Arch Linux OS detecting as Grandstream

Help
1

Hi,

my Arch Linux boxes seem to all be detecting as Grandstream OS. I don’t have this issue with CentOS which correctly get recognized as Linux.

This is the output of the OS poller module:

Can you discovery.php -d -h <device> -m os ?

Hi, has there been any further development on this?

Unfortunately after an update recently of Librenms my Arch Linux machines are still getting detected as Grandstream phones… the machines in question are x86_64 based.
