The Question is:
why do i receive this message upon entering
the command ... $show intrusion
The Answer is :
Probably because the security server has been disabled?
Some sites chose not to start the security server, and (if following
the documentation) have also set the appropriate flags (bits 4 and 5,
most commonly) within the SECURITY_POLICY system parameter that allow
OpenVMS to operate without the security server active.
The following command can be used to start the security server:
$ @SYS$SYSTEM:STARTUP SECURITY_SERVER
From HELP/MESSAGE SERVERNOTACTIVE:
SERVERNOTACTIVE, security server is not active
Facility: SECSRV, Security Server
Explanation: A request was made of the security server but the server is
not currently running.
User Action: Start the security server and retry the request.
