Tracking DECnet Connection Source?

» close window

The Question is:

 
Is there any way to know the remote PID of a
process making a SET HOST or remote task on my
system?
 
ACCOUNTING, SHOW TERMINAL and so on report the
remote node and remote user, but a user can have
many processes or many users can use the same
account on the remote node.
 
 
 

The Answer is :

 
  If multiple users share access to a single username, there is no way to
  differentiate among the potential users, and thus no accountability.
 
  The Process ID information is not communicated over the DECnet network
  as part of the default behaviour of a DECnet connection operation.
 
  DECnet NCP (SHOW KNOWN LINK CHAR) or the NCP management interface
  (NICE) can be used to query activity, matching the local Process
  ID to the local DECnet link number and then to the remote DECnet
  link  number, and on the remote system the DECnet link number can
  be translated into the Process ID on the remote system.
 
  The OpenVMS Wizard would recommend enabling auditing on both ends of
  the connection, if this is of interest.  Alternatively, add some DCL
  or the invocation of an executable in SYLOGIN.COM and/or in a LOGINOUT
  LGI callout that performs the reverse lookup for the incoming DECnet
  connection using NICE or similar on the local and on the remote node.
