I would like to have a one-liner for updating the date via NTP getting the NTP-servers from the /etc/ntp.conf file. Especially because a manual command does not always work, because of firewall rules, not all servers in /etc/ntpd.conf being reachable.service ntpd stop, ntpdate ntp1host, service ntpd start This would be the normal way to go. Is there a command that will allow me to force-update time via NTP without shutting down the daemon?
