6.1.4 Using Pre-Built Virtual Machine Images

When using this option, you can use a ready-made DGT node image that is available for download onto your computer. You can immediately use the node on your equipment. The following images are available for download:

#	Virtual Machine Image	Description	MD5 Checksum	Size
1	VirtualBox Matagami Core 2022	VirtualBox VM image running Ubuntu 20.02 with Docker 20.10.2 deployed and DGT Matagami Core installed (no tokenization); no dashboard installed User Login: dgt User Pass: matagami2022	51999f151fc508c546ff6076b3a3a1e3	2.4 GB/8.4 GB
2	VMWare Matagami Core 2022 Image	VMWare-formatted VM image running Ubuntu 20.04 with Docker 20.10.2 deployed and DGT Matagami Core installed (no tokenization); no dashboard installed User Login: dgt User Pass: matagami2022

Basic steps to get started:

• Get ready: you must have at least 20 GB of free space available on your hard drive. You must install a program to support virtual machines (choose depending on the image used: VirtualBox, VMware Workstation Player/Workstation Pro).

• You should be able to unarchive a .rar archive (WinRar is recommended).

• You should have a basic understanding of the Linux system and its commands. Recommended: «Getting Started with Ubuntu 16.04» (This manual also covers the basic commands of the Linux system).

• Download the selected virtual machine image. Be sure that this is an authentic image – verify the checksum and compare it with the value in the table above. To get the checksum:

o For the Windows operating system: open the command line interface (Press Windows R, type cmd and press Enter), use the cd command to navigate to the folder where the file was downloaded and type the command certutil -hashfile <file> MD5, where <file> is replaced by the name of the archive loaded. The screen should display the checksum, which is what you need to compare to the value in the table above.

o For the Linux operating system: use the cd command to navigate to the download folder, type md5sum <file> to obtain the checksum, and compare the value to the data in the table.

• Expand the archive into a separate folder by using the archiver. Inside it, you will find virtual machine files – the configuration file and the virtual hard disk file. Open the file and edit the network interfaces by using a virtual machine manager (VirtualBox or VMWare). For more details, see VirtualBox.Virtual Networking and VMWare Virtual Networking Concepts.

• Launch the virtual machine and log in using your username and password (see the table above).

• Use the steps described below to control the startup of the node and conduct the necessary testing.
