Python + Scapy on FreeBSD

This is the complete explanation from the FreeBSD forum: Solved – [Python3.7 + Scapy] Class from Scapy is not found | The FreeBSD Forums

I started with installing FreeBSD 12.2 on a VirtualBox VM, set it up as a router (with IP Forwarding = 1 and ipfw firewall) with several ports needed (squid proxy and mpd for vpn). I’m going to use this router for my Cybersecurity class.

To help me teaching Cybersecurity, I need Python and Scapy module to do sniffing and spoofing. And this post is how I install Python and Scapy on FreeBSD 12.2.

Step 1. Install Python3.7. Okay, it’s true Python3.8 is recommended, however I still unable to install Scapy over Python3.8, since every time I try to install Scapy, it automatically assign itself to Python3.7.

# cd /usr/ports/lang/python37
# make install clean

Step 2. Install “pip” as Python Package. Previously I installed Scapy using its port (/usr/ports/net/scapy), however it didn’t work. It gave me an error message, saying:

$ python3.7
Python 3.7.9 (default, Apr 26 2021, 05:45:03)
[Clang 10.0.1 ([email]git@github.com[/email]:llvm/llvm-project.git llvmorg-10.0.1-0-gef32c611a on freebsd12
Type "help", "copyright", "credits" or "license" for more information.
>>> from scapy.all import *
>>> a=IP()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'IP' is not defined

So, based on my previous failure, I installed “pip” (Package Installer for Python), just like the Scapy documentation recommend:

# cd /usr/ports/devel/py-pip
# make install clean

Step 3. Install Scapy using “pip”

# pip install --pre scapy

Now I can use Scapy inside Python3.7

# cd /usr/ports/devel/py-pip
# make install clean
# pip install --pre scapy
$ python3.7
Python 3.7.9 (default, May  6 2021, 04:34:40)
