I installed Wireshark on a Clear Linux instance with the command:
sudo swupd bundle-add wireshark
I got the following error when I was trying to capture on a network interface as a non-root user:
The capture session could not be initiated on … Please check to make sure you have sufficient permissions. …
I followed the steps on this page, which apply to a more general situation.
In the case of Clear Linux, the group
wireshark should have already been created after the installation. The following steps are necessary.
Add yourself to the group:
sudo gpasswd -a $USER wireshark
Change the group of
sudo chgrp wireshark /usr/sbin/dumpcap
sudo chmod o-rx /usr/sbin/dumpcap
Set network privileges:
sudo setcap cap_net_raw,cap_net_admin+eip /usr/sbin/dumpcap
