On the machine being monitored, check the snmpd configuration file, you will find some items like following:

	$ cat /etc/snmp/snmpd.conf
	rocommunity public 
	rwcommunity admin
	agentaddress tcp:161
	If you want to enable Location and contact, add:
	syslocation Bat. C2
	syscontact someone@somewhere.org

On the monitor PC, we can use following command to view the monitored machine’s status:

	or
	$ snmpwalk -c Trusty -v 2c 10.0.0.221
