On and off I have been receiving error messages from various pieces of equipment about NTP errors from my pool of Symmetricom receivers. I finally found NTPTool at: http://www.geardownload.com/internet/ntp-server-tool-download.html (Click on the blue "download" image above the thumbnail image of the screenshot) It lets me flood NTP requests to my servers and I was able to find which one was dropping replies under high traffic. (I was able to open multiple instances and generate thousands of requests per second). (Problem solved - Bad gig SFP in the switchport connecting to the server) _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
