    I just installed nomachine_7.0.211_1_armhf.deb on a Raspberry Pi 4 running Buster with the latest upgrades.  I also installed NoMachine 7.0.211 on a MacBook Pro running MacOS Big Sur 11.1.

    When I log onto my Raspberry Pi from my Mac and click on the NoMachine icon in the taskbar, I see a menu pop up (just like before) with one of the menu items “Show server status”.  When I select this menu, nothing happens.

    When I go to the Raspberry icon in the upper left and select either Internet->NoMachine->NoMachine or Internet->Nomachine->Nomachine Service nothing happens.

    So…how can I determine the server status of NoMachine on my Raspberry Pi?  Before, I’d just use the Server Status menu from the NoMachine icon in the taskbar, but I can’t to this any more.  Something has changed between NoMachine versions 6 and 7.

    We cannot reproduce this problem. Is that Buster for armv7 (you can check your architecture with command uname -a)? Please open terminal and execute: /usr/NX/bin/nxplayer --dialog status and report what happened.

    Here is the result of uname -a:

    pi@w3yj-pi4-old:~ $ uname -a
    Linux w3yj-pi4-old.ddns.net 5.4.79-v7l+ #1373 SMP Mon Nov 23 13:27:40 GMT 2020 armv7l GNU/Linux

    This can’t be good, I get a core dump when checking the nxplayer status:

    pi@w3yj-pi4-old:~ $ /usr/NX/bin/nxplayer –dialog status
    Segmentation fault (core dumped)

    Would the core dump be of any value to you?  Unfortunately it is too large to upload to the forum.

    Hi hpb,

    We are still unable to reproduce the problem.

    Logs would indeed be useful, you can send them to forum[at]nomachine[dot]com, referencing the topic as subject.

    We need logs of player and server both from rpi machine, plus server.cfg and node.cfg. – to check if some option(s) were changed, which provokes the problem.

    Thanks!

    I completely removed NoMachine:

    sudo dpkg –remove nomachine

    For good measure, I deleted the /usr/NX directory:

    pi@w3yj-pi4-old:/usr $ sudo rm -rf NX

    I then reinstalled NoMachine:

    i@w3yj-pi4-old:~ $ sudo dpkg -i nomachine_7.0.211_1_armhf.deb

    Logged on with NoMachine, and I have the same problem, unable to click on the NoMachine icon in task bar and see Service Status window.

    Here are contents nxserver.log.  I have verified that htd.cfg does not exist.

    One last thing to think of…I am unable to view the NoMachine machine status while logging in with NoMachine.  This is a headless Raspberry Pi so it’s a pain for me to hook up an external monitor.  It is possible that the security of NoMachine is preventing me from viewing the status window remotely?  If so, this is a change from Version 6 on my other systems.

    Can you please send the logs directly to forum[at]nomachine[dot]com. They were possibly too big to be accepted here.

    Yes, I would like a binary to try.  Thank you so much!  This is great customer service.

    For what it’s worth, I could not find anything in various logs when this problem happens.

    For what its worth, I have exactly the same problem. The server window or main window will not show either via VPN or on direct video display to the Pi.

     

    I’ve tried uninstalling, reinstalling many times, updating raapbian and some other settings but just get the segmentation error. Very rarely it works one after fresh reinstall but then stops again.

    Thanks!

    Would you like to receive the patched binary for testing as well? 🙂

    I already received a link to a patched nxplayer.bin from Carin.  I will download and test later today.  Thank you!

    The binary emailed to me by Carin fixed the problem.  I am now able to view my system’s status.  Thank you!
