Re: [Ptpd-devel] PTP issue.....need help.

[Moschowits, A. <avi...@gs...>]

Folks,

I have been using PTP_V2 (think it's probably release 87), for quite a while. I have recently run into an issue, & was looking at later code in Source-Forge as well as head release 153,  and came across the release of v2-branch 142, I tried to compile both and run the branch/v2 code. I'm running on Linux-RH5 2.6.18-128.1.6.el5.

Previously I run my clients with the following command options:

        ptpd2 -b eth? -i 0 -T 2 -h -m 6 -f ... /ptpd2.log -D -g -x -O 500000000

Trying the same options with the latest release I get the following errors
# Timestamp, State, Clock ID, One Way Delay, Offset from Master, Slave to Master, Master to Slave, Drift, Last packet Received
2011-12-01 17:15:26.940988, init
2011-12-01 17:15:26.973823, flt

In order to get more verbose output, I have added the debug version and get this
ptpd2_v2_debug -b eth? -C -i 0 -T 2 -h -m 6 -D  -g -x -O 500000000

   (ptpd info)     17:18:48.421136  (___)    Info:    Going to check lock /var/run/kernel_clock
   (ptpd info)     17:18:48.430447  (___)    Info:    No ptpd daemons detected in parallel (as expected)

   (ptpd notice)   17:18:48.495316  (flt)  self shutdown, probably due to an error

I then took a step back, and try and figure out which is the latest branch of V2 that still works for me.  It seems release 135 is the latest release that does not suffer from above issue. Can you help me understand what the issue is?  Or suggest what to do next?
