Thanks. Could you say a bit more. If I start with 4 PCs plugged into a low end 5 port switch, what else do I need to make a working PTP setup? Do I have to buy a fancy GrandMaster or can one of the PCs serve that function? Low cost switches aren't going to update any packets. Will that screw things up if the reason I want the clocks in sync is to measure network queuing delays when there is a lot of network traffic? Is there a HOWTO for getting started? ------- Since you mentioned PTP, can we use the PTP time stamping stuff to get better time stamps for NTP packets? (without dragging in any/much PTP stuff) -- These are my opinions. I hate spam. _______________________________________________ devel mailing list devel@ntpsec.org http://lists.ntpsec.org/mailman/listinfo/devel
