translating X2Go
by Mike Gabriel 19 Feb '12

19 Feb '12

Hi all, over the weekend Daniel Lindgren and Terje Andersen have added Swedish and Norwegian translations to X2Go Client and Pyhoca-GUI. We have set up a wiki page together that explains how translating X2Go works: http://wiki.x2go.org/wiki:development:i18n The translators communicate on: x2go-i18n(a)lists.berlios.de We currently need help with any language apart from: German Bokmal (Norway) Swedish The following language we have translators for, but the teams could grow here: Dutch Russian Spanish (currently only for PyHoca-GUI) Apart from the named language no other languages are supported within X2Go components. If you are shy with coding but speak a language that is not on the list here (or that is on the bottom list), then do not hesitate to support the i18n team of X2Go. Join the list... http://lists.berlios.de/mailman/listinfo/x2go-i18n ... and start translating X2Go into your regional language!!! Welcome everyone!

Problem with X2Go and VMWare Tools
by Daniel Lindgren 18 Feb '12

18 Feb '12

Hi. I've been troubleshooting a weird problem with X2Go for a while, when connecting to Gnome sessions in virtual machines the top and bottom panels are displayed but the desktop/background never shows up and the mouse pointer never stops spinning. It's like the Gnome session startup reaches 99% and then just waits forever for something. It turns out it's related to VMWare Tools. I use VMWare Hypervisor (ESXi) 5, I can't say if the problem started when I upgraded from ESXi 4 to 5, but it's fairly recent. I discovered that there are two instances of vmtoolsd running, the process list looks something like this when the X2Go session reaches "wait forever" state: root@labblinux:~# ps auxw | grep vmware dali 12906 1.4 1.4 174604 14588 ? S 18:47 0:00 /usr/lib/vmware-tools/sbin64/vmtoolsd -n vmusr dali 12956 1.4 0.3 174604 3680 ? S 18:47 0:00 /usr/lib/vmware-tools/sbin64/vmtoolsd -n vmusr root 12971 0.0 0.0 7556 860 pts/0 S+ 18:47 0:00 grep vmware If I "kill -1 12906" the other vmtoolsd (12956) dies(!): root@labblinux:~# kill -1 12906 root@labblinux:~# ps auxw | grep vmware dali 12906 0.4 1.4 174604 14616 ? S 18:47 0:00 /usr/lib/vmware-tools/sbin64/vmtoolsd -n vmusr root 13041 0.0 0.0 7556 860 pts/0 S+ 18:48 0:00 grep vmware Simultaneously the X2Go/Gnome session startup successfully finishes. Starting a Gnome session locally on the virtual machine console successfully finishes. I've tried using xrdp instead of X2Go and had no problems starting sessions, both using X11rdp and X11vnc on the server side. There's only one vmtoolsd running unless it's a X2Go session. I've unsuccessfully tried to figure out what the root cause is. It seems related to X2Go login/startup, somehow vmtoolsd starts twice and there's a conflict blocking Gnome startup. I did however find a workaround; uninstall VMWare Tools and install the open-vm-tools package from the Debian repository (contrib has to be added). No problems with X2Go so far and VMWare seems happy with the open source tools (Shutdown/Restart Guest is available in vSphere Client). I posted this to both x2go-user and x2go-dev for informational purposes. Maybe a wiki page would be the best place for this info? The wiki is however in a sad state and needs some serious cleanup. I personally don't think the template used is aesthetically pleasing and would prefer the default template or Arctic template which I've used extensively in all my DokuWiki installs. Cheers, Daniel

x2goagent listening on public interface - how to make it listen on 127.0.0.1 only?
by BUGHUNTER 18 Feb '12

18 Feb '12

Hi, I am testing x2go - looks like a very good alterative to other solutions! However, I see that (only) when I am logged in via x2goclient I have an x2goagent process listening on all network interfaces on port 6050 - I would feel better if this software did only listen on 127.0.0.1, if this is technically possible. I did not found any hint on a "listen 127.0.0.1" configuration item and where to put it, if existing - how can I make x2goagent NOT listen on a public network interface? Thanks for your attention, Bughunter

Re: [X2go-User] updated x2go on my ubuntu 11.10 system and it now fails - workaround
by brian mullan 18 Feb '12

18 Feb '12

I haven't been able to figure out why my updated x2go is failing to allow ssh login and start of my x2go session. But I have figured out a workaround but it makes the question of what the real problem is even stranger ? *The workaround was to setup SSH Login Without Password Using ssh-keygen & ssh-copy-id* For those that haven't done it before an easy/simple explanation of what you have to do is found here: http://www.thegeekstuff.com/2008/11/3-steps-to-perform-ssh-login-without-pa… for Ubuntu the instructions are here: https://help.ubuntu.com/community/SSH/OpenSSH/Keys After doing this from your "client" system start the x2goclient and: 1. create a new session 2. select "*session preferences*" from the drop-down menu on your "new session" launcher icon 3. check mark "*Try auto login (ssh-agent or default ssh key)*" option 4. enter your Host address/dns name 5. enter your login name 6. click OK to save 7. Click on the session Launcher ICON and now it should just autoconnect to your remote server with ssh and start your x2go session successfully Now as to why the new x2goclient was failing and giving that message before when the only difference is whether or not auto-login was used or x2go's ssh key exchange ... I don't know. The only thing I can think of is that there was some kind of "key" mismatch between the server and the client before *which when I setup auto-login would have been bypassed because the auto-login setup transfers a new RSA key to make sure they match between machines. * Anyway setting up auto-login now lets x2goclient start the session successfully !! <g> Brian ---------- Forwarded message ---------- From: Paul van der Vlis <paul(a)vandervlis.nl> To: brian mullan <bmullan.mail(a)gmail.com> Cc: x2go-user(a)lists.berlios.de Date: Fri, 17 Feb 2012 14:37:26 +0100 Subject: Re: [X2go-User] updated x2go on my ubuntu 11.10 system and it now fails Op 17-02-12 13:51, brian mullan schreef: > Mike > > PyHoca was also updated and now it won't load and gives me a message: > > /*pyhoca-gui[9111] (PyHoca-GUI) WARN: the current release of PyHoca-GUI > does not support client configuration* > / > It did work before I updated this week. > > To update I used the Ubuntu repository info from the x2go-wiki: > > http://wiki.x2go.org/wiki:x2go-repository-ubuntu > > $ sudo add-apt-repository ppa:x2go/stable > $ sudo apt-get update > > The x2goclient version is *3.99.0.6-0-144-oneiric* > > As I'd mentioned my laptop hasn't been updated and it still connects > fine with both x2goclient & pyhoca to the same server AND > on my desktop which was updated I CAN successfully connect to the server > using just SSH. > > I tried to find some troubleshooting guide on the wiki that would at > least point to where log files might be but couldn't find anything. > If there are some troubleshooting steps posted somewhere for x2go I'll > use them to see if I can figure out what's going on. > > thanks.

I have tried much to get rit of this problem, but with no success. Interesting is that I can use pyhoca-gui without problems where X2goclient failes. But the last time I've tried this I had a problem with Pyhoca-gui: the keyboard did not work fine over the session. It did work, but often there where key-presses missing. Over another direct SSH connection typing was no problem.

updated x2go on my ubuntu 11.10 system and it now fails
by brian mullan 17 Feb '12

17 Feb '12

Had an older version of x2go working. Updated x2go client on my home PC Using Ubuntu 11.10 64bit for x2goserver Installed x2goserver as usual >From my client (also Ubuntu 11.10 64 bit)... I try to connect and get the message about accepting a server connection not seen before and I answer - yes. I then get the x2goclient window to provide my password and I do so. It comes back immediately with this message? *Access denied. Authentication that can continue: publickey,keyboard-interactive* I've not seen that before but anyone got an idea what's causing it? sshd_config on the server is configured to allow password logins AND if I use SSH I can connect from my local machine to the remote server OK. So its not an SSH problem. I then tried my work laptop which still has the older version of x2go and it DOES connect ok. Something is broken now on my home PC. I purged the x2goclient from my home machine just in case but I still have the same problem. If anyone has any suggestions as to how to troubleshoot or a log to look at I'd appreciate any tips. thanks brian

Shared desktop
by segalion 16 Feb '12

16 Feb '12

I have sucessfully install x2go on ubuntu 11.10, and x2goclient on windows... I have sucessfully connect with "custom" and gnome-session-fallback I have succesfully connect with "desktop shared" and fullcontrol and I have the following problems... 1. Mouse dont apear. This is the most anoying 2. Other resolution diferent than fullscreen fails. 3. suspend and terminate button dont works Please can anybody helpme mainly with mouse problem? Thanks... What is the tecnicallity used for desktop sharing? RFB-VNC?. I cant see any x11vnc session as freenx do... NOTE. x2goclient doesnt support http proxy connections so I had to make a sshtunnel with putty, and then a x2go session inside (with 2 level of tunnelling ), Could be great to have proxy connection support as nomachine client.... Thanks a lot for this great project.

X2Go client windows switching problems
by Mike 16 Feb '12

16 Feb '12

Hello all, Long time user of NX related programs for some time now. Mostly freenx, which has been driving me crazy lately. I am a staunch Debian user and feel that it's unlikely that freenx will ever enter main there. Hence my want to switch to X2Go. I've been following and trying to get this working for me too long now. The largest hurdle that is stopping me now is the inability to switch windows properly when using the windows X2Go client. I keep a long running session open on a remote box and prefer to keep most of my work there. The problem is that I also have a need to switch back to my local desktop often. Typically I do this with the "magic" pixel or Alt + Tab. I'm also perhaps quirky in that I want my remote session to be full screen not windowed. I do not experience this problem from a Linux laptop with X2Go or PyHoca-Gui. I can switch windows, suspend, resume, et. al. just dandy! My problem is with the M$ side of course. Starting the session is fine, even resuming one started elsewhere. When I switch back to another program though I can't get back to my session properly. Either I will see part of my desktop (KDE if it matters) and the last program I was using in windows will be covering the rest. Sometimes if I minimize that program I will get my remote session back, not often though. Typically what happens is I will get a small rectangle toward the upper left of my windows desktop. It may or may not have the minimize, restore, close widget displayed with it. When this happens the only way back to my remote session is to close the client and reconnect. This does work, far too painful to deal with. Seems that I have just been babbling here. If I can describe it some other way, post logs, config, whatever I am willing to do that. A quick kick in the right direction would be appreciated. Server logs show nothing at any debug level that I see. Any help is greatly appreciated. Mike

Sound issues in new release
by Frank Schlingmann 14 Feb '12

14 Feb '12

Dear all, I hope this is the right place for my problem as I have started with x2go only e few weeks ago and could not find many resources. I did a test two weeks ago and sound was working well. Now I made a new installation and encountered two problems compared to my last installation: - when I login remotely there is now start-sound - when I use flash (e.g. browser) I can only hear sound in the left speaker. My client is a WinXP and the server is running ubuntu 11.10 in a virtual box. In my first test (two weeks ago) I heard the start-sound when I logged in remotely. I am not quite sure about stereo but I think both channels worked also. Now I made a fresh install of x2go on the server today and faced the problems mentioned above. I made an upgrade on the client from 3.99.0.3 to 3.99.0.4 with no changes, the problems persist. Did I miss something? Any help is appreciated. Frank

Problem Using Cloned Accounts
by senrabdet＠aol.com 08 Feb '12

08 Feb '12

Hi All: We're trying to see if we can get x2go to work on cloned accounts or ones we create via bash on an Ubuntu server. FYI - we can start x2go sessions successfully if we create a new user "the normal way" (i.e., by hand using the GUI), create the SSH keys and move them between client (windows) and server. When we try, however, to create a new user account on the server "programmatically" (either brand new or cloned), we consistently get an error which happens regardless of the technique we use. As best we can tell, the cloned or programmatically created accounts function fine and as we'd expect except when we try to connect via x2go. For example, as root we create an account with "useradd - d /home/<newusername> -m --skel /etc/skel <newusername> (we've also tried to use the same command but clone an account that works with x2go, and have tried a range of other bash "create/clone" code). The connection is made, we see the black screen with "X2GO" and then the screen goes black and stays that way. Is this the same problem we've seen on some of the "black screen" posts? When we quit, we get an error message: Connection failed head: cannot open /home/<username>/.x2go/C-XXXXXXXXXXX_stDGNOME-dp32/cmdoutput' for reading: No such file or directory sed: -e expression #1, char 4: unterminated 's' command cat: >From reading the error message, it looks like somehow a "cmdoutput" file or folder is missing which we don't fine on the working account, so maybe it's written out on the fly. Is this a permissions issue? We think we are doing everything "identically" with the exception of how we are creating the account (e.g., how we create the ssh keys, copy the id_dsa.pub in authorized keys, add the new user to sshd_config, restart ssh). We've tried comparing the permissions in the two accounts, but are not sure if that is even the issue. We've checked in our user settings via the GUI and none of the users we've added --either programmatically or through the GUI--are checked in the x2go group though all are listed there and it doesn't seem to matter if we check them. When we create a new user/account "programmatically", would this cause problems with the x2go set up for that account? Any help appreciated! Ted
