Some proprietary protocols transmogrify almost daily, it’s not easy keeping up! Send e-mail with the dsnifc “subscribe” in the body of the message to dsniff-request monkey.

Of course, the traffic must be forwarded by your attacking dsnkff, either by enabling kernel IP forwarding sysctl -w net. ICMP port unreachables to the local DNS server, a result of dnsspoof winning the race in responding to a client’s DNS query with forged data excessive, or out-of-window TCP RSTs or ACK floods caused by tcpkill and tcpnice dsniff’s passive monitoring tools may be detected with the l0pht’s antisniff, if used regularly to baseline network latency and if you can handle the egregious load it generates.

Firewalls can be a mixed blessing – while they protect sensitive private networks from the untrusted public Internet, they also tend to encourage a “hard on the outside, soft on the inside” perimeter model of network security.


You can only arpspoof hosts on the same subnet as your attacking machine. Why do I get “Socket type not supported” on my Cobalt Linux box?
