RE: Strange xhost behavior- Please help!!

["Dawson, David W" <david dot w dot dawson at lmco dot com>]

The problem is a "feeture" of all X-servers:

When the X-server detects that the last client connection terminates, the
server does a full reset.

xhost is NOT a persistent connection.
As soon as the xhost program completes it's job (telling the X-Server host
to change the permissions), the xhost program closes it's connection with
the X-server.  Since (in your case) it is the ONLY connection at that time,
the X-server resets and promptly eradicates the xhost setting.

You need to open a persistent connection first: an xterm, a window manager,
xclock, something....

Hi!

I have the following problem:
- I have started a bash consol window as usual with "cygwin.bat"
$>  XWin.exe &
$> export DISPLAY=127.0.0.1:0.0
$> xhost +

Then from another host:
[einstein]$ export DISPLAY=127.0.0.1:0.0
[einstein]$ xterm &
Xlib: connection to "127.0.01:0.0" refused by server
Xlib: No protocol specified

Then at the original host:
$> xterm &
# The window was accepted and displayed

Second try from einstein:
[einstein]$ xterm &
Xlib: connection to "127.0.01:0.0" refused by server
Xlib: No protocol specified

Then at the original host:
$> xhost +


Third try from einstein:
[einstein]$ xterm &
# The window was accepted and displayed

So, the X server first needs an xterm from the original host, only
after that will accept connection from another hosts. I have found, that
the second "xhost +" works from the in the X server previously
displayed xterm too.

Why is this so? Why the first "xhost +" does not work?
Can anybody help me? (I  have the latest X server:4.2.0-1).

Thanks,
