Getting Started with NoMachine

Start your journey to the next level of network computing

NoMachine enables secure access to remote computers over the Internet and on LAN, wherever those computers are. Free for personal use, NoMachine can be used to access your own desktop, to provide remote assistance on someone else's computer and facilitate remote collaboration. There are two ways you can connect to your computer using NoMachine: by using IP address of the machine you want to connect to (local or public-facing), or alternatively, by using NoMachine Network. If you want to connect using your target machine's IP address, stay on this page and continue reading below. If, on the other hand, you want to reach a machine that doesn't have a public IP address or is behind a firewall or NAT, see the dedicated tutorial for NoMachine Network, the new subscription service for all NoMachine users. It can be activated with any NoMachine server product, including the free edition, to make accessing your NoMachine-enabled computer and sharing your desktop over the Internet as straightforward as possible whilst keeping the connection and your computer secure.

Install NoMachine on the first computer

The instructions below are for connecting to a computer that is on the same local network (LAN) as you.
Download the NoMachine package for your operating system to the computer that you want to control remotely.
After completing the download, launch the installer.
Accept the license agreement and click Next and wait while Setup completes the installation.
To remotely connect to your Mac or PC you need a system user account for that computer (username and password). You also need to know its private IP address which is assigned to your specific device within your local network. If you want to connecting using your computer’s public IP address, click here. There are two ways you can check your computer's IP address in NoMachine. (i) Open NoMachine from the programs or applications menu. A Welcome panel will publish the local IP address of the computer on which you have installed the software (Fig. 1). Or (ii) click on the !M icon (the NoMachine Monitor) which is visible in the computer's system tray. Click on 'Server Status' (Fig. 2).
Take note of this IP address. You will need it in the next phase when you are ready to connect to this computer.
You can now close the NoMachine application.

Fig. 2 - The IP address can also be checked in Settings > Status accessible from the NoMachine monitor (!M) in the system tray

Install NoMachine on the second machine

Now go to the computer or device that you want to connect from.
Download and install NoMachine per the steps above.

Start your first NoMachine connection

Open NoMachine from the Programs/Applications menu on the device you want to connect from. Click 'OK' to go past the Welcome panels. The next panel is the 'Machines' panel (Fig. 3).
From 'Machines' you can start a new connection. NoMachine desktops which are advertized on your same local network and any connections which you create appear in this panel.
Insert the IP address in the 'Search machines' field and click 'Connect'. The connection will start and you can proceed to the section Login to the remote computer.
Alternatively, if you prefer, you can click 'Add' to create and configure the connection (Fig. 4).
In 'Add', you can assign a connection name for identification, in our example it's 'Testdrive'.
Insert the IP address you noted down earlier in the field 'Host' (Fig. 4).
The default settings of NoMachine server Port and Protocol, 4000 and NX respectively, are suitable for the majority of set ups.

If you’re an advanced NoMachine user and need to connect with a private key, smartcard authentication or other authentication means, this can be changed in Configuration.
Click 'Connect' to start the connection. Or you can click the back arrow to go back to the Machines panel. From the Machines panel, double click to start the connection (Fig. 5).

Connect with NoMachine to a computer over the Internet using its public IP address

Install NoMachine on the first and second computer as you did before.
To connect to your computer over the Internet over IP, you need a system user account on the remote computer and the PC's public-facing IP address.
You also need to enable NoMachine's automatic UPnP/NAT-PMP port-mapping. Go to Server settings > Ports > Select the NX service, and click on 'Configure'. Make sure the box 'Use UPnP to map the port...' is enabled and select 'Start mode' as automatic (Fig. 8).

Go back to 'Server status' to get the public-facing IP address.
NoMachine displays the computer’s public address like this: nx://151.1.192.128:29382. Take note of this network address. If a port number is not displayed next to the external IP, NoMachine has detected that you don't need it in the next phase.
If your computer's public IP is not displayed, it is likely you'll need to manually configure your router, so that the NoMachine server can be reached over the Internet. Alternatively, you can use NoMachine Network. This removes the need for knowing the public-facing IP address of your computer. See the tutorial here about how to get started with NoMachine Network.

Remotely connect to one computer from the other

Open NoMachine on the device you want to connect from.
Insert the IP address in the 'Search machines' field and click 'Connect'.
Or click 'Add' to create and configure a new connection.
You can insert the public IP address and port information, which you noted down earlier, in the field 'Host' and 'Port' (Fig. 11).

Fig. 11 - Insert the IP address in Search and click connect

Insert the credentials for your system account on the remote host in the login dialog (Fig. 6).
Click 'Login'.
You are connected! Your remote desktop is now at your fingertips.
