So where is the cisco getting the 8-12 spread is a mystery indeed. It's clearly a bug. Maybe try a different code on the cisco?
Or maybe the cisco box is deeper in gravitational well than the rest of the setup -resulting in its clocks to tick slower according to the general relativity :) adam _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
