I have ntpd running with the following in /etc/conf.d
Quote:
# Generated by udhcpc for interface ethm
restrict default noquery notrust nomodify
restrict 127.0.0.1
restrict 195.13.1.153 nomodify notrap noquery
server 195.13.1.153driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp.log


It is good that udhcp writes this, as the upstream server may change.

On the other hand, as I wish this ntpd instance to also be a server for my subnet, I would need an additional line
Quote:
restrict 192.168.4.0 mask 255.255.255.0 notrust nomodify notrap


If I add that line manually to /etc/ntp.conf, it gets overwritten whenever I get a new ip from upstream.
I guess, I would need to provide that line in some other file, but could not find where I should specify this.

You could use dhcpcd instead of udhcpc as dhcpcd's NTP hook script just adds to the existing configuration instead of whole heartedly changing it.
