Hi,
I'm trying to use ntpd with gpsd on a linux system, but am unable to get ntpd
to update my system clock.
I'm using the first SHM segment only (127.127.80.0) and do not have a PPS
signal available. I know that gpsd is running, has a 3D fix and is writing
into the SHM segment.
Running
NTP client was not able to detect the IFF config files because the crypto_flags
in crypto_setup() shows the following line
crypto_setup: setup 0x80001 host myclient md5WithRSAEncryption
I'm using 4.2.5p158 and have the following configurations.
$ cat /etc/ntp.conf
server myserver.domain.com
If on the NTP client only host, there is no ntp-keygen but openssl is
available, what are the equivalent openssl commands to generate certificates
with the Schnorr (IFF) scheme?
Thanks.
Victor

A reasonable expectation of a cheap crystal is 50ppm static plus
10ppm temperature dependent. When one gets 500ppm it suggests the
problem is rather worse than poor crystal tolerancing.
I am inclined to agree. One reference I found was this:

This seems to suggest crystals have quadratic temperature dependency.
My understanding is that normal cuts have cubic dependency. Of
course, 32kHz crystals are often cut for wrist watch use, and

Depending on where you want to see that UTC value, you could maybe define
a UTC timezone with a 15 second offset.
Of course time() would still return GPS, but the displayed time in
applications would be UTC.

Victor,
See the cryptotype table on the Authentication Options page. If a client
needs IFF identity, all it needs is the IFF parameters file; the rest is
automatic.

Apparently, you are following advice on other than the
online/development documentation, but I can only speak from the latter.
I reread the authentication options and ntp-keygen pages looking for
possibly misleading directions and believe the prose is correct. The

Victor,
Look in the ntp-geygen source file. See the gen_iff() routine. Look in
the ntp_crypto.c file for the crypto_alice(), crypto_bob() and
crypto_iff() routines.
