IP address it is now mandatory to pass value auto (so
ip=auto) for the ipv4addr or ipv6addr. This also allows to specify which
address should be autodetected and have a static address passed for ipv4
and have the ipv6 address autodetected for multi-network systems (also
closes#6)
