利用TCP連接創建一個socket掃描port

上代碼：

#TCP
import socket
from threading import Thread
def get_port(open_port,host,ports):
    while True:
        if ports:
            port = ports.pop(0)
            c = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
            c.settimeout(0.5)
            try:
                c.connect((host,port))
            
 
except socket.timeout as e:
                print(‘[-]%d‘ % port)
                del c
            else:
                print(‘[+]%d‘ % port)
                c.send(‘1‘.encode())
                portocol = c.recv(1024).decode()
                open_port[port] = portocol
                c.close()
                
 
del c 
        else:
            break
def main():
    host = "192.168.1.33"
    open_port = {}
    ports = list(range(1,65535))
    t_list = []
    for var in range(100):
        t_list.append(Thread(target=get_port,args=(open_port,host,ports,)))
    for t in t_list:
        t.start()
    for t in t_list:
        t.join()
        
    get_port(open_port,host,ports)
    
 
print(open_port)
if __name__ == ‘__main__‘:
    main()
