Running SunOS 4.1.1 with OW2.0
Using the default openwin script to start up X server
The problem: I can't see how to tell the server that the display I want
is `hostname`:0.0 instead of :0.0 If I want to run something
like emacs from the menus, I get a console message stating
> XNeWS Network security violation
> Rejected connection from: raven
> Client is not authorized to connect to server
It is obviously the DISPLAY variable. The openwin script
is set up to only allow :0.0 and will barf if you (ie, me)
try to play with it.
I tried setting it in .openwin-init but it seems to have no
effect at all.
Thanks for any help...And I know, this should be in a FAQ, but as of yet,
I don't believe there is one for C.W.O-L *8-) SUN - Care to volunteer
any staff members???? (* grin *) Didn't think so...

The problem: I can't see how to tell the server that the display I want

A quick glance through the openwin script shows that it doesn't like any
display specification that doesn't begin with a colon. If Emacs is trying
to open `hostname`:0.0 when your DISPLAY environment variable is :0.0,
Emacs is broken. (I use Emacs in an xterm, so I can't tell exactly what's
wrong.) Are you sure Emacs is linked with the R4 libraries, so that it can
pick up the authorization data correctly?
Probably the easiest way to get Emacs working, if you're not overly
concerned about security, is to do an 'xhost +`hostname`' before you start
emacs. (You could then do an 'xhost -`hostname`' after it had started.)
Alternatively, you could have the OW 2.0 server start up with authorization
turned off (via the -noauth option to openwin).

The openwin script The overwhelming response I got was to use the -noauth option upon startup. This to me seems like a real bad work around of some problem. The DISPLAY variable *should* be set to `hostname`:0 from my understanding; however, openwin insists that it be :0.0 I mentioned above that if I run emacs from the menu bindings without the -noauth option, it can't connect. The same is true if I try to run it from an xterm....can't connect until I set the DISPLAY to `hostname`:0 I am only dealing with the terminal that I am on. I am not trying to have remote computers pop things up on my screen; I just want the things that *should* show up on the terminal show up. I would like to have Xdm running openwin, and could set it up right now, but I will continue with Xsun until I am told of a way to get around the -noauth problem.

We have a version of emacs that was built using the X11R3 libraries. It exhibits the same symptom. xhost +`hostname` is the work-around we have used. -- Bruce G. Barnett uunet!crdgw1!barnett

One last time.....*8-)
(* smile *) Here, let me make the situation completely clear and then
something might be solved....
On the console (a 4/xxx) of raven.bu.edu I want to login in and start
up OpenWindows. I don't specify any DISPLAY variable in my .login or
.cshrc files as I might be on a simple vt220 (as I am now *8-) )
Once I login and kill of XDM and Xsun (the default Xserver) I can
log in again and run openwin by typing
my-prompt % openwin
Once it is up and running, I do
% echo $DISPLAY
:0.0
% xhost
raven.bu.edu
% emacs &
XNeWS Network security violation
Rejected connection from: raven
Client is not authorized to connect to server
[...The above is being sent to my console xterm (ie xterm -C &)]
% setenv DISPLAY `hostname`:0.0
[...ie setenv DISPLAY raven:0.0]
% emacs &
That works just fine *AND* all other applications including all from
the $OPENWINHOME/bin directory. That is all work from *that* xterm
only.
