# INSTALLING WIRESHARK ON UBUNTU 14.04 LTS
sudo apt-get install wireshark
# No interface can be used for capturing in this system with the current configuration
# If you run wireshark as a non root user at this stage (see image above), you will get the message “No interface can be used for capturing in this system with the current configuration.”.
# The following steps will rectify this.
#
# Create the wireshark group.
sudo addgroup -system wireshark
#
# Add your username to the wireshark group
sudo usermod -a -G wireshark $USER
#
# Change the group  ownership of file dumpcap to wireshark
sudo chgrp wireshark /usr/bin/dumpcap
#
# Change the mode of the file dumpcap to allow execution by the group wireshark
sudo chmod 750 /usr/bin/dumpcap
#
# Grant capabilities with setcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
#
# Verify the change
sudo getcap /usr/bin/dumpcap
#
# At this point, you will need to log out, then back into Unity.
# You should now be able to run Wireshark as a non-root user, just as long as that user is part on the wireshark group, everything should just work.
