Na offline masinach se nejdrive zasynchronizuje pomoci 'ntpdate' o masinu nadefinovanou v /etc/ntp/step-tickers (viz. script /etc/init.d/ntpd) a pak jede po portu 123(tcp/udp). Jinak muze fungovat v ruznych modech (active/passive, client/server broadcast/multicast). Odchylky oproti frekvenci cmos casu si zapisuje (pokud je to nadefinovano) do 'driftfile' no a kdyz se obcas spusti hwclock -w , tak mam posychrovane i cmos-ove hodiny :-) Caha --------------------------------------------------------------------------- Meta-FAQ (odhlášení, archív, FAQ a další): http://www.linux.cz/mailing-list TIP: Hledejte pomoci Google: http://google.com/linux
