daemons on Redhat:
/etc/init.d/snmpd (daemon that sits and wait for a SNMP agent to make requests, and then processes them)
/etc/init.d/snmptrapd (Receive and log SNMP trap messages).
snmpwalk: communicates with a network entity using SNMP GETNEXT requests.
snmpwalk -Os -c public -v 1 localhost system
-O specifies output string options.
-Os Deletes all but the last symbolic part of the OID
-c sets the community string (public in the example)
(overriding the default community specified in snmp.conf)
-v specifies the protocol version to use.
(protocol options are 1, 2c, 3)
