NoMachine is a remote desktop tool. Just like VNC. So what is the difference between NoMachine with the other? The most important factor is speed. The NX protocol provides near local speed responsiveness over high latency and low bandwidth links. So it feels like you were directly in front of your computer.
NoMachine version 4.0 has many key features. When you connected to NoMachine-enabled computer, you can work with any content such as documents, music, videos, as if you were in front of your computer. You can also have the same desktop environment from where ever you are connected.

When you run NoMachine for the first time, there is a wizard to help you configure your first connection. Here are the steps:
Create a Connection
You will be asked to create a connection. It will include Name (connection), Host (destination), Protocol and Port. By default, NX protocol will work on port 4000. But you can switch to SSH protocol if you want.
Then a confirmation screen will appear. You can press Connect button to run the connection.
Verify Host Authenticity
When you run NoMachine for the first time, NoMachine will ask you to verify the destination host authenticity.
Provide User Credential to Login
Now you will be asked to provide user credential to login to the destination host. If the destination host allows Guest login, you may click “Login as a guest user” parameter. You can save the user password in the configuration file if you want. Just click “Save this password in the configuration file parameter”. Next time, you will not need to enter password again to connect.
Connecting to Destination Host
After providing user credential, NX will show you a first guide to use NoMachine. There are a lot of icons that you can click on it. It covers the screen, input, devices, display, audio, mic, recording and connection.
After you finish with the guide, then you will see your destination host appear with full desktop capacity. On the destination host, a notification will show if a user is connected or disconnected.
Although NoMachine is basically free, Free Edition has a limit of 2 concurrent connections only. If you need to have more concurrent connections, you may use the Enterprise Edition. And before you choose what solution you need, you should look at NoMachine feature comparison.
