ntpMerlin ntpMerlin - NTP Daemon for AsusWRT Merlin

[Jack Yaz]

I have 384.8_2 on a U86. Since updating to 1.3.0, I need to manually do "ntpmerlin startup" after a reboot or it does not show up in the GUI Tools menu. How can I make this be handled automatically after a reboot?

Check /jffs/scripts/services-start

Which other scripts are you running?

Here's that script.

#!/bin/sh

RC='/opt/etc/init.d/rc.unslung'

i=30
until [ -x "$RC" ] ; do
i=$(($i-1))
if [ "$i" -lt 1 ] ; then
logger "Could not start Entware"
exit
fi
sleep 1
done
$RC start
/jffs/scripts/ntpmerlin startup # ntpMerlin

I see that it's there, but do not know why it does not work.

Other scripts: Skynet, Stubby.

Check that it is executable.

I also notice that's the older way of starting entware, i thought that got moved to post-mount long ago (maybe that's a Diversion only thing)

It is executable, I just checked. I'm not running Diversion. In this case, what do I need to do to start Entware differently?

Jack, a request. Showing a more prominent line horizontally through the zero (0) line would make seeing offset variations more clearly. Thanks for the consideration.

 

[Jack Yaz]

chart.js will be replacing these graphs, but I can't confirm when

After updating spdmerlin to the tidier jffs structure and adding custom cron support, I'm intending to take a break from developing and only fix amy major bugs if reported

 

[Swistheater]

what would cause no stats to be reported on the graphs page?

No stats as in 0s, or no graphs?

 

[Swistheater]

It was a browser issue cancel that. jack is back.

Replying to forums is different to scripting

I had to switch back to ntpmerlin, I like the customizability and the graphs for translating accuracy. Also, I love the new uiDivStats as well. Cannot run without these graphs mang @Jack Yaz

It'll be a good challenge migrating to chartjs with an sqlite backend

Does Network Monitor feature interfere with this working properly? do they conflict with each other?

They should work just fine, there's no interaction

I've been running ntpMerlin for a while and when I check "ntpq -pn" all of the peers listed have a blank tally code. Nothing is identified with a "*" as the primary reference (or any other symbol.) But, when I check "ntpq -c rl" there is a refid peer set. Is this normal? Thanks!

What you describe is not normal.

I thought it was abnormal, but I'm not sure what to do about it. Currently:

no_sys_peer suggests you have the pool command

Maybe the following lines in /jffs/configs/ntp.conf for you are different? The "restrict source" line allows pool peers when using the recommended restrictive defaults.

#
restrict default limited kod nomodify notrap nopeer noquery # restrictive default IPv4
restrict -6 default limited kod nomodify notrap nopeer noquery # restrictive default IPv6
restrict source nomodify notrap noquery # required for pool directive if using restrictive default permissions
restrict 127.0.0.1 # permissive localhost IPv4
restrict -6 ::1 # permissive localhost IPv6

I didn't modify those lines in the default config. This is my ntp.conf:

It might be that you have too many servers in your conf?
Pool will manage the number to be about eight.
Comment out your eight pool servers and use:

pool north-america.pool.ntp.org iburst
server time-a-g.nist.gov iburst
server time-b-g.nist.gov iburst

The pool will include the two NIST servers which are close to you along with six servers from the pool.
