Once you have installed DSM, and gone through initial setup, you will want to install VMware Tools. We enable this through the use of a Docker container. Go to package manager, and install Docker.
Enable SSH in DSM, and connect via SSH.
Once you have established a successful SSH connection, type the 2 commands below. (Or copy and paste..)
sudo mkdir /root/.ssh
sudo docker run -d --restart=always --net=host -v /root/.ssh/:/root/.ssh/ --name open-vm-tools yalewp/xpenology-open-vm-tools
