Well, they are not readily available. I used a non-public extension to Bro (that is not mine) to get the RTT samples. So, that is a sticking point. And, then there is a ball of goop to analyze those. If folks have a place they can monitor and are interested in doing so, please contact me. I can probably get this in shape enough to give you. But, I doubt I'll be able to somehow package this for general consumption any time soon. allman ----------ma58984-1 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (Darwin) iEYEARECAAYFAlDs5mgACgkQWyrrWs4yIs53FwCglRIBe7pb/RPQUz1Yjsi9Up4w AtAAmwS8TGQrigitpCO6vcofxY7rjOy+ =9mNY -----END PGP SIGNATURE----- ----------ma58984-1--
