    Hello,
    NoMachine do not provide feature to block commands. You can do this by configuring sudoers file for example.
    http://www.tecmint.com/disable-shutdown-and-reboot-commands-in-linux/

    About xscreenserver problem we are unable to reproduce the problem. Please check if changing DefaultDesktopCommand key value in /usr/NX/etc/node.cfg (on server side) from “/usr/bin/startxfce4” to “dbus-launch /usr/bin/startxfce4” will fix the problem. You need to have root permissions to change values in NoMachine configuration files.

    If this will not help some logs may be helpful. Please run command sudo grep xscreensaver /var/log/secure* and send us output to forum[at]nomachine[dot]com, referencing the topic as subject.

    Installation seems to be corrupted and we are unable to track the issue. Please reinstall it completely. You can do this by running those command in given order:
    sudo dpkg --purge nomachine
    sudo rm -rf /usr/NX/ /var/NX/ /etc/NX/
    sudo dpkg -i nomachine_6.11.2_1_amd64.deb

    First command:

    sudo cat /home/kevin/.xsession-errors > /home/kevin/logs.xsession-errors

    created file named logs.xsession-errors in your home directory.

    To collect nxserver logs please use those commands in terminal in given order:
    sudo sed -i 's/#SessionLogLevel 6/SessionLogLevel 7/g' /usr/NX/etc/server.cfg
    sudo /usr/NX/bin/nxserver --restart
    sudo tar cvfz NoMachine-log.tar.gz /usr/NX/var/log/

    Those command will create file named NoMachine-log.tar.gz in you home directory.

    Please send us those both files (NoMachine-log.tar.gz, logs.xsession-errors) to forum[at]nomachine[dot]com, referencing the topic as subject.

    bash: /home/kevin/.xsession-errors: Permission denied

    Try sudo cat /home/kevin/.xsession-errors > /home/kevin/logs.xsession-errors and send /home/kevin/logs.xsession-errors file to forum[at]nomachine[dot]com.

    About the second problem we will need NoMachine logs. To properly collect those logs you can take a look on this article https://www.nomachine.com/DT10O00163#1.1 and also we will be grateful if you send those logs to forum[at]nomachine[dot]com, referencing the topic as subject.

    We are still unable to reproduce the problem. Please check if NoMachine menu files are on the right direction by command sudo ls -ltr /usr/share/applications/ | grep NoMachine. If output will be empty you can fix it by command sudo cp /usr/NX/share/applnk/server/xdg/NoMachine-* /usr/share/applications/.

    To check what caused that problem file ~/.xsession-errors will be very useful. Please collect this file and send this information to forum[at]nomachine[dot]com.

    Hi, we are trying to reproduce the issue. Which version of desktop do you have? Cinnamon, MATE or XFCE?

    We will need your node.cfg file so we can verify if file is complete. You can find it at /usr/NX/etc/node.cfg, then send those information to forum[at]nomachine[dot]com, please.

    Also please verify if your default desktop command is set properly. First check what is the path to startxfce4 by using command which startxfce4 and then navigate to /usr/NX/etc/node.cfg and check if DefaultDesktopCommand key is set to path you got from which command. It should look similar to this:
    DefaultDesktopCommand "/usr/bin/startxfce4"

    I was able to reproduce the issue and unfortunately previous problem caused installation damage and it is hard to fix without reinstalling NoMachine.

    To completely reinstall NoMachine you need to use command sudo dpkg --purge nomachine then remove leftover catalog by command rm -rf /usr/NX/ and install it again. This should fix the problem with authentication.

    NoMachine setup is using command install for copying and setting files. As install is replaced on your machine files are installing incorrectly. Please rename /bin/install to for example /bin/inst (by command mv /bin/install /bin/inst) and try to install NoMachine again.

    As you can see your install command is replaced by some script that is trying to use apt. install is a basic command used on all linux distributions for copying files and should not be replaced. To fix this issue you need to check if install command is not replaced by alias (alias | grep install and if it’s on the list unalias install). If it’s not replaced by alias please change name of /bin/install file and try to install NoMachine again.

    Output from install --help command should look like this:

    install --help
    Usage: ./install [OPTION]... [-T] SOURCE DEST
      or:  ./install [OPTION]... SOURCE... DIRECTORY
      or:  ./install [OPTION]... -t DIRECTORY SOURCE...
      or:  ./install [OPTION]... -d DIRECTORY...
    
    This install program copies files (often just compiled) into destination
    locations you choose.  If you want to download and install a ready-to-use
    package on a GNU/Linux system, you should instead be using a package manager
    like yum(1) or apt-get(1).
    
    In the first three forms, copy SOURCE to DEST or multiple SOURCE(s) to
    the existing DIRECTORY, while setting permission modes and owner/group.
    In the 4th form, create all components of the given DIRECTORY(ies).
    
    Mandatory arguments to long options are mandatory for short options too.
          --backup[=CONTROL]  make a backup of each existing destination file
      -b                  like --backup but does not accept an argument
      -c                  (ignored)
      -C, --compare       compare each pair of source and destination files, and
                            in some cases, do not modify the destination at all
      -d, --directory     treat all arguments as directory names; create all
                            components of the specified directories
      -D                  create all leading components of DEST except the last,
                            or all components of --target-directory,
                            then copy SOURCE to DEST
      -g, --group=GROUP   set group ownership, instead of process' current group
      -m, --mode=MODE     set permission mode (as in chmod), instead of rwxr-xr-x
      -o, --owner=OWNER   set ownership (super-user only)
      -p, --preserve-timestamps   apply access/modification times of SOURCE files
                            to corresponding destination files
      -s, --strip         strip symbol tables
          --strip-program=PROGRAM  program used to strip binaries
      -S, --suffix=SUFFIX  override the usual backup suffix
      -t, --target-directory=DIRECTORY  copy all SOURCE arguments into DIRECTORY
      -T, --no-target-directory  treat DEST as a normal file
      -v, --verbose       print the name of each directory as it is created
          --preserve-context  preserve SELinux security context
      -Z                      set SELinux security context of destination
                                file to default type
          --context[=CTX]     like -Z, or if CTX is specified then set the
                                SELinux or SMACK security context to CTX
          --help     display this help and exit
          --version  output version information and exit
    
    The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
    The version control method may be selected via the --backup option or through
    the VERSION_CONTROL environment variable.  Here are the values:
    
      none, off       never make backups (even if --backup is given)
      numbered, t     make numbered backups
      existing, nil   numbered if numbered backups exist, simple otherwise
      simple, never   always make simple backups

    We have been unable to reproduce this problem. From logs you sent to us we have some conflicting information. One log says there are all files and have proper permissions set. Another log says that installation can’t find those files. Logs appear to be from two different machines, e.g one set from the connecting client, the other from the server. Also we did not received /usr/NX/var/log/nxinstall.log and /usr/NX/var/log/nxupdate.log which are essential to reproduce the problem in our lab.

    You can also create detailed debug file which should tell us everything about the problem. You can do it by executing command sudo sed -i '20s/^/set -x\n/' /usr/NX/scripts/setup/nxnode && sudo /usr/NX/scripts/setup/nxserver --update > nxlog.txt 2>&1 && sudo sed -i "/set -x/d" /usr/NX/scripts/setup/nxnode from your terminal and then send us nxlog.txt which will be in the place you executed command above.

    Please note that the logs must be from the machine where you are having installation problems.

    @rshuck Can you try new version 6.9.2 available on http://www.nomachine.com?
    If this will not help we will prepare another package with debug for you.

    Unfortunately we will need some additional information. Those should tell us where the real problem is. Please collect /usr/NX/var/log/nxinstall.log and /usr/NX/var/log/nxupdate.log (if it exist) files. Output from commands ls -ltr /usr/NX/etc/ and uname -a will be very useful. Send those information to forum[at]nomachine[dot]com, please.

    @rshuck We’ve prepared a package with debug. Package will be passed to you by a private message. Please update your existing NoMachine installation, collect file /Library/Application\ Support/NoMachine/var/log/nomachine_preinstall_logs.log and send those to forum[at]nomachine[dot]com, please.

    Additionally we have a method to install NoMachine package directly from the command line. You can find instructions in article.
