Functions

func Listen

func Listen(name string, port string) (net.Listener, *net.TCPAddr)

Listen returns a listener for the port. Port can be a port or a bind address and a port (e.g. "8080" or "[::1]:8080"...). If the port component is 0 a free port will be returned by the system. This logs critical on error and returns nil (is meant for servers that must start).

func NormalizePort

func NormalizePort(port string) string

NormalizePort parses port and returns host:port if port is in the form of host:port already or :port if port is only a port (doesn't contain :).

func Proxy

func Proxy(port string, dest *net.TCPAddr) *net.TCPAddr

Proxy starts a tcp proxy.

func ProxyToDestination

func ProxyToDestination(listenPort string, destination string) *net.TCPAddr

ProxyToDestination opens a proxy from the listenPort (or addr:port) and forwards all traffic to destination (host:port)

func Resolve

func Resolve(host string, port string) *net.TCPAddr

Resolve returns the TCP address of the host,port suitable for net.Dial. nil in case of errors.

func ResolveDestination

func ResolveDestination(dest string) *net.TCPAddr

ResolveDestination returns the TCP address of the "host:port" suitable for net.Dial. nil in case of errors.
