I want to check the port state. I know there are plenty Portscanner implementations out there but most of them only assume that a port is open if no error was thrown, otherwise not.
func GetPortState(network string, address string, timeoutInMilliseconds int) {
timeout := time.Duration(timeoutInMilliseconds) * time.Millisecond
connection, connectionError := net.DialTimeout(network, address, timeout)
if connectionError != nil {
// inspect error
// return state ...
}
defer func() {
connectionCloseError := connection.Close()
if connectionCloseError != nil {
// return error
}
}()
// return state
}
would someone mind helping implementing the function so it’s working correctly?
Thanks in advance
