ntpMerlin ntpMerlin - NTP Daemon for AsusWRT Merlin

[Butterfly Bones]

Smooth install on both AC86U and AC68U via amtm. Redirection works perfectly. No change in CPU usage. Great job guys!

@Jack Yaz after install I edited /jffs/configs/ntp.conf with my closest servers. Does ntpmerlin require restarting to apply these changes?

I always do.

/opt/etc/init.d/S77ntpd restart

Thanks for your reply We have great members on these forums.

How can I fix my ntp client? I keep getting this error also and have been for some time now.

Mar 31 11:09:47 crond[1110]: time disparity of 475804 minutes detected

You should only get the crond message once at the very end of the boot process. If that is all it is, then it is not a problem. It is probably the number of minutes since the default date/time of May 5 1:05 AM

First, ensure ntp client configuration is correct. Something like:

/opt/etc/init.d/S77ntpd restart

Yes, ntp.conf changes require ntpd restart

 

[L&LD]

Yes, ntp.conf changes require ntpd restart

/opt/etc/init.d/S77ntpd restart

This is a good candidate for a new menu option.

Yes, I wasn't sure about the crond message. I have the same settings in my basic config. I don't know what the problem could be. Like I said before, When ever I schedule a reboot or reboot from the button on the back of the router, everything boots fine. It's just when I press the reboot button in the gui. Also my vpn client doesn't boot back up when I have this problem.

Just know that the options for that command are

/opt/etc/init.d/S77ntpd start | stop | restart

And submenu's now too!

Boy, this sure gets complicated, very fast.

(Not difficult for the script guru's here, just much more checks and balances needed than the mere physical difference of 'oh look! another option for us!' that seems like it is a few characters 'extra' code.

I can port YazFi's config editing code

I think the restart command would be handy in the menu, not sure start and stop are that useful for most users. The config editing would be icing, and might be nice for those not familiar and comfortable with Linux CLI commands, or combing through scripts with an editor....

All these scripts offer so much already, and give me incentive to learn more and more and more.
If you want to add config editing, I'm sure many will appreciate it.

That would be icing on the cake. If it's not too much trouble... and a big Thank you too!

I’d really like that! Plus an auto restart command after applying changes!

I'm in the uk and the graph was jumping like a box of frogs using the uk.pool.ntp.org so I blanked them for some other stratum 1 servers and now the chart is very good.

If anyone's interested.

#server 1.uk.pool.ntp.org iburst
#server 2.uk.pool.ntp.org iburst

Love your "box of frogs" description!

Same here, I just narrowed my selection down from the entire USA to just West Coast.

You can see where I changed the servers over.

Also my vpn client doesn't boot back up when I have this problem.

I was under the impression that when you use the reboot button that at some point nothing is running as it resets. So if things were not shut down gracefully, well they go down hard.

But your experience suggests that this is not the case. I do not have a guess how there could be a difference between off button reboot and webgui reboot button.

There are two scenarios for why the ntp client does not sync.

One is that there is no internet. Looking through my logs led me regard this as not likely. However, I do not use a router VPN client which complicates things.

The other is that the ntp client cannot lookup 0.us.pool.ntp.org. Since I have another NTP server on my LAN, I am using an IP addres for the ntp client to connect to, thus avoiding the possibility of a DNS lookup issue. I am also using stubby. I raise stubby because the installation places a line in the dnsmasq configuration just for the ntp client to lookup pool.ntp.org possibly before stubby is ready. Do you have such a line in your dnsmasq config, possibly for dnscrypt? If not, I wonder whether it could help.

# grep server /etc/dnsmasq.conf
server=127.0.0.1#5453
server=0::1#5453
server=/pool.ntp.org/1.1.1.1

The last line tells dnsmasq just to go to Cloudflare to lookup pool.ntp.org. You could have another line for your VPN provider.
