Well.. As the name might imply.. A NULL scan has no flags set. An Xmas scan has all the flags set, because if you had hardware that had LEDs associated with each flag, it would look lit up like an Xmas tree.. And following the same logic.. A FIN scan only has the FIN flag set. - -- Jon Erickson Cryptologist and Security Designer Caspian 415.974.7081 D49B 4561 1078 0A72 DDF3 7250 8EF4 4681 587E 41DD 1728748 -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 7.0.3 for non-commercial use <http://www.pgp.com> iQA/AwUBPALLQI70RoFYfkHdEQKJ1ACeJrkt3854SyyizIFiCEBiyD4d36AAn1nd kWwEb5/z4q9Tv3APDQXHk0Rx =iNpn -----END PGP SIGNATURE-----
