retrieving MAC Address

[cschulze7]

No eth=1 option? It occurred to me to extract the MAC addresses for each flow. However, I dont see a way to do that. But in joy.c there is the get_mac_address function. How can I get the ethernet layer info for each flow with the MAC addresses (src and dst) included?

JOY starts processing at the IP layer. The MAC address function is used for displaying the interfaces for a live capture. If you want the Ethernet later information, you would have to modify the function process_packet in module pkt_proc.c. You will see in that function where the Ethernet header is skipped over. Cheers, Bill.

I have a draft solution here: https://github.com/Sotera/joy/tree/mac_addr.

Notes on this ticket. Could use review from C programmers.
