Joerg I agree with John in his view of Hienz and Alex. They are good folks BUT everyone has to remember they are ONLY 2 people ! They have a separate life where they have to earn money to support themselves & families too. x2go is something they have dedicated themselves to because it aids them in their other income related activities. There's an old saying: Nothings impossible for those that don't do the work. Given that Heinz and Alex have been working for the past year to create this new release of x2go ... again while working on their day jobs ... oh, and while building the new x2go wiki etc. Now that they are in what is hoped to be the final stages and frankly I'd rather they focus on that and worry about where to post the source code when they have some breathing space. Give them a break is my vote. Brian Mullan ------------------------------ > > Message: 3 > Date: Wed, 22 Sep 2010 14:51:42 -0400 > From: "John A.

Resume specific session with x2goplugin
by contact＠gmli.fr 22 Sep '10

22 Sep '10

Hi, (first of all, thanks for your help Heinz and Sven) I would like to know if it's possible to resume a specific session with the plugin ? The goal is to list sessions (with x2golistsessions) on the server, and paste the session id in the x2go.server file in order to resume it. I don't want to use the resuming form showed by the plugin (my users are confused with it). I'm making a webapp, and I would list sessions in a web page, and make it possible to resume paused sessions just by clicking on a link. Thanks in advance ! Regards, Guillaume

headless client with pyx2go
by Dick Kniep 22 Sep '10

22 Sep '10

Hi list, We want to develop a headless client in python using pyx2go. The application should have the following features: 1. All parameters except for the password should come from a profile stored in the users home directory 2. The user should have the possibility to enter the password, the username and the server, where the username and the server should be retrieved from the profile 3. The client should support clientside printing as the x2go client 4. The home directory (or another directory) on the clientside should be mounted with fuse on the serverside 5. The client should start XMing with all appropriate parameters 6. It should be possible to start an application from the server side by starting a file. So if a file called test.doc exists and that file is started, MS-Word should start. 7. The profile should be maintained by a separate program (nice gui application) We've got the demo.py running. However when it ends, the session is terminated correctly, but a thread remains active. Probably the thread should be joined with the mainprogram. Could anyone help us with documentation on the use of fuse and the way commands are passed from client to server vice-versa? Dick Kniep Lindix BV tel. 036-5215580 mob. 06-50991858

a2go-client for MAC
by Jarle Bjørgeengen 21 Sep '10

21 Sep '10

Hi, first, thank you for a nice application. I've been looking for a suitable free NX low-bandwidth solution and x2go seems to fit the purpose well. I'm using the MAC client, and I'm a bit puzzled that it is necessary to turn on remote connections (and hence open the X11 TCP port for listening) in order to locally display the desktop received over NX protocole (presumably tunneled over SSH) . So first you tunnel over SSH for security, and then it is required to open a potentially vulnerable service in order to display that picture ... ? When starting X programs (like XTERM) in OSX it seems that the default behavior is to communicate over a internal unix socket. Would it be possible to have x2goclient for mac using the same mechanism rather requiring the opening of unsafe services ? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Best regards .~.

FYI: New community distro born
by Oliver Burger 19 Sep '10

19 Sep '10

Perhaps most of you already heard about the problems in which Mandriva has steered itself. Now I'm happy to announce, that out of the ashes of a dying Mandriva a new distro is born. Mageia is a community project without a commercial company involved. As packager of the German mandriva community I was building the x2go packages for Mandriva in the past and I will be building x2go packages for Mageia in the future.

Plugin updates over time
by Gerry Reno 17 Sep '10

17 Sep '10

What will be the policy regarding Plugin Updates over time? By that I mean will future versions of the plugin retain backward compatibility and work with existing installations of x2go? It seems the browsers are always pushing users to upgrade their plugins so they have the latest functionality and security fixes. But this can also mean that existing installations that work with the newer plugin versions could also need updating as well unless the plugin is always sure to be backward compatible. What is the x2go policy in regard to plugin updates and backward compatibility? Regards, Gerry

Plugin Sources?!
by Joerg Sawatzki 15 Sep '10

15 Sep '10

Hey, I know this question was on the list already a couple of months ago but I cannot find it anymore.... So once again: Where is the source of the browser plugin? And where's the source of the win32 client? I quickly browsed through the stuff at http://x2go.obviously-nice.de/deb - but I couldn't find what I am looking for. Thanks in advance, Jörg
