You have exported DISPLAY variable in normal user mode as,

$ env | grep DIS
DISPLAY=9.184.42.224:0.0
$ su
Password:

Try to set in root session as,
# export DISPLAY=9.184.42.224:0.0
# echo ${DISPLAY}

has to show the setting.

# sam &

Meantime, you have to start xwindow client session. It will work.

HI,

Why dont you directly start a X window to hp7xx ?? Anyways, you can easily export your display IP in hp7xxx as

# export DISPLAY=:0.0

Now, start sam again. It should work.

/usr/bin/X11/xhost: unable to open display "9.184.42.224:0.0"

hm.. Problem is with connectivity. Do this,

# ping 9.184.42.224
# nslookup 9.184.42.224

From 9.184.42.224 machine to hp-ux machine,

# ping hp-ux machine

IS it working?

Can you show this,

# who -u

Are you able to see the ip-address of 9.184.42.224 there?

Hi Muthu

Thanks for your immediate reply. Let me explain once more how am i trying.

I am using putty ssh to connect to the hp9xxxx server. I am enabling the "X11 forwarding" in the putty. I am creating an environment by running Xmanager passive.

As you said i set the DISPLAY variable in root. But how can i start the client session after running sam.

thanks.

Hi Arun

tried exporting DISPLAY as you said. still the same error is coming.

# export DISPLAY=10.214.2.84:0.0
# echo $DISPLAY
10.214.2.84:0.0
# sam

The DISPLAY environment variable is set to "10.214.2.84:0.0", but
the current configuration won't allow sam to run on that display.

The DISPLAY environment variable may be incorrect, or, if you are
running sam remotely, you may need to allow the remote system
to access your local X server by typing

/usr/bin/X11/xhost +hp7d104

on your local machine.

Do you want to proceed using the terminal version of sam?
(yes or no) [yes]

Thanks

Yep. I guessed it.

Then you can get sam view on your first machine 9.184.* You can get sam view in step-up machine. If you want to have the view then you have to setup routing table to the machine directly. So that you can get it.

May be you can login with step-up machine with GUI based from there get the GUI of real machine. That is possible.

Re: Xwindow problem

Arunvijai_4 — Fri, 24 Feb 2006 07:48:47 GMT

Hi S.O,

The logic is simple,

1) Xmanager from PC 9.184.42.224

2) From, hp9xxxx open a telnet window to hp7xxxx

3) in hp7xxxx, do this,

# export DISPLAY=hp9xxxx:0.0

4) Execute "sam" in hp7xxxx

5) You will get a xwindow in hp9xxx

6) See the window from XManager in PC..

Hope this is clear.
