Gather and normalize ICT inventory data from multiple sources, to enable automation of ICT carbon and environmental impacts (LCA-inspired) assessments.
As a network administrator, I want to use cabestan to inventories the devices on my network from a network scan
Solution
Using nmap we can scan an IP range, identify some information about devices behind the IP address.
Feature 1 : Host discovery
Doc :https://nmap.org/book/host-discovery.html
Scan a range of IPs to list the IP identifying a running device. This let us gather a list of address that can be used to call running devices connected to the network. As IP might change over time, they shouldn't be used to identify a device.
MAC address are unique identifier for device ethernet interfaces. They could be used in our case as :
a primary key to identify a device. /!\ (1) MAC address could be manually modified even if it is highly unlikely (2) Several MAC addresses can identify one device with several Ethernet interfaces
a way to determine network physical interface vendors
Nmap can tag a device in the network with a type according to it's matching algorithm. The list of device types can be found in the doc.
This could be useful to characterize the device.

Feature 3 : Remote OS Detection
Doc : https://nmap.org/book/osdetect.html
This feature allows us to detect which OS the device is running on. This could be very useful to characterize the device.
Feature 4 : Device type

Nmap can tag a device in the network with a type according to it's matching algorithm. The list of device types can be found in the doc. This could be useful to characterize the device.
Feature 5 : Application and services
Doc : https://nmap.org/book/vscan.html
This feature allows us to inventories some services reachable over the network. It can be used to :
