Hello and good day! I've installed Wireshark on a Linux server and use tshark with the command line to capture network packets. Tshark ran for several months capturing packets but now hangs:
tshark -help
Running as user "xxxxx" and group "root". This could be dangerous.
tshark -z
Running as user "xxxxx" and group "root". This could be dangerous.
tshark -Nnm -t ad -c 1 -i br0 -i eth0 -T fields -e frame.number -e _ws.col.Time -e frame.interface_name -e frame.protocols -e frame.len
Running as user "xxxxx" and group "root". This could be dangerous.
All tshark commands stop at this same location. So for I've tried server reboot, remove/reinstall Wireshark/Tshark, and system reset to factory default/reinstall Linux. General web search suggests Wireshark/tshark permission issue but I'm unsure if permissions issue because tshark commands previously worked for several months.
Has anyone seen this type of issue or can provide suggestions how to correct?
