Despues de instalar nxmachine no todo ha sido coser y cantar hemos tenido algunos problemillas con faciles soluciones
Las nuevas versiones de NX solo permiten la conexion si tienes importada la clave server del RSA para ello debemos generarla.
Sacamos nuestra version de Nx
nxserver-3.5.0-9.i386
nxclient-3.5.0-7.i386
nxnode-3.5.0-7.i386
[root@Syswoody ~]# rpm -qa |grep nxnxserver-3.5.0-9.i386nxclient-3.5.0-7.i386nxnode-3.5.0-7.i386
Ahora sacamos el listado de todos los paquetes con rpm -qil
[root@Syswoody ~]# rpm -qil nxserver-3.5.0-9.i386

Summary : NX Free Edition
Description :
NoMachine NX is a fast and scalable terminal server system based on the
X11 protocol. NX lets you work fluently even across slow links like modems
and provides a full set of administration tools that make it a complete
desktop virtualization solution for your organization.
This package contains the NX Server software.
Baseline:
nxnode: 3.5.0-7
nxstat: 3.5.0-1
This package requires the installation of a compatible version of the NX
client and NX node software.
/usr/NX
/usr/NX/bin
/usr/NX/bin/nxserver
Una vez indentificado generamos nuestra clave RSA para lo cual recibiremos un error
[root@Syswoody .ssh]# /usr/NX/scripts/setup/nxserver --keygen
NX> 704 Starting: server-keygen operation at: lun jul 25 09:52:28 2011.
NX> 704 Generating new ssh-keys. Please wait.
NX> 704 ERROR: Cannot generate SSH keys for NX Server authentication.
NX> 704 Error is: open /usr/NX/home/nx/.ssh/new.id_dsa failed: Permission denied.
Saving the key failed: /usr/NX/home/nx/.ssh/new.id_dsa..
Debemos deshabiltar nuestro SeLinux para poder generar nuestra clave
[root@Syswoody .ssh]# setenforce 0
Lo intentamos de nuevo y OK
[root@Syswoody .ssh]# /usr/NX/scripts/setup/nxserver --keygen
NX> 704 Starting: server-keygen operation at: lun jul 25 09:53:26 2011.
NX> 704 Generating new ssh-keys. Please wait.
NX> 704 Keys generated correctly. Backing up files.
NX> 704 Back up of keys made. Updating files.
NX> 704 Keys updated. NX clients should now use key:
NX> 704 /usr/NX/share/keys/default.id_dsa.key
NX> 704 to get connected to this NX server.
Ya tenemos la clave le hago un cat sobre el fichero /usr/NX/share/keys/default.id_dsa.key copio el contenido y lo añado dentro del campo key de las opciones de nomachine en el cliente.
Ahora al lanzar la conexion falla y me manda al messages.log donde nos muestra algo como esto.
