[Jack Yaz]

v2.0.2 is available
Changelog:

Use Entware sqlite3 if installed, install automatically for firmware earlier than 384.11

What value does knowing which stratum server you are syncing with add? (i'm unsure, personally!)

Curiosity, like the rest of the stats we are watching

 

[Jack Yaz]

Is there an ntpq command that pulls just the strata?

 

[Swistheater]

ntpq -4 -c rv | grep stratum

this is as close as i can find. note this is reporting your personal stratum status, if you are using ntp.pool.org this value could be continuously changing over time depending on what servers it syncs with.

What value does knowing which stratum server you are syncing with add? (i'm unsure, personally!)

self gratification for some. it is more important to know the stratum you have become on each sync with pool.ntp.org with each time sync this value could change depending on how the servers you sync with changes. if this value becomes some crazy off the wall number, that could indicate that your clock is not sync properly with those servers.

v2.1.0 is available
Changelog:

Add charts for 30 days
Make chart sections collapsible

@Jack Yaz is there supposed to be two prerouting rules in the vserver section of port forwarding, if you enable NTP intercept?

yes

 

[Vexira]

yes

What ports does yours display if I remember correctly mine was 123, but for some absurd reason my VoIP ata stop working, but yesterday when checking the common script apparently my Entware wasn't working so I had to re Install it.
Also thank you, I appreciate it.

@Jack Yaz out of curiosity does the script check if Entware is loaded on boot because I was using your common tool and the graphs bugged out and when I went to re Install it said Entware wasn't present but the NTP graphs were still working ish I just find it strange.

123

connmon still uses the old approach and has a heavier dependency on entware. ntpmerlin only needs entware for ntpd now

Ahh I understand that thanks because I was wondering if that bugged out on me causing NTP to break which breaks time synchronisation and reboot schedule.

I have found a new issue

Jul  7 13:57:34  ntpd[10678]: ntpd 4.2.8p13@1.3847-o Fri May 24 19:54:06 UTC 2019 (1): Starting

Jul  7 13:57:34  ntpd[10680]: unable to bind to wildcard address :: - another process may be running - EXITING

what could be using said Wildcard address ?

firmware's ntpd? but that should be disabled by ntpmerlin - check in System settings (i think)

 

[SomeWhereOverTheRainBow]

since option6:ntp-server is now somewhat supported by dnsmasq, could you add an option for it in your next release @Jack Yaz

it may look something like
dhcp-option=lan,option6:56,[::]

dhcp-option=lan,option6:56,$(nvram get ipv6_rtr_addr) <<--don't know about this one since yours is defined in different DNSMASQ format than the routers built in options are.

Just want to add - busybox actually does a good job at NTP syncing...

Out of my openwrt efforts... this is busybox/sysntpd

3096 root      1200 S<   /usr/sbin/ntpd -n -N -l -S /usr/sbin/ntpd-hotplug -p time1.google.com -p time2.google.com -p time3.google.com -p time4.google.com

Close enough for most purposes...

ntpq -4 -c rv | grep stratum seems to list only the stratum

 

[sfx2000]

*_gateway 71.79.79.71 2 u 50 128 377 0.505 -0.533 0.206

This is busybox sysntpd...

The others are various flavors of ntp and ntpsec on different platforms.

stratum is only one thing in ntp...

lower number - e.g. 2 is higher than 3 - better the stability.
