I wanted to use pyshark to capture network traffic, so naturally I searched first for the most simple examples. Having found a recipe to make a daily cron job, i changed it to capture for a minute.
import pyshark
file = 'c:\\qu\\test.pcap'
output = open(file, "w")
time = 60
capture = pyshark.LiveCapture(interface="WiFi", output_file=file)
capture.sniff(timeout=time)
output.close()
of course, it didn't work! but this error message totally threw me. What does it mean?
c:\Users\userad>py shark1.py
Traceback (most recent call last):
