If the attack effect is not obvious, it may be that the target machine does not open the filled TCP port or the firewall denies access to the port. At this time, you can select the TCP port that is allowed to access. Generally, Windows systems open ports tcp139 and UNIX systems open ports tcp7, 21, 23, etc.? ?
