After:
nxserver --keygen

I have:

/usr/NX/share/keys
total 6
-rw-r--r--. 1 root root 668 Feb 26 00:01 default.id_dsa.key
-rw-r--r--. 1 root root 668 Feb 19 14:40 default.id_dsa.key.backup
-rw-r--r--. 1 root root 668 May 28  2007 server.id_dsa.key


and

/usr/NX/etc/keys/
total 4
-rw-r--r--. 1 root root 603 Dec 19  2010 node.localhost.id_dsa.pub
-rw-------. 1 nx   root 672 Dec 19  2010 node.localhost.id_dsa


I do not understand:

then just go and recopy the key from inside the client .key file in the 
shared keys directory and paste it in your NX CLIENT and the connection 
will then complete successfully.


On the server
I deleted /usr/NX/share/keys/default.id_dsa.key

and copy the key:
/usr/NX/share/keys/default.id_dsa.key
of the client on the server.
I also tried do copy in
/usr/NX/etc/keys/

nxserver --restart

But still does not work.
