I’m having some odd trouble adding a ping only device to LibreNMS. First off here is my validate and an fping from the cli:
$ ./validate.php
| Component | Version |
|---|---|
| LibreNMS | 24.5.0-39-g3ad5bbc83 (2024-06-10T20:06:19-04:00) |
| DB Schema | 2024_04_29_183605_custom_maps_drop_background_suffix_and_background_version (294) |
| PHP | 8.1.28 |
| Python | 3.8.10 |
| Database | MariaDB 10.3.39-MariaDB-0ubuntu0.20.04.2 |
| RRDTool | 1.7.2 |
| SNMP | 5.8 |

$ fping 10.40.255.2
10.40.255.2 is alive
Yet when I try to add the ip I get:

If I force add it with no checks it predictably lists as offline, but in that state I can run the lnms poller:ping from the cli and it’ll successfully ping (only once then go “offline” again).
Any ideas of what I could try would be appreciated.
