![]() ![]() This is the reason why you see packets not meant for you. However, Wireshark changed that, telling the interface firmware/driver that you actually want any packets arriving to it. This is done using the information encoded in the DST MAC field: if the destination MAC is equal to the interface MAC, the packet is accepted, otherwise it is dropped. For the current version of Wireshark, 1.8.6, and for earlier 1.8.x releases, the capture filter dialog box is no longer available in the capture options window. Normally, when an interface receive the packets, it check if it should grab and process it or if it should discard the received frame. So the real question is: why packets from others IP arrive at your interface? It is due to how wireless ethernet networks work: the AP basically use its radio interface to broadcast packets to all nearby listener. ![]() This article does not cover network intrusion detection, which is documented separately. You may use tcpdump, Wireshark or even collect data from a switch and send it to a remote analysis system. If needed you can download separately from the Npcap web site. How to capture, filter and inspect packets using tcpdump or wireshark tools OpenWrt is a versatile platform base on GNU/Linux, offering state-of-the art solutions.

Wireshark, being a network sniffer, put both the interface firmware (if present) and driver into promiscuous mode, meaning that it instruct the network stack to capure any packets arriving at your interface. Each Windows package comes with the latest stable release of Npcap, which is required for live packet capture. It doesnt give any > error, just sits there not capturing anything although in the bottom > panel I can see: eth0: live capture in progress message. ![]()
