On the node I run
python -c "import pygtk;pygtk.require('2.0');
import gtk;print(gtk.gdk.get_display())"
And I get the following.
(process:296): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/init.py:57: GtkWarning: could not open display

-c:1: GtkWarning: IA__gdk_display_get_name: assertion `GDK_IS_DISPLAY (display)' failed
Any ideas what additional setup is required to get this to work?
First error is what I get when I try and attach the xpra to the docker session.
hi @onekilo79,
Could you please connect to the container through ssh and type: ps ax to check if the docker session is really runnnig?
Hello @rogaha,
Thanks for the quick response! Here is px ax | grep docker. Have I started too many docker requests?

Hi @onekilo79,
The session seems to be started. Now, when you try to attach to it using: xpra --ssh="ssh -p port_number" attach ssh:docker@ip_number:10 it shows that error message?
Please check the xpra version of the client machine as well. Are you trying to access it from Windows, Linux or Mac?

Then it has 3 lines of entering the password for the docker user.
Permission denied, please try again.
Then
Permission denied (publickey,password).
I then tried to pass the password via the command line and got the same error without the permission denied errors.
sshpass -p 'DockerPwdFromCmdLine' xpra --ssh="ssh -p port_number" attach ssh:docker@ip_number:10
Are you accessing it from a Linux client? Can you please check its version?
vagrant client on a mac. Have had same experience on ubuntu client: 12.04 -> server: ubuntu 12.10
Client:
ubuntu: 12.04 from standard docker install.
xpra v0.0.7.36.
docker version:
Client version: 0.6.3
Go version (client): go1.1.2
Git commit (client): b0a49a3
Server version: 0.6.3
Git commit (server): b0a49a3
Go version (server): go1.1.2
Last stable version: 0.6.3
Server:
ubuntu 12.10
xpra v0.3.11
That's why. You are trying to access you virtual desktop from a virtual machine, without GUI (graphical user interface). You should access it either from your Mac or from a complete VM can be a Linux or Windows box.
Try to install xpra on your mac. Then from you terminal on Mac type: /Applications/Xpra.app/Contents/Helpers/xpra --ssh="ssh -p port_number" attach ssh:docker@ip_number:10
Make sure that you are able to access the container from you Mac. Try to connect to the container via ssh from a mac terminal.
@rogaha thanks for all your help. I will close this as I was just being a bit stupid. I need to get my vm was created with nat networking so I have to get bridged networking working.
Ok! Please let me know if you need any help!
Thanks
Wrote up 2 blog posts on the things I was having problems with but did manage to get it up and running on both os x and ubuntu 12.04.
