篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了python中的TCP Traceroute相关的知识，希望对你有一定的参考价值。
我正在编写一个python脚本来执行'TCP Traceroute'。我知道scapy是一个很有用的库，但是我没有得到我需要的结果。谁能帮我解决这个问题？我希望python脚本生成与命令行类似的结果。
我使用linux，python 2.7和scapy 2.4。我不确定为什么所有跳跃显示相同的IP地址。
from scapy.layers.inet import traceroute
result, unans = traceroute('172.217.17.46', maxttl=30)
for snd, rcv in result:
print snd.ttl, rcv.src, snd.sent_time, rcv.time
当我运行此代码时，我得到以下结果：
1 10.0.2.2 1541113255.58 1541113255.6

我希望从命令行运行tcptraceroute时获得相同的结果：tcptraceroute 172.217.17.46

问题1：scapy traceroute功能真的是TCP traceroute吗？问题2：我是scapy和traceroute的新手，代码中是否有遗漏的东西？如果scapy不适合，我还可以使用其他库吗？我真的很感激帮助和任何指针。
注意：我想为IPV6和IPV4执行TCP跟踪路由。
答案
scapy traceroute功能真的是TCP traceroute吗？
是的它确实做TCP traceroute（除其他外）。看看Scapy source-code：
@conf.commands.register def traceroute(target, dport=80, minttl=1, maxttl=30, sport=RandShort(), l4 = None, filter=None, timeout=2, verbose=None, **kargs): """Instant TCP traceroute traceroute(target, [maxttl=30,] [dport=80,] [sport=80,] [verbose=conf.verb]) -> None""" if verbose is None: verbose = conf.verb if filter is None: # we only consider ICMP error packets and TCP packets with at # least the ACK flag set *and* either the SYN or the RST flag # set filter="(icmp and (icmp[0]=3 or icmp[0]=4 or icmp[0]=5 or icmp[0]=11 or icmp[0]=12)) or (tcp and (tcp[13] & 0x16 > 0x10))" if l4 is None: a,b = sr(IP(dst=target, id=RandShort(), ttl=(minttl,maxttl))/TCP(seq=RandInt(),sport=sport, dport=dport), timeout=timeout, filter=filter, verbose=verbose, **kargs) else: # this should always work filter="ip" a,b = sr(IP(dst=target, id=RandShort(), ttl=(minttl,maxttl))/l4, timeout=timeout, filter=filter, verbose=verbose, **kargs) a = TracerouteResult(a.res) if verbose: a.show() return a,b
I want to perform
tcp traceroute for both ipv6 and ipv4Again looking at
Scapy source code, traceroot6 can do the job:
def traceroute6(target, dport=80, minttl=1, maxttl=30, sport=RandShort(), l4 = None, timeout=2, verbose=None, **kargs): """ Instant TCP traceroute using IPv6 : traceroute6(target, [maxttl=30], [dport=80], [sport=80]) -> None """ if verbose is None: verbose = conf.verb if l4 is None: a,b = sr(IPv6(dst=target, hlim=(minttl,maxttl))/TCP(seq=RandInt(),sport=sport, dport=dport), timeout=timeout, filter="icmp6 or tcp", verbose=verbose, **kargs) else: a,b = sr(IPv6(dst=target, hlim=(minttl,maxttl))/l4, timeout=timeout, verbose=verbose, **kargs) a = TracerouteResult6(a.res) if verbose: a.display() return a,b
traceroute ipv6的示例代码：
from scapy.all import * waypoint = "2001:301:0:8002:203:47ff:fea5:3085" target = "2001:5f9:4:7:2e0:81ff:fe52:9a6b" traceroute6(waypoint, minttl=10, maxttl=40, l4=IPv6ExtHdrRouting(addresses=[target])/ICMPv6EchoRequest(data=RandString(7)))
I am not sure why same IP addresses are shown for all the hops.
通过在traceroute（）函数的l4参数中指定完整数据包来使用DNS traceroute，您不会获得所有跃点的相同IP地址。
from scapy.all import * target = ["172.217.17.46"] result, unans = traceroute(target, l4=UDP(sport=RandShort())/DNS(qd=DNSQR(qname="www.google.com")))
或者您可以使用TCP SYN traceroute获得类似的结果：
from scapy.all import * target = ["172.217.17.46"] result, unans = sr(IP(dst=target, ttl=(1, 10)) / TCP(dport=53, flags="S")) for snd, rcv in result: print(snd.ttl, rcv.src, snd.sent_time, rcv.time)
或者您可以使用IP and UDP packets创建traceroute来实现Scapy，如下所示：
from scapy.all import * hostname = "172.217.17.46" for i in range(1, 28): pkt = IP(dst=hostname, ttl=i) / UDP(dport=33434) reply = sr1(pkt, verbose=0) if reply is None: break elif reply.type == 3: print("Done!", reply.src) break else: print("%d hops away: " % i, reply.src, reply.time)
Is there any other library which I can use if
Scapy is not suitable?- 看看webb。我没有使用它，但你可以像这样使用它：
import webb webb.traceroute("www.google.com") webb.traceroute("www.google.com",'file-name.txt')
- 此外，Thomas Guettler的check out this
tcptraceroute。 - 或者这个由Addy Yeow（Ayeowch）执行的Multi-source traceroute with geolocation。
除其他外，使用
-j参数（JSON_FILE），它将列出JSON文件格式的源。 - 或克里斯蒂安克雷比奇的this implementation。它可以将traceroute信息解析为一系列跳跃对象，每个跳跃对象由一个或多个探测结果组成，同样也包括对象实例。此外，字符串格式化产生熟悉的traceroute输出。
（为了与
Python 3合作，需要将cStringIO改为from io import StringIO
没有scapy（使用Windows控制台）：
创建一个名为
output.py的脚本，其中包含以下内容：
import sys
from subprocess import Popen
if len(sys.argv) < 2:
print('Usage: output.py "command to watch"')
sys.exit(1)
cmd_line = sys.argv[1:]
p = Popen(cmd_line)
p.communicate()[0]
用法示例：python output.py ping google.com
ping的示例输出：Pinging google.com [216.58.209.14] with 32 bytes of data: Reply from 216.58.209.14: bytes=32 time=50ms TTL=56 Reply from 216.58.209.14: bytes=32 time=45ms TTL=56 Reply from 216.58.209.14: bytes=32 time=45ms TTL=56 Reply from 216.58.209.14: bytes=32 time=45ms TTL=56 Ping statistics for 216.58.209.14: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 45ms, Maximum = 50ms, Average = 46ms
用法示例：python output.py tracert google.com
tracert的示例输出：Tracing route to google.com [172.217.18.174] over a maximum of 30 hops: 1 <1 ms 1 ms 1 ms 192.168.0.1 2 6 ms 8 ms 8 ms xx.xx.xx.xx 3 8 ms 8 ms 8 ms [xx.xx.xxx.xxx] 4 17 ms 16 ms 16 ms be3549.ccr31.sof02.atlas.cogentco.com [154.54.59.138] 5 18 ms 17 ms 20 ms be3421.ccr51.beg03.atlas.cogentco.com [130.117.0.94] 6 32 ms 31 ms 30 ms be3464.ccr52.vie01.atlas.cogentco.com [154.54.59.189] 7 39 ms 37 ms 44 ms be3462.ccr22.muc03.atlas.cogentco.com [154.54.59.182] 8 42 ms 48 ms 44 ms be2960.ccr42.fra03.atlas.cogentco.com [154.54.36.253] 9 44 ms 50 ms 50 ms be3187.agr41.fra03.atlas.cogentco.com [130.117.1.117] 10 43 ms 45 ms 46 ms tata.fra03.atlas.cogentco.com [130.117.15.86] 11 45 ms 45 ms 44 ms 72.14.196.162 12 43 ms 41 ms 46 ms 108.170.251.129 13 46 ms 46 ms 45 ms 74.125.37.167 14 45 ms 52 ms 48 ms fra15s29-in-f14.1e100.net [172.217.18.174]
如果您不希望解析名称，可以使用tracert -d。

OSX and Linux and with Python 2.7 you can use this parser.
