Hi, we moved a server today and DNS entries may not be synced yet, or  
maybe we have a configuration error on thenewserver. Will check asap,  
thx!

If I'm not wrong this is a message from an X tool (xhost, or maybe the VNC
server). It shouldn't prevent the OVD to work.

The fix is to probably have the keys imported into your machine. But
what is the keyserver that i need to connect to

cat key.asc | sudo apt-key add -

In the above commands, what would be the keyserver.

Hi Prabhu,

You can wget this package and install it on the host system:
http://archive.ulteo.com/ulteo/ovd/pool/main/u/ulteo-keyring/ulteo-keyring_20090729_all.deb

Run apt-get update after the installation.

Message-ID: <f13b62210909021037p6e14a406u32cc6ac02f11f4ac@mail.gmail.com>

I have a unique situation where all users need to share a common
process in Ulteo.

This is just a java application and this is shared among different
users. So i need to invoke it as a process run by another user. In
this way , we save resources and achieve sharing..

For example, user1 should be able to log into his own session and he
should be able to start a process as another user or as root
Similarly, user2 should be able to log into his own session and he
should be able to start a process as another user or as root

I currently start this java application in Ulteo xinitrc file just
before the xfce-session

How do we achieve this user switch and running the application.

Thanks & Regards,
Prabhu

As a follow up to the mail and to make it clear, I want to start a
java application as a root user across each user session. Would this
be possible?

I currently launch my application in the /etc/xdg/utleo/xinitrc file.
But the process starts as the ulteo user login. I want to run it as a
super root user or a common user

Does RSBAC and the jailing process also affect this.

Message-ID: <f13b62210909031443k6ea8f9a7s8e7fd98d70680356@mail.gmail.com>

I found out the answer to yesterday solution to run it as another user
and used su -s in the startsession file.

I am actually trying to connect to a socket through a java application
and this application is able to do this in my localmachine. But
somehow when i run the program in Ulteo the program does not connect
to the socket.

Cannot processes started in the xinitrc script in Ulteo connect to
sockets of already running processes?  Is this because of any process
jailing and segregation issue that is achieved by jailing the process.

Any pointers here would be very helpful

Do you run an RSBAC kernel? If so that might be the problem.

If not, connecting to the socket shouldn't be a problem. There's no jail, all
tha applications from the session are run in the same environment without
isolation of process.

Maybe you use a CIFS mounts for the home directory? That may be a problem...

Thank you very much Gauvain for the detailed response. I had one more

How do I know that rsbac module is active in my kernel? Do i have to run a
lsmod to find out RS_BAC is active. How do I disable this? Do I simply run a
kernel without RSBAC

And on another note. And the socket uses a TCP/IP .  I also saw another
configuration in the xfce-session file which says  disable tcp=true
/etc/xdg/xfce4-session/xfce4-session.rc

[General]
SessionName=Default
SessionName[de]=Standard
SessionName[ja]=??~Y??~V
PromptOnLogout=false

# Disable management of remote clients by default. The user
# has to explicitly enable this for security reasons.
DisableTcp=True
Is this only for incoming connections or also for outgoing socket
connections

I got the answer to some of my Queries.
DisableTcp=true prevents remote clients from using the display. Thanks for
this.

Is there a way for an application to be displayed on all vnc screens that
are accessed through ulteo via browser.

For example , say that  I want to start xeyes.

All users connecting via ulteo  user sessions should be able to see the same
 xeyes. There will only be a single instance of the xeyes running but all
the users will be able to see xeyes. I know that each vncserver created
during an ulteo session has a display 5900 + number. But would it be
possible to broadcast the same application over all the vnc server
connections.

Using this you could run common applications like xclock to all users
without running separate processes which would help in saving memory.

Thanks again. I was trying to minimize the process that could be run freeing
the application server.

Prabh

Do you mean disabling this option on tightvncverser? what's your goal here?

Regarding xeyes and many other applications, I'm not sure that users
actually want that :) I mean: xeyes is following the mouse arrow of the
user who launched it. So if other users get the same xeyes instance,
either it's going to be a big mess because xeyes is trying to follow all
the user's arrows, or all users but one are going to see xeyes follow
one (other) user's mouse arrow.

I agree that on some particular programs, xclock, or even screensavers,
that could be interesting, but it's very problematic because users can
set preferences on their own instance, those preferences couldn't be
shared.

With the "share desktop" feature on the OVD, you can even have the same
desktop for all the users, but I'm afraid there is a fundamental end
user experience issue by doing that :)

Gael,
Thank you very much for the detailed reply.

My ulitmate goal is to actually run openoffice in a listening mode. The
xeyes was just an example and i agree the same instance would be shared.

We are looking at java applications that embed openoffice and where we can
develop functionalities. We are looking at running openofifce in a listen
socket mode and to be able to support a graphical interface remotely. The
problem is that the openoffice instance we run and the launched ulteo
sessions have to share the same display aka have access to draw on the
display. Then theoretically each user can have  a java application where
openoffice is embedded. There is just a single openoffice process which runs
in a listen mode.

I am not sure whether this is implementable at all. But if it is, there is
just a single open office process, there would be no invidual openoffice
processes. The response, resource saving by way of reduced RAM consumption
and other factors would be great.

First of all, I know that each vncsession creates its own display
parameter.

The problem is I do not know whether it is possible to run a openoffice
process which is able to access the display of all launched Ulteo sessions.
I know that it can be done with one vnc seerver session.

Manually export the DISPLAY parameter to the VNCserver display and then
allow it to xhost to the client. The Disabletcp=false is so that the login
session could be remotely managed.

I do not even know whether it is possible to launch a single xapplication to
run across many vncserver sessions which may not have launched also but that
is the final goal here.  As i said above, I can get the setup working for
maybe a single VNC server session that has alread launched.

This would create an option like Zoho, Google docs for people who want to
work with Ulteo.

`grep RSBAC /boot/config-$(uname -r)` should return something if you have an
RSBAC kernel (this is not the default kernel in any distro, on we won't support
it in the 2.0 release anyway).

To be honnest I don't know what this is used for, but I doubt it's related to
the problems you're having.

Thank you for the warning.

I've discovered this 2 days ago in fact, so debian packages are currently
building using the Debian ones. We'll most likely include OOo 3.1 in the default
tarball application for the next release.
