python中的端口掃描

Question

我是一名新的Python學習者。任何人都可以使用基本腳本來掃描http和https端口，並在用戶輸入子網（例如192.168.1.0/24）後返回IP地址嗎？感謝您的幫助

Answer 1

後來，我用Python寫了一個TCP端口掃描器。它很好地工作，並且易於配置。您輸入IP或互聯網地址，並輸出您掃描的端口。它在Python 2.7的50行中。玩的開心！

print(">> Scanning Started At %s...\n" % (time.strftime("%H:%M:%S"))) 
start_time = datetime.now() 

for port in range(min_port, max_port): 
    try: 
     response = scan_host(host, port) 
     if response == 0: 
      print(">> Port %d: Open" % (port)) 
    except Exception, e: 
     pass 

stop_time = datetime.now() 
total_time_duration = stop_time - start_time 
print("\n>> Scanning Finsihed At %s ..." % (time.strftime("%H:%M:%S"))) 
print(">> Scanning Duration: %s ..." % (total_time_duration)) 
print(">> Have a nice day!")
