System Administration Guide: IP Services

ProcedureHow 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 terminated. This trace includes all packet transfers when you start the in.ndpd daemon.

  1. Assume the Primary Administrator role, or become superuser, on the local IPv6 node.

    The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.

  2. Start a trace of the in.ndpd daemon.


    # /usr/lib/inet/in.ndpd -t
    
  3. Terminate the trace as needed by typing Control-C.
