Installing a Scan Agent on Linux (Debian Distribution)

If you want to scan a website in a demilitarized zone (DMZ), internal networks that are not publicly accessible, you can install Acunetix scan agents in your network. You can install Acunetix 360 scan agent on a Linux operating system. If you choose this installation, you must install some dependencies on the system, such as .NET, Mono. This is an alternative method for installing Acunetix 360 Scan Agents.

Mono is a software platform designed to allow developers to easily create cross-platform applications that become part of the .NET Foundation.

This topic explains how to install a Acunetix 360 scan agent on Linux (Debian distribution) operating systems.

How to Install an Acunetix 360 Scan Agent
  1. First, update the following operating system application repositories:

sudo apt update && sudo apt upgrade -y

  1. Install the following package as NTLM authentication is required by the agent:

sudo apt install -y gss-ntlmssp

  1. Next, install dotnet-runtime-3.1 for Linux operating systems.

Information

If you've already installed the SDK or runtime, use the dotnet --list-sdks and dotnet --list-runtimes commands to see which versions are installed.

wget https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb

sudo dpkg -i packages-microsoft-prod.deb && sudo apt update

sudo apt install -y apt-transport-https dotnet-runtime-3.1

  1. Next, install Mono. The following dependencies are not only for installing Mono. In addition, the gnupg and ca-certificates will be used to check the digital signatures of the libraries:

sudo apt install -y gnupg ca-certificates

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF

We're adding official keys for Mono to check the integrity of the file.

  1. Add the following official Mono repository into the repository addresses that will be used by the Linux operating system:

echo "deb https://download.mono-project.com/repo/debian stable-buster main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list

  1. Update the repository with the latest link:

         sudo apt update

  1. Next, install Mono:

       

      sudo apt install -y mono-complete

  1. Install the Headless Chrome browser:

            Dependencies for Chrome browser:

sudo apt install -y gconf-service libasound2 libatk1.0-0 libatk-bridge2.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget

  1. Next, to run the Acunetix 360 Scan Agent, first extract the TAR file:

tar xf Acunetix_360_Scanner_Agent.tar

chmod +x .local-chromium/Linux-*/chrome-linux/chrome

            Open appsettings.json file via any text editor you prefer, for example:

nano appsettings.json

These settings will be used by the scan agent:

  • AgentName
  • This can be anything you want. This text will be displayed when you are starting a new scan. (If you are going to install more than one instance of the agent, you must set a unique agentName value for each instance, something you will use later.)
  • AgentType
  • This can be Standard or Cloud. If you want to use Cloud Provider for scanning, AgentType must be Cloud.
  • ApiRootUrl
  • This is the URL of Acunetix 360 or the Acunetix 360 On-Premises.
  • ApiToken
  • In Acunetix 360, the Agent Token is displayed in the Configure New Agent window. Copy the value into the apiToken.
How to Get an Agent Token for the Scan Agent
  1. Log in to Acunetix 360.
  2. From the main menu, click Agents and then Manage Agents. The Agents window is displayed.

  1. Click Configure New Agent. The Configure New Agent window is displayed.

  1. In the Agent Token field, click Copy to clipboard ().
  2. Completing the required fields with the relevant values.
  1. To start the scan agent, enter this command:

dotnet Acunetix.Cloud.Agent.dll

You can see that the scan agent has started and is working as expected.

  1. In Acunetix 360, you can check the status of the connection between it and the scan agent. From the Agents menu, click Manage Agents. The Agents window is displayed.

  1. Now, we can start a scan through the recently installed scan agent. From the main menu, click Scans, then New Scan. The New Scan window is displayed.
  2. Select a website whose Agent Mode is Internal. Then, along with the other settings required to start a scan, we can also select which Preferred Agent should be used to scan the target.
