by Ricardo Díaz Martín 14 Nov '12

14 Nov '12

Hi, Is there somebody with x2go client working in MAC OS X Leopard or Snow Leopard? I have try in two different mac box and I always get the same message info "Can't connect to X-Server. Please check your settings". In settings looks like all ok (path to X11.app in mac osx is ok and verify it got right permissions). X-Server in both macs are installed and running. I have try to connect to nomachine linux server and X works fine. Some tips? Regards, Ricardo Díaz

sound on x2gothinclient
by Philipp Huebner 04 Jul '11

04 Jul '11

Hi, following the manual for Debian Lenny I have set up a x2gothinclient, but I can't get the sound to work. Any hints how to debug this problem? alsa recognizes the soundcard, it is supportet by the running linux kernel. Is it correct that there is not a single pulseaudio package installed inside the chroot? Regards, -- .''`.

Hello, is there a way to use x2goclient with ssh-agent(1)? i am using ssh-agent with my etoken to login via nxclient on some machines. is this possible with x2goclient? i've started x2goclient from the same shell where a ssh login to the remote server worked with agent auth. but x2goclient seems not to use the running ssh-agent. thanks for any help. heiko

x2go-home
by Alexander Crössmann 03 Mar '11

03 Mar '11

Hallo, ich bin ein absoluter Neuling hier und hab mir auf Ubuntu 9.10 x2go-home installiert. Leider kann ich mich über den client nicht einloggen. Die Fehlermeldung lautet "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server.". Ab und zu sehe ich noch das hier " NXPROXY - Version 3.4.0 Copyright (C) 2001, 2007 NoMachine. See http://www.nomachine.com/ for more information. Info: Proxy running in client mode with pid '25163'. Session: Starting session at 'Fri Aug 13 10:29:55 2010'. Info: Connecting to remote host 'localhost:30002'. Info: Connection to remote proxy 'localhost:30002' established. Error: The remote NX proxy closed the connection. Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Fri Aug 13 10:29:56 2010'. Session: Session terminated at 'Fri Aug 13 10:29:56 2010'. NXPROXY - Version 3.4.0 Copyright (C) 2001, 2007 NoMachine.

Anmeldename ist mein lokaler Name, der auch in der entsprechenden x2go Gruppe ist. ssh Port ist bei mir nicht 22, das habe ich aber entsprechend eingestellt. Kann mir jemand sagen woran das jetzt noch liegen könnte? Viele Grüße Alex

x2go security Issues
by Moritz Struebe 21 Feb '11

21 Feb '11

Hi, Morning, I am testing PyHoca. One of the problems a came around is, that the client checks whether I am in the x2go group - which I'm not. I also noticed that some other security-checks are done in the client. I believe this is dangerous, because administrators might think that these are real security checks, while they can easily be circumvented. I believe these check must be done server-side. That way they can also easily be adjusted by administrators. Besides that, one of our admins did quite a few security patches to avoid x2gowrapper having to run as root. At the moment this only works for Postgres. None the less I must say that I'm not happy running x2gowrapper, which is easy to exploit using SQL-Injections, as root. It should at least do a "sudo -u x2go" or similar. This user only needs access to the database. That way worst case the db is corrupted and not the whole system. Cheers Morty -- Dipl.-Ing.

X2Go Client Code Changes
by --[ UxBoD ]-- 18 Feb '11

18 Feb '11

Hello All, We are deep into the x2goclient code at the moment getting it to work better with vcxsrv and have a question around when the X server is started. It would appear that SSH, X and Pulse are all started, on Windows, when the application is initially launched. We can understand why SSH and Pulse are though unsure about X. Was there any technical reason why X could not be launched when a business card was selected and the login credentials entered ? Our thinking was that if it were launched then multiple sessions could be initiated each with there own display ID. We would very much welcome your thoughts on this matter before we spend to much time attempting to make the code changes. -- Thanks, Phil

Re: [X2go-dev] re Project Management
by Angela Fuß 10 Feb '11

Dear Heinz, Alex, Mike and Moritz, Dear List, the actual message I want to leave here is short - but I think I have to give some explanations first so that my message doesn`t irritate anyone here (probably a rather female way of saying something, we like to explain things lengthy ;-)). The professional background of writing this mail is, that mike and I are working together at a project in which we are setting up (educational) IT-Systems at schools in Kiel. We want to use X2Go for this project and thats why I started reading this list a couple of weeks ago; its also the reason why I am very interested in having X2Go work well. I have no technical IT-backgound, my contribution to and role in our project is to set up and implement a well-performing structure for all the communication that is needed (leading seminars, coaching, mediation, moderation of meetings etc.). The private background is that I am in relationship with mike - that was first, the working together started only a few months ago. One reason why I really enjoy working in an IT-context using Open Source Software is because I am deeply moved and inspired by the social, political and collaborative context in which every step of development is taking place. Thats my context in which I am reading this mailing-list. Now I have just read Mikes last mail and the only thing I want to contribute is: YOU GUYS MUST TALK! The guys I mean with that are Moritz, Alex, Heinz and Mike. As far as I can see the four of you are all giving your best to do a very good job - but you might generate heavy misunderstandings and lots of extra work if your communication at this point of the developing process is taking place "only" via mail and programming. There are very cheap telephone numbers which you can use for conference calls, I could give some of that numbers to Mike. I think it would not take much time to have a conversation on the phone, but it could take a lot of time if you dont talk alltogether about the next steps necessary to take. I am convinced that it would take a lot of stress out of the process, that it would move forward the whole project and that it would bring the freedom back into the space of the mailing list. And, very important: NOTHING IS WRONG - its all development ;-).
