带有小包的数据包发送

Question

I tried to send icmp packet with scapy without success, to understand where and what is the problem. I wrote some code in python that sends icmp packet. Of course the code is running successfully without any problem. also in scapy the problem is present, My internal ip is 10.0.0.8 in 10.0.0.0/24 network the code with error in scapy for example is :

• send(IP(dst="10.0.0.138")/ICMP())
• send(IP(dst="8.8.8.8")/ICMP())

the error message is:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:\Python26\lib\site-packages\scapy\sendrecv.py", line 251, in send
    __gen_send(conf.L3socket(*args, **kargs), x, inter=inter, loop=loop, count=count,verbose=verbose, realtime=realtime)
  File "C:\Python26\lib\site-packages\scapy\sendrecv.py", line 234, in __gen_send
    s.send(p)
  File "C:\Python26\lib\site-packages\scapy\arch\pcapdnet.py", line 237, in send
    ifs = dnet.eth(iff)
  File "dnet.pyx", line 112, in dnet.eth.__init__
OSError: Result too large

Note: when I try to run:

send(IP(dst="10.0.0.8")/ICMP())

or

send(IP(dst="127.0.0.1")/ICMP())

the packet is sent successfully!
