[WinPcap-users] How to get MAC address from a packet

[Tuan Ha Ngoc Minh]

Dear sir/madam, I’m currently using your windump source code to develop a software which will be used to detect instruder base on MAC address. I have copied and paste one of your example in the Winpcap documentation which filters only UDP packet. I have changed the filter to “arp” then it now captures only ARP packet. What I need to know is how to extract the source (or destination) MAC address from those packets. Could you give me a hint or recommend me any document to help me with that problem ?      Best Regards,         Tuan Ha
