1710.0. "Need a serial line security device" by CENPCS::BIRMINGHAM (Transporter Room - 1 to beam up...) Sun Nov 20 1994 19:34

    I have a customer who is using the DS90M and a MUXserver 380 acting as a
    TELNET/LAT Gayeway to provide connectivity from remote locations to a
    OpenVMS CLuster over both a Token-Ring and Frame Relay backbone. The
    Cluster and the MUX380's are on the Ethernet backbone, the routers are
    Cisco. A remote DS90M user TELNETs to the Muxserver 380 at the Port 
    number assigned for the Cluster alias, and get a load-balanced LAT 
    connection into the cluster. The connections work just fine. 
    
    The customer has certain locations that are secured in a locked room,
    and the application is set up to grant certain privileges based on the
    terminal's location. The problem we have is that when we come to the
    Cluster using TELNET ( the Cluster also runs TCP/IP Services for VMS ), 
    the result of a SHOW TERM ( or F$GETDVI("tt:","TT_ACCPORNAM') ) shows 
    the IP address of the DS90M but does not indicate the port name. We 
    understand that the TELNET protocol is not capable of providing this 
    the way a LAT connection does. When the same user TELNETs to the
    MUXserver at the Cluster Alias port number and gets the LAT connection,
    the SHOW TERMINAL and the Lexical function show 'MUXSERVER/TELNET_x' as
    the port name. TENLET_x doesn't indicate either the server port name or 
    the IP address of the original user. 
    
    The customer will not accept setting the VT420's Answerback to the
    location code and locking out setup, or using a ROM answerback device 
    on the printer port. What we need is a way to determine the terminal's
    location, either by query from the Cluster in a programmatic fashion,
    or by using am answerback device physically connected into the wiring
    at the terminal that cannot be removed.
    
    Can ayone suggest a way that we can create a secure identity mechanism
    for terminals connected in the fashion I have described ? Any
    suggestions, pointers, or names of companies producing a serial
    answerback device will be greatly appreciated.

Try the TOOK::TERMINAL_SERVERS conference.
