I think all of the comments are good points regarding NoMachine's going closed source but I believe that precedence is that if you have historically provided the code under GPL you have already given those that use that software the perpetual right to continue using... just don't expect the originator (re NoMachine in this case) to fix bugs, improve on it etc. NoMachine also has their own issues to deal with as some of their software I have got to assume was implemented using GPL'd code or snippets thereof so they would have had to rewrite their own using someone with no knowledge of or access to the original code. That is probably just one reason why the new version took so long as its nearly 18 months overdue. Someone in the thread did mention that if NoMachine continued with some of the 3.x NX code that was GPL'd they would have to contribute back to the 3.x source any changes they make. But... all of the above may be nothing or just fodder for lawyers to make money arguing over. I think it would be worthwhile to post the question on the NoMachine forum as a question and get their official answer as it is a legitimate question that they must have decided on when they went closed-source for the 4.x release of NX. I'm probably the right person technically to ask the question or name what modules etc but perhaps someone on the list could and let us know their answer. Just a thought. Brian

NoMachine's licensing
by brian mullan 03 Feb '11

03 Feb '11

I asked nomachine and here is their actual license. As I'd suspected the GPL components that they use NoMachine points out were GPL already and nearly 80% of the overall NX project. Given that I'm not sure they can copyright those modules as they were based on other GPL projects... see URL: http://www.nomachine.com/ar/view.php?ar_id=AR10B00018 Under the NoMachine EULA <http://www.nomachine.com/licensing> it limits their copyright to the following programs: *4.1 Commercial NoMachine Software NoMachine Commercial Software consists of the following computer programs that have been developed by NoMachine: - nxserver - nxnode - nxmanager - nxclient - nxapplet - nxstat NoMachine owns the copyrights and intellectual property in and to each item of NoMachine Commercial Software.* The EULA also names all of the Open Source NoMachine programs separately that remain open. The URL that Erik provided says: Note also that to maintain the code ununcumbered of copyright, patents and licensing issues, it is required that you agree on giving to NoMachine a *Joint Copyright Assignment, granting the right to use your contributions in future NoMachine software, being this future software open or closed source and intended for commercial or non commercial use*. Such a JCA is standard in the industry, being required, for example, to contribute to Apache or to some projects sponsored by the GNU FSF. While *NoMachine releases its OSS software under the GPL license (a non-whitdrawable deal, ensuring that the software you contributed will be freely available forever under the terms of this same license*),* it is a requisite that NoMachine will maintain the full copyright on the software it develop*s. So any code anyone's contributed since 2004 to NoMachine's programs (see the above list) just gives NoMachine JOINT copyright with the contributors. There's only a question if any of x2go's current modules were directly derived from NoMachine's above "programs": libssh nxcomp nxcompext xcompshad nxproxy x2goagent x2goclient x2gognomebindings x2goplugin x2goserver Brian *Article: #AR10B00018* Added on: 2004-10-04 Last Modified: 2011-01-12 Applies to: NX Licensing *Under what kind of license is NX distributed?* NX Server and NX Client are commercial products, distributed under a closed source licence <http://www.nomachine.com/licensing> but all the core libraries (for example libraries implementing X protocol compression), the modified X11 transport libraries (which implement proxying of any standard X client) and the NX agent (the program that runs X sessions on behalf of the user) are released under the GNU General Public Licence.

They have the copyright on all code in NX, see their contribution guidelines: http://www.nomachine.com/ar/view.php?ar_id=AR12B00113 To spell it out: Nomachine can relicense the NX code any which way they want.

Hi Mike, as there now is an "official" git repo. What shall we do with the work we did? There was quite a bit of dependency-cleanup and build fixing involved to get things running at launchpad. Shall we mail the patches to the mailing list or will you pull them from our server? Or do you rather want the patches sent to another mail address? Cheers Morty -- Dipl.-Ing.

SSHFS and Permissions
by --[ UxBoD ]-- 31 Jan '11

31 Jan '11

Hello all, I have been working on making removable media available to Windows via a Samba share and hit a very strange problem. When you initially save a file to the share it would complain about having insufficient permissions, though if you were to save it again straight away it would work. The problem has been tracked down to how the SSHFS is mounted from within x2gomountdirs. The original command was: sshfs -o ServerAliveInterval=300,Cipher=blowfish,IdentityFile=$key,UserKnownHostsFile=$key.ident $user\@$host:\"@dirs[$i]\" \"$mntpath\" -p $port 2>>~/mounts.log for which I have changed it too: sshfs -o uid=$uid -o gid=$gid -o ServerAliveInterval=300,Cipher=blowfish,IdentityFile=$key,UserKnownHostsFile=$key.ident $user\@$host:\"@dirs[$i]\" \"$mntpath\" -p $port 2>>~/mounts.log with those two new variables being set via: my (undef,undef,$uid,$gid) = getpwuid($<); and the resulting mount have the ownership of the users primary id and group. Is there any reason why this approach was not used ? or it worked quite happily as the mount is 777 anyway ? -- Thanks, Phil

X2go client window in rootless mode crashes when mouse is moved over title bar
by Mike Gabriel 31 Jan '11

31 Jan '11

Hi there, this issue has probably been already addressed: During development of PyHoca-GUI I encounter some weird behaviour on mouse moves that cross the title bar of a rootless session window (e.g. xterm via X2go, but also any other app). I think that this problem only occurs with the initial rootless window (e.g. xterm). Any subsequently started application window has not shown this behaviour so far. Yesterday then, I found an article on the NoMachine site that might well relate to the problem: http://www.nomachine.com/ar/view.php?ar_id=AR06H00567 Question at Heinz+Alex: is this referred to functionality part of the x2goagent code? Is it possible to disable it? I could at the x2goagent sources, but my C++ capabilities are to weak to dig through that... Also refer to this posting which points out that the named functionality must be found somewhere in x2goagent: http://www.nomachine.com/fr/view.php?id=FR06D01396 Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

28 Jan '11

Since there is a discussion on this topic... *Launchpad <https://launchpad.net/>* would seem to be a reasonable fit for hosting the x2go project as there are over 20,000 projects hosted on Launchpad already? Launchpad provides: - *Bug tracking* <https://bugs.launchpad.net/> - *Code hosting* <https://code.launchpad.net/> using Bazaar< http://bazaar.canonical.com/> - *Code reviews* <https://help.launchpad.net/Code/Review> - Ubuntu package building and hosting <https://launchpad.net/ubuntu> - Language Translations <https://translations.launchpad.net/> - *Mailing lists* <https://help.launchpad.net/Teams/MailingLists> - *Answer tracking and FAQs* <https://answers.launchpad.net/> - Specification tracking <https://blueprints.launchpad.net/> Click here for their tour <https://launchpad.net/+tour> I think it would be very suitable for all debian related distro users.

can't start ssh tunnel / integration with existing ldap
by Martin Steigerwald 26 Jan '11

26 Jan '11

Hi! I installed X2goserver one into a Debian Squeeze VM under VMware ESX today. Since we use a LDAP server to central user management I integrated it via libpam-ldap and libnss-ldap manually. We also use NFS for home directory so I added that too. Logging into the server via SSH works as expected. But I get "can't start SSH tunnel" when trying to open a new X2go session with x2goclient. When I use a SSH key I get messages like this: Verbindung fehlgeschlagen intraws.of.teamix.net: Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Permission denied, please try again. Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Permission denied, please try again. Unable to connect: /home/ms/.x2go/ssh/socaskpass-M31562 Permission denied (publickey,password). I guess this has to do with the usage of NFS. ~/.x2go/ssh is 750 and root is squashed to nobody:nogroup. Thus it is neither the user nor the group. Since chmod 777 ~/.x2go/ssh fixes key based login for me, it seems that something of x2go server is using root privileges to access files in the home directory of the user. Could this be changed to use user rights - root can su to any ? This would work with NFS. Other questions: 1) Can X2go client be told to use an existing ssh agent which has the right identidy added? A ssh user@intraws works already without asking for the key password, thus if x2goclient uses this ssh-agent it wouldn't need to ask for the passphrase as well. 2) What steps are necessary to integrate x2go with an *existing* LDAP server? x2goldaptools depends on slapd and samba and since we use NFS with an existing LDAP server I want neither of those. LDAP authentification via PAM works already. I can login with SSH and LDAP password of a user. I thought this would be enough for x2go *when* users that use x2go are in the group x2gousers. They are. But in the local group. What additinional steps are necessary? Ciao, -- Martin Steigerwald - team(ix) GmbH - http://www.teamix.de gpg: 19E3 8D42 896F D004 08AC A0CA 1E10 C593 0399 AE90

Re: [X2go-dev] X2Go Client
by Joachim Langenbach 25 Jan '11

25 Jan '11

Good Afternoon, I've created a small patch (Version 3.01-5, don't know which is current version) to integrate the first features of the system tray stuff. Currently this features of the list are supported: * Auto minimize to tray after established the connection successfully * Open the normal client > * Auto minimize to tray after established the connection successfully (and > / or start already minimized?) > * Options right clicking on the tray icon: > * For each active connection: > * Close > * Pause > * Make directory available (In german version it is called "Ordner > freigeben") > * Start a new connection > * Open the normal client The patch includes some commented lines, they can be uncomment to display a standard message on minimize to the tray on first minimization. Therefore the system tray stuff can than be turned on by default (which is propably wanted by most users). Right now, system tray is deactivated and must be enabled at the ConfigDialog.

x2go not working on ubuntu 10.10

As mentioened in a separate email I have EC2 Ubuntu 10.10 servers running x2go and they work fine. I also provided you my phone number. I'm not sure what you are doing wrong or are not doing but what you are trying to do is fairly easy. Send me an email with the AMI # you are using for the EC2 image. I'll take that AMI, start an instance, install x2go server on it and try to log into it myself.

Hi, I tried to get this working all night, but it seems there is no way to connect to an ubuntu 10.10 installation using x2go (package x2goserver-home).

x2go thin client session configuratino
by Neil W. Hunt 23 Jan '11

23 Jan '11

Hello, I have setup the x2go thin client environment. However, I'm having a few issues: 1. Sometimes the netboot process stops at the terminal login prompt and doesn't boot all the way into the x2goclient. How is the auto-login happening when it DOES work? Why would it be stopping sometimes at the login prompt and other times booting straight into the desktop client? Is the process run by a particular user? 2. When it is booting up into the fullscreen x2go client, anytime I try to make a session, it doesn't save the changes I make, thus I obviously can't login to a particular server. I put a video of the problem at http://10addyrd.com/x2gotc.mov 3. Is there a way to prepopulate a session for users? Where is the .x2goclient/sessions file stored that is used by x2goclient in a thin client setup?

x2go-users vs. x2go-dev list
by Mike Gabriel 21 Jan '11

21 Jan '11

Dear list, I notice that some of the recent discussions on X2go-dev are actually X2go-user issues. For these issues we have set up the mailing list: x2go-users(a)lists.berlios.de I also have sent some of the PyHoca-GUI announcement mails to x2go-dev which might be more appropriate on the x2go-announcement list, though Python X2go is still in alpha state and the mails are mainly meant as calls for testers. However, make sure to stay also tuned with announcements: x2go-announcement(a)lists.berlios.de Maybe (a) people on X2go-dev can make sure to be subscribed to X2go-user and X2go-announcement (if they are interested in these issues), so that people do not feel that the X2go geaks are only listening on x2go-dev (b) we all become more disciplined when choosing a channel of communication. I quite fancy the idea to get away from spamming the X2go-dev list with every topic available. Please keep this channel free for development and development-related security issues. For installation problems and other issues that occur while using X2go please use the X2go user list. I personally will ignore user issues posted to X2go-dev in the future, but will try to contribute as best as possible to solutions on X2go-user. Here again the links for mailing list subscription: <quote> https://lists.berlios.de/mailman/listinfo/x2go-announcement https://lists.berlios.de/mailman/listinfo/x2go-user https://lists.berlios.de/mailman/listinfo/x2go-dev </quote> Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

x2go not working on ubuntu 10.10?
by jmm 21 Jan '11

21 Jan '11

Hi, I tried to get this working all night, but it seems there is no way to connect to an ubuntu 10.10 installation using x2go (package x2goserver-home). When trying to connect, x2goagent is complaining about not being able to open a display (in the session log). The machine is an Amazon EC2 instance, which has no video card. I suspect this is causing the trouble. I have read it was working on ubuntu 10.04 by the way, as in http://blog.restbackup.com/how-to-use-amazon-ec2-as-your-desktop I also tried freenx, neatx and nxserver (from nomachine), and they all give similar errors. Tightvncserver on the other hand does work, maybe that's not so useful information, but just in case. The server log says: $ cat session.log /usr/bin/x2goagent: line 1: -e: command not found NXAGENT - Version 3.4.0 Copyright (C) 2001, 2007 NoMachine.

Re: [X2go-dev] x2go not working on ubuntu 10.10?

Things I tried, but did not work: - check if user is a member of "x2gousers" group in /etc/group - check if user is a member of "fuse" group in /etc/group - reset password of user to make sure not entering wrong password - set DisallowTCP to false in /etc/gdm/gdm.schemas - remove "-nolisten tcp" from /etc/X11/xinit/xserverrc - run the command `xhost +x` (from the command line it gives an error "xhost: unable to open display """ caused by no active display (and therefore no $DISPLAY environment variable), so I also tried entering this from within an VNC session and the command completed normally, also tried this with an Xvfb xsession) - allowed login with passwords in /etc/ssh/sshd_config - restart ssh service - restart EC2 instance - tried installing packages x2goserver-home, x2goserver-one, x2goserver (and removed installations between trying different packages) When I tried different NX servers, I always used the corresponding client (I have been careful not to mix up different clients with different servers). For x2goserver I am using x2goclient from the repository, I am using it on Ubuntu 9.04 desktop 64-bit edition. My settings are: name: test hostname: <EC2 public dns here> login: ubuntu ssh port: 22 use rsa/dsa key for SSH connection: <tried different settings, tried to leave it empty, tried the key I got from amazon, tried a key which was sitting in ~/.ssh/id_rsa; tried all possibilities with and without password> session type: GNOME In all cases the error on the server stays the same. brian mullan wrote: > I've been using AMI's from Alestic or one's I build myself.

Fwd: X2go-dev Digest, Vol 25, Issue 20
by brian mullan 21 Jan '11

21 Jan '11

Ok VNC's working so you know there is a desktop capability on the server. But VNC's not using either the FreeNX, NoMachine NX or x2go "server". And I don't think you can use the x2go client to try to connect to either a FreeNX or NoMachine NX server so if you were trying to connect to them. What client are you using linux, windows, mac? And on the x2go client did you pick Gnome desktop or KDE to match whichever your server desktop is? Ubuntu would be Gnome by default but x2go defaults to KDE. Since its not working anyway... maybe you should uninstall the x2go server on your ec2 instance then reinstall the x2go server using the instructions found here<http://wiki.x2go.org/installing_x2goserver-one_debian> .

New thoughts on Git in progress...
by Mike Gabriel 21 Jan '11

21 Jan '11

Dear x2go-dev folks, I just talked to Heinz on the phone and we have taken your criticism on the current/new Berlios Git into a new course of discussion. Similarly to some of you, our Debian Developer in-spe has had quite some criticism on the current Git structure. To support Debian development and packaging of X2go as best as possible we will discuss a revisioned structure for X2go Git, which will probably also include a change over to another hoster. As this discussion takes place between at least for people, please allow us some time to for the current internal discussion on this topic. There will hopefully be some results around the next weekend... light+love, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0x1943CA5B mail: m.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

VirtualBox or KVM and x2go from Mac
by Florian Effenberger 21 Jan '11

21 Jan '11

Hi, sorry for spamming this list, but I'm in the progress of setting up an internal Document Foundation x2go server. :-) I am having issues when using LXDE as desktop environment to control VirtualBox or KVM (virt-manager) with x2go from Mac. Only some commands seem to work -- if I boot e.g. Ubuntu in the virtual machine, only page up works, but enter and page down to nothing in the graphical GRUB boot menu, so the machine is unusable. I also tried changing the keyboard settings in x2go client, to no avail. The same server works just fine with the x2go client from Windows 7. If I can be of any help in debugging, let me know ;) Florian

x2go not working on ubuntu 10.10?
by jmm 21 Jan '11

21 Jan '11

Hi, I tried to get this working all night, but it seems there is no way to connect to an ubuntu 10.10 installation using x2go (package x2goserver-home). When trying to connect, x2goagent is complaining about not being able to open a display (in the session log). The machine is an Amazon EC2 instance, which has no video card. I suspect this is causing the trouble. I have read it was working on ubuntu 10.04 by the way, as in http://blog.restbackup.com/how-to-use-amazon-ec2-as-your-desktop I also tried freenx, neatx and nxserver (from nomachine), and they all give similar errors. Tightvncserver on the other hand does work, maybe that's not so useful information, but just in case. The server log says: $ cat session.log /usr/bin/x2goagent: line 1: -e: command not found NXAGENT - Version 3.4.0 Copyright (C) 2001, 2007 NoMachine.

X2Go Client
by Joachim Langenbach 20 Jan '11

20 Jan '11

Good Afternoon all, I've used X2Go for a while now and have another suggestion to improve the usage of the client. It would be really nice, if the client window will be closed or minimized to tray (Quite easy with Qt) after establishing the connection. The window is more or less useless during the session usage but consumes space at the taskbar. Kind regards, Joachim Langenbach

Port conflict when using x2go client och x2go server
by Daniel Lindgren 15 Jan '11

15 Jan '11

Hello. I've run into a problem when using x2go to remote control a server which in turn remote controls another server using x2go, i.e. client_a -> server_a -> server_b. I can create the sessions without problem, but I can't reconnect to server_a if I suspend the session. I get an error message about "the remote proxy closed the connection while negotiating ...". As far as I can see there is a port conflict. Ssh on client_a forwards local port 30001 to/from sshd on port 30001 on server_a, which in turn has an ssh that forwards local port 30001 to/from sshd on port 30001 on server_b. I've worked around it by manually changing SSH_PORT range in /usr/bin/x2gostartagent on server_b to start at 30100 (i.e. a different range than server_a uses). I don''t know the inner workings of all x2go components, but by studying x2goclient-cli I'm guessing that separating port ranges to use when forwarding would solve it permanently; instead of using "30001:localhost:30001" one would use "31001:localhost:30001", thereby separating ssh and sshd ports if they are running on the same machine. Cheers, Daniel

debian package issues
by Gertjan Halkes 14 Jan '11

14 Jan '11

Hi, After installing the x2goserver-one debian package (and dependencies) from x2go.obviously-nice.de on a completely fresh minimal debian Lenny install, I could not get a session to start. After looking in <home dir>/.x2go/<session name>/session.log I found the reason: /usr/lib/x2go/x2goagent: error while loading shared libraries: libXcomposite.so.1: cannot open shared object file: No such file or directory After installing the libxcomposite1 package everything worked fine. So I guess there is a dependency missing in the x2goagent package. Secondly, I had a problem with the x2gocleansessions script that is run as part of the x2goserver service. It tries to use sudo to execute x2gopgwrapper. However, the sudo program uses the postinst script to set up the default /etc/sudoers file while x2goserver tries to add to the sudoers file in the preinst script. The result is that if sudo is installed as a dependency of x2goserver, the sudoers file _only_ contains the x2go lines, and not the default lines allowing root to do everything through sudo. Hence, root is not allowed to issue the x2gopgwrapper command through sudo. This can probably be repaired by moving the additions to the sudoers file into the postinst script, as this will get executed _after_ sudo is completely set up (sudo will make the default file in postinst as well). Also, you may want to add a separate line allowing root to execute x2gopgwrapper anyway, such that even if root is not allowed to do everything through sudo because the sysadmin for some reason didn't want it, x2go will still function as normal. Regards, Gertjan

restored pc but x2go is broken
by brian mullan 13 Jan '11

13 Jan '11

I had to restore an linux machine (ubuntu) from backup. However, after the restore x2go is no longer working correctly. Using the x2goclient I try to log into an x2go server machine but the response is almost immediately a message "Finished" and the x2go client session window reappears with the login/password entry fields. If I log-in again x2goclient tells me there is an existing session - so it seems 1st attempt did start the session connection. I know there are some log files I can look at to get a clue what is wrong but I couldn't find any documentation about what logs and where. fyi. I've tried purging the x2goclient and reinstalling but the results are the same - re getting the "Finished" message even though it looks like the session did get established. Any tips/hints to troubleshoot this would be appreciated. Thanks. brian

Any pointers on using x2go with chroot?
by Paul Clark 13 Jan '11

13 Jan '11

Hi All, I'm having trouble connecting to a chroot user. Here's the error: 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. I'm not sure what I should do to attempt to fix this. Hope someone can help. Cheers, Paul. PS: If it is relevant, I initially set up a chroot environment with jailkit for NX as per here - http://www.nomachine.com/ar/view.php?ar_id=AR09D00419 - but it gave a wrong subscription error.

Windows 7 and libssh
by --[ UxBoD ]-- 12 Jan '11

12 Jan '11

Hi, I am compiling up the x2go client to use vcxsrv on Windows 7 which worked fine. Though when I run the 3.0.14 libssh version it hangs on connecting. I thought it could have been my compilation for which I tried the standard installation and that does exactly the same. If I then kill the client using the red X in the corner I receive a dialogue box with a message from sudo asking if I have had the risks explained to me :) Is anybody else this type of behavior ?? -- Thanks, Phil

Dear X2go community, today I have added i18n support to PyHoca-GUI. A German translation is already available in SVN: https://svn.das-netzwerkteam.de/x2go/pyhoca-gui/trunk/po/de.po The dutch translation will probably be done by Dick Kniep from Lindix in the Netherlands. My question: are there people on this list who volunteer in doing other translations? There are currenlty 159 i18n-tags waiting translation per language. I would be really very grateful if people on this list would pick up on this job. Of course, once you have raised your hand as a i18n maintainer, I will contact you on outstanding updates in regular intervals. Looking forward to community cooperations!!!

X2go windows client trouble
by administrateur＠teleadmin.com 11 Jan '11

11 Jan '11

Hi In a first time , i must thank you for yours works . I am really happy to found X2GO project . Exactly what i was looking for ... but ;) I experiment some bugs from the windows client tested with x2goclient-3.01-4 to 13 (release 14 just crash at start on my seven64). I am shure the bug is due to the way i intend to use the client. Let's me explain ;) i do this before with xming (its works but it was slow). I define single application that start the command /usr/bin/gnome-panel. In that's way the gnome panel start and you can use linux seamlessly inside you windows desktop ... even linux apps go in the windows taskbar ... ;) Perfect .... but sometime (try 20 seconde moving your mouse on the menu) when i let's my mouse move on the gnome-panel menu the x2go connection crash. I am frustrated because exepting that random big trouble , it's just perfect. Of course i have try connect normally or even custom desktop with /usr/bin/gnome-panel command and there is no bug. Inside xming wizard there is a launch command for multiple windows (the way i was doing my trick sucessfully before with xming). And the parameter single application is "single" ... ;) Maybe a new skill as define connection for starting a multiple windows command as /usr/bin/gnome-panel. if it's the trouble. you can easyly test and reproduce it. I am shure you will understand how it could be great to start gnome-panel and use linux seamlessly inside windows ... Other subject : I can only use basic image or .JPG compression but nothing else ? jpg works fine but when you see rdp ...;) for my test i have use the client you know and stable and unstable release of the server. Its just does not changing any compression protocol ability or connection trouble. Sorry for my english best regards, romain

Problem with initial user configuration on Ubuntu
by Jeff Hanson 10 Jan '11

10 Jan '11

If a new user is created on Ubuntu (with users-admin or adduser), and the initial GUI login is performed with X2Go, the default XDG directories (as defined in /etc/xdg/user-dirs.defaults) are not created. I'm not sure what script or tool is supposed to handle that but it's either not executing or failing.

X2go Git now available at BerliOS
by Mike Gabriel 10 Jan '11

10 Jan '11

Dear X2go-folks, the X2go Git repository at BerliOS has been set up today. You can browse the X2go-Git at BerliOS: http://git.berlios.de/cgi-bin/cgit.cgi/x2go/tree/?h=master http://git.berlios.de/cgi-bin/cgit.cgi/x2go/tree/?h=develop META INFORMATION ================ The master branch is the project's release branch. A commit to master will be equivalent to an X2go release. The develop branch will be the branch that you can derive your own branches from for features you want to implement (and possibly propose for integration into X2go). Currently, the develop branch is a simple copy of the master branch. Heinz and Alex have just finished a complete rewrite of the x2goclient that will use libssh as opposed to ssh binary calls in the background. Alex has proposed a patch to upstream libssh that got accepted and once the new libssh version is released there will be a commit to the develop branch containing the latest x2goclient code. This is expected for the end of January 2011. We are also still discussing the Git branching model details. As a template for the discussion we use this document (as proposed by HedgeHog from the x2go-dev list): http://nvie.com/posts/a-successful-git-branching-model/ There will be some slight modifications to this model but the discussion will take place along this very fine piece of work. USING X2go/Git: =============== You can anonymously clone a working copy of X2go Git with this command: $ git clone git://git.berlios.de/x2go x2go BerliOS users should also be able to clone a working copy with this command: $ git clone ssh://<developername>@git.berlios.de/gitroot/x2go x2go If you want to branch off of the develop branch for your own implementation work, then do this after having cloned the BerliOS Git: $ cd x2go $ git checkout develop $ git checkout -b branch_<featurename> ... where <featurename> is a short string of your choice (at least for now) that describes the feature you are going to implement. If you intend working on a feature that you would like to become part of X2go some time in the future then we should agree on some, e.g.: 1) please talk to Heinz and Alex about your ideas first, don't simply start working 2) make sure that you work in small portions, do not rewrite the complete code and expect a merge 3) document your work 4) ... ??? ... For now, feature branches will stay on your local file systems. Once, we have finished our discussion on the Git branching model we will inform you on how merge requests can be send to the project (probably via a commit of your feature branch to BerliOS, but we will see...). Looking forward to a growing project and an active X2go community with lots of fine contributions... light+love, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0x1943CA5B mail: m.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Hardware requirements
by brian mullan 07 Jan '11

07 Jan '11

Joakim If you haven't read this yet off of the old x2go website you might want to read about how Linux4Afrika Project<http://www.linux4afrika.de/x2go/basic_installation.html>configured their x2go servers. That web site and information is a bit "dated" but it can give you some ideas. One thing caught my eye in your email are a couple of your statements: "the setup will serve 200 x2goclietn users on a wlan" If the goal is to support 200 simultaneous users... I'm not sure those 2 servers can do that. But if its just to support 200 accounts with some portion of those logged in at any one time then it can work but will still need some sanity scale testing by yourself to know how many at any one time can be logged in. Second, over a wan you don't say what kind of bandwidth your WAN has. So basic questions will be what is bandwidth of WAN link to the site or sites. How many users would be on each of those WAN links sharing that bandwidth. Keep in mind no NX technology whether x2go, NoMachines NX or anyone else can defy physics so the size and number of Servers has to be in line with the number of users and the load represented by the x2go server as well as any APPs they run. The number of users will be limited at any one time to the bandwidth of your WAN link and the capabilities/size of your servers (cpu, memory, disk i/o, network i/o). ---------------------------------------------------------------------- Message: 1 Date: Wed, 05 Jan 2011 14:00:49 +0100 From: Joakim Seeberg <kontakt(a)seebergit.dk> To: x2go-dev(a)lists.berlios.de Subject: [X2go-dev] Hardware requirements Message-ID: <4D246B81.3060702(a)seebergit.dk> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi, could someone elaborate on the hardware requirements for x2goserver setup.

Does the load spread automaticly or will the user have to choose server at login, when using x2goserver with more than one node? Thanks, Joakim ------------------------------

Re: [X2go-dev] x2goclient-cli don't terminates correctly?
by Daniel Lindgren 07 Jan '11

> A quick and dirty solution would be to fix the perl script to take care of child processes and properly terminate them at exit. ... and here's my quick & dirty hack, add it after the last line in x2goclient-cli: # ---- CUT ---- my @SSHS = (); my $ssh; my $pid; my @ssh_split = (); # print "$0: Checking ssh sessions ...\n"; open(GR_SSH,"ps ux | grep \"ssh -p $port .*-N -L $gr_port:localhost:$gr_port $user\@$server\" | grep -v grep |"); @SSHS = <GR_SSH>; close(GR_SSH); if ($sound) { open(SND_SSH,"ps ux | grep \"ssh -p $port .*-N -R $snd_port:localhost:$snd_port $user\@$server\" | grep -v grep |"); push(@SSHS,<SND_SSH>); close(SND_SSH); } if (scalar(@SSHS) > 0) { foreach $ssh (@SSHS) { $ssh =~ s/\s+/\|/g; @ssh_split = split(/\|/,$ssh); $pid = $ssh_split[1]; # print "$0: Ending ssh session with pid $pid ...\n"; system("kill -1 $pid"); } } else { # print "$0: No ssh sessions found.\n"; } # ---- CUT ---- Don't know if there's a permanent solution in the works, the above hack should do the job until then. While testing I noticed that there are no hanging tunnels if I use SSH keys to authenticate (http://wiki.x2go.org/passwordless_authentication_using_ssh-keys) if you don't want to modify x2goclient-cli that might be a workaround.

.xinitrc and .xsession

Hello, I'm currently struggling with LXDE to get it localized into German on an English system, which seems to require exporting LANG= into the X session. Nothing works so far, so before I investigate further, a maybe dumb question: Are .xinitrc and/or .xsession used at all when using x2go, or is a different file kicking in then? ;) Thanks, Florian

PyHoca-GUI v0.0.18 released for testing (using Python X2go 0.0.28)
by Mike Gabriel 31 Dec '10

31 Dec '10

Dear list, I have just released another test version (v0.0.18) of PyHoca-GUI (a wxPython X2go client implementation for the systray). Debian (>=squeeze) and Ubuntu (>=lucid) packages are available for installation. Further information can be found here: http://das-netzwerkteam.de/site/?q=node/71 Changes / modifications / improvements since last announced release (v0.0.15): o greatly improved session management (X2goSessionRegistry class) -> which makes it possible to notify more properly about what happens to running/suspended sessions o added/enabled a session profile manager o added edit functionality for connected profiles o added local folder sharing while session is connected o added SSH proxy support (see below) o rudimentarily added XDMCP support (not yet fully working) o added command line option that make PyHoca-GUI portable (esp. interesting for Windows version which will be available soon) o added Xserver support for Windows version The SSH proxy feature: ---------------------- As it was a customer request and also something I need regularly I implemented a SSH proxy server feature into PyHoca-GUI. What it does is this: 1. create a forwarding tunnel to some well protected host via my server: ssh -lmike myserver.local -L 54321:host.reachable-through-VPN.via.myserver:22 2. then connect an X2go session to myserver.local:54321 in order to reach the highly protected server at the end of the above SSH tunnel. SSH proxy support adds for new options to the sessions file: usesshproxy=true|false sshproxyhost=<hostname>:<port> sshproxyuser=<username> sshproxytunnel=<loca_host>:<local_port>:<remote_host>:<remote_port> SSH proxy support, of course, is implemented with Python Paramiko. The SSH proxy settings can be editor for each sesson profile under the ,,Connection'' tab. I have tested configuring SSH proxy quite a lot with PyHoca-GUI and x2goclient-qt. Both apps use the same sessions configuration file and the above options persist well when editing session profiles with either of the GUI applications (PyHoca-GUI known how to interpret them, x2goclient-qt simply ignores them). @Heinz+Alex: I was quite happy to see that x2goclient-qt ignores unknown session options and leaves them also untouched when editing a session profile. PyHoca-GUI also does this with session options it does not know. Thus, it is possible to add session profile options to the sessions (or GCONF or WINREG) file without the clients interfering with each other's ,,special'' options. light+love and happy new year (soon!!!)

documentation fixes
by Florian Effenberger 30 Dec '10

30 Dec '10

Hi, I would recommend some changes to the documentation: - When using a SSH key, the passphrase (at least on Mac) is not stored by the system's SSH agent, but it looks like the key password has to be entered into the password field in x2go. Took me quite a while to figure out. ;-) - For installing the package key on Ubuntu and probably Debian, the following command is easier than the one in the documentation: apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C509840B96F89133 - For adding the apt archive, I recommend using echo "deb http://x2go.obviously-nice.de/deb/ lenny main" >> /etc/apt/sources.list.d/x2go.list instead of adding to sources.list directly.

Mac client can't find X11 sometimes
by Florian Effenberger 30 Dec '10

30 Dec '10

Hello, I have the issue that the Mac client can't find X11 sometimes. X11 is configured accordingly with accept network connections and safe connections, and sometimes it works, but sometimes x2go says it can't connect to X11. Restarting x2go, even logging in and out doesn't help. I tried deleting ~/.x2go and ~/.x2goclient and .Xauthority, to no avail. Only rebooting cured the problem. Maybe the problem lies deeper. Although I installed XQuartz, rebooted the machine so XQuartz is default over X11, and also manually chosen XQuartz in the x2go client, the original Apple X11 client is launched all of the time. Anyone can give me an advice on how to debug the problem? ;) Thanks, Florian

plugin install issues on Windows
by Gerry Reno 27 Dec '10

27 Dec '10

Hope everyone is having nice holidays. I tried installing the Windows plugin (3.01-11) today on a few machines (Windows XP). The 32-bit Windows plugin installs fine but just shows a black screen on every recent Firefox version. What's funny is I've installed this a number of times on Windows XP and it always installed and ran (although with mouse issues). But now, the plugin just gives a black screen. Has anyone figured out the right voodoo to get the plugin installing reliably on Windows? Regards, Gerry

x2gothinclient boot error
by Neil W. Hunt 27 Dec '10

27 Dec '10

Hello, I am attempting to load the x2gothinclient system. I have the client booting from the network via DHCP and starting the x2gothinclient as per the instructions on the website. However upon startup I am getting an error: Begin: Mounting root file system /init: .: line 171: can't open /scripts/NFS [] Kernel panic - not syncing: Attempted to kill init! Any ideas? I have boot=nfs, but is there something else I might be doing wrong?

Need a preseed option in deb files for sudoers entries
by Jeff Hanson 22 Dec '10

22 Dec '10

The preinst scripts in both the x2goserver and x2goprint debs add sudoers entries. When adding the packages to an existing installation this is adequate (although it may violate a Debian packaging policy somewhere). If the packages are installed during a Debian/Ubuntu installation using kickstart and/or preseeding it causes a conflict. The problem is that the entry "%admin ALL=(ALL) ALL" is added after the installation/post-script stage. If x2goserver or x2goprint is installed, their NOPASSWD entries are already in sudoers and the %admin entry overrides them since the file is processed from top to bottom. This causes x2go connections to fail with "sudo: pam_unix(sudo:auth): conversation failed" and "sudo: pam_unix(sudo:auth): auth could not identify password for [user]" errors in auth.log (an infinite number as it really doesn't want to give up until I kill x2gostartagent). Preseed options/templates need to be added to these debs so that the sudoers entries can be skipped via preseed/debconf and added later by a late_command script or manually after installation.

X2GO and SSH
by --[ UxBoD ]-- 22 Dec '10

Hi, would you have any details on how you compiled OpenSSH for Windows please ? We are experiencing an issue we believe may be due to the age of the distributed SSH client and would like to update it to the latest release. -- Thanks, Phil

git repository status, cloneurl?
by snalwuer＠cip.informatik.uni-erlangen.de 20 Dec '10

20 Dec '10

Hello, Sorry if I'm bugging you with this... I'm interested in changing some code in x2go and of course commiting those changes back. Because it would make things easier, I would like to ask about the state of the official git repository? Is there a 'git-clone'-able official tree somewhere I can base my changes on? Greetings, Alexander Wuerstlein.

Re: [X2go-dev] x2go with likewise-open (ldap) questions
by Neil W. Hunt 20 Dec '10

Ivan, Thanks, I really appreciate your suggestions. ********************* >Please, provide more information about all versions that you use. For >example, I'm using X2goclient 3.01-13 under Windows7 as client, because the >latest version 3.01-14 doesn't work. I am using 3.01-08 for Ubuntu as client. This is the one that downloads by default from the debian library. I have also tried it with 3.01-04 for Windows and for Mac, but same results. I will try 3.03-13 and see if there are any differences, but I doubt it. ********************** >1. Change your ssh logging by changing inside file: /etc/ssh/sshd_config - >LogLevel INFO change to LogLevel DEBUG3 >Then watch the authentication log: tail -f /var/log/auth.log .And login again >(I know that you said that it authenticate successfully, still check this out) I changed this and now have more info. I still cannot see any differences in the login messages between the two messages. I tried attaching each log file, but the list said I needed approval to send something with attachments of 200K. ******************* >2. Login locally on the Ubuntu server with: USERNAME@DOMAIN (although you >can't see them through gdm or kdm), if you can successfully login to the >domain locally. If you have troubles with that, then the problem is with >likewise. BTW, are you using likewise-open? How you've configured it? Using >domainjoin-gui? Can you see from System -> Administration -> Active >Directory Membership. (You can see that with Local user of Ubuntu). I can login locally as a LW user no problem, it shows the full gdm desktop. I am using Likewise-Open 6.0 and joined using domainjoin-gui ******************* >3. Try to login with SSH client (like putty for windows) using again >USERNAME@DOMAIN, and the password. Then check if this login is successful. Have done this as well and there are no issues, perfectly successful login as a LW user. ***************** >4. If authentication is good, but there is blank/black screen, then try >another: OS, Client, Client version. As I said above, the latest version >doesn't work in my scenario. Hint: Don't try to connect with client from the >same server, as it is not possible. If you use Windows, try to find other >OS, install other (virtual if possible) Windows, Linux, whatever is easy for >you. Again, I have tried it with clients on Linux, Mac, Windows, all the same result: full GDM desktop with audio for local accounts, blank screen (but all successful messages in the log) for LW/LDAP users. ************************ BTW, as I'm fearing that if/when I get this issue resolved with the black screen showing up, that I will then have the audio problems, I will add these comments: -I have Likewise Open setup to connect to our domain as the Default Domain, thus all of our uid's do not use the format DOMAIN\user. Before, we all used these IDs, but since we currently only have one domain, I have set LW to use the default domain and so now we can login with just "user". This also affects our directories and thus my .x2go sessions look like: /home/local/DOMAIN/nwhunt/.x2go/C-nwhunt-51-1292422868_stDGNOME_dp32 rather than /home/local/DOMAIN/nwhunt/.x2go/C-DOMAIN\nwhunt-51-1292422868_stDGNOME_dp32 And within that directory are indeed the pulse audio files you mentioned were NOT there when you included the ~/.x2go/C-DOMAIN\userid-.... .pulse-client.conf .pulse-cookie I will report back if I find anything more.
