xterm from linux to hp is not working.

[Sachin Patel]

Hi All,
I am trying to open xterm windows to local HP workstation. All system is 11.00. 712. It works only for two Workstation. So the problem is on HP-UX side. I can open dtterm windows from another HP systems without problem.

1. Telnet to linux system from 712.
2. set display = ip or name
3. run xterm and I received errors
Xlib:connection to "ceres:0.0" refused by server
Xlib Client is not autorized to connect to server
Xlib Xt error: can't open display
(It works on other systems so i thought it might be permission on local system)

Then I run on local system.
#local> xhost + (error again)
Xlib: connection to "ceres:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key

I try running xauth program and choose list it display something.

Help me Experts.

it sounds like the user running xhost isn't the same user that started the X daemon. Check who the owner of the X process is with the ps command. (ie: ps -ef | grep X) My guess is that X is running as root, and you aren't when you run the "xhost +", or something like that. When you get the xhost command working, the xterm (dtterm or whatever) will work.

Good luck!

I think this is user based Xaccess not host based so your reference at Xauth was correct.

What you need to do

Extract the cookie on the hp system from the
$HOME/.Xauthority file

# xauth extract /tmp/auth4 hp_system:0

Transfer the file with the cookie to linux system

On linux system, merge the cookie for hp_system:0
into $HOME/.Xauthority:

linux>xauth merge /tmp/auth4
linux>xauth list

both systems should be listed : also see man Xauth

or this may work -> disable Xauth under CDE by editting : /etc/dt/config/Xconfig wrt Dtlogin*authorise : False nb you may need to copy this file from /usr/dt/config.

For the change to take effect you will need to restart the Xserver. currently ps -ef ? grep X on the hp probably comes back with a -auth string ? If yes the above will disable this.

Hi
1. I run Xauth and xhost + as root.

Hi Alex,
I do not have .Xautority file in /home/. My home for users are nfs mount. same home area same account works on one HP (712) system.

I do not have .Xautority at /home/ on linux system either.

The LINUX Xterm does not support external lookups for display/DISPLAY, nor does it support a -d option! You must specify "-display hostname:X" when issuing the xterm command to have it launch to a different display!

I.E.
xterm -display myhost:0 &

Hi Sachin,

Are you logged in your HP workstation as a user or root?
If logged in as user then issue xhost+ as that user.
Also are you able to export the DISPLAY from other HP workstations to this workstation?
Is the $DISPLAY on the linux box pointing to your HP workstation when you are logged in to you linux machine (check export -p|grep DISPLAY or echo $DISPLAY).

Can you export the DISPLAY from the linux machine to any other workstation?

Appologies for not replying sooner .... busy yesterday pm :(

Did you try my suggestion on /etc/dt/config/Xconfig at all on the HP systems ?

I'd also make 100 % certain hostname resolution works both forwards and backwards on all hosts involved.

xhost +
should not give an error on the local box..

Have you tried any other applications such as xclock?
Do you have the X ports 6000/60001 blocked?

Try running xscope to determined and xlib errors..

Thanks Friends,
Alex I spoke too early. I add MIT-MAGIC-COOKIE from HP to Linux system and reboot the HP system. I didn't reboot the system yesterday. Now it is working fine.

Hi Bill. I like that site. xhost + should not generate error but it was I don't know why? Now it is not generating error.

As I said there are 2 types of Xauthority : host based as in xhost, user based as in .Xauth ... they are separate mechanisms .....
