Installation

gvm

This package installs all the required packages

It provides scripts to setup, start and stop the GVM services.

$ sudo apt install gvm

gvm-check-setup

# gvm-check-setup -h
gvm-check-setup 22.4.0
  Test completeness and readiness of GVM-22.4.0
Step 1: Checking OpenVAS (Scanner)... 
        OK: OpenVAS Scanner is present in version 22.4.0.
        OK: Notus Scanner is present in version 22.4.1.
        OK: Server CA Certificate is present as /var/lib/gvm/CA/servercert.pem.
Checking permissions of /var/lib/openvas/gnupg/*
        OK: _gvm owns all files in /var/lib/openvas/gnupg
        OK: redis-server is present.
        OK: scanner (db_address setting) is configured properly using the redis-server socket: /var/run/redis-openvas/redis-server.sock
        ERROR: redis-server is not running or not listening on socket: /var/run/redis-openvas/redis-server.sock
        FIX: You should start the redis-server with 'systemctl start redis-server@openvas.service' or configure it to listen on socket: /var/run/redis-openvas/redis-server.sock

 ERROR: Your GVM-22.4.0 installation is not yet complete!

Please follow the instructions marked with FIX above and run this
script again.

Fehlerbehebung

There is a lot that can go wrong during the installation of OpenVAS as some of our readers has pointed out, therefore, we decided to create a little extra section here, covering the most common errors.

PostgreSQL Version Errors v13 and v14

There are multiple possible version errors for PostgreSQL. As our reader Tom has pointed out, the first one is:

[>] Starting PostgreSQL service[-] ERROR: The default PostgreSQL version (13) is not 14 that is required by libgvmd[-] ERROR: Use pg_upgradecluster to update your PostgreSQL cluster

Solution:

Open the postgresql.conf file of version 14 and change the port to 5432:

sudo nano /etc/postgresql/14/main/postgresql.conf

Then open the postgresql.conf file of version 13 and check if the port is the same as in version 14. If it is the same – change it to 5433:

sudo nano /etc/postgresql/13/main/postgresql.conf

Restart the PostgreSQL service:

sudo systemctl restart postgresql

PostgreSQL Version Errors v14 and v15

During my installation, I got the following error affecting v14 and v15 of PostgreSQL:

[>] Starting PostgreSQL service[-] ERROR: The default PostgreSQL version (14) is not 15 that is required by libgvmd[-] ERROR: Use pg_upgradecluster to update your PostgreSQL cluster

Gladly, the solution to this problem was easier than the one above and might as well work for the problem above:

sudo systemcctl stop postgresql@14-main
sudo /usr/bin/pg_dropcluster --stop 14 main

OpenVAS failed to find config

Another common error is the failed to find config ‘long-string-value’ message. There are multiple possible solutions for this issue. The one that worked for me is the following:

sudo runuser -u _gvm – gvmd --get-scanners

Note down the scanner ID.

Then run:

sudo runuser -u _gvm – gvmd --get-users --verbose

This gives you the users, including their IDs. You are probably an admin. To solve the issue, enter:

sudo runuser -u _gvm – gvmd --modify-scanner [scanner id] --value [user id]


Install

The first thing we want to do is to make sure that our Kali installation is up-to-date. So open a terminal window and run:

sudo apt update && sudo apt upgrade -y

This will update your repository and upgrade your Kali, the -y at the end saves you a press of the button “Y” in the process.

The next thing we want to do is to install OpenVAS. Again in the Terminal type:

sudo apt install openvas

Confirm that you are aware that an additional ~1,2 Gigabyte of Disk Space will be used by pressing Y.

Now this will take a good while.

Once that is done we will run another command in the terminal window:

sudo gvm-setup

Note: In case you run into a PostgreSQL error – check out the troubleshooting section at the end of this article.

This is going to take very long.

"Install OpenVAS on Kali Linux"

Phew… That took about 2 hours for me to finish. I still didn’t get why it takes so long, but just go for a long walk and come back later…

After the setup process is finished, don’t forget to note down your password that was generated at the end, you need it to log in for the first time.

"Install OpenVAS on Kali Linux"

Installing

To install Openvas and its dependencies on our Kali Linux system run the following command:

sudo apt update                   
sudo apt upgrade -y
sudo apt dist-upgrade -y
sudo apt install openvas
  • The next step is to run the installer, which will configure OpenVAS and download various network vulnerability tests (NVT) or signatures.
  • Due to a large number of NVTs (50.000+),  the setting process may take some time and consume a lot of data.
  • In the test setup we used for this tutorial, the complete setup process took 10 minutes, which is not bad.

Run the following command to start the setup process

# gvm-setup

After the configuration process is complete, all the necessary OpenVAS processes will start and the web interface will open automatically.

  • The web interface is running locally on port 9392 and can be accessed through https://localhost:9392.
  • OpenVAS will also set up an admin account and automatically generate a password for this account which is displayed in the last section of the setup output:

Verify the Installation

You can verify your installation

# gvm-check-setup
After the setup completes, you will find two listening TCP ports
9390 and 9392

Port 9392 is likely the one of most interest to you as it is the web interface for OpenVAS. You can open the web interface using your browser of choice.
