NX test on polarhome

[zoli]

Hello,

we are testing the following product:

NoMachine NX is an enterprise-class solution for secure remote access, desktop virtualization, and hosted desktop deployment built around the self-designed and self-developed NX suite of components. Thanks to its outstanding compression, session resilience and resource management
and its integration with the powerful audio, printing and resource sharing capabilities of the Unix world, NX makes it possible to run any graphical application on any operating system across any network connection. Via
NX accessing remote desktops, servers and applications, whatever their location, is just as fast, easy and secure as if you were sitting in front of them. Together with easy-to-use management, deployment, and monitoring tools, NoMachine NX makes it possible to transform any traditional desktop computing environment into a centrally managed, globally accessible, virtual desktop infrastructure.

currently we are running on redhat, ubuntu and solaris the NX free edition:

A complete solution for remote access to your Unix workstation. It allows 2 concurrent users to connect no matter what their location is, and share the desktop. NX Free Edition is incredibly easy to install and run, leverages the competence and quality of the company that makes NX and, most importantly, is free forever.

knowledge-base addition - just to save some time for other admins.

ubuntu and solaris worked out of the box without any special configuration needed.

rpm packages on redhat (fedora 9) needed some minor tuning.

NX uses public key authentication for with nx user stored in /usr/NX/home/nx/.ssh/authorized_keys2 per default.

As fedora default in /etc/ssh/sshd_config is:

Code: Select all

PubkeyAuthentication yes
AuthorizedKeysFile      .ssh/authorized_keys

nx user authentication will fail, because the AuthorizedKeysFile is not found.

Simple solution is to rename the authorized_keys file:

Code: Select all

root@redhat~# mv /usr/NX/home/nx/.ssh/authorized_keys2 /usr/NX/home/nx/.ssh/authorized_keys

Test the result with

Code: Select all

root@redhat~# /usr/NX/bin/nxserver --status
NX> 900 Connecting to server ...
NX> 110 NX Server is running.
NX> 999 Bye.


It does not work on debian, because the openssl is too old.
1. requires libcrypto.so.0.9.8 - debian has libcrypto.so.0.9.6
2. even with dirty fix with the library the error is:
.

Code: Select all

OpenSSL version mismatch. Built against 90805f, you have 9060df

Setup: use GNOME session for redhat and ubuntu and CDE for solaris.
