I have not really posted on THWACK before but am having trouble completing a task that was assigned to my by management. We want to run a regularly scheduled scan to identify all windows and linux servers on our network and use this for inventory purposes.
I know I can perform a network discovery and find MANY devices on my network. I have an Active Directory service account with enough access to utilize WMI to discover/identify windows servers with no issues. My problem is that we have Linux servers on our network that all have different credentials and are not configured (yet) for SNMP. When I run a discovery it identifies these systems as IP Addresses (if no DNS entry had been assigned to them) and as ICMP only, along with many other devices.
How am I able to be sure I am identifying only SERVERS and not network devices, VIPs, cluster IPs, etc? Once we identify the IPs that we know there is a server OS associated with then I can work to whittle down the list by getting the application owner to install SNMP, etc.
Any assistance would be greatly appreciated.
