Problem with Autologin through SSH Tunnel
by Mathias Ewald 24 Mar '14

24 Mar '14

Hi, I am seeing a problems with a new set up environment using the broker with SSH tunneling and session autologin. I start x2goclient connecting to my broker, log in, receive a list of session profiles, select the one that uses auto login, enter my SSH proxy password and get asked to enter a password for some key. Authentication to the broker is no problem: -- 2014-03-24 13:49:12,972 - broker - INFO - X2Go Session Broker (0.0.3.0), 2014-03-24 13:49:12,973 - broker - INFO - written by Mike Gabriel (X2Go Project) <mike.gabriel(a)das-netzwerkteam.de> 2014-03-24 13:49:12,973 - broker - INFO - Setting up the broker's environment... 2014-03-24 13:49:12,974 - broker - INFO - X2GOBROKER_DEBUG: True 2014-03-24 13:49:12,974 - broker - INFO - X2GOBROKER_CONFIG: /etc/x2go/x2gobroker.conf 2014-03-24 13:49:12,974 - broker - INFO - X2GOBROKER_AGENT_CMD: /usr/lib/x2go/x2gobroker-agent 2014-03-24 13:49:12,974 - broker - INFO - X2GOBROKER_AUTHSERVICE_SOCKET: /run/x2gobroker/x2gobroker-authservice.socket 2014-03-24 13:49:12,975 - broker - INFO - X2GOBROKER_DEFAULT_BACKEND: inifile 2014-03-24 13:49:12,975 - broker - INFO - X2GOBROKER_SSL_CERTFILE: 2014-03-24 13:49:12,975 - broker - INFO - X2GOBROKER_SSL_KEYFILE: 2014-03-24 13:49:12,981 - broker - INFO - client address is 127.0.0.1 2014-03-24 13:49:12,981 - broker - DEBUG - username: mathias, password: XXXXX, task: selectsession, profile_id: termsrv, cookie: 2014-03-24 13:49:12,982 - broker - DEBUG - base_broker.X2GoBroker.get_authentication_mechanism(): found default-auth-mech in global config section: pam 2014-03-24 13:49:12,982 - broker - DEBUG - base_broker.X2GoBroker._do_authenticate(): authenticating user=mathias with password=<hidden> against backend=inifile. 2014-03-24 13:49:12,982 - broker - DEBUG - connecting to authentication service socket /run/x2gobroker/x2gobroker-authservice.socket 2014-03-24 13:49:12,983 - broker - DEBUG - sending username=mathias, password=<hidden>, service=x2gobroker to authentication service 2014-03-24 13:49:12,999 - broker - INFO - authentication against PAM service »x2gobroker« succeeded for user »mathias« 2014-03-24 13:49:12,999 - broker - DEBUG - base_broker.X2GoBroker.check_access(): result of authentication check is: True 2014-03-24 13:49:13,006 - broker - DEBUG - base_broker.X2GoBroker.get_agent_query_mode(): found default-agent-query-mode in global config section: none -- After entering the SSH Proxy password auth.log says -- Mar 24 13:52:43 access sshd[24551]: Accepted password for x2gosshproxy from 80.187.108.145 port 8948 ssh2 Mar 24 13:52:43 access sshd[24551]: pam_unix(sshd:session): session opened for user x2gosshproxy by (uid=0) -- so that worked, too!

I think this is where the problem lies. I assume at this point x2gobroker should connect to x2goserver using the x2gobroker account and the installed public key. Manually, I can create this connection from the broker though: -- root@access:~# su - x2gobroker x2gobroker@access:~$ ssh 10.173.20.2 Welcome to Ubuntu 13.10 (GNU/Linux 3.11.0-12-generic x86_64) * Documentation: https://help.ubuntu.com/ Last login: Mon Mar 24 17:17:29 2014 from 10.173.20.3 x2gobroker@termsrv:~$ -- Anybody with good troubleshooting skills? :D cheers Mathias

RHEL 7 beta
by Les Mikesell 20 Mar '14

20 Mar '14

Are there any tricks to getting an x2go session to work with the x2goserver package from EPEL for the RHEL 7 beta distribution? My first attempts asking for a gnome session from a windows client connect, open a window, but then display an 'Oh no! Something has gone wrong' error message instead of drawing the desktop. Is this because everything is beta and not quite working yet or am I doing something wrong? -- Les Mikesell lesmikesell(a)gmail.com

what is "bernd.lentes@127.0.0.1:/cygdrive/D/DOCUME~1/BERNDL~1.000/X2GO~1/S-67AA~1/spool on /tmp/.x2go-root/spool/C-root-52-1395158341_stDKDE_dp32 type fuse.sshfs" ?

Hi, when i connect using X2go from a windows host to a linux host, on the linux host the following mountpoint appears: bernd.lentes@127.0.0.1:/cygdrive/D/DOCUME~1/BERNDL~1.000/X2GO~1/S-67AA~1/spool on /tmp/.x2go-root/spool/C-root-52-1395158341_stDKDE_dp32 type fuse.sshfs (rw,nosuid,nodev,default_permissions) Can anyone explain me why x2go uses a mountpoint to connect to a remote host ? Another mystery for me is why can't i access the folder /tmp/.x2go-root/spool/C-root-52-1395158341_stDKDE_dp32. And i don't find the folder /tmp/.x2go-root/spool/C-root-52-1395158341_stDKDE_dp32 on my windows systems. Using df on the linux host hangs without giving results. Terminating the connection df runs fine. Can anyone put a bit light on it for me ? Thanks in advance.

having problems in installing X2Go Server on SLES 11 SP3
by Lentes, Bernd 18 Mar '14

18 Mar '14

Hi, i'd like to install X2Go on a SLES 11 SP3 host, 64bit. I have installed the rpm for the server sucessfully, it has been version 4.0.1.8-2.5. There was a dependency which i resolved: Installing: perl-DBD-SQLite-1.40-30.1 [done]. When i try to connect from the Windows client, i get this error: http://www.directupload.net/file/d/3565/zdwseya3_jpg.htm Following https://bugs.mageia.org/show_bug.cgi?id=6729 , i did "x2godbadmin --createdb". The next error appeared: install_driver(SQLite) failed: "Unable to get DBI state function. DBI not loaded. at /usr/lib/perl5/5.10.0/x86_64-linux-thread-multi/DynaLoader.pm line 226. Compilation failed in require at (eval 6) line 3. at /usr/sbin/x2godbadmin line 92" Can anyone help me in installing the X2go Server ? Until now, i've been very happy in using X2go, the connections are more stable than the ones from nomachine origin. Thanks in advance.

Multi display - only for thin clients?
by Tobias Luther | X2Go-Community.org 17 Mar '14

17 Mar '14

Hello everybody, there is the question how to use multi display for X2Go. The client does have the Xinerama option, but reading the wiki http://wiki.x2go.org/doku.php/doc:usage:multi-display I understand this is for thin clients only? Also, man x2goclient does not mention this at all. I have got only one monitor at my setup, therefore I am not able to test this myself. Thanks a lot, tobias

x2go vs synergy vs NX vs vnc, etc. (keyboard grab)
by Les Mikesell 17 Mar '14

17 Mar '14

I run synergy (http://synergy-foss.org/) to share my desktop keyboard/mouse with a laptop sitting to the side, and run an assortment of remote-access tools (x2go, NX, vmware client, vnc, etc.) that also grab the mouse/keyboard/clipboard. Sometimes it seems like x2go is conflicting with synergy but it is not very consistent - and sometimes anything that keeps the network very busy will make synergy unresponsive. Is there any way to tell what is really going on? -- Les Mikesell lesmikesell(a)gmail.com

Win32 X2Go Client: Please Test nightly 4.0.2.0 build with PulseAudio 5.0
by Michael DePaulo 16 Mar '14

16 Mar '14

http://code.x2go.org/releases/binary-win32/x2goclient/heuler/mingw32-4.4/qt… Notes: 1. I am not submitting the attached patch for inclusion via this mailing list. I already have commit/push access. I will commit & push it once it is tested enough. It will be the commit for bug 422. 2. "--console" is enabled for x2goclient.exe, that's why you see a terminal open up when you launch X2Go Client. When 4.0.2.0 is released, this will be disabled. 3. If 4.0.2.0 were to be released tomorrow with this patch, the installer will be more like 24.8 MB, not 30.7 MB. This installer is larger because I included the pulseaudio source code, and because I included lots of unneeded pulseaudio modules (.DLL files.) 4. For more info about the PulseAudio 5.0 bulid (OBS rev18): http://comments.gmane.org/gmane.comp.audio.pulseaudio.general/19865

Buggy File & Folder sharing
by Thierry Kauffmann 14 Mar '14

14 Mar '14

Hi, File & Folder sharing seems to be buggy : I works well for me, using x2go client 3.99.0.5 on ubuntu 12.04 64bits. x2gomountdirs succeeds in mounting local folders. It uses sshfs adresses in the form local_client_user_name@127.0.0.1:server_port/local_path Nevertheless, I doesn't work with a Xubuntu 12.04 32bits client neither with a MAC OS X client : x2gomountdirs tries to mount adresses in the form local_path/ - ie not using ssh port forwarding -. It can not succeed since local_path does not exist on the server ! Problem seems to be linked only to client OS configuration : users have well been added to the fuse group on server. Any ideas (client ssh configuration, ...) ? Best regards, Thierry PS : server is a Xubuntu 64bits running x2goserver 4.0.1.13 -- <http://www.fdsweb.univ-montp2.fr> Thierry KAUFFMANN Chef du service informatique (SIF) Tél : +33 4 67 14 31 58 <tel:+33%204%2067%2014%2031%2058> Mail : Thierry.Kauffmann(a)univ-montp2.fr <mailto:Thierry.Kauffmann@univ-montp2.fr> CC 437 - Place Eugène Bataillon. 34095 Montpellier Cedex 5 - FRANCE. www.fdsweb.univ-montp2.fr <http://www.fdsweb.univ-montp2.fr> FACULTÉ DES SCIENCES/ UNIVERSITÉ MONTPELLIER 2

Does anyone on the x2go team watch/listen to the floss weekly podcast? http://twit.tv/show/floss-weekly/feed I think x2go would make a great topic if anyone wants to talk about it. Directions for getting a project on the show are on the feed page "Email Randall...". -- Les Mikesell lesmikesell(a)gmail.com

Resolution Problem openSuSE 13.1 vs 12.3 & Debian 7.4.0
by Tobias Hadem 13 Mar '14

13 Mar '14

Hi everybody, i am testing openSuSE 13.1 right now and i have a problem with the automatic setting of a full-screen-resolution. It works without any problem on a Debian 7.4.0 and a openSuSE 12.3, on 13.1 the vertical resolution of 1920 is correct but horizontal resolution is around 1200 instead of 1080. The taskbar on the bottom and the top pixels are outside the screen and the mouse can't reach it. The auto-mounter-pop-up can be half seen, so it looks like 1920x1200 is set. The client is always a windows-x2go-client with exactly the same config, the only difference is a changed ip-address as server so i can test in parallel. Anybody had that problem before? Below is a version-comparison in case that helps. I would love to supply logfiles, i just can't find anything remarkable in syslog and session-log, so i need a hand with that (activate debug, etc) openSuSE 12.3: x2goagent:3.5.0.21 x2goserver:4.0.1.6 xorg-x11:7.6_1-7.1.1 openSuSE 13.1: x2goagent:3.5.0.21 x2goserver:4.0.1.6 xorg-x11:7.6_1-11.3.1 Debian 7.4.0: x2goagent:3.5.0.22 x2goserver:4.0.1.13 x11-common:7.7+3~deb7u1 Thanks a lot!
