Well, with all the clients now reporting this machine as a stratum 3 and
fractions of a millisecond for an ntpq -p, and this machine reporting 5
servers and one BCST at a st=16, and it goes out on the net and checks
all servers before ntpq -p is completed, take 5 or 6 seconds to do that,
I'd have to say its working. dd-wrt hasn't an ntpq -p output, so I've
left it to its own devices, listing its server as pool.ntp.org. It
doesn't seem to have a switch to turn on .BCST. That does seem odd as
ISTR seeing it in an older version.
So I think I've done my part to reduce the load on the debian stratum 2
servers pool. TANSTAAFL.
