finding communicating devices on network

  • retag add tags

I'm new to wireshark and was wondering what filters you should use to be able to tell which devices are actively communicating on the local area network. By active I mean devices that are both receiving and responding to traffic. I just opened a Pcap file that has thousands of packets so I'm having trouble figuring out how to remove the packets where, for example, a computer only sent out information and then shut down so it couldn't receive anything and is therefore not active.

To be honest I think it is unclear what you are trying to determine.

Maybe look at the Conversations dialog (from Statistics -> Conversations) that shows what endpoints are communicating.

The next step would be to filter with ip.addr == 10.1.2.3 if you think that machines is active by your definition.
