Python 2.7 + Scapy 2.3.1 -


i'm trying using scapy don't know why functions don't work:

from scapy.layers.inet import * = ether() / ip(dst='192.168.1.1') / icmp() a.show()

results in: 

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 ###[ ethernet ]###     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'

without .show() works , :

pck = ether() pck.show()

works too.

i tried other functions .show, error. why?

you need import everything, try changing import statement shown below:

$ sudo python python 2.7.6 (default, jun 22 2015, 17:58:13)  [gcc 4.8.2] on linux2 type "help", "copyright", "credits" or "license" more information. >>> scapy.all import * warning: no route found ipv6 destination :: (no default route?) >>> = ether() / ip(dst='192.168.1.1') / icmp() >>> a.show() ###[ ethernet ]###   dst       = 74:11:d5:04:1b:82   src       = 80:f6:df:59:3d:35   type      = 0x800 ###[ ip ]###      version   = 4      ihl       = none      tos       = 0x0      len       = none      id        = 1      flags     =       frag      = 0      ttl       = 64      proto     = icmp      chksum    = none      src       = 192.168.0.5      dst       = 192.168.1.1      \options   \ ###[ icmp ]###         type      = echo-request         code      = 0         chksum    = none         id        = 0x0         seq       = 0x0 >>>
