내 Linux OS를 업그레이드하기 전에는 python2.7의 scapy의 스니핑 기능이 제대로 작동했습니다.
from scapy.all import *
client_mac="c4:3d:c7:8f:03:19"
wlan_mac="00:c0:ca:6d:ac:fa"
sniff(iface="mon0",prn=packet_callback,filter="(ether dst "+client_mac+" and ether src "+wlan_mac+") or (ether src "+client_mac+" and ether dst "+wlan_mac+")")
업그레이드 후 python2.7에서 스크립트를 다시 실행했고 scapy로부터 다음 메시지를 받았습니다.
WARNING: No route found for IPv6 destination :: (no default route?)
tcpdump: WARNING: eth0: no IPv4 address assigned
올바른 인터페이스를 스니핑하려면 어떻게 해야 합니까?
위에서 스니핑 기능을 추가해 보았지만 conf.iface="mon0"여전히 성공하지 못했습니다.
ifconfig -a사용
