==Non-Root Capture==
sudo apt-get install libcap2-bin
sudo groupadd wireshark
sudo usermod -a -G wireshark kirat
newgrp wireshark
sudo chgrp wireshark /usr/bin/dumpcap
sudo chmod 750 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
 
Verification:
getcap /usr/bin/dumpcap => /usr/bin/dumpcap = cap_net_admin,cap_net_raw+eip
 
If still unable to capture:
sudo dpkg-reconfigure wireshark-common
sudo chmod +x /usr/bin/dumpcap
