We assume that the time server is available only in the local network and has the 'at least 3 external stratums' correctly (manually) set. External servers list should be dropped. WDYT ?

This occurs because ntpd stop himself if the delay between local time and server time is superior to 1000s see : http://www.eecis.udel.edu/~mills/ntp/html/debug.html to avoid this without having to change/set tinker panic, we should first ensure that ntpd is stopped ( service ntpd stop ), then launch ntpdate ( ntpdate mynewserver.com ), and finally lanch ntpd ( service ntpd start ) indeed ntpdate doesn't use the panic threshold and just sync the time with the server time. So this way we are sure that ntpd will be running fine afterwards --- Il faut rire avant d'etre heureux, de peur de mourir sans avoir ri. -- Jean de La Bruyere, Les Caracteres
