[Xquartz-dev] Mac OS X 10.11.4

[James Gamber]

Hi,

I installed XQuartz on my Mac. It works fine with the Mac X clients
provided, like xclock.

I am connecting to my cloud account on eApps.com both via the xterm and via
Mac terminal, with ssh -X. eApps is a standard Linux and Java.

On my cloud account I start a Java application with a SWING GUI. I am
getting the error about the DISPLAY variable not set. When I set a DISPLAY
variable, I get other typical Java errors, but my Java app aborts and no X
window appears on my Mac.

I am seeking a developer that will assist me to fix this for a fixed fee.

Jim Gamber

If your DISPLAY environment variable isn't set, that's the problem. Given that you're using ssh -X, it's likely that the ssh server is configured to disallow X11 forwarding.

See http://www.xquartz.org/FAQs.html, specifically the last couple lines of the section which indicate the need for 'X11Forwarding yes' in sshd_config

Hi,

I had previously done

X11Forwarding yes' in sshd_config

But that didn't change anything.

Also, is there any XClient app, like xclock, anywhere on the internet (not
on my computer) that I could access via ssh and/or XQuartz to perform a
test. That would verify my local firewall, settings, etc local issues are
not a problem.

Did you do that on the *remote server side*?

Post by James Gamber
But that didn't change anything.

If that's the case, then you're seeing a bug in ssh. What is DISPLAY set to locally when you 'ssh -X ...' to the remote system? What is it set to on the remote system?

the remote side has no x software at all. Not even an xclient like xclock. It is just a clound linux. I will ftp my mac xclock binary over to cloud and see if it will pop an x window on my xquartz on my mac when i try to run it

Regrettably, my xclock binary will not execute on the remote machine. I
don't think it likes that binary. I can run it fine from my Mac, where it
appears fine in XQuartz.

It is hard to believe that there is no test xclock or any X client app
anywhere on the internet that I can just connect to with xquartz from my
local mac and at least determine that a known x client application will
work.

Doesn't anyone know of such a test internet site.

If it doesn't exist, the X community should make one to confirm that a mac
X server, file wall, and X configuration settings are working over the
internet.

Jim Gamber

My virtual Solaris, Linux, and MS Windows machines with X11… But wait: you can have your own! Oracle VirtualBox (or some Parallels Desktop or VMware Fusion as evaluation download) plus some Oracle Solaris or Linux or MS Windows (Server) appliance (plus Cygwin or such for MS Windows). Even easier, doesn't your friend (neighbour?) have a Mac? (And where is your previous one?)

I have a mac and I dont have a friend with an xclock binary on a mac.

And you miss the point, if i have a machine where i am not certain about my config, the last thing i want is a second machine that is not known and tested as working.

this is a standard test case for any client server pair of machines, test a new xserver machine with a known remote xclient machine. The remote machine is known to work correctly.

so i expect an xclient machine/app with public access to run the xclient to be out there somewhere on the internet already someplace.

The remote machine is not known to work correctly. That's the point. Given that DISPLAY is unset on the remote and you're using ssh -X, the issue is either:
DISPLAY isn't set locally
sshd on the remote is not configured to allow X11 forwarding
ssh had issues connecting to the DISPLAY socket

That is not an appropriate tone to take with people who are trying to help you out. Your emails are full of misconceptions and we're trying to point you in the right direction.

It's not a matter of money. Most people on this list are more than willing to help you out at no cost. We've provided you with the tools to solve the problem yourself.

Post by j***@gmail.com
I am getting the error about the DISPLAY variable not set.

Thus the issue is that the remote system is either not configured correctly, or DISPLAY wasn't set correctly on the local system when you ssh'd out.

Post by j***@gmail.com
When I set a DISPLAY variable, I get other typical Java errors, but my Java app aborts and no X window appears on my Mac.

What are you setting it to? The lack of a DISPLAY envvar is a fairly strong indication that X11 forwarding is disabled and thus nothing you set DISPLAY to should be expected to work (unless you've specifically opened yourself up to insecure connections).

Thanks for the follow-up Tom. Hope you got paid well for dealing with him.

Hi,
I worked through this with James and it turned out xauth wasn't
installed on the server (Centos 6.6 x64). It needed to be installed
yum install xorg-x11-xauth.x86_64
With this done, things started to work.
This seems to be to do with CentOS not coming with xauth by default,
rather than something specific to eApps, so perhaps this will prove
useful to somebody in the future!
Thanks,

Which remembers me of a similar behaviour of RHEL, Red Hat Enterprise Linux, from which CentOS is derived.

People say that if you play Microsoft CD's backwards, you hear satanic things, but that's nothing, because if you play them forwards, they install MS Windows.
