Xhost

Faizer — Tue, 16 Dec 2003 12:18:09 GMT

I have a HP server running HPUX11.11. Oracle's Business Intelligence requires an X session on the server.
I use xreflection on one of my PC to connect to the HP Unix server using telnet. When I get the connection to the HP server,
Then I set the DISPLAY=aaa.bb.c.d:0.0
Then I do an echo $DISPLAY.
I get the correct display seeting as above.
When I run xhost + I get the following error.
xhost: unable to open display aaa.bb.c.d:0.0

How can this problem be resolved as we need to have an xsession running all the time on the server so that the Oracle Applkication can work.

You should add the Server to the "Host Access Control List"(but that's just what it's called in Exceed. Then it should work.

Instead of connecting the server using telnet use telnet with xterm or XDMCP Broadcast.

is it a direct connection or there are firewalls between ?

Usually, with oracle, you must install a virtual frame buffer or vnc, to simulate the graphics card.

Look in this site for "vnc" or "xfb"

The command "xhost +" can only be run from the console. You will not be allowed to run it over a network connection, for obvious security reasons. And generally, it's not good to do "xhost +", but if its a "secure" network, I guess it fine.

Hi Faizer,

Make connection with your unix box
First you have to use this command:
xhost + or xhost +namemachine
With this command you give permission to use your display for output.
Go to the UNIX box en typ
DISPLAY=aaa.bb.c.d:0.0 ( ip adres van je pc)
Go back to your pc and make connection with your unix box.
Typ xload &
You should see xload screen on your pc.

Succes

P.S just use linux
You don't have to buy xreflection and it is very easy to use and it works always

I have checked the vnc sites and they do not speak for HP UX11.11. In addition there aren'nt any proven and tested scripts available. In addition we have to compile.

I tried what Idriz has said again I get the following error.:::
Cant open diaply
could not find per display information.

a ps -ef | grep for X11 shows the following
root 13828 1 0 21:23:39 ? 0:00 /usr/bin/X11/hpterm -fn 6x13 -sb
-ls -display ddd.bb.c.xx:0 This is of my pc ip

Hi,

have you thought about using "xauth(1)" to grant permission to your screen?

FWIW,
