如何在python中为traceroute获取特定跃点的IP [英] How can I get IP of a specific hop for traceroute in python

问题描述

addr = socket.gethostbyname('dalitstan.org')
target = [addr]
result, unans = traceroute(target,maxttl=32)

我正在执行此操作，并获得以下输出.这里是否有某种方法可以获取变量中特定跃点的IP.以及为什么在traceroute结果中缺少某些跳数?

I am doing this and getting the below output. Is there some way here to get the IP of specific hop in a variable. And also why some hop number are missing in the traceroute result?

Begin emission:
Finished to send 32 packets.

在尝试result.get_trace()['185.53.178.6'][7]时，我遇到了以下错误.可能是什么问题.

On trying result.get_trace()['185.53.178.6'][7] I am getting below error. What may be the issue.

Traceback (most recent call last):

    print result.get_trace()['185.53.178.6'][7]

推荐答案

您可以使用result.get_trace()提取跃点的值. 因此，对于跃点7，请使用result.get_trace()['185.53.178.6'] [7]

You can extract the value for a hop using result.get_trace() So for hop 7 use result.get_trace()['185.53.178.6'][7]

    >>> result.get_trace()['185.53.178.6'][7]
    ('203.50.6.93', False)

    or 

    >>> result.get_trace()['185.53.178.6'][7][0]
    '203.50.6.93'
    >>> something = result.get_trace()['185.53.178.6'][7][0]
    >>> something
    '203.50.6.93'

从另一条迹线进行的一些索引检查显示为

Some index checking from a different trace shown as.

    >>> result.get_trace()['161.0.97.141'].keys()
    dict_keys([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17, 18, 19, 20])

    ^^^^ missing hop 13 ^^^^ (Same as your hop 7)


    >>> for item in result.get_trace()['161.0.97.141'].keys():
    >>> print('Row number ' + str(item) + ' hop IP is : ' + result.get_trace()['161.0.97.141'][item][0])

    Row number 1 hop IP is : 10.0.0.138
    Row number 2 hop IP is : 10.218.192.1
    Row number 3 hop IP is : 58.160.250.129
    Row number 4 hop IP is : 203.50.44.36
    Row number 5 hop IP is : 203.50.11.136
    Row number 6 hop IP is : 203.50.11.180
    Row number 7 hop IP is : 203.50.6.93
    Row number 8 hop IP is : 203.50.13.98
    Row number 9 hop IP is : 202.84.222.62
    Row number 10 hop IP is : 202.84.136.209
    Row number 11 hop IP is : 202.84.253.86
    Row number 12 hop IP is : 134.159.61.46
    <<<  no hop 13 shown >>>
    Row number 14 hop IP is : 4.59.90.110
    Row number 15 hop IP is : 63.245.106.96
    Row number 16 hop IP is : 63.245.5.100
    Row number 17 hop IP is : 63.245.79.85
    Row number 18 hop IP is : 190.242.166.37
    Row number 19 hop IP is : 190.112.224.132
    Row number 20 hop IP is : 161.0.97.141
