x2goserver on SLES11
by uhaller＠kabelbw.de 06 Sep '11

06 Sep '11

Hi, I found your posts within the x2go wiki, thank you very much for providing the instructions for manual install from source tarballs. I would also like to switch from freenx to x2go, therefore I want to install the x2goserver on an SLES11 installation. I followed the instructions and completed setting up x2goserver on SLES11. Now I'm trying to connect to x2goserver via an x2goclient (X2Go Client V. 3.99.0.0 (Qt - 4.7.2)) on Ubuntu 11.04. When starting the session I'm getting following problem: "Authentication failed" - "Access denied. Authentication that can continue: publickey,keyboard-interactive" I'm able to connect via ssh. Do you have any ideas what might be wrong? It is possible to get more detailed information via special trace settings? Thanks in advance, Uwe.

On the x2go-user ML there is a discussion going on about margins and X2go printing. Do we want to look at that more closely???

Problems setting print system in x2go
by Mario OROZ 01 Sep '11

01 Sep '11

Hello, I'm new to the list. I use a server x2go on a Debian 6.0 with Windows XP clients. I do not understand how to set the printing to print on printers on the client side. I installed cups-x2go, and created a printer with cups cups-driver that provides x2go. I installed cups-x2go, and created a printer using the driver that provides cups-x2go. On the client windows, menu Option / Settings / Printing tab is checked the "Show this dialog Before start printing" Can anyone tell me of some howto or explain how to configure the local client printing from the server windows x2go Already, thanks

question regarding x2goclient armel builds
by Jimmy Knowles 31 Aug '11

31 Aug '11

Thanks for your work on the x2go packages. I was hoping someone could help me to be able to connect using the armel builds. I have a hp touchpad with x server running and a chrooted version of debian squeeze. I've installed the packages without any problems and I'm having some problems getting a session to start successfully. When I initiate a session from the touchpad, it will connect and the desktop displays, but any window manager items seem to crash. The panels don't display, any pop-up windows just flash and flicker. Only the desktop icons display correctly. And dmesg gives the following errors repeatedly: [65102.522642] metacity[5959]: segfault at 0 ip 00007f5d5e4e1ea1 sp 00007ffffb4ba480 error 4 in libXrender.so.1.3.0[7f5d5e4dd000+9000] [65102.523278] gnome-panel[5960]: segfault at 0 ip 00007fca77ca7ea1 sp 00007fff08238000 error 4 in libXrender.so.1.3.0[7fca77ca3000+9000] [65102.720377] trashapplet[5968]: segfault at 0 ip 00007fdb87f6fea1 sp 00007ffff313ec10 error 4 in libXrender.so.1.3.0[7fdb87f6b000+9000] [65103.621171] gnome-panel[5981]: segfault at 0 ip 00007f0211630ea1 sp 00007fffe7b2b790 error 4 in libXrender.so.1.3.0[7f021162c000+9000] [65103.622815] wnck-applet[5966]: segfault at 0 ip 00007fe8dac6eea1 sp 00007fffca25a130 error 4 in libXrender.so.1.3.0[7fe8dac6a000+9000] [65103.891078] metacity[5980]: segfault at 0 ip 00007f43eec66ea1 sp 00007fffff4193c0 error 4 in libXrender.so.1.3.0[7f43eec62000+9000] .

One difference that I notice is that the windows-initiated session name ends with dp32 (I'm assuming that's the color depth?) and the touchpad/armel-initiated session ends with dp24. Any ideas on how to get it to work correctly when initiating the session on the armel device? The server is running ubuntu natty, with version 3.0.99.5-0~49~natty1 of x2goserver. Thanks, Jimmy

x2goclient armel builds
by brian mullan 31 Aug '11

31 Aug '11

Mike Not sure if you remember but when I was trying to get PyHoca working on a chrooted Ubuntu environment on the nook color tablet I was also getting the RandR error in the logs. Initial authentication would work but before I'd see any remote display it would crash. My environment was an Android tablet, chrooted Ubuntu running LXDE so it was running Ubuntu's x-server at the time.

X2Go problem
by Christopher Stark 31 Aug '11

31 Aug '11

Hi, I've installed x2go on both my client pc (Kanotix/Debian Stable) and my server (salineOS / Debian stable) I configured my router with a dyn-dns adress and a port forwarding to my server but cannot login with remote from my client PC. When I try x2go freezes or I get this message: *Host key for server changed.* *It is now: 4c:53:xxxxxxxxxxxxxxxxxxxxxxxxxxxxx* *For security reasons, connection will be stopped* It has worked before but now it doesn't anymore. I reinstalled the Linux on my server maybe this is the reason? Could anybody here help me with that problem? best regards Christopher

x2go - Ubuntu 11.04 - Keyring problems
by Ralf Moll 30 Aug '11

30 Aug '11

Hi, I "upgraded" my pc from Debian Lenny to Ubuntu 11.04. Hmm, it cuts both ways..... Now every time I connect to my Ubuntu-Server-Installation [1], gnome-keyring want to be unlocked after a few seconds, not matter if I use gnome or lxde as x2go-session. That would not be that bad, but I get disconnected, no matter what I type in! As already mentioned [2] the ubuntu keyring is buggy, but how can I get an useable x2goserver on 11.04? I did already kick off keyring and keyring-ssh-agent out of the start-programs (System->Preferences->Session->Start Programs), but this did not work. What will cause this behaviour? Does x2go use the ssh-agent on the server for ssh-tunneling? Here some more links, which could be interesting: * https://bugs.launchpad.net/ubuntu/+source/seahorse/+bug/67793 * http://live.gnome.org/Seahorse/SSHAgent cu, and thanks for x2go! Ralf [1] Server Ubuntu 11.04 x2goserver installed like http://wiki.x2go.org/adding_the_x2go_repository_ubuntu [2] Keyring Problem http://www.mail-archive.com/x2go-dev@lists.berlios.de/msg02451.html

x2goclient not mount the spool directory (Ubuntu 10.10)
by Mario OROZ 29 Aug '11

29 Aug '11

Helo guys. I'm trying x2goclient from Ubuntu (but the version Qt, where is the GTK version?) and I see that the print spool directory of the client is not properly mounted on the server. My server is a Debian 6.0 with x2goserver, from the corresponding repositories. I used the mount command to check the server as root, like said John Sullivan III I'm using the ppa repository (launchpad ppa: x2go/stable) to Ubuntu 10.10 Add the user to group fuse in Ubuntu 10.10. I do not see the fuse module loaded with lsmod but the command "sshfs usr @ server: dir local-dir /" works! Someone could indicate how to get sshfs to mount the client's spool diresctorio? Other questions: How to make the printer driver created with x2go, print raw? Without creating the postscript which then results in pdf, let me understand? Thank you. Mario

x2go sound on debian squeeze / SalineOS?
by Christopher Stark 20 Aug '11

20 Aug '11

Hi, I have a server running saline os (based on debian squeeze with xfce) and a client with kanotix (with kde4 and also based on squeeze). I tried to get audio from the server to the client but didn't succeed. I unlocked the audio ports in my router so it should work. Which Audio server would you suggest in my place and does anyone of you know by any chance how I could get sound? Best regards Christopher PS x2go is a great program. I really like it! -- www.neoliberalyse.de | www.klokunst.org | www.projektidee.org

Instructions for manual install from source tarballs on a less well-known distribution
by Ivan Kabaivanov 17 Aug '11

17 Aug '11

Hi all, I would like to switch from freenx to x2go, but I don't use a well known distribution. I have LFS, Linux From Scratch -- a source based distribution. I'm following the instructions from http://wiki.x2go.org/installing_x2goserver_tarball and INSTALL from the x2goserver tarball. but I fail to get it to work. Firstly, the server dependencies are listed as: perl-suid lsof openssh-client openssh-server libconfig-simple-perl makepasswd libdbd-pg-perl libdbd-sqlite3-perl xauth I've installed everything except for perl-suid as this is no longer part of recent perl versions. Not sure how critical this is. Then, I follow the installation details from x2goserver's INSTALL: ========== BEGIN QUOTE ============ TARBALL INSTALLATION OF x2goserver ================================== 1.) USER + GROUP for X2go ------------------------- Set up x2gouser account and its group if they do not exist already: $ addgroup --system x2gouser $ adduser --system --no-create-home \ --disabled-password --disabled-login \ --shell /bin/false --group --home /var/lib/x2go x2gouser 2.) INSTALL x2goserver FILES ----------------------------- Extract tarball and run $ make install in base folder of the extracted tarball. 3.) SUID GROUP -------------- Configure ownership, permissions and setuid user bit of x2gosqlitewrapper: NOTE: The described action have already been performed by the Makefile run, leaving this here for documentation only. $ chown root:x2gouser /usr/lib/x2go/x2gosqlitewrapper $ chmod 2755 /usr/bin/x2gosqlitewrapper 4.) DATABASE SETUP (SQLite only) -------------------------------- $ x2godbadmin --createdb 5.) INIT SCRIPT --------------- Create a simple init script that starts $PREFIX/sbin/x2gocleansessions on system start (runlevel 2-3-4-5). Alternatively, you can add a single line to /etc/rc.local: /usr/local/sbin/x2gocleansessions & ============= END QUOTE ================ Here, there's some debianism, these two commands, addgroup and adduser, must be some debian specific wrappers for groupadd and useradd. Can you please give me the regular groupadd and useradd command equivalents? Also, in some documentation files, I've see mention of a group x2gousers, while here the group name is x2gouser. Which one is it? Then there's the confusion of which packages I really need. So far I'm compiling the below packages in the following order: nxcomp nxproxy nxcompshad nxcompext x2goserver x2goclient I use git for pulling the source by the way. Then I do $ chown root:x2gouser /usr/lib/x2go/x2gosqlitewrapper $ chmod 2755 /usr/bin/x2gosqlitewrapper Then I run as roon x2godbadmin --createdb (I use sqlite) and finally x2gocleansessions Then from another computer I fire up the x2goclient, create a connection and try to initiate it. This is what I get in the console: $ x2goclient ONMainWindow constructor Can't load translator (:/x2goclient_en_us) ! Can't load translator :/qt_en_US ONMainWindows constructor finished, home Directory is: "/home/ivan" read 2 sessions from config file start new ssh connection setting SSH DIR to "/home/ivan/ssh" ssh connection ok continue normal x2go session "x2gostartagent 1024x768 adsl 16m-jpeg-9 unix-kde-depth_24 us pc105/us 0 D KDE" Agent output: "50 4e95e90f6adaf1f7288f53a489a4e605 2449 ivan-50-1312372325_stDKDE_dp24 30004 30005 30006 " starting nxproxy with: "nxproxy -S nx/nx,options=/home/ivan/.x2go/S- ivan-50-1312372325_stDKDE_dp24/options:50" " NXPROXY - Version 3.4.0 Copyright (C) 2001, 2010 NoMachine.

If I try to login again, I get a window listing one running session, which I can't resume and an error message: Connection failed channel_open_session failed - Received SSH_MSG_DISCONNECT: Received ieof for nonexistent channel 0. In the debian installtion, I see you use sudo but in the INSTALL file this step is missing. I've install sshfs anf fuse and I believe all the other dependencies. My questions are: 1) Any way to enable debugging on the server side 2) Any way to enable debugging on the client side 3) Do I need to install and use x2goagent Any help/hints/useful links you offer will be greatly appreciated. When I get everything working, I will contribute a nice write-up for use on the wiki. Modesty aside, I believe I write pretty clear and good documentation. As I'm working on my own LFS-based distribution, I will be following the new releases of x2go and will be updating the instructions too. Thanks, IvanK.
