scapy:发送数据包时出错 [英] scapy: error sending packets

问题描述

我是 scapy 的新手，我正在学习一些在线教程，但我遇到了这个问题.我能够通过有线连接发送数据包，但是当我尝试使用无线连接时，我遇到了这个错误.我尝试搜索谷歌，但没有帮助.我希望找到解决办法.提前致谢.

我使用的是 windows 8.1，python 2.7

<预><代码>>>>p=IP(dst="192.168.1.1")/ICMP()>>>sr1(p)开始发射:错误:---发送数据包时出错回溯(最近一次调用最后一次):文件c:\Python27\lib\site-packages\scapy\arch\windows\__init__.py"，第 374 行，在 sndrcv 中pks.send(p)文件c:\Python27\lib\site-packages\scapy\arch\pcapdnet.py"，第 257 行，发送sx = str(cls()/x)文件c:\Python27\lib\site-packages\scapy\packet.py"，第 268 行，在 __str__ 中返回 self.build()文件c:\Python27\lib\site-packages\scapy\packet.py"，第 330 行，在构建中p = self.do_build()文件c:\Python27\lib\site-packages\scapy\packet.py"，第 319 行，在 do_buildpkt = self.self_build()文件c:\Python27\lib\site-packages\scapy\packet.py"，第 310 行，在 self_buildp = f.addfield(self, p, val)文件c:\Python27\lib\site-packages\scapy\fields.py"，第 70 行，在 addfield返回 s+struct.pack(self.fmt, self.i2m(pkt,val))文件c:\Python27\lib\site-packages\scapy\layers\l2.py"，第 95 行，在 i2m 中返回 MACField.i2m(self, pkt, self.i2h(pkt, x))文件c:\Python27\lib\site-packages\scapy\layers\l2.py"，第 89 行，在 i2h 中x = conf.neighbor.resolve(pkt,pkt.payload)文件c:\Python27\lib\site-packages\scapy\layers\l2.py"，第38行，解析返回 self.resolvers[k](l2inst,l3inst)文件c:\Python27\lib\site-packages\scapy\layers\inet.py"，第 732 行，在 <lambd＞conf.neighbor.register_l3(Ether, IP, lambda l2,l3: getmacbyip(l3.dst))文件c:\Python27\lib\site-packages\scapy\arch\windows\__init__.py"，第 292 行，在 getmacbyipifip = str(pcapdnet.dnet.intf().get(iff)['addr'])密钥错误:'地址'信息: --- 发送数据包时出错......................................收到 25 个数据包，得到 0 个回答，剩余 1 个数据包警告:__del__:不知道如何关闭文件描述符.前面有错误！恳求se 报告此错误.

解决方案

有点晚了，但是:

几个月前我遇到了同样的问题，最终对我有用的是通过另一个网络接口隧道连接 WiFi.看来问题出在IP获取过程中；也许您应该尝试以管理员身份运行，并设置 Python 和 Scapy 文件的功能，以便它们具有完全控制权(右键单击->属性->安全性).

您在使用 send/sr/srp 等其他方法时是否遇到同样的问题?

I am new to scapy and I am following some online tutorial, but I am stuck at this problem. I am able to send packets through a wired connection but when I try this with wireless, I face this error. I tried searching google but it was of no help. I hope to find a solution. Thanks in advance.

I am using windows 8.1, python 2.7

解决方案

Slightly late, but:

I ran into the same problem a few months ago, and what worked for me eventually was to tunnel the WiFi through another network interface. It seems that the problem is in the IP obtaining process; Maybe you should try to run as administrator, and set the features of both Python and the Scapy files so that they have full control (right click->Properties->Security).

Do you encounter the same problem while using other methods like send/sr/srp?
