ansible

Prepare ubuntu 21.04 VM

Download newest ubuntu version from https://ubuntu.com/#download

Insert ubuntu Live CD in Virtual CD-ROM of Virtualbox

Configuration for Virtualbox VM Network

• Bridget Adapter
• Name of host ethernet adapter
• Promiscuous Mode: Allow VMs
• Cable connected

Start VM

install open-ssh on VM

sudo apt-get install openssh-server

add new user as admin on VM

sudo adduser <userName>
sudo usermod -aG sudo <userName>
# verify user as admin
sudo - <userName>

add IP-Address to hostsfile on HOST

add IP-ADDRESS with

vi /etc/hosts

Create .ssh directory if not exists

A better approach is the following command

ssh-copy-id <userName>@<VM-Name>

which does all the following automatically

or manually

mdir ~/.ssh
chmod 700 ~/.ssh

copy ssh public key to new user home directory from HOST

sudo scp ~/.ssh/id_rsa.pub <userName>@<VM-Name>:.ssh/authorized_keys
# verify ssh connection
ssh <userName>@<VM-Name>
