CUPS Printing Backend
The NX Client set-up procedure detected that your "IPP
CUPS" printing
backend doesn't allow printing from the NX session. In order
to have
printing support in your NX system, you need to set proper
permissions
on the IPP backend. Please execute:
chmod 755

Server keys
The initial login between client and server happens through
a DSA key
pair, i.e. a couple of specially generated cryptographic keys,
called
the private key and the public key, which allow you to establish
a
secure connection, by means of SSL encryption, between NX client and
NX
server.
The public part of the key-pair is provided during the
installation
of the server, while the private part of the key-pair is
distributed
together with the NX Client. This ensures that each NX client is
able
to authenticate to the server and to start the procedure for
autho-
rizing the user and negotiating the session.
If you want to create a virtual private network (VPN)
instead, you
need to generate a new DSA key-pair and distribute the private
part
of the key-pair to those NX clients you want authenticated to the
NX
server. More information on how to generate and distribute a new
DSA
key-pair is available at:
http://www.nomachine.com/ar/view.php?ar_id=AR01C00126
Creating Users
NX is configured to allow access from any system user, as
long as
valid credentials are given to the user for the SSH login. NX
pro-
vides an alternative authorization method, allowing system
admin-
istrators to determine which users are given access to the NX
fun-
ctionalities. This works by implementing a separation between
the
system password and the NX password, so that, for example, it
is
possible to forbid remote access to the system by any other
means
except via NX and use the NX tools to implement effective
accounting
of the system resources used by the user, or to share NX passwords
in
an external database.
To activate the NX user and password DBs, you will have to
edit the
NX server configuration file by hand or use the NX Server
Manager
Web tool available for download on the NoMachine Web site at:
http://www.nomachine.com/download-manager.php
Session Shadowing and Desktop Sharing
The session shadowing functionality allows you to share NX
sessions
running on the node. The desktop sharing functionality instead,
gives
access to the native display of the X server as if you were in
front
of the monitor. By default you can access sessions in interactive
mode
and upon authorization of the session owner. You can modify this
beha-
viour by tuning the server configuration according to your needs,
for
example by allowing access to sessions in view-only mode, or
connecting
to either a suspended session or the local display via the
Desktop
Manager login window.
Load Balancing
NX Advanced Server provides support for multi-node
capabilities and
load balancing. In its current implementation, NX server can
only
manage accounts on the host machine, so to grant access to the
node
running remotely, you will need to create the user account
directly
on the remote node host by issuing the NX node commands as root
user.
You will also need to add the NX Server public DSA Key to the node
to
allow this server to connect to the node running on the remote
host.

of your
NX system, please refer to the System Administrator's Guide

2. freenx 세팅
freenx는
기본적으로 22번 포트(SSH 포트)를 사용한다.
# vi /usr/NX/etc/server.cfg 로 설정을
수정한다.
#SSHDPort = "22" 를 주석을 푼뒤 저장한다.
그다음 #vi /etc/sysconfig/iptables 로 22번 포트를 열어준다.

RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
방화벽재기동
# /etc/rc.d/init.d/iptables restart
# netstat -ntlp 로 22번 포트가
열려있나 확인한다.
안열려 있을 경우 ssh와 nxserver을 restart 시킨다
정상적으로 확인이
될경우
ntsysv로 시작프로그램으로 등록해 매번 실행시키는 수고로움을 덜자

NoMachine NX Desktop on Ubuntu 12.04
Precise Pangolin ? No menus?
Posted on May 28, 2012 by

---------------------------------------------------------------------
NoMachine
NX is a perfect solution to connect to your remote Ubuntu desktop.
But ever
since Canonical introduced Unity, NoMachine doesn’t seem so perfect anymore:
client successfully connects to the NX server, but the menus never show up,
and there’s no Unity side bar.
Here’s what works in 12.04 Precise Pangolin:
On the remote machine open up this file:
/usr/NX/etc/node.cfg and edit it as a superuser:
sudo vim
/usr/NX/etc/node.cfg
Towards the end of the file, look for
CommandStartGnome and change it to
CommandStartGnome =
"/usr/bin/gnome-session --session=ubuntu-2d"
Save the file,
and Unity should now work in 2D mode the next time you connect and the menus
and the sidebar will show up.
