python - Python Scapy“NameError:未定义全局名称'LOOPBACK_NAME'”

我有一个非常简单的scapy程序，它对我的​​子网做了一个arp_ping

from scapy.all import srp, Ether, ARP, conf

def arp_ping(subnet):
    conf.verb = 1
    answered, unanswered = srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst=subnet),timeout=2,verbose=False, inter=0.1)
    return [rcv.sprintf(r"%Ether.src% - %ARP.psrc%") for snd, rcv in answered]

if __name__=="__main__":
    subnet = '192.168.1.0/24'

    for i in arp_ping(subnet):
        print i

编辑

用choco重新安装atleast PyWin32和WinPcap后，现在出现此NameError：

Traceback (most recent call last):

    from scapy.all import srp, Ether, ARP, conf

检查缺陷问题

运行scapy.bat检查是否存在缺陷，将导致以下消息：

INFO: Can't load Python libreadline or completer
INFO: Can't import matplotlib. Won't be able to plot.
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().

    return LOOPBACK_NAME
NameError: global name 'LOOPBACK_NAME' is not defined

我的猜测是：

WARNING: No match between your pcap and windows network interfaces found. You probably won't be able to send packets. Deactivating unneeded interfaces and restarting Scapy might help.Check your winpcap and powershell installation, and access rights.

是造成此问题的原因，但是我不确定如何解决此问题。

最佳答案

您使用的是旧版本，请通过以下方式进行更新
pip install scapy --upgrade获得2.4.0

我可以看到，因为最新版本不再需要libreadline

在最新版本中，您需要安装的唯一依赖项是：


Winpcap或Npcap
IPython（如果询问）
