Third Maintenance Release of the NX 3.2.0 Node Packages

2008-06-25  by: Silvia Regis
ROME, Italy, June 25, 2008 - NoMachine releases the third maintenance release of NX Node 3.2.0. The new packages provide updated versions of the nx-X11 and nxagent components including patches which solve the issues reported by X.Org security advisory, June 11th, 2008:

http://lists.freedesktop.org/archives/xorg/2008-June/036026.html

Although in NX these vulnerabilities cannot lead to privilege escalation since the X11 agent never runs as root, we strongly advise all users to upgrade their NX Node packages to the latest version.

Upgrade

Upgrade instructions for Linux and Solaris SPARC platforms use the sudo utility. If you don't have it installed, log on as superuser ("root") and run the commands without sudo.

It is highly recommended you disable access to new NX sessions and terminate all running sessions before proceeding with the upgrade of the node. To disable access to new NX sessions and terminate all the running sessions, open an xterm or similar and run the following commands:

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

After the upgrade procedure is completed, restart NX server by running:

# sudo /usr/NX/bin/nxserver --start
 
RPM version for Linux
  • Download the RPMs
  • Change your working directory to the location where you saved the package and upgrade the node installation by running from a console:
    # sudo rpm -Uvh nxnode-3.2.0-xy.i386.rpm
DEB version for Linux
  • Download the DEBs
  • Change your working directory to the location where you saved the package and upgrade the node installation by running from a console:
    # sudo dpkg -i nxnode_3.2.0-xy_i386.deb
TAR.GZ version for Linux
  • Download the TAR.GZs in the /usr directory
  • Change your working directory to the location where you saved the package and uncompress it by running from a console:
    # cd /usr    
    # sudo tar zxvf nxnode-3.2.0-xy.i386.tar.gz
  • Run the setup script for updating the NX Node software:
    # sudo /usr/NX/bin/nxnode --update
SPARC.GZ version for Solaris
  • Download the SPARC.GZs
  • Change your working directory to the location where you saved the package and install it by running from a console:    
    # sudo pkgrm NXnode
    # sudo gunzip nxnode-3.2.0-xy.sparc.gz
    # sudo pkgadd -d nxnode-3.2.0-xy.sparc

Technology Brief
Data encryption and security

NX security is guaranteed at every layer involved in the communication process. NX uses SSH public-key encryption and 128 bit volatile random cookie generation.

Multimedia support

NX transparently tunnels Linux multimedia channels. Not only does NX play KDE and Gnome system sounds, but you can listen to MP3s played on the server and local workstation simultaneously.

Unified support for all major remote desktop protocols

Thanks to its outstanding compression performances, NX is able to deliver X, RDP and RFB remote sessions using the same client. This is achieved by translating "foreign" protocols into X-Window, the native protocol of NX.
