To establish secure communication between the client and server over an insecure network, SSH is a helpful tool. Without a properly configured SSH connection, an attacker may be able to access your data across the network and damage your apps. The data sent over the network is encrypted and decrypted by SSH using RSA and other asymmetric encryption algorithms. When transmitting information via the network, such as bank account numbers and passwords, security of your data becomes increasingly crucial. Lack of security can result in significant losses for the client and the business. The security of your server will be improved by changing the default SSH port because it will make automated cyberattacks less likely. We mentioned below are the ways to enable SSH Into a VirtualBox Ubuntu Server.
Ways to Enable SSH Into a VirtualBox Ubuntu Server
Installing SSH on the Virtual Machine
One of the main methods for managing and connecting with Linux systems without a GUI is SSH. Of course, SSH is also usable in full-fledged desktop environments. An SSH server must be running on the system and its service must be activated in order to SSH into another PC. Additionally, an SSH client must be installed on the PC from which you are opening the SSH connection. Although the process is essentially the same no matter which operating system you use, this guide will use Ubuntu Desktop as the host OS and Ubuntu Server as the guest OS in VirtualBox. Here’s how to install Ubuntu as a guest operating system in VirtualBox if you don’t already have one. Launch VirtualBox and then start your Ubuntu virtual machine from the GUI.
Configuring the VirtualBox Network
For each of your virtual machines, VirtualBox automatically creates a Network Address Translation (NAT) adapter. This permits your virtual machine to connect to the internet but blocks SSH access from other devices. You must use VirtualBox port forwarding and the default NAT adapter your VM is connected to to configure the network. Although that’s a topic for another day, keep in mind that VirtualBox offers a wide range of additional networking configuration options, such as a bridged adapter that you can use to SSH into guest operating systems.
Final Words
That’s it with our article on how to Enable SSH Into a VirtualBox Ubuntu Server. The x86 computing architecture can be virtualized using the free and open-source programme VirtualBox. It performs the function of a hypervisor by generating a virtual machine (VM) in which the user can run another operating system. The “host” OS refers to the operating system that VirtualBox is running on. The “guest” OS refers to the operating system that is executing inside the VM. As a host OS, VirtualBox is compatible with Windows, Linux, and macOS.
