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

X2Go client 4.0.0 can't resume certain sessions
by Sebastian Flothow 11 Nov '13

11 Nov '13

Hi, we've encountered an issue where (at least) X2Go client 4.0.0.3 on Windows can't resume certain sessions. If this has been discussed before please point me to the relevant threads/bugs; I didn't find anything. The behavior is as follows: The affected version of the client is able to start new sessions, and also resume suspended sessions; however, resuming sessions after some delay (a few hours) causes the client to hang. Other versions of the client are then still able to resume this session, but even when resuming and suspending the session with a working client version, attempting to resume the session immediately afterwards in an affected client causes it to freeze. I've tried the following versions so far: 3.99.2.1 on Linux: works 3.99.2.2 on Windows: works (n.b. filename is x2goclient-3.99.2.1-setup.exe) 4.0.0.3 on Windows: affected 4.0.1.1 on Linux: works Server side versions are: x2goagent: 3.5.0.21 x2goserver: 4.0.1.6 x2goserver-xsession: 4.0.1.6 Can anybody confirm that this is something which has been fixed in client 4.0.1? If so, when is there going to be a 4.0.1 client for Windows? (In the meantime, we're downgrading our Windows users to 3.99.) - Sebastian

Re: [X2Go-User] X2Go-User Non-Digest, Vol 38, Issue 26
by Ted Barnes 31 Oct '13

Hi Mike: How are you? Another update...hope am making progress, but not there yet. Let me know if it would help to send over copies of x2gobroker.conf and the other configs? Is it the case I am using the wrong backend, and don't know how to set it to backend inifile? Thanks for the help(!) 1) Rebuilt server (using Squeeze) and incorporated nightly x2go builds apt-get install -y x2goserver x2goserver-xsession apt-get install -y x2gobroker-wsgi apt-get install -y apache2 (apache fails until instill libapache2-mod-wsgi) apt-get install -y libapache2-mod-wsgi apt-get install -y x2gobroker-authservice 2) Checked versions x2gobroker-wsgi: 0.0.3.0-0~x2go1+squeeze~heuler~20131002~558~build1 x2goserver: 4.1.0.0-0~x2go1+squeeze~heuler~20130731~779~build1 x2gobroker-authservice: 0.0.3.0-0~x2go1+squeeze~heuler~20131002~558~build1 3) Set backend to inifile In x2gobroker.conf: [inifile] enable = false session-profiles = /etc/x2go/broker/x2gobroker-sessionprofiles.conf * have made various tweaks to x2gobroker-sessionprofiles.conf, x2gobroker.conf, and x2gobroker-wsgi.apache.conf - have not touched x2gobroker-wsgi.apache.vhost without noticeable difference in outcome. 4) When try to connect: Not sure this matters, but on client get: x2go-INFO-1> "Starting x2goclient..." x2go-WARNING-1> "Can't load translator: :/x2goclient_en_us" x2go-WARNING-2> "Can't load translator: :/qt_en_US" And... SSH - says inifile not enabled....(when try to connect first time, does ask if I want to trust key and creates known hosts file) x2goclient --broker-url="ssh://user@xxx.xxx.xxx.xxx/usr/bin/x2gobroker --backend=inifile" 2013-10-31 07:00:32,777 - broker - INFO - X2Go Session Broker (0.0.3.0), 2013-10-31 07:00:32,786 - broker - INFO - written by Mike Gabriel (X2Go Project) <mike.gabriel(a)das-netzwerkteam.de> 2013-10-31 07:00:32,789 - broker - INFO - Setting up the broker's environment... 2013-10-31 07:00:32,790 - broker - INFO - X2GOBROKER_DEBUG: True 2013-10-31 07:00:32,790 - broker - INFO - X2GOBROKER_CONFIG: /etc/x2go/x2gobroker.conf 2013-10-31 07:00:32,790 - broker - INFO - X2GOBROKER_AGENT_CMD: /usr/lib/x2go/x2gobroker-agent 2013-10-31 07:00:32,790 - broker - INFO - X2GOBROKER_AUTHSERVICE_SOCKET: /run/x2gobroker/x2gobroker-authservice.socket 2013-10-31 07:00:32,790 - broker - INFO - X2GOBROKER_DEFAULT_BACKEND: zeroconf 2013-10-31 07:00:32,790 - broker - INFO - X2GOBROKER_SSL_CERTFILE: 2013-10-31 07:00:32,791 - broker - INFO - X2GOBROKER_SSL_KEYFILE: 2013-10-31 07:00:33,039 - broker - ERROR - broker backend ,,inifile'' is disabled on this system When try HTTP, get "Error Login failed!

Hi Mike: Thanks for the help...no joy yet, but some updates (in a separate email, I'd like to circle back around on using SSL/SSH and the option of using x2goplugin with SSL as an alternative short term): 1) I mis-wrote earlier - the server I'm using is Wheezy, and the client Squeeze. Not sure that matters, but wanted to convey as such. 2) FYI, can go to server's webpage and get generic apache "It works! This is the default web page for this server. The web server software is running but no content has been added, yet.", so think apache is running. SSH is running as well on the server. 3) Again FYI have been trying x2gobroker-wsgi (not x2gobroker-daemon) 4) When I try: x2goclient --broker-url=http://xxx.xxx.xxx.xxx/plain/inifile I get an error window: Login Failed! Please try again When I try: x2goclient --broker-url="ssh://xxx.xxx.xxx.xxx/usr/bin/x2gobroker --backend=inifile" I get: sh: 1: /usr/bin/x2gobroker: not found FYI: on the server, there isn't an x2gobroker in /usr/bin....there is an x2gobroker script in /usr/sbin. If I try: x2goclient --broker-url="ssh://xxx.xxx.xxx.xxx/usr/sbin/x2gobroker --backend=inifile" I get an error window with a fair amount of info: 2013-10-29 19:01:05,325 - broker - INFO - X2Go Session Broker (0.0.2.3), written by Mike Gabriel (X2Go Project) <mike.gabriel(a)das-netzwerkteam.de> 2013-10-29 19:01:05,325 - broker - INFO - Setting up the broker's environment... 2013-10-29 19:01:05,325 - broker - INFO - X2GOBROKER_DEBUG: True 2013-10-29 19:01:05,326 - broker - INFO - X2GOBROKER_CONFIG: /etc/x2go/x2gobroker.conf 2013-10-29 19:01:05,326 - broker - INFO - X2GOBROKER_AGENT_CMD: /usr/lib/x2go/x2gobroker-agent 2013-10-29 19:01:05,326 - broker - INFO - X2GOBROKER_AUTHSERVICE_SOCKET: /run/x2gobroker/x2gobroker-authservice.socket 2013-10-29 19:01:05,326 - broker - INFO - X2GOBROKER_DEFAULT_BACKEND: zeroconf 2013-10-29 19:01:05,326 - broker - INFO - X2GOBROKER_SSL_CERTFILE: 2013-10-29 19:01:05,326 - broker - INFO - X2GOBROKER_SSL_KEYFILE: 2013-10-29 19:01:05,327 - broker - WARNING - X2Go Session Broker has been started interactively by user ted, better run as user x2gobroker. 2013-10-29 19:01:05,327 - broker - INFO - Automatically switching to DEBUG mode due to interactive launch of this application. usage: x2gobroker [-h] [-C CONFIG_FILE] [-b BIND_ADDRESS] [-d] x2gobroker: error: unrecognized arguments: --backend=inifile --user ted --task listsessions On 10/29/13 11:00, x2go-user-request(a)lists.berlios.de wrote: > Send X2Go-User mailing list submissions to > x2go-user(a)lists.berlios.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.berlios.de/mailman/listinfo/x2go-user > or, via email, send a message with subject or body 'help' to > x2go-user-request(a)lists.berlios.de > > You can reach the person managing the list at > x2go-user-owner(a)lists.berlios.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of X2Go-User digest..." > > > Today's Topics: > > 1.

x2go session broker connect problem
by Ted Barnes 29 Oct '13

29 Oct '13

Hi All: Am trying to get up to speed on x2go session broker, but am having trouble. Any suggestions? When try to connect I get: Error Login failed! Please try again. Along with... broker url: http://xxx.xxx.xxx.xxx/:8080/plain/inifilebroker url:http://xxx.xxxx.xxx.xxx/:8080/plain/inifile or.... broker url:http://user@xxx.xxx.xxx.xxx/cgi-bin/x2gobroker.cfgi As I'm getting started, I'm trying to do this on my LAN (all behind my firewall) without any ssh (longer term I want to see if I can run sessions inside SSL). I've disabled all the iptable rules on my server....and tried various settings in the x2gobroker.conf and x2gobroker-sessionprofiles.conf files which have not really changed the error message but may be the problem (see below). I can connect using the x2go client GUI "the normal way", and the first time I got a window on the client "The server is unknown. Do you trust the host key....", which I assume is x2go dynamically creating a ssh tunnel? This part works fine. However, when I try from the command line with an "x2goclient --broker-..." type of command, I get the Error message. Both client and server are running Debian Squeeze, and on the server I've successively installed: x2gobroker-wsgi apache2 libapache20mod-wsgi x2gobroker-authservice (wasn't sure if I should install this for my initial tests) My x2gobroker.conf: # This file is part of the X2Go Project - http://www.x2go.org # Copyright (C) 2011-2013 by Oleksandr Shneyder <oleksandr.shneyder(a)obviously-nice.de> # Copyright (C) 2011-2013 by Heinz-Markus Graesing <heinz-m.graesing(a)obviously-nice.de> # Copyright (C) 2012-2013 by Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> # # X2Go Session Broker is free software; you can redistribute it and/or modify # it under the terms of the GNU Affero General Public License as published by # the Free Software Foundation; either version 3 of the License, or # (at your option) any later version. # # X2Go Session Broker is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The X2Go Broker Agent has to be installed # on the local system (mode: LOCAL) or on all X2Go Servers (mode: SSH) in a # multi-server farm. # # So, there are three query modes for the X2GO Broker Agent: NONE, LOCAL and # SSH. # # NONE - Try to get along without X2Go Broker Agent queries. For simple # broker setups this may suffice. For load-balancing or reliable # session suspending and resuming the broker agent is a must!!! # # LOCAL - This LOCAL mode only works for _one_ configured multi-server farm. # If this X2Go Session Broker is supposed to serve many different # multi-server farms, then the LOCAL mode will not work!!! # # How it works: Assume that the local system has an X2Go Broker Agent # that knows about the multi-server setup. This means: X2Go Server # has to be installed locally and the X2Go Server has to be # configured to use the multi-server farm's PostgreSQL session DB # backend. # # The local system that is running the broker does not necessarily # have to be a real application server. It only has to be aware of # running/suspended sessions within the X2Go multi-server farm setup. # # A typical use-case is X2Go on top of a Debian Edu Terminal-Server # farm: # # TJENER -> PostgreSQL DB, X2Go Server, X2Go Session Broker + # Broker Agent # TS01 - TS0X -> X2Go Server configured to use the PostgreSQL DB # on TJENER # # SSH - The more generic approach, but also more complex. It allows that # the broker on this system may serve for many different X2Go Server # multi-server setups. # # With the SSH agent query mode, the X2Go Session Broker will query # one of the X2Go Servers in the targeted multi-server setup (through # SSH). The SSH authentication is done by a system user account # (normally UID=x2gobroker) and SSH pub/priv key authentication has # to be configured to make this work. # # All X2Go Servers in a multi-server farm need the X2Go Broker Agent # installed, whereas this local system running the X2Go Session # Broker does not need a local X2Go Broker Agent at all. # # The agent query mode can be configured on a per-broker-backend basis, the # below value is the default. #default-agent-query-mode=LOCAL ### ### BACKEND section ### # Possible X2Go Session Broker backends: # # 1. backend = zeroconf (activated by default) # Use the ZeroConf X2Go Session Broker backend, this backend is for demo only # and only operates on localhost.

Broker + User-side HTTP(S) proxy
by Mathias Ewald 28 Oct '13

28 Oct '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am using X2go broker with SSH proxy to have X2go servers sit behind the broker not directly reachable from the internet. Like this, I need Users have access to ports 443 (usually not a problem) and SSH (very often a problem). Problem is that users tend to sit behind transparent http/https proxies, so SSH won't get out. I would like to see everything being done through HTTPs so we can trick proxies. Is this going to be implemented in the near future or maybe even already possible somehow? cheers Mathias -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJSbgt3AAoJEA7RPiZyzgdIIRoP/A4d6rYcYk2NbNW7Zalc5viU u6lDE4KGPl9m7b7TbXs7X30FWGN/1wsyKFo262nrJHUX/UiiWjrIiSlRewxAg2dT AFsiNaLPfQc/GW/nSm0qOdAz/pCBlNTTeNa2HY/K6bOCyzv5kcsuqI8RjDZXV06E /tsvDeD/HR+C8ZHvsnHYDgmn12ftgpS1pJ/P5AM6ATTU3eKDC30OkJ4q46Ykim8W CbrMCDtElEUI3XXi6D33mYWKEAJyrIR10KvFMyZuG4o6E8lq0olT5FCFItyJTV+x i4KJWf/jAM3DDcJFNqICziSnLJcOTGt2PVBe8pZH9uidMVacztoJ0sBlOk/alTe1 nM4zUbToaGA4dwNPgBcJjdmywwXF7rXGqgp8Wm/VJ0u4mobm/NkNbsyWI5Q+TVcO huf250kDaDb8+eqIP23JttKr+FYT3eZ6D5KKIQeYeomgu/zopsPHSFi5gIexQclf 5aT87URNae+efIjayydjyP8DTEFh3Hw1QkdEgJYyfQlgh5lecYdsi+74G8MA3PoI NJpDUPsKtya4gIM3F3fTd3ucxYXXP6Z5qod7pDG6uIEwvImcbT9cbkNidnf01ROE g43lrBrhQ2C3pW2fhQi7skNI4Q2uA1wd1Qq8lPcTxoAl6wY6iS5Wut6aMwyJxmOm z5YtX+C+HkTb7kubtDtP =F+9b -----END PGP SIGNATURE-----

pyhoca-cli sound issues
by Tim Kruse 24 Oct '13

Hi all, I have weird sound issues with pyhoca-cli and need a hint, where to look :) Scenario: debian wheezy (uptodate) client with KDE running conncts to a debian wheezy (also uptodate) server with KDE. Following versions: root@client: ~ # dpkg -l | egrep 'x2go|pyhoca' ii pyhoca-cli 0.4.0.1-0~x2go1+wheezy~main~171~build1 all Command line X2Go client written in Python ii pyhoca-gui 0.4.0.8-0~x2go1+wheezy~main~1082~build1 all Graphical X2Go client written in (wx)Python ii python-x2go 0.4.0.8-0~x2go1+wheezy~main~1095~build1 all Python module providing X2Go client API ii x2goclient 4.0.1.1-0~x2go1+wheezy~main~427~build1 amd64 X2Go Client application (Qt4) root@server: ~ # dpkg -l | egrep 'x2go|pyhoca' ii x2go-keyring 2012.07.23+wheezy~main~17~build1 all GnuPG keys of all X2Go developers and the X2Go archive ii x2goagent 2:3.5.0.21-0+wheezy~main~423~build1 all X2Go agent ii x2goserver 4.0.1.6-0~x2go1+wheezy~main~712~build1 i386 X2Go server daemon scripts ii x2goserver-compat 4.0.1.6-0~x2go1+wheezy~main~712~build1 all X2Go server daemon scripts (backwards compatitbity to old client versions) ii x2goserver-extensions 4.0.1.6-0~x2go1+wheezy~main~712~build1 all X2Go server daemon scripts (extensions) ii x2goserver-xsession 4.0.1.6-0~x2go1+wheezy~main~712~build1 all X2Go server daemon scripts (Xsession runner) If I try to connect from client (within a fresh KDE session) to server with the following command, I don't have any sound in this x2gosession: pyhoca-cli --server $SERVER --new --command startkde --username $USR --sound pulse --geometry 1440x900 --link adsl --pack 16m-png-9 --kbd-layout de --kbd-type '105/de' Now I connect to the server (or another x2goserver, that doesn't matter) with x2goclient and there is sound. When I then connect again with above pyhoca-cli command, I have sound in this session. When I restart the local KDE Desktop on the client, I don't have any sound with pyhoca, until I connect with x2goclient ... I think, there is some process/program, that pyhoca-cli is not able to start, until x2goclient will start it, but I can't find it ... Help appreciatet :) So long, Tim
