Making use of SNMP
13 Aug 2004: “The first thing to know about SNMP is that it is a service that is structured such that an SNMP agent sitting on a target host can be queried by remote hosts for various bits of information. Only the target host (the one you want information about) needs to be running an SNMP daemon. The client making the queries just needs some tool capable of making SNMP queries and parsing the output. Most Linux server and client tools are supplied by the Net-SNMP project.
