python实现批量ping

用简单的代码实现批量ping，并打印无响应的IP

from scapy.all import *
from multiprocessing import Manager
from concurrent.futures import ProcessPoolExecutor
def packet_create(s):##构造ICMP报文
    pk = IP( 
        dst=s
    )/ICMP(
        type=8
    )/data
    return pk

def packet_send(s, down_list):##发送ICMP报文
    ans = sr1(packet_create(s), timeout=8)
    if ans == None:
        down_list.append(s)


if __name__ == "__main__":
    #需要扫描的存放IP地址的文件路径
    file_path = "test.txt"
    data = "A" * 32

    with open(file_path, "r") as f:
        server_IP = f.readlines()

    pool = ProcessPoolExecutor(max_workers=60)

    manager = Manager()
    down_list = manager.list()

    for s in server_IP:
        s = s.replace("\n", "")
        pool.submit(packet_send, s, down_list)
    pool.shutdown()
    
    print('以下IP地址没有响应')
    print(down_list)

• 上图是test.txt文件的格式
