I just spent 48 hours installing and configuring Librenms on a Debian LXC under Proxmox – just for giggles (yes, I’m down to 3 brain cells left).
I’ve been using The Dude but frustrated that the devices (in Device List or on map, etc.) show only IP and MAC as identifying info.
It would be so so so much nicer to have HOSTNAME/DNS/Windows-Discovery-Devicename/etc.
I have the wonderful “DHCP TO DNS” script that adds DHCP lease info to the local router’s static DNS table.
And I see that each router maintains an ARP tables that associates MAC to HOSTNAME.
My questions are:
How can we get the info from the arp table associating MAC to HOSTNAME to show up in The Dude’s device record?
How can we get the static DNS entries of each router (from multiple locations) into The Dude’s device record?
Thank you.
