so, what about snmp?
in v1 it doesn`t show cpu, ram and interfaces. It`s useless at all.
I use LibreNMS for monitoring. This host was identified as a generic linux host.
But with no any sensors at all. Just ping and general snmp data.

updated to 2.2.0.
Still nothing interesting from SNMP. no CPU, RAM etc.
I disabled SNMP v1, but it still answered on "public" community and community I configured via WEB.
SNMP v2c is now working but with "public" community and community I configured via WEB.

Why it answered on "public" community?
