Hello,

I'm wondering why I get from ntpq this output :

tfoerste at n22 ~/devel/linux-2.6 $ ntpq -pn
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
*85.25.144.154   143.93.99.252    2 u   84  128  377   29.453   10.241   1.066
+87.32.12.19     4.176.44.157     2 u   88  128  377   50.685    8.234   1.607
+81.169.180.26   192.53.103.104   2 u    4  128  377   31.092   -1.381   1.082

whereas the field "peer polling intervall" of the sniffed network stream shows a value of 8 (==256 sec)
for all packets except packet 3 and 4.
