     disableXhost - utility for	disabling remote access	to local display

SYNOPSIS    [Toc]    [Back]

     /usr/lib/desktop/disableXhost

DESCRIPTION    [Toc]    [Back]

     The disableXhost utility is used to prevent remote	hosts from placing
     windows on	or otherwise getting access to the local display during	a
     user's login session.  All	remote hosts will have display access
     disabled, whether access originally was granted implicitly	(ex., using
     xhost +) or explicitly (ex., using	xhost +	hostname).  Remote toolchests
     will no longer be able to post windows on the local display; however,
     remote iconviews (dirviews) will be able to continue displaying and
     spawning child iconviews.


     This utility is invoked when the user selects System > Disable Remote
     Display from the toolchest.  It is	not intended to	be run directly	by the
     end user.


     In	the IRIX Interactive Desktop (IID), there are four different ways to
     control display access:


     Permanent Methods:

	 1) Through the	Improve	System Security	task in	the System Manager

	 2) From the Desktop toolchest > Customize > Desktop, on
	    the	Enable Remote Display toggle button


     Temporary Methods:

	 3) Indirectly from the	Desktop	toolchest, from	Access Files then
	    As Another User or By Remote Login

	 4) From the System toolchest >	Utilities > Enable Remote
	    Display or Disable Remote Display


     Permanent settings	are remembered and restored between login sessions.
     Temporary settings	override the permanent settings	during the current
     session, lasting only until the user logs out.

     Method 1 lets you enable or disable display access	for the	whole system
     for new users -- that is, users whose accounts are	created	through	the
     IRIX 6.3, 6.4, and	6.5 system administration User Manager after the
     Improve System Security task is run.  If users have their own xhost(1)
     setting in	their own customized dotfiles, then their settings there will
     override the setting made in method 1.


     Method 2 enables or disables display access immediately when you change
     the Enable	Remote Display toggle, but its effects last permanently,
     across login sessions.  Methods 3 and 4 can override this setting,	but
     the overriding effect lasts only during the current session.


     Method 3 enables display access for a specific host whose toolchest or
     dirview the user wants to view.  The access is enabled automatically for
     the specified host.  This setting lasts only for the current session.


     Method 4 enables or disables display access immediately and its effects
     last temporarily, only during the current login session.  It can override
     settings made through any other method, but the overriding	effect lasts
     only during the current session.


     For more information about	the entire IRIX	Interactive Desktop
     environment, see the IID(1) man page.

NOTES    [Toc]    [Back]

     There is an ambiguity in that the Desktop panel does not show the current
     display access status but instead shows the user's	default	preference.
     In	6.5, the user can be assured that they are disabling all remote	access
     either by unchecking the Desktop panel's Enable Remote Display toggle or
     by	selecting System > Disable Remote Display.
