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?

tshark has no standalone -net or mask flags; capture filters must be supplied via the -f flag using proper BPF syntax, making this command invalid.

This is the stated correct answer, but the flags shown (-capture, -local, -masked, -range) do not exist in wireshark or tshark. The technically correct command is C - sudo tshark -f 'net 192.168.8.0/24' - which uses tshark (the CLI counterpart to Wireshark, suitable for cron jobs) with a valid Berkeley Packet Filter expression scoped to the target subnet. This question appears to contain an error.

Although this is the technically correct tshark command with a valid BPF CIDR filter for the specified subnet, the question marks it incorrect - this is likely a question authoring error.

Wireshark is a GUI application with no -fetch flag; it cannot be invoked non-interactively and is unsuitable for use in cron jobs.
