To pertain the former 3.4.0.x versions on packages.x2go.org (main) and on Launchpad (ppa:x2go/stable) I have moved packages appropriately. The 3.5.x versions of NX libs + proxy + x2goagent (later today or tomorrow, at the latest on Saturday) will be in the nightly builds only for quite a while, only.

Problems with ssh keys and intermediate ssh hop
by Karsten Heymann 28 Jun '11

28 Jun '11

Hi (especially Mike :) ), we're currently evaluating x2go on debian squeeze (server) / ubuntu natty (client). Basic functionality works, but some of our users will need access via an intermediate ssh hop. Now if the x2go clients (I tested x2goclient and pyhoca-gui) would honour ~/.ssh/config, I could simply roll out a ProxyCommand line, but so I have to resolve to setting up the relevant tunnels manually. pyhoca claims to have some support for intermediate hops, but I was not able to use it in any understandable way. What's the recommended way to achieve this feature? Also, pyhoca-gui was not able to accept my rsa private key and claims it's a invalid dsa key (which is correct but not helpful ;) ). If any of this is wrongly adressed here, please point me to the correct place.

Mac client printing
by John A. Sullivan III 27 Jun '11

27 Jun '11

Hello, all. We suddenly have a number of Mac client users. We do understand that sound will not work because there is no pulseaudio for Mac. However, printing is not working either. We have gotten it to work in the past by enabling remote access (sshd in effect). However, we have done that on the last three Mac clients and it has not worked. We have gotten error messages that sshd is not running and yet we have started the service. As most of us here are Mac ignoramuses, any idea why this is not working and how we fix it? Thanks - John

Installed x2goclient on Fedora 15
by Daniel Lindgren 18 Jun '11

18 Jun '11

Hello. I wanted to try Gnome3 with Gnome Shell and couldn't make it work on Debian, so I installed Fedora 15. AFAIK there are no x2go client packages for Fedora, but there are packages for Mandriva. Getting them to install on Fedora wasn't that difficult, I've documented it here: http://wiki.x2go.org/installing_x2goclient_fedora Please note that there is no support - from me or anyone else - on this. That said, it worked pretty much out of the box. Cheers, Daniel

Dear X2go-users/-devs/-other-wise-interested, we have slightly changed use cases and purposes of the X2go mailing lists: http://wiki.x2go.org/community The x2go-announcement list is now fully dedicated to human-readable X2go announcements (like this one). Note that we have disabled digests for this list. You can expect it to be of very low traffice from now on. The Git tags that have been posted to the x2go-announcement list recently have now been moved to a different read-only list: x2go-tags(a)lists.berlios.de, people on x2go-announcement who were interested in this automatic postings from X2go Git should subscribe to x2go-tags now. Please see the wiki page given above for details.

Ubuntu Natty X2go client
by Neil Hunt 08 Jun '11

08 Jun '11

All, I know Mike got X2go server running on Ubuntu 11.04 Natty. I haven't been able to do that yet but that's not my particular concern at the moment. I was wondering if anybody has used X2go client (either standard GTK client or Py Hoca) on an Ubuntu Natty desktop machine. I am trying to use Py Hoca client right now on my Natty computer, but when I launch PyHoca I get: administrator@ubuntu-kiosk-7:~$ pyhoca-gui pyhoca-gui[5662] (PyHoca-GUI) WARN: the current release of PyHoca-GUI does not support client configuration The logo pops up in the middle of the screen, but then nothing shows up anywhere. I see the process running, but I can't find any icon indicating it's running. Has anyone tried this successfully? Thanks, Neil

Installation on multiple nodes
by Florent Lévigne 07 Jun '11

07 Jun '11

Hi, I tried the installation of x2go on Debian Squeeze, with the repository. With one serveur, it works, but I would install it on multiple servers. The documentation explained how to do it, using LDAP (but it was not up to date, packages like x2goldaptools does not exist anymore), the page of the wiki about it is now removed. I found nothing explaining how install the current version of x2go on multiples nodes. Thank for any help. -- Florent Lévigne - flevigne(a)dotriver.eu - www.dotriver.eu

Re: [X2go-user] Ist X2Go eine ernsthafte L?sung oder Bananensoftware? (Tim-Ole Alexander Golz)
by nigra truo 03 Jun '11

03 Jun '11

Hi What I can contribute is that I have been using X2go for more than 6 months now and very successfully. I run the server on Debian Squeeze (and Lenny before) and connect to it from Windows 7 and Ubuntu 10.04 and Debian Squeeze (Laptops). So far I have had some issues, but it is very stable. So stable in fact that I am often working remotely on my server at home (connect over the internet via SSH). Resuming works almost always and I have to say, I am surprised how well it works. I would like to extend my congratulations and thanks for this nice piece of software to you developers! I have used Nxserver and NXfree (or freenx, I always confuse them) and that used to work much worse, with suspending and resuming spotty at best. (I have to admit that this does not comment the commercial version of NXserver, which must be much better I am sure) It is unfortunate that you have having so much trouble getting it to work, I can relate to this, as your question indicates, like "is this working ANYWHERE?" and yes it does, very well. So I am sure there must be some way that you can get it to work. But when it comes to open source, yes, the documentation can be lacking and sometimes it takes a long time and strains the patience. What I can say is that it is worth the work, since the software works very nice and I am glad that finally I can use my server at home as the unlimited (no more 2 or 3 user limit) terminal server that I have always wanted. Even audio forwarding works (on Windows, so I can hear the pulseaudio on my server session, EVEN THOUGH I have Jackd audio deamon running on it. How this can work is beyond me, a positive surprise to be sure. And filesharing works also. I also understand and write German, but I understand that this mailing list should be kept in English, so I hope you can understand me. I know that my configuration is kinda simplified, as I am not using LDAP or any kind of complex user authentication mechanism. It might be easier to get it working simple, before trying to tacke these. The repository that I am using currently are these, just in case this helps: deb http://x2go.obviously-nice.de/deb/ lenny main (I actually went to my open terminal session window and copy pasted it (even this works)) As you see, I am still using the lenny repository (in case there is a newer one) and use the server and here are the packages that I have currently installed: pinentry-x2go install pinentry-x2go-gtk install x2goagent install x2gocdmanager install x2goclient install x2goclient-cli install x2goclient-gtk install x2gokdebindings install x2goserver install x2goserver-home install x2goserver-one install x2gospyglass install x2gousbmount install Just in case this helps... as you can see I am using the x2goserver-home or one version which is simplified without all the bells of whistles of authentication, if I understand it correctly. I remember one issue that I had was about Xming not running in Windows (which is the component that acts as Xserver). In my case it was not started automatically. Another thing is my /etc/sudoers config ### X2GO section %x2gousers ALL=(ALL) NOPASSWD: /usr/bin/x2gopgwrapper #### X2GOPRINT section x2goprint ALL=(ALL) NOPASSWD: /usr/bin/x2goprint And I remember having an issue with that. These settings might be too insecure for your taste, but it is easiest to first open things up and circle the problem wide, to see where it is located at. Hope this helps.. Markus

Performance issues using RDP
by John A. Sullivan III 28 May '11

28 May '11

Hello, all. We were very eager to experiment with TSPlus (http://www.tsplus.net) as an alternative to Microsoft RDS. We have been assuming all along that performance of any RDP solution is better in a low bandwidth WAN environment if we put X2Go in the middle of it and run rdesktop from the X2Go Server to a local Windows server. Our results were very disappointing with both TSPlus and RDS and with both rdesktop and xfreerdp. Has anyone else experienced the same poor performance or, more importantly, has anyone worked around it? We noticed that screens seemed to be painting line by line - not sure if if it is the entire screen or just the active window. It also made mouse movements very erratic in TSPlus + rdesktop. TSPlus + xfreerdp seems better. To demonstrate this, I opened notepad in a large window in a full screen session, typed an entire line, copied it to the clipboard and then held down <CTL>V to paste it. The first few lines flew but then it became very slow and we could see the flicker of each line painting. I also opened Internet Explorer and went to www.spiritualoutreach.org - a very poorly designed site I put up years ago with long pages and far too large graphics. I sat and watched the screen paint a band at a time. I opened one of the large template documents and vertical scrolling was nearly impossible. I'll paste in some of our internal notes below. Thanks - John BEGIN NOTES Good afternoon, Phil. I've dropped an unexpected several hours into this this morning with some good, some bad news, and some inconclusive news. There is an alternative to rdesktop named freerdp which aims to implement the newer protocols as rdesktop is barely being developed. Last I used it, it was very lacking but I installed the current Squeeze version on my netbook and connected to windesk01 across the VPN (xfreerdp -d mydomain -u myid -a 32 -x lan -f --plugin cliprdr tsplusserver ). The results were stunning. Performance was quite usable directly through the VPN, i.e, not using X2Go as an intermediary. The silly test I was using to see the line by line painting (opening a large notepad, typing a full line, copying it to the clipboard, and then holding down <CTL>V to continually paste it) worked quite well. I did the same thing to RDSServer where I had some large architectural drawing stashed and they scrolled largely seamlessly. I then returned to my VD, installed freerdp-x11, and tried the same. The results were most disappointing - the same problems of slow, line by line painting. I also noticed that the full screen toggle (<ALT><CTL><ENTER>) mangled whereas directly on the VPN, it did not. I wonder of there is some sort of conflict between the way NX and RDP paint the screen? I then tried the same thing using simply rdesktop. The performance over the VPN was better than I remembered. I also contrasted RDSServer and tsplusserver. I'm not sure but it is possible that TSPlus is actually getting heat for something they are doing well. The line by line screen painting in my notepad test was much more noticeable in TSPlus but the overall performance was about the same. I wonder if TSPlus is painting the screen faster and so we see the repaints whereas RDS is hiding them by not updating the screen as quickly. I don't know - just a thought. I'm continuing to play around with this quite a bit. In fact the above paragraph was typed from a direct full screen Windows desktop via X2Go. This paragraph is being typed across the VPN directly on tsplusserver using xfreerdp. The keyboard response seems about the same. For kicks, I opened KWrite on my Trinity desktop and tried the same pasting test to see if the screen painting was line by line. It was not; it flew. So it is something in the interaction between RDP and NX. To create the X2Go direct Windows session, create new sessions (one for tsplusserver and the other for RDSServer). The type should be Custom Desktop (NOT single application) with the command line as described above). Remember to set the compression type to 16m-png-jpeg and the display DPI. I'll be very curious to see what you see. END NOTES

Stefan, I tried long and hard to get the xorg.conf file to work with my monitors to no avail. Debian simply did not have the intelligence to detect various monitor configurations and I finally had to unfortunately give up. Probably not the answer you want, however I can say that we went a different route and it's worked just fine: we decided to create a custom Ubuntu Live CD image and boot to that via PXE. Ubuntu picks up virtually any monitor settings and audio works great as well over PXE. I created a custom kiosk mode so a user boots up right to a full-screen x2go client, just as the x2go-thinclient package did. The two links I used were https://help.ubuntu.com/community/LiveCDCustomization and for setting up the kiosk mode, I used this description (made for NX, but just replace the NX settings with the x2go_gtk client and all worked fine). http://blog.nistu.de/A_kiosk_setup_with_nxclient.html Let me know if you have any questions.

Re: [X2go-user] x2go thinclient - custom xorg.conf
by Stefan 24 May '11

Hi Neil, thanks for answering. This is indeed a option. Since I got very good experiences with the live-helper tools from debian (http://live.debian.net/) this would be a possibility to create the live-cd-image even easier and more reproducable. Bevor I've seen the x2gothinclient-environment I was already thinking to make a pxe-bootable live-image with x2go-fullscreen-client this way. It's also available for ubuntu - but I've never tried. It shouldn't be more difficult than with pure debian (http://packages.ubuntu.com/de/hardy/live-helper) But if possible I would prefer a generic debian solution. So far I see x possibilities 1. hacking the x2gothinclientd script 2. building live-cd image (ubuntu) 3. setting up a special thinclient changeroot for each client which needs special configuration (with hard-links for all unchanged files) and booting with mac-specific pxe Since I've got already the custom xorg.conf for the clients which behave not like they should, I'll start with 1. For second way it would be great to use the live-helper script and to publish all configuration in the wiki. I'll do, if I find the time. The first way quick and dirty without changing the x2gothinclientd: I created a script /etc/init.d/x2go_xorg_custom ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #!/bin/bash # Workaround for custom xorg.conf # tests if custom xorg.conf for mac-address exists. # if yes copy to /ramdrive/tmp # if no the default xorg.conf.default kopiert # ein symbolixher Link /etc/X11/xorg.conf verweist auf diese Datei # make shure having always the same output of ifconfig: export LANG=C # getting Mac-Address for the eth0 -> has to be adjusted if the interface # isn't always eth0 xorg_file="xorg.conf.$(/sbin/ifconfig eth0|grep HWaddr | awk '{print $5}')" # tests if a custom xorg.conf.MACADRESS exists if test -e /etc/X11/$xorg_file; then echo $xorg_file; else xorg_file="xorg.conf.default" # echo $xorg_file fi # copiing the specific xorg.conf to ramdrive cp /etc/X11/$xorg_file /ramdrive/tmp/xorg.conf exit 0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ in the changeroot I made a link from the xorg.conf to the new one and add a starting-script before the x2gothinclientd chroot /opt/x2gothinclient ln -s /ramdrive/tmp/xorg.conf /etc/X11/xorg.conf ln -s /etc/init.d/x2go_custom_xorg /etc/rc2.d/S19x2go_custom_xorg Thanks a lot.

x2go thinclient - custom xorg.conf
by Stefan 23 May '11

23 May '11

Hi all, I installed recently x2go-one and the thinclient-netboot-environment. So far all works fine. (Sound and printing not yet tested). At the same network we have also a ltsp installation but I think to replace ist step by step with x2go mainly because of spee issues. One of the main questions I have ist if it's possible to offer custom xorg.conf to the clients which boot via pxe. Some of our monitors are not correctly recognized by the x-server an need a special xorg.conf. In the ltsp changeroot there is the possibility to offer something like xorg.conf.00:00:00:00:00 with mac-address as a suffix. Is there any similar possibility on the x2go thinclient system? If not yet: It should be possible to make some adjustments in the startscript. I would try to make a hack in the /usr/sbin/x2gothinclientd to ask for mac-address to choose a custom Xorg.conf. But maybe there is already a solution? I think it would make sense to change the x2gothinclientd script in this way. Best regards Stefan

X2go stable ppa on Ubuntu Launchpad
by Mike Gabriel 18 May '11

18 May '11

Hi List, A couple of hours ago we have set up a stable ppa for X2go on Ubuntu Launchpad. From our nightly-builds we will pick packages that appear rather stable/successfull/blessed and copy them to the following ppa at Launchpad: ppa:x2go/stable @Ubuntu users: please use this ppa for setting up your systems. Further info can be obtained from the X2go wiki. http://wiki.x2go.org/adding_the_x2go_repository_ubuntu People still using the nightly-builds from ppa:x2go/ppa are on their own from now on... Those packages might be broken from time to time. Please change over to ppa:x2go/stable.

Ist X2Go eine ernsthafte Lösung oder Bananensoftware?
by Tim-Ole Alexander Golz 16 May '11

16 May '11

Hallo, Liste, entschuldigt die etwas provokante Frage, aber wir müssen mal ernsthaft fragen, ob es da draussen jemanden gibt, der X2go einigermassen brauchbar installiert und eingerichtet bekommen hat - sonst brechen wir an dieser Stelle (nach drei Tagen Ausprobieren) lieber ab und suchen nach einer anderen Lösung. Es ist eine schwierige Gratwanderung, OpenSource-Projekte konstruktiv zu kritisieren: ich weiss die aufopferungsvollen Bemühungen der vielen Entwickler durchaus zu schätzen, und eine Spende oder die Entrichtung sonstiger finanzieller Unterstützung ist für uns selbstverständlich. Und sicher dankt kaum jemand den Entwicklern die Arbeit. Auf der anderen Seite: Eine Software, bei der *dermassen* viel *nicht* funktioniert, ist uns selten untergekommen - und das erstaunt mich vor allem deswegen, weil X2Go in letzter Zeit eine sehr positive Presse erfahren hat. Wir suchen nach einer Alternative zu FreeNX und haben zu Testzwecken einen Debian Squeeze installiert; dann haben wir es mit Leny versucht, schliesslich mit Ubuntu 11.04 - es funktioniert (fast) NICHTS ... Keine der Anleitungen, die man bei X2go zu Debian und Ubuntu findet, ist stimmig, aber so etwas kennen wir ja aus der OpenSource-Welt (und auch aus der Microsoftwelt, übrigens!!): entweder stimmt der Keyserver nicht (was ja noch vernachlässigbar ist), oder der empfohlene x2goserver-home ist nirgends in den Repositories vorhanden; oder man nimmt die Squeeze-Repositories und hat dann kein Script x2gocreatebase.sh, oder es gibt ansonsten jeder Menge Unstimmigkeiten und Fehlermeldungen. Nun ja, wir beissen uns irgendwie durch, und schliesslich haben wir einen X2goserver installiert, per PHPLdapAdmin User angelegt, der Gruppe x2gousers hinzugefügt, /home-Verzeichnisse angelegt und uns testweise per ssh auf dem X2goserver eingeloggt - die LDAP-Anbindung fukntioniert also, und ein Starten des X2goservers führt auch zu keinen Fehlermeldungen. Es gelang uns bisher aber weder mit Mac (10.5.6 auf Intel), Windows (XP) noch Ubuntu 11.04, eine Verbindung zustande zu bringen. - unter dem Mac kommt es trotz vorhandener X11-Application zu einer Fehlermeldung, dass kein X11 vorhanden wäre, und dann zu einem Timeout im Vwerbindungfenster. Das Mac-Log sagt dabei: macbook DirectoryService[11]: Failed Authentication return is being delayed due to over five - unter XP erscheint die ssh-Key-Abfrage und wird bestätigt, es erscheint für den Bruchteil einer Sekunde ein Fenster (der KDE-Desktop?), dann bricht die Verbindung ab mit dem Windows-Fenster "Befehl konnte nicht ausgeführt werden: startkde" Im Client erscheint: NXPROXY - Version 3.0.0 Copyright (C) 2001, 2007 NoMachine.

Als wir C:\Dokumente und Einstellungen ... \.x2go gelöscht hatten, konnten wir wenigstens ein schwarzes KDE-Fenster sehen - aber es bliebt schwarz, nichts verwertbares ist damit anzufangen :-( - und unter Ubuntu 11.04 führt weder die Installation und der Aufruf von /usr/bin/x2goclient noch von /usr/bin/x2goclient-gtk (mit vorweg installiertem pinentry) zu irgend etwas - die Anwendung startet schlicht nicht, das Aufrufen per /usr/bin/x2goclient oder /usr/bin/x2goclient-gtk führt zu: root@ubuntu11:/# /usr/bin/x2goclient_gtk ** GLib-GIO:ERROR:/build/buildd/glib2.0-2.28.6/./gio/gdbusconnection.c:2279:initable_init: assertion failed: (connection->initialization_error == NULL) Abgebrochen beziehungsweise root@ubuntu11:/# /usr/bin/x2goclient /usr/bin/x2goclient: error while loading shared libraries: libQtNetwork.so.4: cannot open shared object file: No such file or directory Huffda ... jetzt sind diverse Arbeitstunden vergangen, und es ist nicht irgendwo ein Lichtlein zu sehen - wenn wenigstens irgend einer der Clients funktionieren würde ... wir testen jetzt nur nochmal Ubuntu 10.10. Deswegen die wirklich ernst gemeinte Frage: gibt es irgendwo X2go im Produzktioveinsatz? Mit einer Infrastruktur aus Feld-, Wald- und Wiesen-Debian, Ubuntu, Windows XP? Wobei wir eine der Hauptkriterien - die Verbindungsmöglichkeit von IGEL-Clients aus - noch gar nicht getestet haben, ich kann mir im Moment nicht vorstellen, dass der Netboot funktioniert, wenn schon keiner der Clients brauchbar ist. Im Gegenzug helfen wir gerne aus mit Dokus schreiben, Webspace zur Verfügung stellen, Spenden zahlen - aber es sollte doch irgendwo eine halbewgs brauchbare Installationsmöglichkeit für X2go geben?! Im Moment kann sich das hier bei uns niemand vorstellen :-( Vielen Dank im Voraus für eventuelle Tips / Hilfe / Hinweise!! Tim-Ole Golz

Hi, Mike, thanx for your answer - and sorry, I actually forgot the reminder on the Mailman-website regarding the language ... by the way: a bit strange since X2go is as well a german-based project (as far as I can see) as the main part of information on the web is in german, too ... ;-) but there may not be enough interest for a standalone german-list. a brief conclusion (Mike, you got it fairly good!): - we are working on a (professional) project with server-based computing. The main interest is to supersede Microsofts RDP and Nomachines NX. - we tried X2Go with the Installation-documents from www.x2go.org on different virtual machines (Debian Lenny, Squeeze, Ubuntu) - the installation is more or less straightforward, but the documentation is unfortunately full of errors. But it *is* possible to get X2go to work on the serverside - and the LDAP-scripts are very good (so far as we can see)! - but none of the clients we tried worked :-( We tried those for MacOS on an 10.5.6-Intel-System, for Windows on a XP-System, and finally two clients for Ubuntu (x2goclient and x2goclient-gtk). It all results in more or less meaningful errormessages, crashes of the appliance and tine-outs on the client :-( We have *not* yet tested the Webclient and the Netboot-Environment. > Mike: I personally use X2go productively as a system administrator.

I install x2goserver from the new squeeze repos and > everything works out of the box (sqlite). As clients I use x2gocleint Sounds good! As we are documenting all the steps we execute in test-environments - do you have a (working! ;-)) step-by-step-documentation for, lets say, Squeeze? Oh, of course: I could send you our three documentations (Debian Squeeze / Debian Lenny / Ubuntu) where we have written down all the errors and broken links and strange behaviours we have experienced with x2go. > I also work for a company in the Netherlands that uses X2go for > full-featured SaaS.

On the other hand; there are damn few alternatives to X2go ... Not to forget: of course we can pay for regular X2go-Support and give the results and experiences back to the community. And we understand that X2go is a very ambitious project with little ressources ... greetings from the other side of the Eems! ;-) toag
