Running xclock - Setting the Display in Linux

[bonson mampilli]

Hello,

I am trying to get xclock to display on my Windows XP machine so that I can then move to installation of another application. However, I have been stuck since a very long time now.

I have also set the server IP address in the X0 hosts file on my Windows machine. So the file now reads:
localhost
<Server IP>

I have installed Xming on my Windows machine. So the steps I do are as follows:

1. Start xMing.
2. Start xLaunch.
2a. Select Multiple Windows. Click Next.
2b. Start No Client. Click Next.
2c. Clipboard is checked. Click Next.
2d. Click Finish
3. can see the Xmin Server icon in my taskbar.
4. Now I start putty
4a. Give the host name as "myhostname.com "
4b. The port by default is 22
4c. SSH radio button is selected
4d. Close Window on Clean exit is selected
4e. Click Open
5. Command prompt
6. login as : I enter "root"
7. Enter password
8. I see the last login details and then I see
root@server [~]#
9. Which shell am I using:
root@server [~]# echo $SHELL
/bin/bash
10. Then I run the following commands
root@server [~]# DISPLAY=<my ip>:0.0
root@server [~]# export DISPLAY
root@server [~]# echo $DISPLAY
<my ip>:0.0
root@server [~]# xclock
Error: Can't open display: <my ip>:0.0
11. I ran the xhost command:
root@server [~]# xhost +
xhost: unable to open display: <my ip>:0.0

Totally stuck now. Dont know what to do.

If there is some other freeware software that I should use other than Xming, then please let me know that also.

Under Connection->SSH->X11 branch select "Enable X11 forwarding"

Hello,

Thank you very much for the response. Now the error "xhost: unable to open display: <my ip>:0.0" is not coming. :o)

However, I xclock is not poping up. :o(

Just wanted to confirm the following configuration:
Under Connection->SSH->X11 branch the following are the settings:
Enable XX1 forwarding (Checked)
X Display Location (Blank)

Remote X11 authentication protocol
- MIT-Magic-Cookie-1 (Selected)
- XDM-Authorization-1 (Unselected)
x Authority file for local display (Blank)

Is this correct? Do I need to do anything else?

Thanks again for responding

Regards
Bonson

Just to add.. after waiting for 15 minutes or so.. now xclock has returned the error "Error: Can't open display: <my ip>:0.0"

are you sure you have to set the DISPLAY variable on the server? my experience with windows is a bit dusty but sitting at my linux desktop i only do

joe@desktop:~$ ssh -Y user@server
[user@server ~] $ echo $DISPLAY 
localhost:22.0
[user@server ~] $ xclock

and it works fine. every time i do this i get a different DISPLAY number so i guess ssh (or putty in your case) is taking care of this.

can you forward the xclock from one unix box to another?
does the x server work locally? have you tried as non-root? maybe there are some extra restrictions regarding x11/port forwarding for root?

I had this same problem. Went crazy looking for solution.

What is the icon for a sheepish grin? In my case, I simply had to activate MING before launching Putty. I had been under the impression that Putty would automatically activate MING. This is not the case.

Hope this helps some other poor schmucks.
