NTP socket then kernel time error

Hey,

I have an error with my NTP daemon. When I check its status for the first time with

systemctl status ntpd.service

here is the output:

Oct 26 17:14:42 myhost ntpd[377]: unable to create socket on enp2s0 (5) for fe80::493f:8ce3:2992:16b5%2#123

Oct 26 17:14:46 myhost ntpd[377]: new interface(s) found: waking up resolver

It seems to be an IPv6 error.

Then, when I restart the service, and that I check its status again, I get another one:

Oct 26 17:18:13 myhost ntpd[1178]: Listen and drop on 0 v6wildcard [::]:123

Oct 26 17:18:13 myhost ntpd[1178]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized

This time it is a kernel time error.

My configuration file `/etc/ntp.conf`:

Re: NTP socket then kernel time error

Oct 26 17:18:13 myhost ntpd[1178]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized

This seems reasonable when ntpd has just been started.

Re: NTP socket then kernel time error

The first errors suggest ntpd is started to early, check https://wiki.archlinux.org/index.php/Ne … col_daemon for alternative ways to start ntp.
