Greetings -
I am using NTP on a fully up to date RHEL3 system (Dell PE2600 hardware). I
use a very basic configuration file (see below) and also use the North
America NTP pool servers. Since I got ntp running properly (I think) about
two weeks ago, I notice a lot of ntp information in my log file (see log
snippet below).
1. I am wondering if this is an indication of a properly (or improperly)
running ntp system?
2. If this logging is normal, are there any recommendations for how I can
reduce the amount of logging?
3. How do I find out what the standard polling interval is, and how would I
reduce the interval if I wanted to?
Thanks.
