hi, Can we create multiple PTP masters on 1 physical Ethernet port using virtual IP addresses? if it is a yes, how many IP addresses ptp4l can support on that port? thanks, Tim N.

I am trying to run ptpd with multiple slaves, but I cannot figure out how to achieve it. in my /etc/default/ptpd file I currently have "PTPD_OPTS="-M -i ens10f0" If I try to add one more interface here "PTPD_OPTS="-M -i ens10f0 ens10f1" it does not work. I tried launching ptpd twice with single interface, but does not work. I am using ubuntu 18.04.

Hi all, I'm having this same issue: the clocks take a long time (in the order of ten minutes) to synchronize when starting with an offset in the order of 100 ms. I'm running a system that cannot be kept powered up between uses. I see that some features @wowczarek mentioned, such as preserving the kernel frequency, have been implement in the newest version. However, I'm interested in what @Jan Breuer mentioned: how to lower the threshold for stepping the clock from 1 second to 10 ms, for example?...

Allan, OK - that would explain the reported empty messages received - as per the comment in the sources "mesage without a timestamp considered harmful". This is likely a driver issue. While for TX timestamps, PTPd has its own way of dealing with waiting for them - for RX timestamps it follows the API and does nothing special. Thanks, Wojciech

Hi there, What you are seeing is actually a "side effect" of the driver / OS not being able to capture the transmission timestamps of the delay request messages. This is a notorious problem with many cards and drivers, almost to be expected. Ptpd silently ignores this, but as a result you have sequence gaps, because the transmitted delayResp - which is physically transmitted - is considered not sent, and the response comes back, but is dropped. I think I will need to rework this, because this behaviour...

Hi! The Altera Cyclone V Soc has IEEE1588-2008 support in the MAC hardware. I have the 'wowczarek-2.3.2-libcck' branch working, mostly. The problem is, is that the sequence-numbers will occasionally get out of sync -- I'm including a snippet of the log-file that indicates this: 2017-06-29 20:58:05.189102 ptpd[558].(debug1) Received an empty PTP message (this should not happen) - ignoring 2017-06-29 20:58:05.189197 ptpd[558].(debug1) ==> DelayResp message received, sequence 36414 2017-06-29 20:58:05.189241...

Whenever I tried to play any game on my pc, I was facing the same high CPU usage problem. Searched a lot and found that problem may be cause by svchost.exe (netsvcs)

i wanted to ues ptpd in WLAN with one master and many slaves. slaves know master ip addr, but master do not know slave, so I uesd negotiation . E2E negotiation is ok, but P2P i can not configure well。 is master need two ptpd process in p2p mode？ can recommend a suitable configuration for me? thanks

Hi, The truth is that it doesn't really matter, because the slaves also run the BMCA, so even if two masters become active, slaves will select only one anyway. When the active master goes away, the other two will wait n * announce interval (configurable) and will consider themselves best and will start transmitting, possibly both. But soon after the "worse" of the two receives the first announce message from the "better" one, it will stop being master. Actually not as soon as, but soon.How long this...

Hi everybody. I have a question considering BMC algorithm in PTP. For example, if I have 3 nodes, in normal case, one node is grandmaster to other 2 nodes (grandmaster is connected with second node and second node is connected with third node) . But if I restart grandmaster node, is it possible that both of other two nodes become master? If it is possible, can you please explain how? Shouldn't BMC algorithm choose better from those two as master? Thanks in advance

Probably i have the ptpd.conf by default (and my eth0 is not defined) so gives me the error i described, im reading this: Anyone know where i can define the config file? im using buildroot and this way: https://gist.github.com/mhaberler/f4809ed2e465912d3534 it should work for ptpd2 or only for ptpd? shoud i rename the file for etc/default/ptpd2 instead of etc/default/ptpd ?

Hi Folks, i'm using ptpd2 v2.3.1 and can synchronize clocks between my Vmware and my slave in Unicast. When i try multicast gives me that error: (init) failed to join the multicast group (strerror: No such file or directory) Im using an custom kernel version 4.11.0-rc5. I thhink probably the problem is this erros in my logging dmesg: " Starting ptpd2: random: crng init done Configuration error: option "ptpengine:interface" is required Warning: Unicast negotiation can only be used with unicast transmission...

Hi, I am not sure what this question has to do with PTPd. Were you meant to post it somewhere else? Thanks, Wojciech
