在 Scapy 参数中分配的值
Values assigned in the Scapy parameters
如何找出 IP 协议或任何其他协议中的任何参数中分配给特定值的数字？
如果我设置一个值：
a=IP(proto=73)
我得到：
version= 4
ihl= None
tos= 0x0
len= None
id= 1
flags=
frag= 0
ttl= 64
**proto= rspf**
chksum= None
src= 127.0.0.1
dst= 127.0.0.1
\options\
如果我设置另一个值：
a=IP(proto=12)
我得到：
version= 4
ihl= None
tos= 0x0
len= None
id= 1
flags=
frag= 0
ttl= 64
proto= pup
chksum= None
src= 127.0.0.1
dst= 127.0.0.1
\options\
等等。
一些数字被分配给包的一些参数中的一个值。目前，我正在列出从 1 到 100 的每个数字，以查看其中隐藏的内容，但这是一个非常漫长和痛苦的过程。
如何查看分配给值的数字？
谢谢。
