My setup is as follows: Server OS: Ubuntu 12.04 LTS FreeXN Version: NXSERVER - Version 3.2.0-74-SVN OS (GPL, using backend: 3.5.0) Client OS: Windows 7 NX Client: NoMachine NX Client for Windows Version 3.5.0-9 The clients can all connect and disconnect sessions on the server. I have my shadow client configured so the Desktop is set as "Shadow". Once connected I get a list of available sessions. If I select a session and press Attach I get an error message "The NX Client received an error from the server. Please check the details for more information". I've listed the contents at the bottom of this email. If I check the suggested session file. The contents of which are: Error: Aborting session with 'Server is already active for display 2003 If this server is no longer running, remove /tmp/.X2003-lock and start again'. If I remove the lock file and retry I still get the errors and the session file now contains... Error: Aborting session with 'Cannot establish any listening sockets - Make sure an X server isn't already running'. I'm not sure what it is that I've missed or got wrong in my setup. Can anyone help?

David 2013-04-19T17:57:24 http://comments.gmane.org/gmane.network.freenx.general/9797 <pre>I have googled and been to !M KB without luck, so I guess I need to ask you good people! I have a 12.04 Ubuntu server with freenx installed and working fine for X apps. I can connect from remote machines and run either a DE (e.g., lxde) or individual windowed apps (LibreOffice, Firefox, etc.). I am using the NX client on my 2 remote machines, one Ubuntu, one Windows 2000. Now I want to connect to the freenx server and have it proxy a VNC session from a Windows machine to my remote client. To clarify... the freenx server (aka "proxy machine") and the windows machine running a VNC server (aka "VNC host") are on the same (workplace) network. From home I want to NX from my "remote client" to the nx proxy machine and be able to manipulate the desktop of the VNC host. After "connected", "authenticated" and "downloading session data" confirmation messages, I get "connection error" message. I've turned debug to level 7 via node.conf on the server. Checking the session log in .nx/ under my home directory on the server, I see a single line: /usr/lib/nx/nxnode: line 818: /usr/lib/nx/nxviewer: No such file or directory First, please correct me if I have a fundamental misunderstanding since most of the vnc related threads I've found concern accessing the display :0 session on the freenx proxy machine, in a 2 machine scenario. I'm attempting a 3 machine scenario, which the docs seem to show is a normal use case. From my reading it sounds to me like nxviewer is no longer used, and vncviewer should be sufficient. vncviewer is installed and working on the server, nx proxy machine. I've also confirmed that x11vnc, xvnc4viewer, freenx-vnc and tightvncserver are all now installed. "nxpasswd" also exists in /usr/lib/nx. I've toyed with all the relevant node.conf settings I can find, namely "ENABLE_EXTERNAL_NXVIEWER", "COMMAND_VNCVIEWER", etc. But that's probably the wrong path.... the real question to me is why is it trying to run nxviewer instead of vncviewer? I am afraid I'm doing something stupid, but can't for the life of me figure out what :-) Any help Very Much Appreciated !!! Thanks, MikeM PS: I sudo apt-get dist-upgrade frequently :-) ________________________________________________________________ Were you helped on this list with your FreeNX problem?

Now I've just installed freenx on TWO different CentOS6.x 64-bit (x64) servers, but neither is working. In both cases, I can login, and get an empty, black X11 window. I know it's working that far, because I can connect to the server, set my DISPLAY to :100x and run /etc/X11/xinit/Xsession to start my window manager properly and use my NX session. Obviously, that's not good enough, and I need to get NX launching the session on login like it should, but nothing in the logs (~/.nx/ and /var/log/nx/) indicates any problem. --check is pretty worthless, as it always complains. I wrote a tiny shell script that, when run, just creates a file in /tmp, filled with the date and a few user variables. If I tell the nxclient to run that command as my shell, it is NEVER executed, as I've never seen a file show up, after dozens of attempts. I have SELINUX disabled, and nothing is notably pathological about my installations... One of the two is pretty plain vanilla CentOS6.x. Now I'm trying with OpenNX, but no change. I'd appreciate any help tracking down where this process is hanging-up. I'm amazed there aren't more reports of problems like this, because I'm seeing a 100% failure rate on CentOS6. ________________________________________________________________ Were you helped on this list with your FreeNX problem?

For example I can configure sshd_config with: ForceCommand /bin/bash ..which subsequently prevents, scp, rsync over ssh, and even something like "ssh remoteHost 'cat /etc/passwd'", but still allows interactive ssh sessions with a bash shell. Does anyone have any ideas on how I can provide NX sessions to a remoteHost, yet prevent any data transfers to/from that sameHost over ssh? Using the example above can I ForceCommand the NX tunneling bits, and if so what are they? Or can NX be configured not to use ssh? Thank you for your time. Mark Christian Confidentiality Notice.

There is a also a Python based x2go client called PyHoca. All is Open Source x2go audio (pulseaudio), printing, remote file shares etc. all work well without tinkering and it was for me a lot simpler to install. If you use debian or ubuntu the installation takes 5 minutes *on server* 1. sudo add-apt-repository ppa:x2go/stable 2. sudo apt-get update 3. sudo apt-get install x2goserver x2goserver-xsession 4. then add all users to the x2gouser "group" - sudo adduser &lt;username&gt; x2gouser *on linux client* 1. sudo add-apt-repository ppa:x2go/stable 2. sudo apt-get update 3. sudo apt-get install x2goclient only other thing you "might" have to do is edit your /etc/ssh/sshd_config file to match the following.. then restart ssh (sudo /etc/init.d/ssh restart) *# Change to yes to enable challenge-response passwords (beware issues with* *# some PAM modules and threads)* *ChallengeResponseAuthentication yes* * * *# Change to no to disable tunnelled clear text passwords* *PasswordAuthentication yes* some linux versions "may" have those 2 entries set to NO or commented out (same as NO). *Thats it !* If you are on Windows just download &amp; install the Windows version as you would any other Windows app. Mac is supported but I don't use a Mac so you'd have to ask on the x2go Users mailer how to do it. When you start the x2go client you create a "session" it will ask you for: IP address or DNS name of the x2go server login ID and you need to select what "desktop" you use (Unity, Gnome, xfce, lxde etc) Click the "connection" tab and you will see a slider. The purpose of that is to tell x2go client/server how much compression to utilize. If you have a fast internet (I have 17 Mbps)... just move it all the way to LAN. then save the profile Click the newly made "session" icon picture on the right enter your password answer the linux question about an "unknown server" and your desktop should pop up. *NOW... all that being said realize that with BOTH Ubuntu Unity and with ANY Gnome system the following:* Starting in Ubuntu 12.10 there is NO Unity 2D any longer Starting with Gnome 3.0 there is NO gnome-fallback any longer NO Matter WHAT remote desktop you use (NX, FreeNX, x2go etc) ... as far as I know... NONE of them will be capable of support Unity 3D or Gnome 3.0 remote desktops because BOTH of those will be using HW video acceleration which as of now no solution is in place. NoMachine's website has a notice about this as well. So... that being said if EITHER of the above apply to you the choices are stay with your distro where you can use Unity-2d or gnome-fallback. -or- use one of the other "desktops" (lxde, xfce etc)... For Ubuntu the 12.04 Long Term Support (LTS) release is good for 6 more years so if you use that you can just select Unity or Gnome in x2go and you should be good to go because x2go will auto-magically use Unity-2D or gnome-fallback ... whichever is the case I'm assuming x2go on Debian is the same because some of the core developers use Debian. brian ---------- Forwarded message ---------- From: &lt;freenx-knx-request&lt; at &gt;kde.org&gt; Date: Sat, Jan 26, 2013 at 7:00 AM Subject: FreeNX-kNX Digest, Vol 101, Issue 16 To: freenx-knx&lt; at &gt;kde.org Send FreeNX-kNX mailing list submissions to freenx-knx&lt; at &gt;kde.org To subscribe or unsubscribe via the World Wide Web, visit https://mail.kde.org/mailman/listinfo/freenx-knx or, via email, send a message with subject or body 'help' to freenx-knx-request&lt; at &gt;kde.org You can reach the person managing the list at freenx-knx-owner&lt; at &gt;kde.org When replying, please edit your Subject line so it is more specific than "Re: Contents of FreeNX-kNX digest..." ________________________________________________________________ Don't forget to check the NX Knowledge Base: http://www.nomachine.com/kb/ Please also check the FreeNX Wiki+FAQ for hints. http://openfacts.berlios.de/index-en.phtml?title=FreeNX_FAQ ________________________________________________________________ Today's Topics: 1.

Is x2go compatible with the other array of NX clients? It looks like it uses the same NX agent components, and since we use a combination of FreeNX and the commercial NX offerings, I like the fact that one client will (mostly) work with both of the servers. -Nick ________________________________________________________________ Were you helped on this list with your FreeNX problem?

I am having trouble finding the needed information online anywhere. NX version: NX&gt; 1000 NXNODE - Version 3.2.0-74-SVN OS (GPL, using backend: 3.3.0) I have a need to do two things. (in FreeNX or commercial NX server) 1.Force an application to be started on session start with no desktop (this I have partly got working by using the NODE_AUTOSTART="/usr/bin/firefox" setting in node.cfg (Not without desktop showing however) it seems the ENABLE_ROOTLESS_MODE="1" does not function as I had thought it would. 2.Only allowing this application to be launched, all other NX client configured commands should be overridden so that this one application starts. So in short, I want the user to be presented with a login application when they are logged on through the NX server, also I want the desktop to be hidden and not usable for the end user. I have not found any working way to do this, some information I found about nxacl that I could not get working in our FreeNX so far. I was also not able to do this in the Commercial NX server. Has anyone tried something like this and got it working. I would be grateful for any hints.

First, let me state that getting NX Player working with FreeNX is a must - we need to connect Mac clients to our servers, and, since the only Intel-based version of the NX Client for Mac is NX Player 4.x, going back to the 3.5 client is not an option, at least for Mac-based clients. So, for those who would suggest using the "known good" versions of NX Client 3.5.x, that's not really feasible in my situation. So, here are the software versions I'm using: - OpenSuSE 12.1 - FreeNX 0.7.3, plus a few patches - NX 3.5.0 - NX Player 4.0.181 Preview 6 (currently on Linux) As far as the client goes, I can successfully connect my NX Player client to the NoMachine Virtual Workstation for Linux 4.x preview software, so I'm fairly certain that network issues can be ruled out here. Also, I can successfully connect to FreeNX running on CentOS5, so it actually seems to be some interaction here between FreeNX and something in OpenSuSE. Hopefully someone can point out what, or at least help me better nail it down. Here's what I'm seeing: - Connections fail *most* of the time - maybe 1 connection in 10 works perfectly fine, but the rest fail with the exact same error. - It does not matter what Window Manager I try to use - KDE4, XFCE4, GNOME - all seem to fail equally well. - This is not trying to resume an existing session, just create a new one. - I've tried local users and network users on my systems, and that doesn't really seem to make a difference, either, so not a home directory, LDAP, or NFS issue. - I see the following message on the screen on NXPlayer when I try to create a new, GNOME, for example, session: The connection with the server was lost. Error is 22: Invalid argument. - If I choose the option to save the logs and then go look at the session logs, I see the following: 28343 5201 19:57:45 290.914 ProxyParser/ProxyParser: ERROR!

First, it seems like the server and client are both pointing the finger at each other saying it's the other's fault. But then there's this error about Unable to open display?? I should also note that I have tried and successfully been able to do the "ssh -X &lt;hostname&gt; nxagent" test - works fine, once it's running I can open up items inside that display, etc. Also, on NXPlayer, if I do a custom session and specify xterm as the command to run, that seems to work every time. So, perhaps it's a timing thing - the window manager trying to start before X is available, or maybe X is timing out too fast before the window manager can start? Also, what happens in "Stage '10'"? This is a fairly consistent error - failure negotiating the s ession in stage '10' - but I cannot find any reference to this error around, nor can I figure out what stage 10 is supposed to be.

Needless to say, I finally got X working again, but now, I'm unable to login via freenx using my typical user account. When I do login, the authentication is successful, and I'm just left with a black screen with a mouse cursor. I know X is running, as the process ID shows up. So, to start, I deleted all gnome cache, deleted all sessions, restarted the nxserver and freenx-server service, and deleted stuff in the /tmp/user-orbit folder. None of that helped. What's weird is that I created a new user, added the user to the allowed SSH list, and tried connecting using the same settings. With the new user, I can get in and see my gnome desktop. I'm running Ubuntu 10.04. I've looked at countless forum posts where others have had the same problem and tried everything. Nothing has fixed it for the main user account. I have logging enabled in the nxserver, and no errors are reported in the nxserver.log or in the session cache files themselves. Can anyone suggest anything else I can try or where to start? ________________________________________________________________ Were you helped on this list with your FreeNX problem?

After some digging I came up with the following line in the script /usr/bin/nxdesktop_helper on the freenx server: set -- -u "$agent_user" -k "$agent_keyboard" -d "$agent_domain" -f -s "$windows_app" $AGENT_EXTRA_OPTIONS_RDP "$agent_server" and the value of $windows_app apparently is "/usr/bin/nxdesktop_helper", so the terminal server tries to run the said program on login and pathetically fails to do so... voilà the user is immediately logged out. As a workaround I just deleted the '-s "$windows_app"' bit in the above line and connecting to my terminal server works fine: set -- -u "$agent_user" -k "$agent_keyboard" -d "$agent_domain" -f $AGENT_EXTRA_OPTIONS_RDP "$agent_server" I fail to see though whether there are scenarios where the -s parameter for rdesktop is actually useful? (Trying to run '/usr/bin/nxdesktop_helper' on a windows machine obviously isn't...)

I finally succeeded in setting up a freenx server and so far everything is working fine. The goal is ultimately to allow the user in a samba-Domain to access some Windows-Clients through freenx. As I understand it this is internally accomplished through the rdesktop program which allows some handy options (like -d for the logon-domain and -r disk: for adding shares). Now my question obviously is whether and how I can add those options for rdesktop to the nxserver configuration.

Nobody replied, but others may have encountered the same annoyance. Many OS installations later, it came back to haunt me, but this time I realized the solution to the problem. I post in case anybody else encounters it: When using gnome on linux, there is an option under 'Preferences' ---&gt; 'Mouse and Touchpad' to 'Show position of pointer when the Control key is pressed'. (Handy when using a notebook in a high-glare environment.) When that box is un-checked there longer is any need to escape the ctrl key in NX sessions. -Mark Original posting: [FreeNX-kNX] ctrl key behavior differs for same client on different machines *Mark Wilber*wilber at ssl.berkeley.edu&lt;mailto:freenx-knx%40kde.org?Subject=%5BFreeNX-kNX%5D%20ctrl%20key%20behavior%20differs%20for%20same%20client%20on%20different%0A%09machines&amp;In-Reply-To=&gt; /Fri Aug 8 03:32:18 CEST 2008/ ------------------------------------------------------------------------ I've fruitlessly looked all over for a solution to this. While running nxclient-3.2.0-14 on my Fedora 9 desktop to access nxserver 3.0.0-74 on a Fedora Core 4 machine things work beautifully, but when using the identical client (installed from the same .rpm file) on my notebook -- also running Fedora 9 -- there results an annoying ctrl key behavior. On my notebook, the ctrl key works (but only sometimes) if preceded by the alt key. `Escaping' a ctrl key is pretty useless for someone who lives inside emacs. Anybody know a fix/workaround that will liberate my ctrl key? thanks, -Mark -- Mark Wilber / Assistant Research Physicist / Space Sciences Laboratory University of California, Berkeley 94720 / 510-643-6896 / 510-643-8302 -- AST:7731^29u18e3 ________________________________________________________________ Were you helped on this list with your FreeNX problem?
