How to access virtual machines in the Big Data Lab

There are several ways you can access Virtual Machines (VMs) in the Big Data Lab. VMs can be accessed through the vSphere client, Remote Desktop, or SSH. To access VMs remotely, you must first connect to the Computer Science VPN.
Edit me

VMs in the Big Data Lab can be accessed through the vSphere Web Client, vSphere Desktop Client (Windows only), though Remote Desktop Connection (only for Windows VMs), or through SSH (only for Linux VMs). In order to access virtual machines from your laptop, from lab computers outside of Adams and Weed Hall, or from anywhere off campus, you must first connect to the Computer Science VPN. Big Data Lab VMs are subject to the Virtual Machine Policy and the Acceptable Use Guidelines.

vSphere Web Client (HTML5 version)

  1. Launch a web browser. On computers in Adams 204 or 019, launch Google Chrome (under Applications->Internet, or type “google-chrome” in terminal)

  3. Click on the VMs button.

  4. Select the desired VM.

  5. Open the remote console to access the VM.

Remote Desktop Connection

Remote Desktop can be used to access Windows virtual machines. It provides better performance and additional features such as audio and remote printing. The following shows you how to use Remote Desktop Connection on Windows; however, it is also available for macOS (OS X) in the app store.

  1. Launch “Remote Desktop Connection” from the Start menu.

  2. Enter the name or IP address of the virtual machine you want to connect to. The name or IP address may be observed in the vSphere Client or provided by your professor.

  3. Login to the VM using your windows credentials. Alternatively, you can sign in as another user by clicking more choices. Usually, the username is “admin”, but check with your instructor if you are unsure.

SSH access

Linux VMs can be accessed on the command line through SSH as follows:

ssh user@ip-address

…where ip-address is your VM’s IP address and user is the username of the account on your VM.
