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

Re: [X2go-user] X2go-user Digest, Vol 9, Issue 6

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. In > all networks I administrate there is one desktop workstation that runs > x2goserver. I use GNOME or LXDE to access the network components from > this X2go server. 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

Hi, I am a Fedora user and would like to see if I can get x2go to work on Fedora. The instructions on the web site refers to Debian packages. I wonder are there documents describing how to build and install from source? Thanks -- Andy Tai, atai(a)atai.org, Skype: licheng.tai Year 2011 民國100年自動的精神力是信仰與覺悟自動的行為力是勞動與技能
