Yes, this was the old system. I am not an expert in ntp, but I have read carefully http://ntp.org few years ago and I return on it now and then. I can miss something... I am not the truth! On the web site http://www.ntp.org/ ->Implementation Documentation http://www.eecis.udel.edu/~mills/ntp/html/ntpdate.html said: Disclaimer: The functionality of this program is now available in the ntpd program. See the -q command line option in the ntpd - Network Time Protocol (NTP) daemon page. After a suitable period of mourning, the ntpdate program is to be retired from this distribution And http://www.eecis.udel.edu/~mills/ntp/html/ntpd.html and the man tell us: -q Exit the ntpd just after the first time the clock is set. This behavior mimics that of the ntpdate program, which is to be retired. The -g and -x options can be used with this option. Note: The kernel time discipline is disabled with this option. -g Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. See the tinker command for other options. The same options are set in the man of ntp. IMO, ntpdate should be replaced with: ntpd -gq I don't understand why ntpdate is listed as an active daemon in drakxservices. In /etc/sysconfig/ntpd : - Mageia 1 : OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid" - Mageia 2 : OPTIONS="-g" - Mageia 3 : OPTIONS="-g" Then it seems that ntpdate is no longer useful since Mageia 2. -- Pierre Jarillon - http://pjarillon.free.fr/ Vice-président de l'ABUL : http://abul.org Microsoft is for computers what McDonald is for French gastronomy
