Re: [X2go-dev] Extra functions requested in x2go

Hi list, Thanks for the replies. They are helpful. To explain a little further: We have a Linux application written in wxPython with Postgresql and (mostly) Windows clients. Goglobal gives us the possibility to export a file to the client and subsequently start the file. The mime type of the file determines which program is started on the client. In the client a trigger should start the application with the file that is passed. -----Oorspronkelijk bericht----- Van: Paul van der Vlis <paul(a)vandervlis.nl> Verzonden: za 19-06-10 22:14:25 Aan: x2go-dev(a)lists.berlios.de; Onderwerp: Re: [X2go-dev] Extra functions requested in x2go Dick Kniep schreef: > Hi List, > > First of all,I am very impressed by the work you have done and would > like to thank all involved. > > We are a company that provides a kind of CRM system over the net to our > customers.

I know GoGlobal but I don't understand your question completely. Are you talking about a Windows client what shows a Linux application?

But I wonder this is a problem, maybe you can tell a bit more about it. Normally you can do this kind of things with a .desktop-file in /usr/share/applications. There are some problems with the latest openoffice from backports, this command will help: update-desktop-database /usr/share/applications This is not X2go related.

Hi List, Well, actually it is not that difficult to export from the server to the client. In fact, as the user directory is mounted and the user is logged on to the server and is executing our system, it is quite easy. From our system we write the file to the mounted directory and voila it is on the client. No problems with authorization either, because the user himself is writing to the mounted directory. The next part is trickier. If we want to start the application on the client we should have a command in x2go so that it signals the x2goclient to start the specific file. So no polling, but simply an extra command that is called on the server and sends a message to the client. Now this means a change in the client, and a protocol for the message that is used. Furthermore a command on the server should be there to signal the start of the program on the client. This could be something like "x2gorunclient path-to-the-file" Added is a drawing of the different parts of the extension. I hope it clears any misunderstanding of what I want. The yellow marked boxes are to be changed, so the x2gorunclient command is to be created and the client has to be changed so it will understand the signal of the x2gorunclient command, interpret it and start the file.

So your application runs on a a Linux X2Go Server. The user clicks the icon on their desktop and launches an X2Go Client which presents your application as a window on their physical desktop. You then want your application to be able to copy an excel spreadsheet to the physical computer where it will automatically open using whatever application on the physical computer is associated with the mime-type. Is that correct? If so, I'd imagine there is a way but it might be a little tricky. The full client (as opposed to the Firefox plugin I've been testing) allows one to automount local shares. I suppose one could do this to a consistent place (that might present some cross platform difficulties). I'm not sure how one would automate the process of copying to that local share mounted in /tmp/<uid_media which is soft links to ~/media. I'm also not sure if there will be permissions issues trying to copy to the physical computer unless the copy is done as the user. I'm also not sure how one would get it to auto-open upon copy. I suppose one could write some sort of script to poll the directory where the files are stored. Certainly getting out of my depth now! Hope this helps at least a little bit - John _______________________________________________ X2go-dev mailing list X2go-dev(a)lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev !DSPAM:4c20a76d290751343511188!

Hi LIst, A little more explanation. We publish our application from Linux, but NO desktop. So the user double-clicks an icon on his desktop and the application starts in its own window powered by x2go (currently GoGlobal). So for the user it is simply an application on his own windows/mac/linux desktop. In our application there is a menu option to export a list to Excel. So I would like to be able to do several things from our application: 1. Copy the file to the shared directory of the client 2. Start that file (based on the mime type) on the client I hope this clears things up. -----Oorspronkelijk bericht----- Van: John A.

Obviously there is a reason but, for example, why would you call X2Go rather than Excel or OOCalc to open a spreadsheet? Is it because the client is very limited and so, in effect, you want to do application publishing?

screen saver extension

Hi, I searched the web and mailing list archives, but didn't find an answer to my question: Is it possible to start x2go with the X11 screen saver extension enabled? I'd need it to get X11 idle time on the command line. Thanks, Roland

authentification cookie error
by Guillaume LUDWIG 21 Jun '10

21 Jun '10

Hi, I have a problem with my test server. Three days ago I was unable to connect to my computer with X2GO (in local connexion). Remove my .Xauthority file solved the problem. Now I'm in front of the same problem again, but there is no .Xauthority file. I'm unable to connect to my computer in local : gml@black-cerisier:~$ cat /home/gml/.x2go/S- test-50-1277062230_stDGNOME_dp24/sessions Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. gml@black-cerisier:~$ But when I try to connect from another computer, it works like a charm. (my X2GO server is on a Ubuntu 10.04) Any idea on how to solve this ? Regards, gml PS to Heinz : I have tried the firefox plugin, it works _perfectly_, great job !

No contents file for amd64?
by Jo-Erlend Schinstad 21 Jun '10

I was looking for the "x2gosuspend-session-gnome" command, so I installed apt-file and updated it, but then I received an error message: Ignoring source without Contents File: http://apt-mirror/x2go/dists/lenny/Contents-amd64.gz Obviously, apt-mirror is my local mirror. I've had no other problems with it. Thanks, Jo-Erlend Schinstad

How do users suspend their sessions?
by Jo-Erlend Schinstad 21 Jun '10

21 Jun '10

I guess the subject sais it all. I'd like to be able to disconnect from the sessions without logging out of the system. How is this accomplished using x2go? Thanks, Jo-Erlend Schinstad
