PCAP persmission problems












0















I want to run a c++ program that use pcap as no root.



Because it isn't possible to run it as sudo.



I found this possible solution.



I executed the commands:



sudo chgrp pcap /usr/sbin/tcpdump
sudo chmod 750 /usr/sbin/tcpdump


This is my result:



-rwxr-x--- 1 root pcap 1138288  �  13  2017 /usr/sbin/tcpdump*


This command: getcap /usr/sbin/tcpdump



gives this as result:



/usr/sbin/tcpdump = cap_net_admin,cap_net_raw+ep



But I still get the error:



Could not open enp4s0 - enp4s0: You don't have permission to capture on that device (socket: Operation not permitted)
