NTP update not working well

I just had to chnage my ntp conf again to get ntp working correctly…

Before

[root@wr-fw ~]# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================

restrict 127.0.0.1

after

Hi all,

all right, let’s shed some light on this…

This is completely intentional. Please refer to the NTP Pool Project’s homepage for further information on how the NTP pool architecture works.

ntpd sometimes gets confused if the internet connectivity is flapping. Because of this and some other reasons, we decided to move on to chrony, being a more robust software with a smaller footprint. Unfortunately, time is currently short, and priorities laid elsewhere (kernel 5.10.x in particular).

Thanks, and best regards,
Peter Müller

I have a local GPS timeserver, updating from it hourly doesn’t sound great (yes i can edit the config directly).
I did find it counter-intuitive when i set an ntp server in the gui, it’s using that for settime as opposed the ntp service.
chrony would be nice.

hi !

as i remember i posted here somewhere lfs for chrony (i have it running on my ipfire) … but if you want to use gps with sense , you need also the PPS signal which is provided by satelites. for this i use 2x Pi4 with this module (ipfire runs with a USB-DCF77 module)
I did not figured out how to use gpio pin of my APU board…

NTP issues are fixed in IPFire 2.27 - Core Update 169 released.

see:
