Folder sharing does not work with x2goclient
by Emanuele Rocca 27 Nov '14

27 Nov '14

Hi list, While folder sharing works fine using pyhoca-cli, it does not work at all with x2goclient. This is what sshd says on the client side when trying to "share" a folder from the gui: May 8 13:55:43 uranus sshd[23908]: Connection from 127.0.0.1 port 51821 May 8 13:55:43 uranus sshd[23908]: Connection closed by 127.0.0.1 [preauth] mount's output on the server side does not show anything interesting. I am running Ubuntu precise (12.04), both on the client and the server. Do you have any hints on how to debug this further? Installed packages: ii cups-x2go 3.0.0.3-0~54~oneiric1 X2GO printer for CUPS ii python-x2go 0.1.1.9-0-0~612~oneiric1 Python module for X2go client support ii x2goagent 2:3.5.0.11-0~220~oneiric1 X2Go agent ii x2goclient 3.99.0.6-0~144~oneiric1 X2Go Client application (Qt4) ii x2gognomebindings 2.0.1.4-0~53~oneiric1 Description: x2gognomebindings (GNOME mimetypes for X2go) ii x2goserver 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts ii x2goserver-compat 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (backwards compatitbity to old client versions) ii x2goserver-extensions 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (extensions) ii x2goserver-fmbindings 3.1.0.0-0~477~oneiric1 Generic (freedesktop-based) file manager bindings for X2Go ii x2goserver-printing 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (printing) ii x2goserver-pyhoca 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (add-ons for pyhoca client) ii x2goserver-xsession 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (Xsession runner) ii pyhoca-cli 0.1.4.2-0~108~oneiric1 A command line X2go client written in Python ii pyhoca-gui 0.1.0.10-0~487~oneiric1 A graphical X2go client written in (wx)Python ii x2goserver-pyhoca 3.1.0.0-0~477~oneiric1 X2Go server daemon scripts (add-ons for pyhoca client) Conf file: [20120503160857309] speed=3 pack=16m-jpeg quality=9 fstunnel=true export="/media:1;" iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=false width=1024 multidisp=false display=1 height=768 dpi=96 setdpi=false xinerama=false usekbd=true layout=us type=pc105/us sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=xxx icon=:icons/128x128/x2gosession.png host=host.example.org user=username key= sshport=22 autologin=false krblogin=false rootless=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL, gnome-session-fallback command=gnome-session-fallback rdpoptions= rdpserver= xdmcpserver=localhost

Mac OSX and keyboard
by Paul van der Vlis 02 Sep '14

02 Sep '14

Hello, Is X2goclient working on Mac OSX? I read some messages that there are keyboard problems. Not sure they are gone. Here is such a message, with a link to another message: http://www.mail-archive.com/x2go-user@lists.berlios.de/msg00632.html When the problem is fixed, is this also the case for the Lenny version of X2go? (I have a customer with Macs who does not want to upgrade because the office will be closed in a few months.) With regards, Paul van der Vlis. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl

Xwin start failure: unsafe environment error
by Gertjan Hofman 13 Aug '13

13 Aug '13

Hello, I am running 3.99.2.1 on Win-7 64 bit, accessing a Linux desktop locally. Worked fine for a while although I some time got an error which is not persistent: when connecting to the session I get: Xserver aborted due to an unsafe environment. Win was started with the following command line: (null). A quick google of the error brings me to the parsing the args of the x-server. Is the x-server being started with a wrong command line ? Is this an x2go issue or xwin ? If any one can tell me how to collect more info, much appreciated. Thanks Gertjan

Re: [X2go-User] Mac client 'Can't connect to X-Server
by Neil Hunt 14 Nov '12

14 Nov '12

Paul, Unfortunately as a regular user of the Mac X2go client, this is something I've seen many times. Unfortunately, I haven't found any fix for it. The good news is that it rarely happens if you keep the X11 application open. Always open X11 before starting your X2go session. From there, you can stop/start X2go sessions, even the X2go client itself, however I almost always keep my X11 app running even when it's not being uses and then I don't get the problem you are describing. If I quit X11, especially if it's accidental during an active X2go session, then I end up with the problem you are describing and the only option is to restart the whole computer. But if I keep it open, I go for days or weeks without rebooting. Ultimately, I think we should look to move to the PyHoca gui, but we haven't been able to find any serious python developers to port it to OS X. Neil -------------------------------------------------------------------------------------------- Date: Wed, 6 Jul 2011 12:14:51 -0700 From: Paul Northug <pnorthug(a)gmail.com> To: x2go-user(a)lists.berlios.de Subject: [X2go-User] Mac client 'Can't connect to X-Server' Message-ID: <CAJAeRZy=KmQsVyoELQ4MrTDHZ8g03x8tXJm_hTL5NK50jQ9QEw(a)mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Thank you to the developers for make this excellent software. Many people at my work use x2go's Mac client. We have never been able to figure out how to resolve the 'Can't connect to X-Server' error without random acts (eg. rebooting). We are not sure why it comes up. This is what I do: 1. Start X11.app 2. ssh -X remotehost 3. xterm & So far this works, I get an xterm so there is nothing wrong with X11 4. Start X2Go client 5. Start a session (port 22, dsa authentication, Gnome...) 6. Client gives the error and hangs (Abort and Terminate don't do anything) and I have to close the application. The closest we got to figuring it out is that the X11.app possibly changes it's DISPLAY on restarts and perhaps the x2go client is expecting display 0. Is there any more debugging information that I could get from the client to see what exactly it is doing prior to giving the error message? We have tried some of the suggestions in the forums, such as changing permissions in X11.app (this is necessary), starting it manually before starting the client. We have also done things like messed with firewall settings, made sure hostname doesn't change on our laptops between work and home, deleted preference files, delete XAuthority files, etc. What seems to work is rebooting. Thanks, P?l

Are logcheck rules for x2goserver available somewhere?
by Holger Krause 05 Nov '12

05 Nov '12

Dear list, logcheck includes many lines related to x2go programs in it's reports. Some examples are: Oct 29 10:15:38 remote /usr/bin/x2goterminate-session: session with ID XXX has been terminated successfully Oct 29 10:15:46 remote /usr/bin/x2gostartagent: successfully started X2Go agent session with ID XXX Oct 29 10:16:00 remote /usr/bin/x2gomountdirs[23127]: WARNING: mounting of /cygdrive/C/Users/___/spool failed Oct 29 10:19:04 remote /usr/bin/x2goresume-session: client <IP> has successfully resumed session with ID XXX Oct 29 10:19:13 remote /usr/bin/x2gomountdirs[9728]: WARNING: mounting of /cygdrive/C/___/spool failed Oct 29 10:19:32 remote /usr/bin/x2gosuspend-session: session with ID XXX has been suspended successfully Most of these messages indicate normal operation and shouldn't be reported by logcheck. This is usually achieved by adding a file containing a set of rules corresponding to messages generated by the server during normal operation in /etc/logcheck/ignore.d.* directories. Is such a set of rules available somewhere? Thanks in advance, Holger

Why doesn't the X2Go Client have XFCE? Isn't there a way to set up XFCE? Why doesn't PyHoca work? I launch a remote host, it asks for signon and that is approved, but then nothing. Manual launch, and nothing. Debian Testing with X2Go 3.99.3.0-0 -- http://www.fastmail.fm - Send your email first class

zombie processes
by richard lucassen 28 Oct '12

28 Oct '12

Hello list, I'm newbie to x2go and tonight I installed x2goserver on a "Debian Testing" server. Everything works ok, but I see <defunct> zombie processes when starting x2goserver: 3748 pts/1 S 0:00 /usr/bin/perl /usr/sbin/x2gocleansessions 3752 pts/1 S 0:00 \_ sh -c /usr/lib/x2go/x2golistsessions_sql myhost1 2>/dev/null 3753 pts/1 S 0:00 \_ /usr/bin/perl /usr/lib/x2go/x2golistsessions_sql myhost1 3760 pts/1 R 0:00 \_ /usr/bin/perl /usr/lib/x2go/x2gosqlitewrapper.pl listsessionsroot myhost1 I edited it just a bit because of line wrapping. After a few seconds three zombie processes remain: 3748 pts/1 S 0:00 /usr/bin/perl /usr/sbin/x2gocleansessions 3752 pts/1 Z 0:00 \_ [sh] <defunct> 3814 pts/1 Z 0:00 \_ [sh] <defunct> 3825 pts/1 Z 0:00 \_ [sh] <defunct> Is this a bug or am I missing something crucial somewhere. I do not run gdm or something like that on that machine. I also noticed that without starting the init script "x2goserver", I can start sessions from a client. Is that normal behaviour?

session resuming after disconnect/reconnect
by richter＠ecos.de 24 Oct '12

24 Oct '12

Hi, when a session gets disconnected (e.g. network connection is lost, computer is powered down, without disconnect) I cannot simply resume the session after the next connect. I have first to pause the session, that wait a long time (don't know exactly how long, but needs to be more than 30-60 seconds) and than I am able to resume the session. If I simply pause/resume the session or try to take it over, the operation fails and the session is closed. Looks like after the pause of the old session, something does not get terminated correctly and needs to timeout before I can resume the session. Simply pausing/resuming a session works without problems, as long as the ssh session isn't closed in between. It also works if I pause the session, than disconnect the ssh connection. Than I can resume after I have reconnected to the server. Regards Gerald

ssh parameter?
by richter＠ecos.de 24 Oct '12

24 Oct '12

Hi, I am using PyHoca on Windows. Sometimes pyhoca disconnects from a server (while for example putty keeps connected to the same server). I guess there is some time out or keep alive that is too low, so the session gets disconnected, when the connection is unreliable. This there some way to configure the ssh parameters (e.g. configfile)? Also for some host the ssh host key has been saved and for others every time I connect I have to answer yes to accept the host key. Is there any way to tell pyhoc to save the host key? Thanks & Regards Gerald
