的Python 2.7 + Scapy的2.3.1

我試圖使用scapy，但我不知道爲什麼有些功能不起作用：的Python 2.7 + Scapy的2.3.1

Traceback (most recent call last): 
    File "/home/user/PycharmProjects/untitled/main.py", line 7, in <module> 
    a.show() 
    File "/usr/lib/python2.7/dist-packages/scapy/packet.py", line 819, in show

    reprval = f.i2repr(self,fvalue) 
    File "/usr/lib/python2.7/dist-packages/scapy/fields.py", line 191, in i2repr 
    x = self.i2h(pkt, x) 
    File "/usr/lib/python2.7/dist-packages/scapy/layers/l2.py", line 88, in i2h 
    x = conf.neighbor.resolve(pkt,pkt.payload) 
    File "/usr/lib/python2.7/dist-packages/scapy/layers/l2.py", line 38, in resolve 
    return self.resolvers[k](l2inst,l3inst) 
    File "/usr/lib/python2.7/dist-packages/scapy/layers/inet.py", line 727, in <lambda> 
    conf.neighbor.register_l3(Ether, IP, lambda l2,l3: getmacbyip(l3.dst)) 
    File "/usr/lib/python2.7/dist-packages/scapy/layers/l2.py", line 56, in getmacbyip 
    iff,a,gw = conf.route.route(ip) 
AttributeError: 'NoneType' object has no attribute 'route'

沒有.show()：在

from scapy.layers.inet import * 
a = Ether()/IP(dst='192.168.1.1')/ICMP() 
a.show()

結果它的作品和：

pck = Ether() 
pck.show()

也可以。

我嘗試了一些其他功能，如.show，但有時我得到這個錯誤。爲什麼？

我認爲你錯過了一個步驟，你的第一行指定了如何構造一些數據包，show試圖解析接收到的數據包。

嘗試類似：

from scapy.layers.inet import * 
a = Ether()/IP(dst='192.168.1.1')/ICMP() # Rule for creating packets 
s,r = sr1(a) # Send & Receive one packet(s) 
r.show() # Show the recieved packet(s)

這使用您的規則來構建單個數據包，把它和捕捉回覆/答覆，然後顯示實際數據包。

它使回溯（最近通話最後一個）：文件「/home/inck/PycharmProjects/untitled/main.py」，7號線，在 S，R = SR1（一）＃發送＆接收一個數據包文件「/usr/lib/python2.7/dist-packages/scapy/sendrecv.py」，行334，sr1 s = conf.L3socket（filter = filter，nofilter = nofilter，iface = iface）文件「/usr/lib/python2.7/dist-packages/scapy/arch/linux.py」，行307，在__init__中 self.ins = socket.socket（socket.AF_PACKET，socket.SOCK_RAW， socket.htons（type）） [...] socket.error：[Errno 1]不允許操作 – Chris

您需要超級用戶（root）權限，因爲它會創建套接字。只要sudo，你就要走了。 – Misko

您需要導入的一切，那麼請嘗試更改導入語句如下所示：

據Scapy的努力成爲智能地在鏈路層中有效默認填充。當你不導入整個模塊時，它不能很好地處理事物。

如果您稍微更改一下代碼，以便它不需要執行該檢查，就會生成您的數據包。

from scapy.layers.inet import * 
a = Ether(src='AA:AA:AA:AA:AA:AA', dst='BB:BB:BB:BB:BB:BB')/IP(src='192.168.1.1')/ICMP() 
a.show()
