The Subordinate Scanners area is where you configure additional DeepSurface installations. For instance, if you need to segment the scans on different parts of your site, setting up subordinate installations is helpful.
Go to Scanning > Settings > Subordinates. You should see a screen that looks like the following.
Notice the icons for adding, editing, and deleting subordinate scanners.
To add a Subordinate scanner click on the + Subordinate Scanner button. You will see a form that looks like this.
Enter a Name for your subordinate scanner in the New field
Click the Save button to continue. You will get an informational screen that looks like the following. Notice the download link at the bottom of the modal.
Here are the steps
Step 1 - Download the registration file to a convenient location. Step 2 - Copy the file to your new DeepSurface Virtual Machine (the one which will be your subordinate server).
We recommend you set up an SSH connection to your VM so that you can login with a regular terminal to more easily copy/paste, etc. If you are using VirtualBox and would like to share a file folder, you need to set up Guest Additions. See here for some brief instructions.
Step 3 - Create a DeepSurface Virtual Machine for your subordinate scanner as described in the Virtual Machine Instructions
Step 4 - Configure the Virtual Machine's network settings as described in the those Virtual Machine instructions.
Step 5 - Login to the DeepSurface Virtual Machine for your subordinate scanner and run the following command.
sudo deepsurface-install
Step 6 - You will first get a screen asking you to accept the license agreement. Select "<AGREE>".
Step 7 - The next screen asks if you would like to install a DeepSurface main console or a subordinate, at which point you should choose "SUBORDINATE". See the following screenshot.
Step 8 - You can either paste the contents of the subordinate registration file into the console or upload the file to the new system (via SCP, SFTP, or another method) and choose the file from the filesystem. Select "<CHOOSE FILE>" to choose the file from the VM host's filesystem after copying it. If you prefer to paste the file, select the "<PASTE FILE>" option and paste the file contents when the text box appears.
Step 9 - Choose "<OK>". At this point the new DeepSurface subordinate scanner will attempt to connect to the DeepSurface main console on a port and IP address provided by the main console. That information can sometimes be incorrect (e.g. if NAT is in use). If the subordinate scanner fails to contact the main console, you will be prompted to enter different IP and port information. Subordinates can contact the DeepSurface main console on either port 443/TCP or 44305/TCP.
After successfully completing this process, the subordinate's status in the web console will change from "unregistered" to "online". See the following two screenshots for an example.
