NX Server Installation
Instructions

1. NX Server Installation Instructions

2. NX Server Installation Instructions for Linux Platforms

The following NX Server packages are available:

• RPM, DEB and Compressed TAR for 32bit architecture
• RPM, DEB and Compressed TAR for 64bit architecture
• RPM, DEB and Compressed TAR for 32bit architecture for earlier Linux versions

2.2 Installing the NX Server RPM Package

Open an xterm terminal or similar, move to the directory where you have downloaded the package from the NoMachine Web site and install the package using the RPM utility:

# sudo rpm -ivh nxserver-X.Y.Z-W.i386.rpm

Otherwise you can use the graphical package manager provided by your Linux distribution.

2.3 Updating the NX Server Installation from RPM Package

It is highly recommended you disable access to new NX sessions and terminate all running sessions before proceeding with the upgrade of the server.

To disable access to new NX sessions, open a xterm or similar and run the following command. Please note that this will not affect users' ability to login to the system by other means (f.e. ssh or telnet):

# sudo /usr/NX/bin/nxserver --stop

You might want to issue a warning to all connected users to inform them of the operation. Run:

# sudo /usr/NX/bin/nxserver --broadcast "Your message here"

Then, after the warning, terminate all the running sessions:

# sudo /usr/NX/bin/nxserver --shutdown

# sudo tar cvzf /root/nx-BACKUP.tar.gz /usr/NX
# sudo chmod 0600 /root/nx-BACKUP.tar.gz

Next move to the directory where you have downloaded the package from the NoMachine Web site and run:

# sudo rpm -Uvh nxserver-X.Y.Z-W.i386.rpm

2.4 Removing the NX Server Installation from RPM Package

Open an xterm terminal or similar and uninstall the package using the rpm utility:

# sudo rpm -e nxserver

2.5 Installing the NX Server DEB Package

Open an xterm terminal or similar, move to the directory where you have downloaded the package from the NoMachine Web site and install the package using the dpkg utility:

# sudo dpkg -i nxserver_X.Y.Z-W_i386.deb

2.6 Updating the NX Server Installation from DEB Package

It is highly recommended you disable access to new NX sessions and terminate all running sessions before proceeding with the upgrade of the server.

To disable access to new NX sessions, open an xterm or similar and run the following command. Please note that this will not affect users' ability to login to the system by other means (f.e. ssh or telnet):

# sudo /usr/NX/bin/nxserver --stop

You might want to issue a warning to all connected users to inform them of the operation. Run:

# sudo /usr/NX/bin/nxserver --broadcast "Your message here"

Then, after the warning, terminate all the running sessions:

# sudo /usr/NX/bin/nxserver --shutdown

Make a backup of your current NX installation and protect sensitive information that may be present inside the TAR archive by making the backup readable only by the 'root' user:

# sudo tar cvzf /root/nx-BACKUP.tar.gz /usr/NX
# sudo chmod 0600 /root/nx-BACKUP.tar.gz

Next move to the directory where you have downloaded the package from the NoMachine Web site and run:

# sudo dpkg -i nxserver_X.Y.Z-W_i386.deb

The dpkg utility will automatically uninstall the old version present on the system and install the new one.

2.7 Removing the NX Server Installation from DEB Package

Open an xterm terminal or similar and run:

# sudo dpkg -r nxserver

2.8 Installing the NX Server Compressed TAR Package

Open an xterm terminal or similar. You should have downloaded the tar.gz package to the /usr directory. If not, move the package to the /usr directory. For example:

# sudo mv nxserver-X.Y.Z-W.i386.tar.gz /usr

Then extract the archive:

# cd /usr
# sudo tar xvzf nxserver-X.Y.Z-W.i386.tar.gz

and run the setup script for nxserver:

# sudo /usr/NX/scripts/setup/nxserver –-install

2.9 Updating the NX Server Installation from Compressed TAR Package

It is highly recommended you disable access to new NX sessions and terminate all running sessions before proceeding with the upgrade of the server.

To disable access to new NX sessions, open an xterm or similar and run the following command. Please note that this will not affect users' ability to login to the system by other means (f.e. ssh or telnet):

# sudo /usr/NX/bin/nxserver --stop

You might want to issue a warning to all connected users to inform them of the operation. Run:

# sudo /usr/NX/bin/nxserver --broadcast "Your message here"

Then, after the warning, terminate all the running sessions:

# sudo /usr/NX/bin/nxserver --shutdown

Make a backup of your current NX installation and protect sensitive information that may be present inside the TAR archive by making the backup readable only by the 'root' user:

# sudo tar cvzf /root/nx-BACKUP.tar.gz /usr/NX
# sudo chmod 0600 /root/nx-BACKUP.tar.gz

Next ensure that the downloaded package is in the /usr directory, extract the archive and run the setup script for nxserver:

# sudo tar xvzf nxserver-X.Y.Z-W.i386.tar.gz
# sudo /usr/NX/scripts/setup/nxserver –-update

This operation will overwrite all the files from the previous installation.

2.10 Removing the NX Server Installation from Compressed TAR Package

This operation will remove both the NX Client, NX Node and NX Server installations. Open an xterm terminal or similar. Run the setup scripts for uninstalling the server and the node, and remove the installation directory:

# sudo /usr/NX/scripts/setup/nxserver –-uninstall 
# sudo /usr/NX/scripts/setup/nxnode –-uninstall 
# sudo rm -rf /usr/NX

3. NX Server Installation Instructions for Solaris Platforms

Open a terminal and move to the directory where you have downloaded the package from the NoMachine Web site. Expand the package archive and install it using the pkgadd utility :

# sudo gunzip nxserver-X.Y.Z-W.sparc.gz
# sudo pkgadd -d nxserver-X.Y.Z-W.sparc

3.2 Updating the NX Server Installation

It is highly recommended you disable access to new NX sessions and terminate all running sessions before proceeding with the upgrade of the server.

To disable access to new NX sessions, open an xterm or similar and run the following command. Please note that this will not affect users' ability to login to the system by other means (f.e. ssh or telnet):

# sudo /usr/NX/bin/nxserver --stop

You might want to to issue a warning to all connected users to inform them of the operation. Run:

# sudo /usr/NX/bin/nxserver --broadcast "Your message here"

Then, after the warning, terminate all the running sessions:

# sudo /usr/NX/bin/nxserver --shutdown

Make a backup of your current NX installation and protect sensitive information that may be present inside the TAR archive by making the backup readable only by the 'root' user:

# sudo gtar cvzf /root/nx-BACKUP.tar.gz /usr/NX
# sudo chmod 0600 /root/nx-BACKUP.tar.gz

The next step is to remove the previous installation, otherwise the installation will fail because only a single instance of the package is supported at one time on the same system:

# sudo pkgrm NXserver

Finally, expand the package archive and install it using the pkgadd utility:

# sudo gunzip nxserver-X.Y.Z-W.sparc.gz
# sudo pkgadd -d nxserver-X.Y.Z-W.sparc

3.3 Removing the NX Server Installation

Open a terminal and remove the NX server installation using the pkgrm utility:

# sudo pkgrm NXserver
