func CloseConnection

func CloseConnection(cnx io.Closer, log Logger, id string, name string)

func FerryBytes

func FerryBytes(
	client *net.TCPConn,
	server *net.TCPConn,
	cnxId string,
	maxTeardownTimeInSecs int,

FerryBytes copies bytes between two sockets. Tries to handle disconnections safely. When one socket disconnects, a CloseWrite() is done to the other socket, and a teardown timer started with the specified timeout value (if value is zero, a default value of 10 seconds is used). If a graceful disconnect from the other socket is not detected within that period, the other end is forcefully closed.

func OriginalDestination

func OriginalDestination(cnxId string, conn *net.Conn) (string, error)

OriginalDestination returns an intercepted connection's original destination. Adapted from

func RandomString

func RandomString(strlen int) string
