Re: [ilugd] Re: Promiscuous Mode of Ethernet
that's absolutely right. Sniffers/Protocol Analyzers like Ethereal are best admirer of this mode. as soon as u start Ethereal or xyz sniffer and select a perticular card, that card will be put up in promiscuous mode and that's how u get whole frame from network even the frame which your machine was not supposed to see, can be seen with that. and when etherreal is closed, you start getting only the frame which were intended to your machine. ** my comments are not for 802.11 network cards ** regards, Puneet - Original Message - From: Abhijit Menon-Sen [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, January 10, 2004 9:22 AM Subject: [ilugd] Re: Promiscuous Mode of Ethernet At 2004-01-10 03:42:24 +0530, [EMAIL PROTECTED] wrote: Every Ethernet card has a hardware (MAC) address.

Hi AMS, I am sorry but I couldn't get *(instead of only those that are addressed to it)*. Yeh baat kuch hazam nahi hui... Please elaborate :-( Regards, Gurpreet Singh Sachdeva At 2004-01-09 02:02:33 +0530, [EMAIL PROTECTED] wrote: What exactly is promiscuous mode? It's a mode in which an Ethernet card receives all frames on the network (instead of only those that are addressed to it). In this case, tcpdump is setting the promiscuous mode on your interface, which will return to normal when you exit tcpdump. I would appreciate it deep from my heart if someone explains it deeply... Did you ask Google about promiscuous mode? -- ams ___ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd ___ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd

The relevant dictionary meaning for Promiscuouos is Lacking standards of selection; indiscriminate.
