Re: [CentOS] HOWTO Stratum 1 NTP server under CentOS 7
Alexander, First off, CentOS7 came with cronyd. Which was very annoying because when I tried to remove it, it had 2 prereqs: anaconda initial-setup Now, I don't know why the setup program kept these 2 around. I think CentOS7 needs a bit growing up. Anyway, I disabled chrony: systemctl disable time-sync systemctl stop time-sync Then I installed ntp. However, when I started it it seems that it was not compiled with: --enable-all-clocks So, I downloaded the latest and re-compiled with: ./configure --with-crypto --enable-all-clocks --enable-step-slew I built it as per the document and everything looks good -G On 12/12/2014 04:29 AM, Alexander Dalloz wrote: Am 11.12.2014 um 21:57 schrieb xaos: Hello everyone, If anyone is interested, I have created a HOWTO on running a Motorola GPS receiver connected to a CentOS 7 box via serial port (com1), with 1PPS over DCD.

'initial-setup' is the program that runs on your first boot, and it
requires 'anaconda'. 'anaconda' requires the 'chrony' package.
Services in the default install require a time-sync daemon, and chrony
is the default, so this isn't really unexpected. Once a system is set
up, it doesn't remove the initial-setup package.
Then I installed ntp. However, when I started it
it seems that it was not compiled with: --enable-all-clocks
That doesn't seem to be the case. Looking at the NTP spec file, I
see:
%configure \
--sysconfdir=%{_sysconfdir}/ntp/crypto \
--with-openssl-libdir=%{_libdir} \
--without-ntpsnmpd \
--enable-all-clocks --enable-parse-clocks \
--enable-ntp-signd=%{_localstatedir}/run/ntp_signd \
--disable-local-libopts
(check the git.centos.org version yourself:
https://git.centos.org/blob/rpms!ntp.git/dbacec4466ee70248db634b110bfad8a2b74cd82/SPECS!ntp.spec
)
As far as I can tell, there is literally no reason why you can't use
the packaged ntpd.
If you are having a problem with getting the packaged ntpd working, I
suggest filing a bug against the RHEL package. The package has many
patches, perhaps one of them is interfering with detecting your
device.

Re: [CentOS] HOWTO Stratum 1 NTP server under CentOS 7
Jonathan,
I would much prefer to run out-of-the box. No question!
BTW, on other machines that I installed CentOS7,
chrony, was not there. Neither was anaconda or initial-setup.
This was after the install, naturally.
Ok, so maybe this box was unlucky. It was installed the same day
as Centos7 came out. I will re-install, update and see what happens.
Quite often the problem lies between the computer and the chair.
Update to follow...
-George
