			=== 3 Get virtual machine accessable from the internet ===

			==== 3.1 Set up network bridge ====
			In virtualbox, tap the virtual machine in the list on the that you want to reach from the internet

			Press the yellow gear symbol Settings (top right)

			In the left menu, select Network. In Adapter 1 -> go to Attached to: and select "Bridged Adapter" In Name: it should say the same network interface as the host computer.

			Then press OK

			Now start the virtual machine by pressing -> start

			==== 3.2 Find the local IP address of the virtual machine ====
			Find the ip address of the virtual machine so we can expose it to the internet

			type in Konsole:

			<code>ip-a</code>

			Extract of what you get by running the command above:
			enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
			link/ether 08:00:27:53:e3:d1 brd ff:ff:ff:ff:ff:ff
			inet '''192.168.0.135'''/24 brd 192.168.0.255 scope global dynamic noprefixroute enp0s3
			Highlighted is the local ip address of the virtual machine.

			Note: Your IP address may be different

			==== 3.3 Open the port in the router ====
			In your router, visit the place where you open up ports. Where you do this on your router varies from manufacturer to manufacturer.

			On an ASUS GT-AC2900 router, it is done this way:

			Select WAN in the left menu -> Virtual Server / Port Forwarding -> scroll down and select "Add profile". Fill in the following:

			Protocol: TCP

			External Port: 8080

			Internal IP Address: 192.168.0.135

			NOTE. The IP address of the virtual machine may be different for you.

			Press OK

			Go to [https://whatismyip.com/ https://whatismyip.com] to find your external IP address

			Open a browser on the host, or on another computer and go to: http://<your external ip>:8080/openmrs/spa

			for example: http://79.161.82.18:8080/openmrs/spa

			If everything is done right now, you will get the login screen for OpenMRS

=== '''1.2 Install virtualbox 7.1 i Debian 12 bookworm''' ===

Put the repo, signature and install in one command, by copying and pasting into konsole:

 <code>sudo touch /etc/apt/sources.list.d/virtualbox.list && echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/oracle-virtualbox-2016.gpg] <nowiki>https://download.virtualbox.org/virtualbox/debian</nowiki> bookworm contrib' | sudo tee /etc/apt/sources.list.d/virtualbox.list && wget -O- <nowiki>https://www.virtualbox.org/download/oracle_vbox_2016.asc</nowiki> | sudo gpg --yes --output /usr/share/keyrings/oracle-virtualbox-2016.gpg --dearmor && sudo apt update && sudo apt install virtualbox-7.1</code>

virtualbox 7.1 is now installed in Debian 12



= 2 Install VBoxGuestAdditions in virtualbox =

VBoxGuestAdditions provides the following features:

* Host/Guest clock synchronization

* Seamless window support

* Shared folders

* Shared clipboard

* Mouse pointer improvements

* Improved video support



=== 2.1 On the Host Machine: Download VBoxGuestAdditions.iso ===

Dowload for the version you are running of Virtualbox. In the example we use VirtualBox7.1 as we installed in section 1. Therefore we download VBoxGuestAdditions_7.1.0.iso with wget to a folder on the host machine, for example:

 <code>wget <nowiki>https://download.virtualbox.org/virtualbox/7.1.0/VBoxGuestAdditions_7.1.0.iso</nowiki></code>



=== 2.2 Start up the relevant virtual machine (Guest) running Debian 12 ===



===== 2.2.1 Mount the iso inside the virtual Debian install =====

Press Devices -> Optical Drives -> Then press Chose a disk file and scroll to where you downloaded the iso file to, press the iso file



You will get a pop-up message in the bottom right corner:



Press «'''Mount and open»'''



===== 2.2.2 Open Terminal =====

Right-click in the window that pops up and press on '''"Open terminal here"'''



===== 2.2.3 Install kernel header and build tools =====

Install kernel header for running kernel and build tools and press enter -> enter the password and press enter again:

 <code>sudo apt install linux-headers-amd64 build-essential -y</code>



===== 2.2.4 Install the VBoxLinuxAdditions =====

Run the following command to install the virtualbox add-on and press enter:

 <code>sudo sh VBoxLinuxAdditions.run</code>

Enter the password of the user and press enter again if prompted.



===== 2.2.5 Log out and in or restart the virtual machine to complete installation =====

Log out and log in again or:



restart the virtual machine by pressing;



Start button at bottom left -> Exit ->  



Press '''OK''' or wait 30 seconds



===== 2.2.6  Enable biderectional clipboard =====

Once the virtual machine has restarted, in virtualbox press: Devices -> Shared Clipboard -> Bidrectional



Note: With Bidirectional, you can copy to and from the virtual machine 🙂
