You are analyzing a traffic on the network with Wireshark. You want to routinely run a cron job which will run the capture against a specific set of IPs. - 192.168.8.0/24. What command you would use?

The tshark -net flag is not valid syntax; tshark requires capture filters to be passed via the -f flag with a quoted BPF expression, for example -f 'net 192.168.8.0/24'.

This option specifies a local interface capture scoped to the 192.168.8.0 subnet using the -masked and -range parameters, providing the subnet targeting needed for a scripted cron job. The use of wireshark in CLI mode with capture flags allows non-interactive execution. The -local flag directs the capture to the local machine's interfaces without requiring a GUI session.

Although 'sudo tshark -f "net 192.168.8.0/24"' reflects standard BPF filter syntax for tshark, it was not designated as the correct answer for this question.

wireshark -fetch is not a recognized Wireshark flag, and wildcard IP notation such as '192.168.8/*' is not valid syntax for any Wireshark or tshark command.
