PF is a firewall utility that is available on some BSD-based systems, such as FreeBSD and OpenBSD. It allows you to configure rules that control incoming and outgoing network traffic based on various criteria, such as IP addresses, port numbers, and protocol types.
To display the active packetfilter states and rules in PF, you can use the pfctl command with the -s option.
For example, to display the active states in PF, you can use the following command:
pfctl -s states
This will show a list of the active states in PF, including information such as the source and destination IP addresses, port numbers, and protocol.
To display the active rules in PF, you can use the following command:
pfctl -s rules
This will show a list of the active rules in PF, including the rule number, action, and criteria.
Keep in mind that these commands will only display the active states and rules in PF. If you want to see all of the states and rules, including inactive ones, you can use the -sr option instead of -s.
For more information on using the pfctl command and working with states and rules in PF, you can consult the documentation or seek guidance from the BSD community.
