Class Method Details
.create_listeners(address, port, logger = nil) ⇒ Object
Creates TCP server sockets bound to address
:port
and returns them.
It will create IPV4 and IPV6 sockets on all interfaces.
NOTE: We need to monkey patch this method because create_listeners on Windows with Ruby > 2.0.0 does not raise an error if we’re already listening on a port.
