To trace data on a local system or a remote server, you must hold
specific rights identifiers in the rights database of the node you
are invoking CTF from. These rights identifers are:
NET$TraceHeaders - trace protocol header information on local node
NET$TraceAll - trace protocol header and data on local node
NET$TraceHeadersRemote - trace protocol header info on remote server
NET$TraceAllRemote - trace protocol header and data on remote server
The difference between NET$TraceHeaders and NET$TraceAll is that
NET$TraceAll will allow you to see the user data portion of the
protocol data unit, which may contain sensitive or private information.
These rights identifiers must be granted through the Authorize utility:
$ SET DEFAULT SYS$SYSTEM
$ RUN AUTHORIZE
$ GRANT/ID <rights_id> <username>
