Hi, is that an MS "feature"? ;) Because, to capture _only_ ARP packets in Ethereal you can specify the filter arp after hitting Ctrl-K (Capture). Same effect with "tcpdump -i eth1 arp". However, I didn't try that on Win yet... ARP packets are not being handled by the hardware only. It would be virtually impossible to create them with Nemessis then. Other wicked things would not work too (ARP-Flooding, f. ex.). You can even change your MAC jit, at least with Linux... I suppose you have to turn the arpspof preprocessor on as well in order to alert on ARPs. Regards, Edin Spencer, Arthur wrote:
