hello all,

I can launch NTP by :

/usr/sbin/ntpd -n -N -l -S /usr/sbin/ntpd-hotplug 0.openwrt.pool.ntp.org ntp.lothaire.net ntp.ciril.fr 1.fr.pool.ntp.org debian.org
When i use Luci web client and use it to configure ntp the result is :

/usr/sbin/ntpd -n -N -l -S -p /usr/sbin/ntpd-hotplug -p 0.openwrt.pool.ntp.org -p ntp.lothaire.net -p ntp.ciril.fr -p 1.fr.pool.ntp.org debian.org

and so it doesn't start.

In my init script /etc/init.d/sysntpd I changed the line 55 by :

procd_append_param command $peer
(removed -p)

and look like it's work perfectly.

I tested this using OpenWrt 19.07.3 built from source,
and I expect it to be just the same in earlier versions.

First I entered the server names through LuCI, restarted sysntpd and checked the process...
# ps ww | grep ntp
27406 root 1072 S< /usr/sbin/ntpd -n -N -l -S /usr/sbin/ntpd-hotplug -p 0.openwrt.pool.ntp.org -p ntp.lothaire.net -p ntp.ciril.fr -p 1.fr.pool.ntp.org -p debian.org
27464 root 1072 R grep ntp

Almost the same as reported, except I also set as an NTP server (-l option) and a -p for the final debian.org.

Stopped the sysntpd init process, so I can test at the terminal.
Also, set the 'initscript' variable so the hotplug scripts don't complain,
and clear /tmp/state/dnsmasqsec so I can see the "stratum" message when the first good server response is accepted,
and -d -d -d to see the debug output.
# rm /tmp/state/dnsmasqsec

initscript=ntpd /usr/sbin/ntpd -n -N -l -S /usr/sbin/ntpd-hotplug -p 0.openwrt.pool.ntp.org -p ntp.lothaire.net -p ntp.ciril.fr -p

...etc...

All looks OK, except for duplicate peer ntp.ciril.fr (193.50.27.66)

ntpd -n -w -p 127.0.0.1

(Note: the refid matches the earlier 85.199.214.102)

So, looks like it is working correctly.

Furthermore. Running with all the -p options removed gives NO DEBUG OUTPUT...

initscript=ntpd /usr/sbin/ntpd -d -d -d -n -N -l -S /usr/sbin/ntpd-hotplug 0.openwrt.pool.ntp.org ntp.lothaire.net ntp.ciril.fr

1.fr.pool.ntp.org debian.org

This is the same as....

initscript=ntpd /usr/sbin/ntpd -d -d -d -n -N -l -S /usr/sbin/ntpd-hotplug

then in another terminal.

ntpd -n -w -p 127.0.0.1

The NTP server is acting as its own independent clock source (stratum:1)
This is as the code is designed -- all working as expected.

I'm going to recommend closing this, and the other two duplicates, with no problem found.

Thanks for digging into that.

I'm also seeing no issue with either 18.06 or 19.07, closing.
