The check_ntp_peer suggestion is good, since it's a C program which speaks the NTP control protocol enough to parse out some status from remote servers, thus can report on many machines at once. You don't need to use it with Nagios. Otherwise, how about: ntpdc -c sysinfo | grep -q $'^stratum:[ \t]*[2-4]$' echo $? If the stratum is 2, 3, or 4, then exit okay, else exit error. For command-line munging, "ntpdc -c sysinfo" is helpful. -Phil _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
