4. ICMP/UDP probes I do not like these probes just because when a target has an open TCP port, we are not totally assured that a firewall in-between is not crafting responses for these tests. So, you may end up with a fingerprint generated in part from the true target, and in part from a false target, leading to a bad detection.
I agree. This has been discussed several times under the "nmap doesn't correctly detect BLAH" subject. Lots of people miss the fact tht there are LOTS of devices between you and your target, like in packet-forwarding/NAT/DMZ configurations. - -- Arturo "Buanzo" Busleiman - VPN Mail Project - http://vpnmail.buanzo.com.ar Consultor en Seguridad Informatica - http://www.buanzo.com.ar for f in www blog linux-consulting vpnmail; do firefox http://$f.buanzo.com.ar ; done -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFEdzf7AlpOsGhXcE0RAmudAJwLl7yrXFqIf6ucCVTeWriGW7MHjACfYKQ+ hzhEDh0ii9qdqXb5mLBRNB4= =0yrz -----END PGP SIGNATURE----- _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev
