2 Setting up OpenSight OS

2.1 Setup Requirements

OpenSight Operating System (OpenSight OS) is provided by Greenbone as a virtual machine (VM). It requires and is limited to the following resources:

  • 64-bit Linux operating system

  • 4 vCPUs

  • 16 GB RAM

  • 1000 GB SSD storage

The following hypervisors are officially supported:

  • VMware vSphere Hypervisor (ESXi), version 7.0 or higher

  • Microsoft Hyper-V, version 6.0 or higher

2.2 Setting up the Virtual Machine

2.2.1 Verification of Integrity

Note

The integrity of the VM can be verified. On request, the Greenbone Enterprise Support provides an integrity checksum.

To request the checksum, contact the Greenbone Enterprise Support.

The integrity checksum can be provided via phone or via support portal.

The local verification of the checksum depends on the host operating system.

On Linux systems, the following command for calculating the checksum can be used:

sha256sum <file>

Note

Replace <file> with the name of the VM’s OVA file.

On Microsoft Windows systems, the following command for calculating the checksum can be used in the Windows PowerShell:

Get-Filehash 'C:\<path>\<file>' -Algorithm SHA256

Note

Replace <path> and <file> with the path and the name of the VM’s OVA file.

If the checksum does not match the checksum provided by the Greenbone Enterprise Support, the VM has been modified and should not be used.

2.2.2 Setting up the Virtual Machine

The VM is provided by Greenbone in the Open Virtualization Appliance (OVA) format.

To deploy the VM, it has to be imported into the hypervisor of choice as follows:

  1. Download the VM image from the URL provided by Greenbone.

  2. Import the VM image into the selected hypervisor and start the VM.

    → The VM will boot and after a short time a prompt for setting a new root password is displayed.

    Note

    The root password must be stored securely, for example in a password manager, as it cannot be revoked.

  3. Enter a new root password and press Enter.

  4. Repeat the new password and press Enter.

    → After the root password is set, a prompt for logging in is displayed.

  5. Enter the user name admin and press Enter.

    → A prompt for setting a new admin password is displayed.

  6. Enter a new admin password and press Enter.

  7. Repeat the new password and press Enter.

    → The command line interface (CLI) of OpenSight OS is opened.

    Note

    Follow the instructions in Chapter 3 to configure OpenSight OS.

    • After the initial setup, it is recommended to check for OpenSight OS updates (see Chapter 3.5).

    • For deploying up OPENVAS products, SSH must be enabled (see Chapter 3.4).
