the following is the exercise I have to complete. but I am not sure what exactly the professor needs. although I know the answers to how to get output but I am not sure how and where to run those commands to get the output. PLEASE HELP!!!!

I have been given a message.log file. I have been asked to filter packets from that message.log file. I am not sure how to do so. in the question, it asks " Using the iptables log file messages.log, find ONE PACKET of data that represents each of the following"

I know how to filter those packets, but it doesn't say if I have to use Wireshark or Linux for iptables.

please help me!!
