NoMachine do not provide feature to block commands. You can do this by configuring sudoers file for example.
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
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
sudo cat /home/kevin/.xsession-errors > /home/kevin/logs.xsession-errorsand send
/home/kevin/logs.xsession-errorsfile 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-errorswill 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?February 10, 2020 at 12:25 in reply to: Cannot install latest version (18.104.22.168) on Ubuntu 16.04 #25552
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 startxfce4and then navigate to /usr/NX/etc/node.cfg and check if DefaultDesktopCommand key is set to path you got from
whichcommand. It should look similar to this:
DefaultDesktopCommand "/usr/bin/startxfce4"February 7, 2020 at 17:12 in reply to: Cannot install latest version (22.214.171.124) on Ubuntu 16.04 #25530
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 nomachinethen remove leftover catalog by command
rm -rf /usr/NX/and install it again. This should fix the problem with authentication.February 5, 2020 at 16:59 in reply to: Cannot install latest version (126.96.36.199) on Ubuntu 16.04 #25500
NoMachine setup is using command
installfor copying and setting files. As
installis 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.February 4, 2020 at 16:57 in reply to: Cannot install latest version (188.8.131.52) on Ubuntu 16.04 #25476
As you can see your
installcommand is replaced by some script that is trying to use
installis 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 installand 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.
install --helpcommand 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 GNU coreutils online help: <http://www.gnu.org/software/coreutils/> Full documentation at: <http://www.gnu.org/software/coreutils/install> or available locally via: info '(coreutils) install invocation'January 21, 2020 at 16:47 in reply to: Cannot install latest version (184.108.40.206) on Ubuntu 16.04 #25336
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/nxupdate.logwhich 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/nxnodefrom your terminal and then send us
nxlog.txtwhich 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.January 14, 2020 at 10:13 in reply to: Cannot install latest version (220.127.116.11) on Ubuntu 16.04 #25224
Unfortunately we will need some additional information. Those should tell us where the real problem is. Please collect
/usr/NX/var/log/nxupdate.log(if it exist) files. Output from commands
ls -ltr /usr/NX/etc/and
uname -awill 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.logand 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.
