Currently, I have a python script set up to manage the tcpdump tool. The issue arises when attempting to terminate the tcpdump process within my python script:
import subprocess
pid = 9669 # pid of the tcpdump process
subprocess.call(["sudo", "kill", "-9", f"{pid}"])
An error is triggered displaying:
kill: (9669): Permission denied
Strangely enough, if I directly input sudo kill -9 9669 in the terminal, it successfully terminates the process without any hitch. It's worth noting that on this system, no password is required for commands like sudo tcpdump or sudo kill. Both the subprocess.call method and manual terminal command should theoretically yield the same result, yet only one functions as intended. Where am I going wrong?
