-h
,
--help
Shows the help message provided by the program and exit.
The following commands are understood:
[--force] HOSTNAME
Perform an update for a single host, specified by the given hostname.
When calling an update, the DDNS client automatically checks if this update is required by testing whether the hostname points to the current public IP address. Therefore it is not guaranteed than an update is performed.
The --force switch can be used to skip that
check and perform an update. Please note that some providers
may block your account if unnecessary updates are repeatedly
performed.
[--force]
Update all configured dynamic DNS hosts when an update is necessary.
The --force switch has the same effect as
with the update command.
Guesses the public IPv6 and IPv4 addresses with help of an external server and prints them on the conole.
This command will print out a list of all supported dynamic DNS providers.
