This is a list for beginners, so while your question may be naive, it is hardly stupid. I mention this because I was struck by the large number of people apparently interested in discussing your syntax, but themselves either unable or unwilling to include an *answer* to the question in the messages they posted. Shame on all of you. Normally, the firmware in a NIC filters incoming traffic and passes to the OS only those Ethernet frames that are addressed to the NIC's hardware (MAC) address. When in promiscuous mode, the NIC firmware passes ALL Ethernet frames up the ladder, not just ones sent to its MAC address. tcpdump is probably the most common app that uses promisc mode, but there are others. -- -------------------------------------------"Never tell me the odds!"-------- Ray Olszewski -- Han Solo Palo Alto, California, USA [EMAIL PROTECTED] ------------------------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
