How to avoid the spoof detection script employed by my isp
Posted 21 June 2008 - 02:11 AM
1)Download Netscan (google It)
2)Open Netscan then press ctrl+o in additional tab check "Resolve Mac Address"
3)Then Click ok . In ip range type first three part of ip eg if ur ip address is 10.10.20.100 you will type 10.10.20.0 then in the to box type again 10.10.20.255
4)Click on scan.It will start scanning from their select an mac address
5) Download etterchange from this site http://ntsecurity.nu...ox/etherchange/ and change your mac address
6)Start Sniffing when mac address get's ban use another mac address from the list
You can detect sniffing through ettercap using one of it's plugin.
Hope it helps!!

in my ethernet lan
there r two vlans
172.16.0.1-255 && 172.16.1.1-255
i was doing APR ARP Poison Routing
and poisoning their mac address so that the data gets redirected at my mac rather than to its default gateway.
Now.. its obvious ... bcz ... once i apr the whole (remember not 1 but the whole) lan.......... internet becomes.. very weak........ for the clients to surf.
and that very day ... i was caught.........! since that very day , even if i sniff two conn. my gateway bans my mac.. i had a word with my ISP guys they said .. they have put in a script .. which when detected spoofing wud bann that very mac.
Now guys above is the scenario i hope this is clear.
Now i wanna ask u expert guys.. firstly how r they detecting whether im spoofing or not secondly .. are they just bluffing and keeping a close look at my mac .
I used cain.. while sniffing .. even i sniff two conn my mac gets bann in winxp
i used arpspoofing , fragrouting and ettercap again arp poisoning .. and stil i gets banned
though i was reading some RFC regarding spoofing and if theres any script that can detects arp spoofing.. and i almost found that underlining concept.. ill surely post it here.. may be we can get some hint from their.
for all of ur support till now!

That in mind, ARP spoofing isn't an easy thing to spot, but there is some software that tries to stop ARP spoofing If you could provide us with the models of your networking equipment, we may be able to figure out what kind of IDS they have set up. (Also if you have admin access to this equipment you could always telnet in and use the "ps" command to see what they're running)
