# OpenVAS 8.0 Vulnerability Scanning
Vulnerability scanning is a crucial phase of a penetration test and having an updated vulnerability scanner in your security toolkit can often make a real difference by helping you discover overlooked vulnerable items. For this reason, we’ve manually packaged the latest and newly released OpenVAS (opens new window) 8.0 tool and libraries for Kali Linux. Although nothing major has changed in this release in terms of running the vulnerability scanner, we wanted to give a quick overview on how to get it up and running.
# Setting up Kali for Vulnerability Scanning
If you haven’t already, make sure your Kali is up-to-date and install the latest OpenVAS. Once done, run the openvas-setup command to setup OpenVAS, download the latest rules, create an admin user, and start up the various services. Depending on your bandwidth and computer resources, this could take a while.
root@kali:~# apt-get update
root@kali:~# apt-get dist-upgrade
root@kali:~# apt-get install openvas
root@kali:~# openvas-setup

Once openvas-setup completes its process, the OpenVAS manager, scanner, and GSAD services should be listening:
root@kali:~# netstat -antp
Active Internet connections (servers and established)

# Starting the OpenVAS services
If you have already configured OpenVAS, you can simply start all the necessary services by running openvas-start.
root@kali:~# openvas-start
Starting OpenVas Services
Starting Greenbone Security Assistant: gsad.
Starting OpenVAS Scanner: openvassd.
Starting OpenVAS Manager: openvasmd.

If you need to troubleshoot any issues, you can use openvas-check-setup to identity the problem.
# Connecting to the OpenVAS Web Interface
Point your browser to https://127.0.0.1:9392, accept the self signed SSL certificate and plugin the credentials for the admin user. The admin password was generated during the setup phase (look at the output above if you missed it).
openvas vulnerability scanner
That’s it! Now OpenVAS is ready for you to configure it and run a scan against a given IP or range. Happy vulnerability scanning!

注意：
如果不小心忘记了OpenVAS的Web登录密码或者没有找到OpenVAS安装过程中输出的默认密码，则通过如下的命令修改OpenVAS的Web登录密码：
openvasmd --create-user --help
openvasmd --user admin --new-password '新密码'
2
这样我们就可以将OpenVAS的Web密码修改为新密码，从而登录OpenVAS的Web端。
