Frequently Asked Questions

Find Quick Answers

What permissions are needed to run this tool?

The tool requires tcpdump to be installed on the server and appropriate permissions (e.g., sudo or CAP_NET_RAW) to capture network traffic. See the development tasks for setup instructions.

Can I monitor specific UDP ports?

Yes, you can enter a port number (e.g., 123 for NTP) to filter UDP traffic and only capture packets for that port.

Is this tool safe to use?

The tool only monitors UDP traffic and does not modify network configurations or transmit data. Ensure you have authorization to monitor network traffic on the target system.

What happens if I leave fields empty?

Empty fields use defaults: 'any' for interface, no port filtering, 10 seconds duration, and 50 packets maximum. The tool validates inputs to ensure they are within acceptable ranges.
