Usage Guidelines

Usage Scenario

The Kiss-o'-Death (KOD) is a brand new access control technology put forward by NTPv4, and the KOD is mainly used for a server to provide information, such as a status report and access control, for a client. After the KOD function is enabled on the server, the server sends the kiss code DENY or RATE to the client according to the operating status of the system.

When the kiss code is generated in a specific situation, run the ntp-service kod-enable command.

Follow-up Procedure

After the KOD function is enabled on the server, you can run the ntp-service access limited command to enable control on the rate of incoming NTP packets. When the rate of incoming NTP packets reaches the upper threshold, the server sends the kiss code.
