When installing NoMachine NX 2.x on Ubuntu Linux, the following information will be helpful.

Ubuntu Pre-requisites for NX

Obtain ROOT privileges in a terminal (through sudo or sudo su - ).
The NX applications require the following library:

      libstdc++-libc6.2-2.so.3

                available in the Ubuntu package

                libstdc++2.10-glibc2.2"

               This package (libstdc+2.10-glibc2.2) is not available by default with
   Ubuntu 64 versions, You will need to install this package by
   downloading it from the following location:
             http://packages.ubuntu.com/dapper/libs/libstdc++2.10-glibc2.2

     Click the i386 link to select a download mirror. Download and save the
   *.deb package to your hard drive.

               Issue the following command:

               dpkg -i --force-architecture libstdc++2.10-glibc2.2

The NX applications require the following package for Ubuntu:

NX Client Installation

Root privileges are required to install the NX Client software. If you don't have access to your machine as root user, please contact your System Administrator.

Open an xterm terminal or similar, move to the directory where you have placed the NX Client 2.x DEB package.
Install it using the dpkg utility:

dpkg -i --force-architecture nxclient_X.Y.Z-W_i386.deb

              dpkg -i --force-architecture nxnode_X.Y.Z-W_i386.deb

      On a base Ubuntu 6.06 install, you will get an error regarding CUPS not being installed. You will need to install CUPS and configure NX with appropriate path with the command shown. As this is a how-to for basic NX installation, the installation of CUPS will not be covered here.

Installing the Server

      Root privileges are required to install the NX Node software. If you don't have access to your machine as root user, please contact your System Administrator.

                          /usr/NX/bin/nxserver --status

      The output should look similar to the following:

      NX > 900 Connecting to server..
      NX > 110 NX Server is running.
      NX > 999 Bye.

      Congratulations! NoMachine NX Client, Node and Server 2.x are now installed and working on Ubuntu 6.06 64-bit.

NX Software Activation

      During the 30 day trial installation, you do not have to do the following as a 30 day license key is installed with the trial packages.

      After you purchase a NoMachine NX Subscription, you will receive a key.tar.gz file with your purchased license key. You will need to follow the instructions below to activate your software.

Log in as root on the server which hosts the NX Server installation.
Download the attachment of this email to a file named: key.tar.gz
Put it into the '/usr/NX/etc' directory.
From a root shell prompt execute the commands reported below to extract the license key file otherwise skip to the next point:

                          cd /usr/NX/etc
                          gzip -d key.tar.gz
                          tar -xvf key.tar
                          rm key.tar

From a root shell prompt execute the commands reported below to
set the proper permissions attributes and the correct owner on
the license key file:

chmod 0400 /usr/NX/etc/server.lic
chown nx:root /usr/NX/etc/server.lic

To check if the new license file was correcly installed issue the following command from a root shell prompt:

                          /usr/NX/bin/nxserver --version

        The output should look similar to the following:

              NX > 900 Connecting to server..
        NX > 110 NX Server is running.
              NX > 999 Bye.

      Congratulations! NoMachine NX Client, Node and Server 2.0 are now installed and working on Ubuntu 6.06 64-bit.
