"Cannot find per display information" , when using Reflection X

[ColaBlizzard]

I am using Reflection X on a Win XP system, trying to display from a HP-UX (11.31) machine.

I have set DISPLAY to :0.0
and reflection X also seems to be running on :0.0

I have no idea what is wrong.

Exact error message:
Error: Can't open display: :0.0
Error: Couldn't find per display information

[Steven Schweda]

> Error: Can't open display: :0.0

And this "" is the IP address of
the Windows system, or what?

> and reflection X also seems to be running
> on :0.0

What, exactly, does that mean? As usual,
showing actual commands with their actual
output can be more helpful than vague
descriptions and interpretations.

I'm not a "Reflection X" user, so I know
nothing, but have you done anything on the
Windows system to run this stuff? Simply
installing it probably isn't enough.

One simple test is to use Telnet to try to
connect to the X server. (":0.0" should be
port 6000). On the HP-UX system:

telnet 6000

A complaint like "Connection refused" would
suggest that the X server is not running on
the Windows system.

An X server normally has some security
settings, so that not everyone in the whole
world can put things on your display. You
may need to grant permission for the HP-UX
system to access the X server on the Windows
system. (How to do that in "Reflection X"
is, of course, beyond my feeble knowledge.)

Reflection X is a GUI so I am unable to provide actual commands. This is the port on which Reflection X runs, out of the Box.

When I try the above I get,

Then I need help here too.

Does any other network stuff (Telnet, SSH,
FTP, ...) work between these systems?
(Normally I might ask for info on the routes,
but if you're hiding the IP addresses, I
won't bother beating my head against that
wall.)

How many firewalls are in there to block
access to this port from that system?

Why not use the X tunnel via ssh?
You don't need to set DISPLAY, the system does it for you.



Try "mobaxterm" from web, this is cool.
Run the application, ssh to your server and you are ready!

In order to clarify if this is a problem of IP communication between your server and your client (yes, in this case your Windows program is the server ...), run the above telnet command from your windows.

If a connection can be made it means that the X server is running well. Then try the same command on HP-UX. If you are unable to establish a connection, then you should check your firewall settings. You could have a firewall running on your windows station or on your HP-UX machine. Or you have a firewall somewhere along the path ...

Best regards,
Horia.

@Steven

I am able to telnet from the Windows Machine to the HP-UX machine.

There is a firewall on the Windows system.

I believe I am unable to Ping my windows system from the HP-UX box. Something on the gateway is preventing the forward of packets to my system.

I believe someone here should help me solve this in the next couple of days.

@Horia

I am able to telnet from the Windows system to the Windows system [Local-Local].
I get an empty screen though. But no connection failures.

Thank all those who helped me out. Looks like a connection issue between the two boxes.

Will reply and bump this thread if the local system admin isn't able to help me out.

Hello,

When I use Reflection X aswell as exporting my DISPLAY variable, I also export XAUTHORITY variable like this

export XAUTHORITY=/home/username/.Xauthority

Here's a couple of things I've found when having similar difficulties in the past.
1. Are you using multiple network adapters on your windows system? I've found that when I'm connected to the wireless as well as wired network, HP-UX gets confused.
2. Try putting the IP address and host name of your XP computer in the hosts file on HP-UX.

Hope this helps.

You assigned 1 point, but did you try the X tunnel?

I'm sure this will solve your problem.
