![]() It is even best to use an agent from the same network than the scannedĭevices so it can access the local system arp table. To send UDP packets to a device is not enough, if this device is configured to The agent performing the task needs network access the target networks, withįorementioned protocols, as well as control access, for SNMP: just being able The agent performing the task needs to have the netdiscovery module installed. Devices not matching any importĬriteria will be kept in a server list of ignored devices. Is reported as linux with the 8072.3.2.10 model-specific suffix, the LinuxAppliance MibSupport module usage is triggered and permits to inventory Synology or Ubiquiti devices.ĭiscovered devices are then reported to the GLPI servers, where import In order to identify the device, with lower reliability.Ī secondary method relies on GLPI Agent MibSupport feature which permits to implementĭedicated perl module for any kind of device. If no match is found, various heuristics are performed Manufacturer are added to the information reported to the GLPI server, allowing The agent internal database (the sysobject.ids file, described in SNMP device IDS database). The dedicated SNMP variable ( SNMPv2-MIB::sysObjectID.0), which is aĬonstructor-specific OID identifying a given device model, and comparing it to The primary method relies on retrieving the value of ![]() With minimal information, such as mac address and hostname.Īdditionally, if the device replies to SNMP, the agent will attempt to identify SNMP scan (if Net::SNMP is available, and proper credits provided)Īny device replying to at least one of those protocols will be discovered, NetBIOS scan (if Net::NBName is available and proper credits provided) ICMP Echo (aka ping) with fallback on ICMP Timestamp scan 1 This task uses the following protocols to scan IP networks:Īrp local table request with arp -a command or ip neighbor show command Once part of the list of known assets, further information can be retrievedįrom SNMP enabled devices using Network inventory. A network discovery task aims to scan the the network and reports devicesįound to the GLPI server, so they can be added to the list of known assets.
