in thread ARP Poisoning

ARP poisoning is the act of broadcasting malicious reply packets and update the ARP caches of the systems on the network, my code does this very happily and in a very legitimate sort of way. i've checked it using the tcpdump sniffer and it does not reveal my own IP and moreover the change in the ARP cache can be seen using the arp -a command i've checked it and it does update the MAC address of the gateway replacing it with my MAC

=====================================================
i'am worst at what do best and for this gift i fell blessed...
i found it hard it's hard to find well whatever
NEVERMIND

    Sigh..all right, I've really run out of patience with you, but to end this off on a semi-helpful note I'll reply briefly. Read this, then read my post above again, think about it, read a book and maybe you'll get it.

    s/is the act of broadcasting/amongst other things requires sending/;

    No, it does this in the dumbest and least efficient way possible.

    checked it using the tcpdump sniffer

    Hint: tcpdump does not explain the whole packet to you, you won't actually see the ARP payload unless you manually inspect the packet content yourself (it shows you the Ethernet frame data, which is not necessarily the same as the ARP payload).

    it does update the MAC address of the gateway

    Newsflash: just because it works on your router, doesn't mean it'll work on others.

    Oh, and I thought this was your network administrator's router? You know, the one who was so happy you notified him of this "vulnerability"...don't bother replying, I won't.


    All dogma is stupid.
