Function rpc_server_socket

less_slow.cpp:6711–6730

* @brief Opens the socket and binds it to the specified address and port. * @param port The port to bind to. * @param address The address to bind to. If "0.0.0.0" for IPv4 (or "::" for IPv6), * we bind to all interfaces, meaning we can receive packets from any network * interface. Binding to "127.0.0.1" (or "::1" for IPv6) will only allow * packets from the lo

 *          packets from the loopback interface, which can be handy for testing.
