Question

我的信息包：

a=IP(src="30.1.1.2",dst="20.1.1.2",options=IPOption('\x83\x07\x04\x00\x00\x00\x00\x00'),)

我收到错误：

a=bytes(IP(src="30.1.1.2",dst="20.1.1.2",options=IPOption('\‌x83\x07\x04\x00\x00\‌x00\x00\x00'),))
Traceback (most recent call last):

由于您使用的是Python 3，因此您应该使用bytes代替str来获取IP选项：

a = bytes(IP(src="30.1.1.2", dst="20.1.1.2",
             options=IPOption(b'\x83\x07\x04\x00\x00\x00\x00\x00'))

scapy3.0.0和python3.5中的IPOptions抛出错误
