How to Trace the Activities of the IPv6 Neighbor Discovery Daemon

If you suspect a malfunction of the IPv6 in.ndpd daemon, you can start a log that traces the daemon's activity. This trace is displayed on the standard output until it is terminated. This trace includes all packet transfers when you start the in.ndpd daemon.

  1. Start a trace of the in.ndpd daemon. 
    # /usr/lib/inet/in.ndpd -t
  2. Terminate the trace as needed by pressing Control-C.
Example 1-8  Tracing the in.ndpd Daemon

The following output shows the beginning of a trace of the in.ndpd daemon.

# /usr/lib/inet/in.ndpd -t
