Hello @moots

It’s not quite clear from your post, but I guess this is running Vyatta routing software, ntp runs for a while then the time drifts?

My questions would be:
Is that the only “server” line in the config file?
Are there any useful ntpd messages in /var/log/syslog?
192.168. is a local LAN address - is that machine running correctly?

1.yes
2.


3.sometimes ntp can sync time
