Remote Desktop software is often used in Linux. I have been using Xmanager and VNC. Today we see a new software: NoMachine. NoMachine NX is a fast Terminal Server and virtual desktop software based on X11 protocol. It is said that the speed is faster than VNC, and can even run in a 10 k bandwidth environment. And the picture is clearer than that of VNC.
NoMachine official website address: http://www.nomachine.com/
To use NoMachine, you must configure the server and client.
I. Server
The server needs to install three packages:
Nxserver-3.4.0-12.i386.rpm
Nxnode-3.4.0-11.i386.rpm
Nxclient-3.4.0-7.i386.rpm
Linux 32bit:
Http://www.nomachine.com/download-package.php? Prod_Id = 1, 2068
The following is a usage description on the NoMachine web page:
1. Download the RPMs
2. Change your working directory to the location where you saved the package and install it by running from a console:
# Sudo rpm-I nxclient-3.4.0-7.x86_64.rpm
# Sudo rpm-I nxnode-3.4.0-14.x86_64.rpm
# Sudo rpm-I nxserver-3.4.0-14.x86_64.rpm |
| If you don't have the sudo utility installed, log on as superuser ("root") and run the commands without sudo. |
| Note: click here for detailed instructions on how to install the NX Client, NX Node and NX Server packages. the NX service can be controlled by the command/usr/NX/bin/nxserver -- status | -- start | -- stop | -- restart. additional commands are available to configure the server. try/usr/NX/bin/nxserver -- help for more information. please, don't forget to download and read the NX Server Administrator's Guide available here. |

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/usr/lib/cups/backend/ipp

Ii. Client
Download Windows client:
Http://www.nomachine.com/download-client-windows.php
After installation, connect to the server.
After running, check the Configuration:
Here we need to enter the Host and remote desktop type. Currently, KDE and GNOME are basically used. If only one is installed in Linux, select the correct one.
There is also a network type.
Connected image:
There are two points to note:
1. the root user cannot be used for connection.
2. If you encounter any problems, check the environment variables:
To launch a desktop session, KDE or GNOME, the corresponding
Commands, either startkde or gnome-session must be set in the PATH.
If the command is not available in the PATH, an error message like:
"Cannot run 'startkde'. Please check that the requested application is in
The system PATH and that you have the rights to execute it ."
The NoMachine official website describes this error:
Http://www.nomachine.com/ar/view.php? Ar_id = AR06D00398
3. Modify the NoMachine Port
NoMachine and SSH use the same channel. Therefore, if the SSH port is modified, the NoMachine port must also be modified.
Two configuration files for NoMachine Port:
File 1:/usr/NX/etc/server. cfg
Modify the following two parameters:
SSHDPort = "222"
ServerName = "ds-nb-dbserver"
-- This is from the/etc/hosts file.
File 2:/usr/NX/etc/node. cfg
Modify the following three parameters:
NodeName = "ds-nb-dbserver"
SSHDPort = "222"
SSHDAuthPort = "222"
SSH port configuration file:/etc/ssh/sshd_config
The modified port must be consistent with NoMachine:
Port 222
Remember to add the port in the firewall:
Linux iptables Firewall adds and deletes ports
Http://www.bkjia.com/Article/201202/119414.html
Restart SSH and Port:
[Root @ ds-nb-dbserver Linux32bitServer] #/usr/NX/bin/nxserver -- stop
NX & gt; 123 Service stopped.
NX> 153 Stopping NX server monitor.
NX> 153 NX server monitor alreadystopped.
