Pre configuration
by Dick Kniep 22 Jun '10

22 Jun '10

Hi List, Some more questions about how certain things work in x2go. We want to pre-configure the x2go client in such a way that during installation it tries to make a connection to the user directory to share that directory automagically. Furthermore, clientside printing should be turned on automatically. How can we make that happen? Cheers, D. Kniep

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.

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?

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 !

Extra functions requested in x2go
by Dick Kniep 19 Jun '10

19 Jun '10

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. (See www.lindix.nl, text is Dutch) Currently we use GoGlobal but we want to switch to x2go. However, there is a missing piece. In GoGlobal it is possible to start an application on the client by the use of the extension of the file. So I can write an Excel sheet in my application and subsequently start the file, the result is that a local session opens on the client with the Excel sheet. I realize that there are security issues here, but for our application this would be a real bonus. Is there any chance this could be implemented? If the number of hours involved is reasonable, we even would pay for that. Cheers, D.Kniep

CLI / plugin
by Jörg Sawatzki 12 Jun '10

12 Jun '10

Hey folks, first of all I'd like to thank you for your excellent work! I just gave x2go a try on my virtual server running ubuntu hardy and I am quite impressed how easy it was to set it up and how fast it works. One short thing concerning the new plugin (which is not yet released, I know): I am on ubuntu lucid here (amd64) and firefox 3.6.3 - browsing to http://plugin.x2go.org and installing the plugin works perfectly. But: After installation, browsing to plugin.x2go.org makes firefox crash with the following command line output: firefox-bin: ../../src/xcb_io.c:249: process_responses: Assertion `(((long) (dpy->last_request_read) - (long) (dpy->request)) <= 0)' failed. Just as a hint - but probably you already know this issue... Anyway, now my actual question: I am developing a portable learning and working environment for the state of Lower Saxony targeted to schools (http://www.n-stick.de) Basically users put it on their USB stick to manage their portable programs and get updates using an apt-get like repository providing software and learning materials. If they e.g. install openoffice through the package manager, they can double click an *.odt file in the builtin file manager and it is opened with their openoffice. You probably already guess what I am thinking about: It would be cool if they had an option to say "Edit online" - in the case they don't have the appropriate application on their stick. Our portable desktop would then start x2goclient and popup an openoffice window on the remote x2goserver configured in the user's settings. I had a look at x2goclient-cli which could easily be executed by our python app. A few questions: - most of the users are using Windows - is or will the CLI be available for windows as well? - is there a way to tell the CLI that it should let the local window manager render the windows? If I use it with --command xterm for example, a 800x600 virtual desktop pops up and contains an xterm window. I have seen the x2goclient-gtk/qt can do that, but I am not sure how to do it with the CLI. - if the user clicks a file on his USB drive the terminal server will need access to it - is it possible to get that working with the CLI? Thanks once again and have fun at LinuxTag :o) Jörg

How X2Go works
by John A. Sullivan III 11 Jun '10

11 Jun '10

Since we are not developers, we struggled to gain an understanding of just how X2Go works under the covers - what is it doing from a system administrators perspective when a client connects, suspends, or terminates. Thus, I've attached my notes on what I have found. I have no idea if they are helpful or even accurate but here they are for what they are worth. Any corrections are most appreciated. Thanks - John

Local share rights

Hello, all. We're getting some complaints from Windows users who are using the X2Go client local share facility. When they view the local file system from their X2Go desktop, they frequently see highly restrictive permissions - frequently 000. Has anyone else noticed this problem? I'm a Windows ignoramus. Is there a way to change the local file system so it saves files with more X2Go friendly permissions? Thanks - John

Ubuntu 10.04
by cougarmaster 08 Jun '10

08 Jun '10

Hi all, I have just installed Ubuntu 10.04 for a client on a XEN server and the login and using of the gnome desktop was really great! It was very fast login and using the programs was quick and no long waits. The login took about 6 sec from an internet connection. Though video playback is terrible still :) but the sound was smooth mostly having a few stops here and there otherwise its really good. Printing was great but had to stick to pdf printing which the client could live with pressing a few more buttons. The other great thing was that if the connection was cut off for whatever reason it now can connect back to that session, before it was like a roll of the dice. Also another great factor was using 10.04 is login and log out are really fast. The modem setting is a great saver for bad wifi connections. Anyway my main question would be will video playback be looked into? Since with ubuntu 10.04 out and most of the things I have tried seems to have enhanced the speed of ssh and stability. Though most people don't need it now it is a great feature to have since video calls are getting popular it would really enhance x2go usage further.

Seemless sessions using GDM?
by Jo-Erlend Schinstad 07 Jun '10

07 Jun '10

Hello everyone. On my home desktop, I use Ubuntu 10.04. I use it for personal stuff and I use it for business, but then using an x2go terminal server. And I'm very satisfied with that solution. However, yesterday, I tried something new, and the result was 99% awesome. What I did, was to add a new session type to GDM, which I called x2go. This session simply runs x2goclient --geometry=fullscreen --session=x2go and some other parameters. The x2go session uses a spesific user and key, so it wouldn't be a good solution in all cases, but since I'm the only user of this particular pc, it's not a problem for me. Having setup the client to use a key for login, this means that when I login as my x2go user in GDM, the only thing I see, is the x2go session. This is really very nice, but when I log out from the x2go session, I end up with the x2go window. It would be very nice if I could find a way to exit the application when I log out from the x2go session. Is this possible today, or must it be coded? Thanks, Jo-Erlend Schinstad

Re: [X2go-dev] X2go-dev Digest, Vol 18, Issue 7
by brian mullan 07 Jun '10

I've tried most of the remote desktop solutions out there. NoMachine's NX, NX/FreeNX, Citrix ICA, etc. They *all* suffer from less than perfect video over the net. Its a combination of bandwidth and cpu horsepower either of which can induce delay/jitter. Audio won't be as noticable as video because if you miss some bits of audio your ears/mind usually still can understand but miss some bits of video and its always noticable. There are quite a few solutions that are starting to appear though that will help. Red Hat has released to opensource the SPICE<http://www.h-online.com/open/news/item/Red-Hat-open-sources-Qumranet-SPICE-…>software they got from QumranNet two years ago. There is also work being done with Neatx although its got key features that don't work yet (audio/printing for a couple). and there are a variety of other solutions starting to hit the market. Then there is the movement to HTML 5 with embedded video support which is going to change a lot of things for the better. If the video you need to view is web based then don't have the user launch a browser on the remote desktop machine but launch it locally.

x2gothinclient: pre-select session?
by Philipp Huebner 04 Jun '10

04 Jun '10

Hi, today I successfully replaced LTSP by X2Go on a Debian Edu Terminalserver. On the server I just installed x2goserver-one. In the Thin-Client chroot I modified /etc/init.d/ramdrive to create a sessions file that offers a session for the Terminalserver. It works like a charm: the user clicks on the card, enters his username and password, and there he goes :) Now, to top it all off, it would be great if I could get x2goclient to pre-select that session. In my setup there is only one Terminalserver, and that way the click on the card would be saved. Currently, I have the following in /opt/x2gothinclient/etc/default/x2goclient: x2goclient --external-login=/ramdrive/logins --no-menu --maximize --link=lan --kbd-layout=de --kbd-type=pc105/de --set-kbd=1 --geometry=fullscreen --add-to-known-hosts --read-exports-from=/ramdrive/export If I just add --session-id=20100603181957574 to that list, x2goclient won't start. that argument alone doesn't work either. So my question is: if possible, how can I pre-select a specific session for the x2gothinclient? Regards, -- .''`.

Serious Issue - x2goagent runaway CPU
by John A. Sullivan III 04 Jun '10

04 Jun '10

Hello, all. We are seeing this with enough regularity that it is alarming. Our first client uses Konqueror heavily in their work process. They usually open files from it rather than from within the applications, they email directly from it, etc. The environment is Lenny + Backports with a few updates from Squeeze. We are using KDE 3.5. X2Go is 3.0.1-4 on the client (all windows stations) and 3.0.1-5 for server. We have not been able to track down the trigger but the user's Konqueror will freeze partly painted. x2goagent consumes all the CPU and Konqueror's memory usage grows to frightening amounts (e.g., 18GB). How can we track down and kill this serious bug? Thanks - John

Compensating for heavy packet loss environments
by John A. Sullivan III 03 Jun '10

03 Jun '10

We have some clients who are experiencing heavy packet loss on their Internet connection. As a result, their X2Go sessions regularly hang and then take forever to time-out. Their other Internet traffic is much more resilient. This sounds like an SSH problem which does have a problem with lossy environments. We've started testing with changing the sshd_config to have: ClientAliveCountMax 12 ClientAliveInterval 5 Any other suggestions or experiences in using X2Go in high packet loss environments? Thanks - John

Fwd: x2go with ldap, but no login

-------- Original Message -------- Subject: x2go with ldap, but no login Date: Tue, 1 Jun 2010 06:37:46 +0200 From: lug limbe <lug.limbe(a)gmail.com> To: kamerun(a)immerda.ch, "lug.limbe" <lug.limbe(a)gmail.com> hello, first a question: i will come in europe in july august, september, last year i participate to a x2go meeting in germany, it was very nice and helpfull for me. if it exist something similar (workshop, seminar, ...) please tell me, i woud like to participate. as we quasi promise, we install x2go with ldap. we install x2go with x2go-home on ubuntu and x2go-one with debian without ldap without problems. we want to have 2 x2goserver with load balance, it would be very nice, because if a server is not working, we can still work with the other server, if both are working, with load balance it should help for better performance. so we tryto install x2go with ldap. it has taken more than 2 days: we have a 128 kbs connection, but the worse ist the current, which stop every 20-30 minutes when the rain is heavyl falling down (we are in the raining season. it seems to work fine, but when i want to start a client (PXE) i come until the login, but it appears only the icon to shutdown and nothing else. as you can see in syslog and better understand as i, slapd is working, every 5 seconds happens something it seems to close the connection */ /* /*May 31 22:52:21

update on the status of the new release
by Heinz-M. Graesing 31 May '10

31 May '10

Hello x2go user, we've finally found the bug preventing the release of the new version. Now there will be some changes to the feature list of the upcomming release: To keep it realistic there will be no audio support for the desktop/session sharing feature (for now). It won't be possible to modify a shared session which is not yours (due to security reasons). There where also some requests regarding the needed KDE4 bindings. As KDE has changed a lot, we are discussing to build those as a "plasmoid". We'll make the new release accessible for testing purpuse soon - but the plasmoid will take us some time. best regards, Heinz

Windows X2Go printing
by John A. Sullivan III 29 May '10

29 May '10

Hello, all. We are trying to finish off the punch list for our first major X2Go deployment so I expect to be sending lots of smaller issues to the list. One not so small issue is a problem with using the X2Go client printing on Windows stations. The portability of this solution is magnificent but we are noticing that the windows client cannot directly print to the local printers. Whenever we send a print job from the X2Go server to the Windows X2Go client (3.0.1-4), the print dialog properly displays. However, no matter which local printer we choose, whichever application Windows has associated with PDF files opens instead and displays the PDF rather than printing it. Has anyone else seen this behavior? It is 100% reproducible for us. Why is this happening? Is there a workaround? We're about to dive into the code to see what we can find but really don't know what we are looking at or for so any guidance would be greatly appreciated - John

Public key authentication on Mac OS X
by Mihai Moldovan 28 May '10

28 May '10

Hi all, whilst using x2goclient on Mac OS X Snow Leopard, I came across a few problems. Initially, I thought I could just set up x2goclient to connect to my server which supports public key authentication. Actually, pubkey is my default authentication scheme when connecting to this very server and ssh always chooses it. Furthermore, the password for this very private key is saved in Mac OS X' keychain, providing a ssh-agent like (well, let's say identical) environment. First off, I guess you're only using the stock SSH client found on the machine yourself, so why don't you let it handle it the authentication and (optionally) query for a password, if this situation comes up? Secondly, if you dislike this, keychain integration is still very favorable on Mac OS X, as it saves the user the burden to provide a password for his private key. While this is not exactly very secure, it's very comfortable on the other hand. (Note: keychain can save the provided password and "enter" it automatically everytime the privkey is requested, but it's not necessary to do so. This said, users can of course choose whether the password is to be remembered or not.) I've seen that there is a way to select a private key for authentication in x2goclient. That's handy and I like it, really. As said before, ssh (and ssh-agent/keychain) could handle this as well, but it's nice to have such an option, i.e. when using a very specific key for this purpose only. Any disagreeing or agreeing thoughts on this? Best regards, Mihai

Opening a session to user with encrypted home directory
by Milan Knížek 28 May '10

28 May '10

Hello, there appears to be a problem with connecting to x2goserver-home (Ubuntu 9.10), when the user has encrypted home directory (using ecryptfs). The cause seems to be that some files need to be open in the home directory before the ecryptfs is mounted. Trying to connect again usually works. Also, the unsuccessful first session remains hanging as "running" in the server's database. I checked that after the first unsuccessful trial, the ecryptfs home directory was not mounted. Could it be caused by not enough time for ecryptfs mounting scripts to mount home directory before x2go wants to write to it?

It would be nice to have Mac OS too, but it's not very important to me. But you're saying PulseAudio would work nicely in Windows as well, so you can use two-way audio for VoIP, etc? > The configuration can be delivered via the webserver (as an *.x2go file) > and every feature of x2go is supported (bidirectional audio, sshfs, > x2goprint,...).

Re: [X2go-dev] X2go-dev Digest, Vol 17, Issue 14
by brian mullan 24 May '10

Loadbalancer's don't necessarily have to have anything to do with x2go or NX for that matter although they can implement their own technique. There are several good articles out there on the topic including this one<http://1wt.eu/articles/2006_lb/> . Here is one implementation <http://haproxy.1wt.eu/> you could also use. And here is a HowToForge article on setting up an Apache Web Server load balancer<http://www.howtoforge.com/high_availability_loadbalanced_apache_cluster> If you use some of the "cloud" services setting up a load balancer is often very simple. On the Amazon Web Services (AWS) Cloud (ec2) you just start your "instance" that is the application(s) you want to use and more or less a single click/command adds your new server to an EC2 loadbalance<http://aws.amazon.com/elasticloadbalancing/>r that you then can specify criteria for. AWS has made it ridiculously simple. Matter of fact, AWS EC2 just implemented a new "service" which can track which instance (re virtual machine) a session belonged to and IF the session terminates abnormally, you can restart it and between the Load Balancer and AWS EC2 it will reattach it to the original instance/machine. Read about it hear on How to setup a Load Balancer with Sticky Sessions<http://www.shlomoswidler.com/2010/04/elastic-load-balancing-with-sticky-ses…>. Jeff Barr is the author and works for AWS.

Does X2GO have support for scanning using a client-side scanner?
by Jo-Erlend Schinstad 23 May '10

23 May '10

One thing I've been longing for, is the possibility of scanning on the remote server using a scanner connected to the client. I noticed that 2X now supports this. Is it possible using x2go, or will it be possible in the future? Do you only implement stuff that can be done on all platforms, or will you make it possible using ubuntu clients even if it's not easily done for windows clients? Thanks. Jo-Erlend Schinstad

Windows client crash ASSERT failure
by John A. Sullivan III 22 May '10

22 May '10

Hello, all. We installed the Trolltech Qt SDK for Windows and downloaded the x2goclient-3.0.1-4 tarball from x2go.obviously-nice.de/deb Before attempting any changes, we simply built and ran the project. It crashed with: ASSERT failure in QWidget: "Widgets must be created in the GUI thread.", file kernel/qwidget.cpp,line 1133 Invalid parameter passed to C runtime function We tracked this down to initStatusDlg(). In line 7559, it calls slotShowAdvancedStat(). On line 3966, it calls st.sync(). When it calls QWinSettingsPrivate::sync() RegFlushKey(writeHandle()), it blows up. What have we done wrong? Thanks - John

Hello I'm trying to make binary packages for Fedora but I am little bit confused. I wonder if any "howto build it from scratch" exists? Can you give me some URL? Thanks Pavel

Which Windows build environment
by John A. Sullivan III 19 May '10

19 May '10

Hello, all. I'm getting ready to build a Windows X2Go development environment to do some troubleshooting on some issues we have. What is the Windows build environment currently used by the development team. I'm in the process of installing eclipse but I know the CVS includes the KDevelop project file. I suppose it would be best if I used what the developers use. Thanks - John

Windows fullscreen and clipboard parameters not passed
by John A. Sullivan III 19 May '10

19 May '10

Hello, all. I'm working on the problem where Windows clients do not honor the full screen setting nor pass clipboard information. I noticed in the thread which starts the Windows Xming server, void ONMainWindow::startXOrg (), that the Xming parameters appear to be hard set: args<<dispString<<"-multiwindow"<<"-notrayicon"<< "-logfile"<<xorgLogFile; xorg=new QProcess ( 0 ); xorg-> setWorkingDirectory ( appDir+"\\xming" ); xorg->setEnvironment ( env ); xorg->start ( appDir+"\\xming\\Xming.exe",args ); Before try to generate a patch to add -clipboard as a fixed setting and read the screen parameters from the settings file, I thought I should as, why do we not pass -clipboard and why do we not read the screen settings already? I certainly wouldn't want to waste any time if we already know -clipboard and either -rootless or -fullscreen are really bad ideas. If there are not reasons why this is not done, I can try to work on a patch tomorrow. I'm very unfamiliar with Qt on Windows (and am barely functional running it in KDevelop in Linux!). How does one normally build in Windows? Thanks - John

Password handling and CAPS lock issues
by John A. Sullivan III 18 May '10

18 May '10

Hello, all. We have a problem with CAPS lock getting out of sync between the physical and virtual desktops. I assume this is the downside of the very powerful feature of being able to change physical computers connected to the same virtual session. However, it is more than annoying. Because X2Go attempts so many logins at once (separate SSH sessions for video, print, sound, file sharing), a wrong login quickly exhausts grace logins and can even trip our OSSEC active response as a perceived brute force intrusion attempt and lock out all computers from the same site. Perhaps password handling could be improved in two ways in X2Go. If the first password attempt fails, the user should be alerted and continued login attempts for other ssh sessions should cease. Secondly, the first failed attempt could be retried in reverse case. If it succeeds, a message should be displayed to the user. The problem could be either that their physical CAPS lock is on (in which case we do nothing but warn) or that the CAPS lock is out of sync, in which case we can offer to toggle the CAPS lock state on the virtual desktop. Is this possible? Is it reasonable? Thanks - John
