我在GitHub中看到了scapy ipsec.py python代码：如何安装和使用它？

Question

There is a python module to generate IPSec packets using scapy in GitHub, but that file is not in its own .git extension to download.

Please find the link for the code: https://github.com/secdev/scapy/blob/master/scapy/layers/ipsec.py

How can I use that script?

Answer 1

I suppose you would need to clone the full repo:

git clone https://github.com/secdev/scapy
cd scapy

From there, you can have access to the interactive shell :

sudo ./run_scapy 
Welcome to Scapy
>>> p = IP(dst="github.com")/ICMP()
>>> r = sr1(p)
Begin emission:
.Finished to send 1 packets.

That would include all scapy features, including ipsec:

>>> sa = SecurityAssociation(ESP, spi=0xdeadbeef, crypt_algo='AES-CBC',
...                          crypt_key='sixteenbytes key')
>>> p = IP(src='1.1.1.1', dst='2.2.2.2')
>>> p /= TCP(sport=45012, dport=80)
>>> p /= Raw('testdata')
>>> p = IP(raw(p))
>>> p
