NinjaRMM sucks. Here’s how to run its terrible little connection tool on a proper OS.

First, install a user-agent spoofer in your preferred browser - Ninja’s site won’t even show the connection button without this nowadays. Set it to Windows something.

Here are links to a user agent spoofer-manager thing:

• for Chrome
• for Firefox

Here are links to the most recent user agent strings:

• for Edge
• for Chrome
• for Firefox

You’re after the Windows versions. In my case, I set my user agent string to “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/135.0.0.0 Safari/537.36 Edg/135.0.3179.98”.

You can confirm that everything is working with the wonderful whatismybrowser.com.

You’ll need Wine. If you don’t have Wine, you can typically install it with dnf install wine or apt install wine.

To download the NinjaRemote installer, navigate to a device in Ninja. If you’ve done things correctly, you’ll see the Ninja Remote ‘connect’ button. Click the button. Wait for the connection to time out, and download the 32-bit version of NinjaRemote from the pop-up.

Open up a terminal. To install NinjaRemote, run the executable with Wine, then click through the applet:

$ wine ~/Downloads/ncinstaller-x86.exe

Create a .desktop file for Ninja Remote:

$ cat <<EOT >> ~/.local/share/applications/ninja-remote.desktop
[Desktop Entry]
Name=Ninja Remote
Exec=bash -c 'wine "/home/liam/.wine/drive_c/users/liam/AppData/Roaming/NinjaRemote/ncplayer.exe" "%u"'
Type=Application
Terminal=false
MimeType=x-scheme-handler/ninjarmm
EOT

Register the .desktop file with your shell:

$ xdg-desktop-menu install ~/.local/share/applications/ninja-remote.desktop

Register the .desktop file as a handler for NinjaRMM custom protocol URLs:

$ xdg-mime default ninja-remote.desktop x-scheme-handler/ninjarmm

All in one:

wine ~/Downloads/ncinstaller-x86.exe

cat <<EOT >> ~/.local/share/applications/ninja-remote.desktop
[Desktop Entry]
Name=Ninja Remote
Exec=bash -c 'wine "/home/liam/.wine/drive_c/users/liam/AppData/Roaming/NinjaRemote/ncplayer.exe" "%u"'
Type=Application
Terminal=false
MimeType=x-scheme-handler/ninjarmm
EOT

xdg-desktop-menu install ~/.local/share/applications/ninja-remote.desktop

xdg-mime default ninja-remote.desktop x-scheme-handler/ninjarmm

You should now be able to Ninja Remote to PCs from your Linux box as you normally would on a Windows PC.
