1003.0. "Ultrix workstation session security" by DECWET::ERCOLANO (Tony's Front-end Shop) Thu Jun 22 1989 11:51

    I am running Ultrix 3.0 on my workstation.
    
    I would like to set things up so that only certain users
    can display to my workstation.
    
    Currently I do a 
    
    xhost +node-name
    
    which allows any user on system node-name to display to
    my workstation.
    
    I am particularly interested in the question of other ultrix
    nodes displaying to my workstation.
    
    For example, assume that node fungus is an 8800 running Ultrix.
    I normally do a do a rsh (remote shell) to fungus to start
    a dxterm on fungus which displays back to my workstation.
    The -display switch given to the dxterm is -display blito3:0
    (blito3 is my workstation).
    
    I have tried in the past to use the security menu from the
    session manager without much luck.
    
    Is there something that I can add to my .Xdefaults that
    would only allow certain users from other ultrix machines
    to display on my workstation?  I can recall seeing (but
    not where I saw) something about a combination of node
    name and uid (i.e. fungus:123). (I am aware that my own
    additions to .Xdefaults is not very "supportable".)
    
    I have done both a directory search and a keyword search
    of this conference without finding anything that addresses
    this particular topic.  If there is such a note please
    point me to it.
