so what you say is that SNMP has to be installed on a Linux box, since
Linux does not 'speak' SNMP out of the box?
Then I have 2 questions:
1. does SNMP eat much CPU power? (it is going to run on a PI/133MHz/40MB
which is used for firewal/gateway/mailserver/proxy etc. for a small local
network)
2. which package should I install? snmpd?
Thanks,
