Remote session to a lab computer using NoMachine

Remote working means logging on to a CDA lab or edit room computer from your computer at home. NoMachine is a remote desktop solution that is superior to Apple’s built-in screen sharing and, most importantly, you will have audio.

You do not need a powerful computer for remote working. Your Mac OS needs to be OS X 10.7 or later to use NoMachine. But a high speed internet connection (15Mbit/s download and 10Mbit/s upload) is required.

This guide takes into account that you already booked the computer on which you want to connect to. If not please follow this guide : How to reserve a lab or edit suite computer for remote sessions

In order to connect remotely to an edit suite or  lab computer, you’ll need to connect to Concordia’s network through VPN. How to connect to Concordia’s VPN

Download the NoMachine client from : https://www.nomachine.com

To install it on your computer, simply open the downloaded DMG file and run the PKG installer. This will require admin rights to install.

If you are using a Concordia owned client computer, we will make the client available as an optional installation via Managed Software Center.

Once installed, simply double click the nxs shortcut downloaded previously.

This is the shortcut that is provided by the calendar reservation system. This shortcut only works once your booking time has started.

You will be prompted to validate the authenticity of the remote host, click yes.

You may see the following screen with both the username and password pre-populated, simply click OK.

NoMachine will then ask you a multitude of questions regarding the windowing, shorcut keys, sound preferences etc. You can customize the display quality and audio controls later.

There are details further on in this page.

Sign in with your CDA credentials.

Once signed in to the computer, wait 30 seconds or so for the desktop to be refreshed and present you with the customized lab computer environment. Please read the desktop picture notice.

You should adjust the display and audio settings once you are logged into your account.

Go into the menu settings by selecting the top right hand corner of the remote desktop window. You should see the corner peel back.

Go into Audio Settings.

You can change the volume of the audio here and select Change Settings.

Change the audio settings to look like this. The Enable streaming should be check marked. Make sure that Mute audio on server is NOT checkmarked.

You can change the audio quality as you wish. I recommend using the maximum audio quality.

Then say Done and go back to the Display menu settings.

Don’t expect miracles from remote working.  The image and audio is being compressed in real time. There will be dropped frames on video and audio will be out of sync with video.

Here are the optimal setting for working remotely with video and audio through a standard high speed 15/10 internet connection.  Copy exactly what you see here.

The resolution may vary depending on the computer you are accessing. See the next picture.

On the computers with 4K displays choose the following settings.

You can adjust these settings at any time to vary the playback quality.

If you have issues hearing audio in any application, go the application’s audio hardware settings and make sure the NoMachine Audio Adapter is the output device. It should be the default device.

Audio is stereo only. For obvious reasons, the microphone input on the computer will not work, or it will work if you want to record the sound of the computer lab!

Any files that you work on should be transferred to the CDA computer desktop or documents folder. Before your remote reservation begins, transfer your files to your home folder on the CDA server goliath.

Transferring GBs can take some time. Here is how to connect our servers using FTP: FTP Connect

Your home folder is mounted automatically on the desktop when you log in remotely and the files can be copied to the desktop. You have a 10 GB space limit on your home folder. If you need more space please contact the CDA.

To copy small files, simply drag from your desktop at home on to the NoMachine remote desktop window.

Once your session is finished, please log out of your session from the Apple menu.
