Nomachine NX Libraries and freenx-server
unfortunately there are no up-to-date freenx-server/-libs Packages for Debian Etch available. I found the documentation for building the required lib’s either wrong, or incomplete - here is another try.
This rough guide should help to setup a basic FreeNX 0.73 Server.
Basic NX- and rudimental linux-building knowledge to track down compilation errors is expected.
First:
- You might save your nx .ssh directory with the authorized_keys and client.id_dsa.key from a previous Installation.
- Remove/Purge all NX packages and freenx. Mainly you can identify them with a
dpkg -l | grep nx, lynx doesnt count however
- Move /usr/NX out of the way.
Second:
- install some required packages:
apt-get install xdialog expect netcat libxcomposite1 libxdamage1 xutils xutils-dev build-essential - get the freenx-server files as Archive or svn:
# svn checkout http://svn.berlios.de/svnroot/repos/freenx/tags/freenx-server/FreeNX-0.7.3
enter the FreeNX directory and apply the gentoo-nomachine.diff - who knows where this misleading name comes from.
#patch -p0 < gentoo-nomachine.diffand install freenx-server with # make ; make install- get the NX sources and unpack them:
Goto http://www.nomachine.com/sources.php and download the following archives into your build folder and untar them. I choose /usr/local/src/nxlibs for this:-rw-r--r-- 1 root staff 1611890 2008-07-23 15:18 nxagent-3.2.0-10.tar.gz -rw-r--r-- 1 root staff 30679 2008-04-08 11:05 nxauth-3.2.0-1.tar.gz drwxr-xr-x 2 501 501 12288 2008-09-01 11:27 nxcomp -rw-r--r-- 1 root staff 532187 2008-05-22 13:35 nxcomp-3.2.0-7.tar.gz drwxr-xr-x 2 tim users 4096 2008-09-01 11:29 nxcompext -rw-r--r-- 1 root staff 90315 2008-04-08 11:05 nxcompext-3.2.0-1.tar.gz drwxr-xr-x 2 512 512 4096 2008-09-01 11:33 nxcompshad -rw-r--r-- 1 root staff 76668 2008-05-22 16:57 nxcompshad-3.2.0-3.tar.gz drwxr-xr-x 3 505 505 4096 2008-09-01 11:47 nxproxy -rw-r--r-- 1 root staff 82736 2008-04-08 11:05 nxproxy-3.2.0-1.tar.gz drwxrwxr-x 10 501 501 4096 2008-09-01 11:24 nx-X11 -rw-r--r-- 1 root staff 20215674 2008-06-23 14:42 nx-X11-3.2.0-2.tar.gz
- go inside nx-X11 and run
# make World. (with current multicore cpus “-j 4″ will speed up the buildprocess)
If you get an error, read them carefully and install the required “-dev” Package. To name them all is beyond this howto, but to have a basic build environmet install build-essential (Debian).
To get most (or even all) required -dev packages install libqt3-mt-dev (QT -dev Pack of Debian). Note: libqt3-mt-dev itself is not needed for NX but its dependecies will install many other needed packages. - afterwards go inside nxproxy and run
# ./configure && make - there is no make install for the NX libs and bins, so we do it by hand:
cp -a nx-X11/lib/X11/libX11.so* /usr/NX/lib cp -a nx-X11/lib/Xext/libXext.so* /usr/NX/lib cp -a nx-X11/lib/Xrender/libXrender.so* /usr/NX/lib cp -a nxcomp/libXcomp.so* /usr/NX/lib cp -a nxcompext/libXcompext.so* /usr/NX/lib cp -a nxcompshad/libXcompshad.so* /usr/NX/lib cp -a nx-X11/programs/Xserver/nxagent /usr/NX/bin cp -a nxproxy/nxproxy /usr/NX/bin
I prefer to have some links in /usr/bin:
cd /usr/bin ln -sf /usr/NX/bin/nxloadconfig . ln -sf /usr/NX/bin/nxsetup . ln -sf /usr/NX/bin/nxserver .
Third:
- /usr/NX/bin/nxsetup –install
- cp /usr/NX/etc/node.conf.sample /usr/NX/etc/node.conf
- migrate your keys to /usr/NX/home/nx/.ssh
easy!

Hi, thanks for this guide, I followed one by one steps listed, and I think that nxserver is running, but I dont understand the last step “migrate your keys to /usr/NX/home/nx/.ssh”, as a result the client says (in windows) “Authentication failed for the user”.
What I have to do in that step?
Thanks again.

Hello gonzo!
the last step is only intended for users that want to migrate the key from a previous installation.
“Auth failed f. t. user” can have several reasons. Try with the nomachine default key and enable LOG_LEVEL 7 in node conf to get more informations.
Greetings,
Tim

I would do following:
delete /usr/NX/home/nx/.ssh/ and run the nxsetup script again
and
try setting this in node.conf:
ENABLE_SSH_AUTHENTICATION=”1″
ENABLE_USER_DB=”0″
report back!

Hi, the report of /usr/NX/bin/nxsetup –install is:
# /usr/NX/bin/nxsetup –install
——> It is recommended that you use the NoMachine key for
easier setup. If you answer “y”, FreeNX creates a custom
KeyPair and expects you to setup your clients manually.
“N” is default and uses the NoMachine key for installation.
Do you want to use your own custom KeyPair? [y/N] N

Please correct the configuration file.
I think that last error is the problem, but I don’t know how to resolve it.
Thank for help me.

I deleted /usr/NX/home/nx/.ssh/ and then I did the setup, and happens the same
June 3rd, 2008 at 18:39
set SESSION_LOG_CLEAN=0 in node.conf
relogin and investigate the files under /home/you/.nx for error message.
I think the Error from nxsetup can be ignored.

Now is running!!
what was the problem?
Thanks a lot.

Hi,
Very useful article. I need just an information : In effect, I have an error as soon as I must doing the “make world”. And you say, at this subject :
“# make World. (with current multicore cpus “-j 4″ will speed up the buildprocess)
If you get an error, read them carefully and install the required “-dev†Package
”
It’s perfect, but… could you say mefrom what “-dev Package” do you speak, please? lol, there are many.
Thanks at advance.

Hello Chris,
sorry for the delay. I have added a little help concerning your question.

hi,
All is working for me except RDP session,
When i open a windows session : i have error : “can’t open /usr/NX/bin/nxdesktop_helper …”
I fix it by replacing nxdesktop_helper provided en freenx 0.73 by 0.72 version
Now, it’s running
