Hello there!
Some words about the context of my problem: I have several systems whose
system clock skew I want to measure remotely (does that sound familiar
to you :-). These systems run NTPD configured for a reliable time server
and cunningly use the option "disable ntp" so the kernel frequency
discipline is disabled.
The skew is the first derivative of offset with time. To read the offset
remotely I use ntpdate. Now some people and
https://ntp.isc.org/bin/view/Dev/DeprecatingNtpdate say, I should use
sntp instead.
So I went ahead and compiled sntp. Running sntp against the above
mentioned systems gives me the following error:
Incoming packet on socket 0:
dc0008f1 00000000 001209d0 494e4954 00000000 00000000 c7c8f4ed 1a280000
c7c8f4ec 64275254 c7c8f4ec 6438b04a
sta=3 ver=3 mod=4 str=0 pol=8 dis=18.038330 ref=0.000000
ori=3351835885.102173 rec=3351835884.391225
tra=3351835884.391490 cur=3351835885.103798
sntp: Unusable NTP packet rejected on socket 0 (f=0, status 3, version
3, stratum 0)
Looking at the source code of sntp, read_packet() in main.c complains
about data->status == 3
Why is that?
Cheers
Daniel
