PROBLEM WHILE USING SCAPY (Permission denied)

Question

I am trying to make a simple network scanner in python3 which can scan whole devices on LAN. That’s when i heard about Scapy. However, whenever i try to run my program, it returns an error
“PermissionError: [Errno 13] Permission denied”

Here’s my code:

import scapy.all as scapy


def scan(ip):

  scapy.arping(ip)

scan("192.168.43.1")

It would help me a lot if you guys can fix this issue. Thanks for reading.

Answer 1

I beleive the method scapy.arping() opens raw socket. Try running as root user with sudo.

Answer 2

I Had the same Issue but with "[Errno 1]" , what solved it for me was to just use root permissions via sudo (and "-E" to preserve the enviroment) like:

sudo -E python myScriptName.py
