mac에서 python 라이브러리 scapy (패킷처리) 설치

참고로 스카피는 패킷 조작 프로유틸 프로그램이다

( Scapy is a powerful interactive packet manipulation program.  )

아래 소스를 예) scapy.sh 와 같이 만든 후 실행 권한 준 이후 ( chmod +x scapy.sh ) 실행하면 자동 빌드 된다.

#!/bin/bash
 
echo "We need root permissions to install libdnet"
sudo echo "OK"
curl -O "https://bootstrap.pypa.io/get-pip.py"
python get-pip.py --user
PIP_BIN=$HOME/Library/Python/2.7/bin/pip
$PIP_BIN install scapy --user
$PIP_BIN install pypcap --user
curl -L https://github.com/dugsong/libdnet/archive/libdnet-1.12.zip -o libdnet-1.12.zip
unzip libdnet-1.12.zip
cd libdnet-libdnet-1.12
./configure
make
sudo make install
cd python
python setup.py install --user
