by Ramunas Berulis 07 Jan '13

Hello I tried to test x2goplugin (Firefox plugin) and used instructions on http://www.x2go.org/doku.php/wiki:components:x2goplugin?s[]=plugin I have build website saying "This website will offer you a plugin named ..." but it does not work. Unfortunately, the following URLs do not work: http://www.x2go.org/doku.php/wiki:components:x2goplugin-example http://plugin.x2go.org/download/x2goplugin_linux32.xpi http://plugin.x2go.org/media/x2goplugin.js Can you help me to find x2goplugin_linux32.xpi and x2goplugin.js ? It seems that plugin.x2go.org is not working any more. Regards Ramūnas Berulis

New Bug/Issue with X2Go - NOT related to latest client release
by Stefan Baur 01 Aug '12

01 Aug '12

Situation: Client: Windows 7 (32-Bit), German X2Go Client versions tested: http://code.x2go.org/releases/binary-win32/x2goclient/x2goclient-3.99.2.1-r… (latest) http://code.x2go.org/releases/binary-win32/x2goclient/x2goclient-3.99.2.0-r… (old) Server: Debian Squeeze, 32-Bit, with additional repositories for newer iceweasel and icedove releases: sources.list-snippet: # Ice*-ESR deb http://backports.debian.org/debian-backports squeeze-backports main deb http://mozilla.debian.net/ squeeze-backports iceweasel-esr deb http://mozilla.debian.net/ squeeze-backports icedove-esr Affected Iceweasel Version: 10.0.3 (ESR) Shockwave Flash: File: libflashplayer.so Version: Shockwave Flash 11.1 r102 Problem description: When opening two tabs in Iceweasel, and accessing Youtube in one, the rectangle containing the video player/flash applet is carried over to the new tab, where it blocks the view. This does *not* happen with the Iceweasel version from stock Debian Squeeze. This *does* happen with both X2Go client versions listed above. Is anybody out there running Iceweasel 10.0.3 (ESR) with the above-mentioned flash version on a "real" display screen (i.e. a Linux computer hooked up to a physical display, not via X2Go)? If so, could you please check if you're experiencing the issue as well: 1) On the real display screen? 2) Via X2Go? I'm curious if this is a bug in Iceweasel or in X2Go. -Stefan

X2go connection problem to a Vserver
by senrabdet＠aol.com 30 Jul '12

30 Jul '12

To Whom It May Concern: We are trying to get x2go to work with a Vserver instance but cannot connect. We've done some looking at x2go posts into the error, but we're not sure the responses apply to using Vserver and are still looking for some help (apologies if we should have been able to find this on our own). The error is first: "X2go-51 The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." The window includes an "OK" button. If we press the OK button, we get to the x2go login screen where you can enter a password...if we enter the password, we get: "Error Connection failed channel_open_session failed - Writing packet: error on socket (or connection closed): Broken pipe." On the client, in the "sessions" file we see: Loop: PANIC! The remote NX Proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. In both the client "options" file, the cookie looks to be the same as the cookie in the server FYI - we can ping the Vserver instance, and we can ssh into the Vserver successfully, ping 8.8.8.8 from there etc. Also, initially when this wouldn't work, we though maybe we had issues with how we had set up desktops in the Vserver (which is still possible: we're using gnome, gdm) but when we spun up another Vserver and set up VNC, it serves the desktop correctly so at first blush this seems to be a networking/ports/firewall/sshd/routing type of issue. However, we're still having trouble getting a regular X session to run over SSH.....but are assuming at the moment (possibly incorrectly) that the X2go errors we're getting are an issue on their own, possibly in addition to running an X session on a Vserver. ...And...at various points (though not on the current server instances), we set up x2go on the host and could connect to that over our LAN. Again, the current instances only have x2go running on the Vserver guest. SETUP 1) OpenSsh-Server We have openssh-server running only on the Vserver guest (we tried having it on the host too, but that didn't seem to matter). We are using port 22. We've tried using a ListenAddress xxx.xxx.xxx.xxx which is the IP of the host, but this doesn't seem to matter. 2) X2go Likewise X2go server is only installed on the Vserver instance (though again we tried it on both the host and guest with no differences we could see). We set up x2go on Ubuntu 10.4 server (both host and guest)using: apt-get install python-software-properties add-apt-repository ppa:x2go/stable apt-get update apt-get install -y x2goserver apt-get install -y x2goserver-extensions 2) We made sure from a client that we can successfully ssh. Again, this may not mean anything, but we can VNC to the guest desktop successfully. 3) We try x2go from a linux client (Ubuntu 10.10, x2go version 3.99.1.1) and get the errors described above. Q: are we using too old a client version? Q: is this a firewall issue - we don't have iptables or ufw set up Q: is this a matter of changing entries in hosts, hostname, network/interfaces, etc on the Vserver and/or host? FYI some time back Mike Garbriel responded to one of our inquires (thanks Mike) on using chroot (http://comments.gmane.org/gmane.linux.terminal-server.x2go.devel/3720) that mentions (we're assuming for the sake of our example that using port 22 in sshd_config meet this suggestion): If you work with pure chroots then install x2goserver into each chroot. Configure the chroot's SSH daemon to listen on a specific SSH port. So at the end you have chroot-1 - <port-1> chroot-2 - <port-2> Setup up X2Go client to connect to your host, for chroot-1 choose <port-1> in your X2Go client configuration, <port-2> for chroot-2, etc. Help appreciated! Thanks, Ted

Re: [X2Go-Dev] [X2Go-User] Unable to open a session when default shell is /bin/tcsh

Hi Seba, (...diverting this thread to the x2go-dev mailing list...) On Mi 25 Jul 2012 17:24:53 CEST sebastien seba wrote: > When a user have /bin/tcsh for default shell, > this user unable open session on centos 6.3 and x2goserver > > The error message is “connection failed > export: command not found.” There is no workaround, it is (still) a bug in x2goclient and also was a bug in python-x2go. The bug in python-x2go has been fixed with this commit: http://code.x2go.org/gitweb?p=python-x2go.git;a=commitdiff;h=588ba614baf0ba… The bug in x2goclient is the same and should be fixable with something like diff --git a/sshprocess.cpp b/sshprocess.cpp index e8f0ea6..06de599 100644 --- a/sshprocess.cpp +++ b/sshprocess.cpp @@ -130,7 +130,8 @@ void SshProcess::tunnelLoop() void SshProcess::startNormal(const QString& cmd) { - masterCon->addChannelConnection(this, cmd); + QString shcmd = "sh -c \""+cmd+"\""; + masterCon->addChannelConnection(this, shcmd); connect(masterCon,SIGNAL(stdOut(SshProcess*,QByteArray)),this,SLOT(slotStdOut(SshProcess*,QByteArray))); connect(masterCon,SIGNAL(channelClosed(SshProcess*)), this,SLOT(slotChannelClosed(SshProcess*))); } However, I am not a C++ coder and the above is not correct.

Greetings and a lot of questions.

Hi! I am working on a X2go client for Android/iOS the client gui is done, i am working on the libraries for ARM under android and iOS. i took the x2goplugin (the little´s standalone x2goclient) as base for my development. it requires this files: libx2go.so libXcomp.so libXcomp.so.3 libXcomp.so.3.4.0 nxproxy sftp-server sshd sftp-server and sshd are done (not exactly rocket science), but i need to build the others, for libXcomp.so in www.nomachine.com/sources.php i can download a pack of source code. ¿will it work with x2go? ¿is it different? where can i download the official x2go source for those files? about libx2go.so ¿wich source package provides it? Thanks in advance for any help. (All the work i am doing will be documented so, other people can get working x2goclients and when i get my client finished i will be glad of make it available for all x2gousers).

Problems with AltGr
by Sven Köhler 24 Jul '12

24 Jul '12

Hi, I use x2goclient to connect to a x2goserver, both as installed by gentoo linux. I believe the gentoo versions are "special" in the sense that it uses the NoMachine's version of the nxagent. Now when I connect and I press AltGr+<, then the result should be the character | but the actual result is < The problem also occurs with the @ character, which is normally obtained by pressing AltGr+@, but in just results q instead of @. Any ideas? The session settings seem to be OK. It doesn't matter whether I tell x2goclient to keep keyboard settings or whether I explicitly configure de layout. Server-side is nx-3.5.0.14 (includes nxagent) x2goserver-3.1.1.3 Client-side is net-misc/nx-3.5.0.14 x2goclient-3.99.2.1 Regards, Sven Köhler

IPv6 and IPv4
by Christoph Egger 23 Jul '12

23 Jul '12

Hi all! I was using x2go on my notebook on a IPv6 enabled network and the x2goserver also has v6 connectivity. Everything went fine so far, however when I am in an IPv4 only network (no v6 default route, only link-local address) x2go to the same server fails with "Connection timed out" while I am able to connect to the x2goserver flawlessly via ssh over IPv4. If I start the local v6tunnel on my notebook connecting to the x2goserver works again. Regards Christoph
