Server should check whether a port is available only in case it itself isn't already listening on that port.
If `set_static_ip` is `true`, Server attempts to set a static IP for the network interface chosen by `dns.ip` setting. If the operation is successful, `static_ip.static` setting will be `yes`. If it fails, `static_ip.static` setting will be set to `error` and `static_ip.error` will contain the error message.
