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

PyHoca-GUI for Windows
by Mike Gabriel 19 Jan '11

19 Jan '11

Dear x2go-dev people, here is a short mail to let you know, that there is the first Windows version (packaged by NSIS installer) of PyHoca-GUI. https://svn.das-netzwerkteam.de/x2go/pyhoca-gui/win32-dist/installers/setup… The Windows version has not been tested as much as the Linux version, please do only test it if you have some patience... For runtime errors check the file $INSTDIR\pyhoca-gui.exe.log and if possible report those to me directly. Greetings, Mike PS: There are also new Debian and Ubuntu packages available (pyhoca-gui=0.0.26, python-x2go=0.0.35) on deb http://packages.das-netzwerkteam.de/debian <distname> main deb http://packages.das-netzwerkteam.de/ubuntu <distname> main -- 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…

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
