Run a script on the Linux box that periodically calls "ntpq -q localhost", then parses the output. The script should check that the line for Cisco your router begins with an asterisk in the ntpq -q output. This means your router has been selected as the synchronization source by the clock filter. If it doesn't have an asterisk, have the script do whatever alert action you want - email, syslog, etc. If you have more than one server configured in your ntpd, you will have to add some smarts to handle or ignore those as appropriate. I do not have an example script, unfortunately. -- RPM _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
