Folks,
   If you're interested in the security issues raised by NTP version 2,
I have a technical report that discusses a lot of them, especially the
authentication mechanism and problems.  If you want a copy, you can get
a postscript version by anonymous ftp to dartvax.dartmouth.edu (get
the file pub/dropoff/ntp2sec.ps); if you want a paper copy, send a note
to Deb Minichiello (Debra.Minichiello@dartmouth.edu) asking for TR #154,
"A Security Analysis of Version 2 of the Network Time Protocol NTP."
Be aware that the file on dartvax will go away in a week (on 3/2).
   Enjoy!

Matt Bishop
