NoMachine, in order to cover the widest number of versions for the supported Linux Operating Systems, offers three different kinds of NX Client packages:

• NX Client package for 32bit architecture
• NX Client package for 64bit architecture
• NX Client package 32bit architecture for earlier Linux versions

The NX Client for Linux packages ship a nxclient executable, which is statically linked against QT, that links dynamically with GLIBC and requires that libstdc++ version 6 is present on the system. Since NX Client provides support for font antialising, it requires also that the XFT libraries (libfontconfig.so.1 and libXft.so.2) are present on the system.

Libraries required on the local system in order to install NX Client are:

- ld-linux.so.2
- libdl.so.2
- libpthread.so.0(GLIBC_2.0)
- libaudiofile.so.0
- libdl.so.2(GLIBC_2.0)
- libpthread.so.0(GLIBC_2.1)
- libcrypt.so.1
- libdl.so.2(GLIBC_2.1)
- libpthread.so.0(GLIBC_2.2)
- libc.so.6
- libfontconfig.so.1
- libpthread.so.0(GLIBC_2.3.2)

- libresolv.so.2()(64bit)
- libcrypt.so.1()(64bit)
- ibresolv.so.2(GLIBC_2.2.5)(64bit)

If you are using an Operating Systems not shipped with libstdc++.so.6, you need to install NX Client for Linux i386 package for earlier Linux versions. This NX Client software works on 64bit hardware as long as the Operating System offers support for 32bit applications. Please note that, in order to be compatible also with oldest Linux versions, it doesn't offer support for XFT libraries.

Libraries required on the local system in order to install NX Client for earlier Linux versions are:

- ld-linux.so.2
- libdl.so.2
- libpthread.so.0(GLIBC_2.1)
- libaudiofile.so.0
- libdl.so.2(GLIBC_2.0)
- libpthread.so.0(GLIBC_2.2)
- libcrypt.so.1

Double-click on the icon of the NX Client executable file you have downloaded from the NoMachine Web site: the NX Setup Wizard will take you through the installation.

Step 1

Select where to install NX Client and confirm by clicking on the Next button.

Step 2

The Setup Wizard will allow you to create the program shortcut in the Start Menu by default or in any folder of your choice.

To proceed, click on the Next button as usual.

Step 3

A further dialog will enable you to create an additional shortcut to the application on your desktop.

Confirm according to your personal preference.

Step 4

The final dialog will ask you to confirm the installation of NX Client on your machine.

Exit the installation

Double-click on the icon of the NX Client setup you have downloaded from the NoMachine Web site. The NX Setup Wizard will take you through the installation update.

Step 1

If you have already launched your NX Client, the NX Setup Wizard will give you the following message:

'NX Client for Windows detected that some programs are in use by Windows. The setup will not be able to replace these files. Do you want to kill the running programs?'

It refers mainly to the cygserver process whose functionalities are shared among all the running NX sessions. It is designed to be resident and run as a background service as suggested in the Cygwin Web site. Please proceed by clicking on Yes to continue the installation update.

Steps 2

The next dialog will allow you to choose which directory the client will be installed in. If you choose the same directory where your previous installation is placed, click on the Yes button in the dialog asking:

'The folder ..... already exists. Would you like to install to that folder anyway?'

To remove the NX Client installation, please run the Uninstall NX Client for Windows utility. If you have created the shortcut to the NX Client in the default Menu folder, select:

Start > Menu > Programs > NX Client For Windows and click on Uninstall NX Client for Windows

Otherwise, access the NX Client installation directory and double click on the unins000.exe executable file. It will give the following message:

'Are you sure you want to completely remove NX Client for Windows and all of its components?'..

The additional fonts are only needed when running very old Unix applications, requiring the use of client-side fonts. More recent Unix applications use fonts stored on the server, which are fully supported by NX.

The additional fonts packages, available at http://www.nomachine.com/download, are:

• nxfonts-75dpi.exe - Font Family 75 dpi
• nxfonts-100dpi.exe - Font Family 100 dpi.
• nxfonts-misc.exe - Font Family Misc
• nxfonts-others.exe - Font Family Others (encodings, type, util, speedo)

The following NX Client 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

Please note that NX Client for 32bit architecture for earlier Linux versions works correctly on 64bit hardware, for example with CPUs based on the AMD64 chipset reference design, as long as the Operating System offers support for 32bit applications.

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 nxclient-X.Y.Z-W.i386.rpm

Open an xterm terminal or similar, make a backup of your current NX Client 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 update the installation:

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

The rpm utility will fail if NX Server is installed. First, uninstall NX Server then proceed with the uninstall of the NX Client.

Open an xterm terminal or similar and uninstall the package:

# sudo rpm -e nxclient

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

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

Open an xterm terminal or similar, make a backup of your current NX Client 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 client package from the NoMachine Web site and install it:

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

The dpkg utility will fail if NX Server is installed. First, uninstall NX Server, then proceed with the uninstall of the NX Client package.

Open an xterm terminal or similar and run:

# sudo dpkg -r nxclient

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 nxclient-X.Y.Z-W.i386.tar.gz /usr

and extract the archive:

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

Open an xterm terminal or similar, make a backup of your current NX Client 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 and extract the archive:

# sudo tar xvzf nxclient-X.Y.Z-W.i386.tar.gz

This operation will remove both the NX Client and the NX Server installations if the server has been installed on the system.

Open an xterm terminal or similar and remove the installation directory:

# sudo rm -rf /usr/NX

Download the pkg.zip package and run the Finder to search for the downloaded package. Then, double-click on the icon of the package to uncompress the zip archive.

Open a terminal and remove everything from the old installation:

# sudo rm -rf /usr/NX 
# sudo rm -rf /Applications/NX*.app 

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

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

Open a terminal, make a backup of your current NX Client 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 NXclient

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

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

The pkgrm utility will fail if NX server is installed. Open a terminal, first uninstall NX Server and then proceed with the uninstall of NX Client:

# sudo pkgrm NXclient
