'Python3 - installing Scapy in OS
I installed the networking module Scapy.
When I import scapy (import scapy) everything works fine. When I import all from scapy (from scapy.all import *), it brings up this error:
Traceback (most recent call last):
File "/Users/***/Downloads/test.py", line 5, in <module>

raise OSError("Cannot find libdnet.so")
OSError: Cannot find libdnet.so
I found out on another post that we might have to download additionnal modules in order to make scapy fully work. What should be done exactly? I tried using (port ** install) which didn't work because port is not supported anymore? If you have any idea how to make it work in python3, I will be active. Here is more additionnal informations:
python 3.4.3
mac os 10.10.4
scapy-python3==0.14
EDIT: Another interesting thing is :
On all OS except Linux libpcap should be installed for sending and receiving packets (not python modules - just C libraries). libdnet is recommended for sending packets, without libdnet packets will be sent by libpcap, which is limited. Also, netifaces module can be used for alternative and possibly cleaner way to determine local addresses. Source: https://pypi.python.org/pypi/scapy-python3/0.11
Dnet seems to only work with version 2.7 : https://pypi.python.org/pypi/dnet/1.12
Solution 1:[1]
Up-to-date edit: this issue has been fixed on recent versions of scapy, simply update your scapy version using pip install scapy>=2.4.0
You have to install libdnet. Not the python library (which does not work on python3 as you mentioned), but the library itself. There has to be library file libdnet.so somewhere in your system where python searches for libraries. Downloading the libdnet source and compiling should make it work:
wget http://libdnet.googlecode.com/files/libdnet-1.12.tgz
tar xfz libdnet-1.12.tgz
cd libdnet-1.12
./configure
make
Also, there is a possibility to use libpcap for sending packets and not to use libdnet, but I recommend trying to make libdnet work first.

You can now install this easily with Homebrew by using the command:
brew install libdnet
after you've installed Homebrew.
Solution 3:[3]
You can try the following:
git clone https://github.com/secdev/scapy
cd scapy
./run_scapy
