Network scan is a tool for discovering devices in the network.

Unimus will ping (ICMP) all IPs in the list of provided subnets / address ranges, and check whether service(s) defined in the enabled Default Connectors (SSH and/or Telnet) are available on reachable devices.

It's possible to scan devices in a specific Zone, and devices discovered by such a scan will be imported into this zone in Unimus (if automatic device creation is enabled).
Remote Cores are fully supported, and if a Zone utilizes a Remote Core, it will be used for scanning.

Scan Presets

To set up a Network scan, you need to create a Preset. In the Preset, you specify subnets and/or address ranges to scan, select the Zone for this scan, and (optionally) set up a schedule when the scan should run.

To select which addresses should be scanned, you have multiple input options:

# Supported input formats:
subnet: 172.16.0.0/16
range: 172.16.0.0-172.31.255.255
address: 172.24.5.11

To exclude a specific subnet or address from the scan, use the '-' (minus sign), e.g., "-10.0.0.1". (meaning these address will not be scanned)

Scans and Zones

As mentioned previously, Scan Presets are assigned to a Zone. If the selected Zone utilizes a Remote Core, it will be used for scanning.

If the Zone assigned to a Preset is deleted and the devices are migrated to a new Zone during Zone deletion, the new Zone is assigned to all Scan Presets that belonged to the previous Zone as well.
When a Zone is deleted along with all its devices, the Default Zone is automatically assigned to any existing presets.
