Example of installing a root certificate
C:\Program Files\Java\j2re1.6.0\bin> keytool -import -alias RootCert -file
RootCert.crt -keystore ..\lib\security\RootCerts
Enter keystore password: changeit

In the example, changeit is the default password and RootCert is an example root certificate name.
Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is a set of protocols for managing complex
networks. SNMP protocols are application layer protocols. Using SNMP, devices within a network
send messages, called protocol data units (PDUs), to different parts of a network. Network
management using SNMP requires three components:
• SNMP Manager
• SNMP Agent
• Management Information Base (MIB)
SNMP Manager
The SNMP Manager can communicate to the devices within a network using the SNMP protocol.
Typically, SNMP Managers are network management systems (NMS) that manage networks by
monitoring the network parameters, and optionally, setting parameters in managed devices.
Normally, the SNMP Manager sends read requests to the devices that host the SNMP Agent, to
which the SNMP Agent responds with the requested data. In some cases, the managed devices
can initiate the communication, and send data to the SNMP Manager using asynchronous events
called traps.
SNMP Agent
The SNMP agent is a software that resides in the managed devices in the network, and collects
data from these devices. Each device hosts an SNMP Agent. The SNMP Agent stores the data, and
sends these when requested by an SNMP Manager. In addition, the Agent can asynchronously alert
the SNMP Manager about events, by using special PDUs called traps.
