in my output from ntpdc -s i get the following
$ ntpdc -s
     remote           local      st poll reach  delay   offset    disp
=======================================================================
*x.x.x.x  10.0.0.15   2   64  377 0.00018  0.029325 0.00363
.x.x.x.x 10.0.0.5   2   64  377 0.00017  0.030048 0.00325
what does the asterisk mean and the period mean before the server name?
