But I discover that it works from time to time: some days just once, some days 5-6 times a day I receive e-mail with text like 12 Mar 12:05:05 ntpdate[25368]: no server suitable for synchronization found But if I log in to server and run # /usr/sbin/ntpdate ru.pool.ntp.org everything always works OK: it says 12 Mar 13:51:57 ntpdate[27256]: adjust time server 80.93.56.210 offset -0.616000 sec Maybe NTP server doesn't like when some client (my server) asks it such way - once a hour in same minute - and blocks my queries? Any suggestions?
