Question

在VMWare Fusion上使用Scapy with Linux X 10.11.1会导致Linux客户机锁定。

以下示例代码重现了此问题;

from scapy.all import *
pkt = IP(dst="8.8.8.8")/UDP(dport=53)/DNS(rd=1,qd=DNSQR(qname="iops.io"))
answer = sr1(pkt,verbose=1)

附加strace显示以下内容，然后立即死亡;

根据docs，PACKET_ADD_MEMBERSHIP用于配置混杂模式。

Answer 1

这是由于VMWare Fusion中的promisc限制，请参见主题here。

作为临时解决方法，您可以在“首选项＆gt;网络”中取消选中“要求身份验证以进入混杂模式”框，但只有在您信任每个来宾虚拟机时才应使用。
