- In article <1h8f4bINNehh@manuel.anu.edu.au> you write:
- =>(basically because there are too many users who re-direct DECW$USER_DEFAULTS
- =>from SYS$LOGIN, so it would take too long!), I was wondering if there is a way
- =>to tell the server not to check "Security" at all, ie let all connections in,
- =>or possible have a list of "secure hosts" (like the nodes in our cluster, for
- =>crying out loud!) which can always get in regardless of the contents of the
- =>user's SMB_SECURITY file ?

- Well, you could write a small X program which could be invoked by
- the system LOGIN procedure. The X program would consist of the one or two
- calls needed to turn X security completely off.
-
- However, I would suggest that the wholesale shutdown of your X security is
- a bad idea.
-
- What X security is designed to do is to control who has access to the
- resources on the X server (e.g. Input from the mouse and keyboard, output to
- the screen). With the security turned completely off, it would be possible
- for anyone on your network to monitor the keystrokes on another workstation
- and take snapshots of screens. This is fairly easy to do, and a supported
- feature of X.
-
- Now if your workstations are running TCP/IP and connected to the Internet,
- without X security anyone could spy on your X server. Perhaps they get
- lucky and see your system password (or worse). The same problem can
- be said if you are connected to a wide area DECnet or LAT network.
-
- Turning off your X security will invite other problems. I would suggest
- that you pursue an alternate solution. I've submitted some transport
- debugging stuff to DECUS that you may find useful (Anonymous FTP to
- PUBLIC.TGV.COM), and there is a supported transport debugger in
- MultiNet (MU X11DEBUG).
