These instructions were tested on Fedora 35 with RemoteBox 3.0, other configurations may vary. They describe installing the RemoteBox client and assume you have root privileges to perform the install. In order to connect from RemoteBox, VirtualBox will need to be installed and configured on the server and if necessary appropriate firewall ports will need to be opened.

RemoteBox is available in the official Fedora repositories which may be sufficient for your needs, although the version may differ from the latest. It can be installed as follows:

dnf install RemoteBox freerdp tigervnc

Ensure the required dependencies are installed as follows:

dnf install perl-Gtk3 perl-SOAP-Lite freerdp tigervnc xdg-utils

To launch RemoteBox, unpack the RemoteBox tarball and run the 'remotebox' executable.
