NetAlertX/front/plugins/arp_scan

Overview

Most on-network scanners (ARP-SCAN, NMAP, NSLOOKUP, DIG, PHOLUS) rely on scanning specific network interfaces and subnets. Check the subnets documentation for help on this setting, especially VLANs, what VLANs are supported, or how to figure out the network mask and your interface.

An alternative to on-network scanners is to enable some other Device scanners/importers that don't rely on NetALert^X having access to the network (UNIFI, dhcp.leases, PiHole, etc.).

Note: The scan time itself depends on the number of IP addresses to check so set this up carefully with the appropriate network mask and interface.

Usage

• Go to settings and set the SCAN_SUBNETS setting as per subnets documentation.
• Enable the plugin by changing the RUN parameter from disabled to your preferred run time (usually: schedule).
  • Specify the schedule in the ARPSCAN_RUN_SCHD setting
• Adjust the timeout if needed in the ARPSCAN_RUN_TIMEOUT setting
• Review remaining settings
• SAVE
• Wait for the next scan to finish
