Seeing that I've used ntpd for a decade and am more comfortable an familiar with it, I think I just stick with ntpd. However, we have yet *another* new control system. We are supposed to issue: $timedatectl set-ntp yes to activate your selected daemon. I just used the new systemd commands, thinking that would be enough. So I tried that and rebooted. Nope, same problem: $systemctl status ntpd ntpd.service - Network Time Service Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled) Active: inactive (dead) I have also tried: $systemctl reenable ntpd To get the symbolic links rewritten. No help. To be clear, if I manually issue: $systemctl start ntpd ntpd runs fine: $systemctl status ntpd ntpd.service - Network Time Service Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled) Active: active (running) since Sun 2015-05-24 11:39:21 PDT; 8s ago Process: 2935 ExecStart=/usr/sbin/ntpd -u ntp:ntp $OPTIONS (code=exited, status=0/SUCCESS) Main PID: 2936 (ntpd) CGroup: /system.slice/ntpd.service ââ2936 /usr/sbin/ntpd -u ntp:ntp -g May 24 11:39:21 cobalt ntpd[2936]: Listen normally on 3 enp4s0f0 10.0.0.160 UDP 123 May 24 11:39:21 cobalt ntpd[2936]: Listen normally on 4 lo ::1 UDP 123 May 24 11:39:21 cobalt ntpd[2936]: Listen normally on 5 enp4s0f0 fe80::ec4:7aff:fe34:1dcc UDP 123 May 24 11:39:21 cobalt ntpd[2936]: Listening on routing socket on fd #22 for interface updates May 24 11:39:21 cobalt ntpd[2936]: io_setbclient: Opened broadcast client on interface #3 enp4s0f0 May 24 11:39:21 cobalt ntpd[2936]: Listen normally on 6 multicast 224.0.1.1 UDP 123 May 24 11:39:21 cobalt ntpd[2936]: Joined 224.0.1.1 socket to multicast group 224.0.1.1 May 24 11:39:21 cobalt ntpd[2936]: 0.0.0.0 c016 06 restart May 24 11:39:21 cobalt ntpd[2936]: 0.0.0.0 c012 02 freq_set kernel 17.232 PPM May 24 11:39:22 cobalt ntpd[2936]: 0.0.0.0 c515 05 clock_sync It's just not running at boot time.
