Question

我有一个执行以下任务的脚本：从文件中读取以获取IP地址执行Traceroute 将跳数，主机名和IP地址的结果存储到带时间戳的文件中。

问题是，结果显示重复的希望计数，当我与正常的traceroute结果进行比较时，跳数会更多。

以下是该脚本的一部分：

import socket, sys, os, ipList
from ipList import ip4
from datetime import datetime

icmp = socket.getprotobyname('icmp')
udp = socket.getprotobyname('udp')
port = 33434
max_hops = 30
ttl = 1

curr_addr = None
curr_name = None

def main(ips):
    FORMAT = '%Y%m%d%H%M'
    for ip in ips:
        path = ip+'.txt'
        new_path = 'results/%s_%s' % (datetime.now().strftime(FORMAT), path)
        dest_addr_v4 = ip
        m(dest_addr_v4, port, ttl, max_hops, new_path)

def writeFile(p, a):
#    with open(new_path, 'a') as result:
    result = open(p, 'a')
    result.write(a)
    result.close()

def create_sockets():
    recv_s = socket.socket(socket.AF_INET, socket.SOCK_RAW, icmp)    
    send_s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, udp)
    send_s.setsockopt(socket.SOL_IP, socket.IP_TTL, ttl)
    return recv_s, send_s

def m(ip, p, t, mh, path):
    while True:
      recv_s, send_s = create_sockets()
      recv_s.bind(("", p))
      send_s.sendto("", (ip, p))
      try:
          _, curr_addr = recv_s.recvfrom(512)
          curr_addr = curr_addr[0]
          try:
              curr_name = socket.gethostbyaddr(curr_addr)[0]
          except socket.error:
              curr_name = curr_addr
      except socket.error:
          pass
      finally:
          send_s.close()
          recv_s.close()
      if curr_addr is not None:
          curr_host = "%s (%s)" % (curr_name, curr_addr)
      else:
          curr_host = "*"
      r = "%d\t%s\n" % (t, curr_host)
      if t <= mh:
          writeFile(path, r)
      t += 1
      if curr_addr == ip or t > mh:
         print "Reached end of max hop or reached Destination"
         return

ipv4List = ip4()
main(ipv4List)

我有IP地址列表的文件，我正在尝试测量路径，所以理想情况下我希望结果尽可能准确。目前我得到的结果不正确，我假设是因为它正在发送多个UPD数据包并获得ICMP作为回报。

请问有什么方法可以微调这个脚本吗？

编辑：嗨，谢谢你的回复。我很抱歉忘了添加结果。

以下是我上面提到的结果：

30  router.comp-sci-staff-dhcp.hsrp.lut.ac.uk (158.125.103.1)

正如你所看到的，一切都是重复的，我怀疑是因为我将max_hop设置为30，如果增加的话，它会继续这样。如果它从我的IPlist文件的第一个条目到达目的地IP：203.175.174.10，则不显示。

我真的很感激任何形式的投入和建议。对不起，如果我的帖子不符合标准。
