This seems to be a firewall issue. Please check your firewall settings and allow connections for NoMachine’s Network Service nxd, which listens by default on port 4000 (more about ports here: https://www.nomachine.com/AR01L00770).

Please check that the hostname you are using is correct. This error means that the IP address you are trying to connect to is not reachable.

Just a quick note on the fly. NoMachine 5 is now available. Check out the announcement here: https://www.nomachine.com/SU07M00100&sn=

[Britgirl]

Since we are about to go live with NoMachine 5 (a matter of minutes), why don’t you try this and see if the issue continues. We aren’t aware of on/off problems and disappearing screens, so it has to be investigated further. If it does, submit the logs as recommended.

Are you able to send us the full set of logs? Send them to forum[at]nomachine[dot]com. Please consult the instructions here to learn how to enable and locate them: https://www.nomachine.com/DT04M00076. Make sure you reference your topic in the email or subject.

The free NoMachine package is for access to the physical desktop as I already mentioned. So yes, it’s like VNC for the sake of a simple comparison. The products that are oriented to professionals and organizations provide the functionality (virtual Linux desktop sessions) that you are requesting. To clarify better what you can and can’t do with the free NoMachine product, please take a look at the following FAQ (-https://www.nomachine.com/faq):

What is the difference between physical desktop and virtual desktop?

Differences between NoMachine for Linux and NoMachine Workstation for Linux
https://www.nomachine.com/AR10K00702

If you’re looking for Linux terminal server functionality, or in the past you were using NX Free Edition, you need to use the Workstation. The download URL is linked directly from the URL I provided in my earlier post.

Any questions and issues concerning NX 3.5.0 must be directed to the appropriate website channel. In this case, if you’re a customer with a valid subscription, that’s the customer area. If you are using a free product or an expired subscription, please go to the footer of the website, click Contact Us and select General Enquiries.

The forums are entirely dedicated to NoMachine 4 and later. I recommend you try Workstation from the Terminal Server range with version 4 client (Enterprise Client or the free NoMachine package). If your problem persists, we can deal with the investigation appropriately as Graywolf mentioned.

We’re just concluding the last phase of testing, so not long now 🙂  The windows domain problem you mention is no longer an issue in version 5.

[Britgirl]

What you probably need is the Workstation for Linux. It’s in the Terminal Server range: https://www.nomachine.com/product&p=NoMachine%20Workstation

This will allow you to run your own personal Linux desktop and won’t be visible to others (on the monitor). NoMachine (free) is for connecting to the physical display. With version 5 which is being finalized as I write this it will be possible to blank the screen so passers-by don’t see what’s happening if there is a monitor attached. This might be an option to you if the Workstation isn’t.

[Britgirl]

can I ask whether NoMachine should add an “Other…” option to Yosemite’s login page?

We’re checking this on the latest version of NoMachine 5.

This is really a question specific to your environment and is better dealt with via our traditional support channels since there is sensitive data being asked for. This will be closed.

[Britgirl]

You can compare the Workstation and free NoMachine package for yourself 😉 https://www.nomachine.com/AR10K00702

It totally depends on what you want to do. Access to the physical desktop? Or access to a virtual Linux desktop and run up to 4 of these virtual instances? Do you need SSH built in? These are all choices you have to make. Subscriptions control the server software, clients don’t require subscriptions, so choose between NoMachine (server and client together) or the Enterprise Client.

Read our article on encryption: https://www.nomachine.com/AR10K00705

Encryption in the NX protocol is implemented using OpenSSL TLS/SSL.  Since version 4.1 it uses ‘ECDHE-RSA-AES128-GCM-SHA256’ as default cipher suite. ‘ECDHE-RSA-AES128-GCM-SHA256’ is an AES (Advanced Encryption Standard) block cipher with 128 bits key in GCM (Galois/Counter Mode). RC4 is used as backward compatibility when connecting from or to version 4.0.”

Btw, you can still tunnel NX over an SSH connection using the free version. You will need to set up SSH appropriately first on the client and server, then connect as per our instructions here: https://www.nomachine.com/AR10K00728

Thanks for taking the time to report your findings. We’ll be taking a closer look to see what’s going on.
