snmpget()获取一个 SNMP 对象
snmpwalk()从代理返回所有的 SNMP 对象

with snmpget api, the agent returns the value associated 
with the OID (or OIDs) specified in the original request.
The snmpgetnext api is similar, but the agent returns the 
value associated with the next (valid) OID
eg:
snmpgetnext('192.168.40.134',
          'public',
          'SNMPv2-MIB::sysUpTime.0');
will give the output:
STRING: user@hostname
