Dear Maintainer,
we use two physical servers with a serial attached DCF 77 module
(EMC Professional 3001), connected to ttyS0. Both machines
worked fine with Debian jessie. Since the upgrade to Debian stretch
both machines fail to decode the time from the module:
root@isis:/var/log# ntpq -c clocklist
associd=0 status=0012 1 event, clk_bad_format,
device="HOPF 6021", timecode="\x02\x0c\x09140700140518\x0a\x0d\x03",
poll=11, noreply=0, badformat=1, baddata=0, fudgetime1=1.700, stratum=0,
refid=DCF, flags=0, refclock_time="<UNDEFINED>", refclock_status="",
refclock_format="hopf Funkuhr 6021",
refclock_states="NOMINAL: 00:00:54 (7.74%); *BAD FORMAT: 00:10:43 (92.25%);
running time: 00:11:37"
root@isis:~# tail /var/log/ntp.log | grep FAIL
14 May 15:56:59 ntpd[32050]: PARSE receiver #0: FAILED TIMECODE:
"\x02\x0c\x09135700140518\x0a\x0d" (check receiver configuration / wiring)
I also tried the newest Debian version from testing and unstable (just
backported it to stretch, hence the package version), but the problem
stays permanent.
The online GUDE documentation from
http://wiki.gude.info/Ntpd_Installation
contains an installation script for ntp which uses upstream source, but also
contains three patches. If I apply the last one (clk_hopf6021.diff) to the
stretch package the clock gets recognized again and works perfectly.
So please include this patch in the next stable (and testing) ntp package
to make GUDE clocks work again.
Thanks,
Christopher
