SNMP master agent

This version includes the SNMP master agent, which is a public domain SNMP agent, freely obtainable from the J.AgentX Web site. You can also use your own SNMP master agent if it is AgentX-enabled. The SNMP master agent works with the SNMP protocols SNMPv1, SNMPv2, and SNMPv3.

If you use the SNMP master agent that is included in this release, you can specify the ports it uses by supplying suitable arguments to the start-up script SybMaster.sh or SybMaster.bat, located in ROOT/bin. The default SNMP UDP (User Datagram Protocol) port is 7776. The default port used by the AgentX protocol is 7777, and this is the port that the JMX agent connects to using its default configuration file.

Configuring the SNMP master agent

If you have an SNMP client tool that listens for traps, you can configure the master agent to send SNMP traps to a designated trap receiver by setting the SEND_TRAPS variable:

1. Change to the ROOT/bin directory.

2. Open the master.conf file and edit the values that you want to change. The following master.conf file is included with EAServer:

   ############################################
   # SNMP eXtensible Agent configuration file #
   ############################################
   VERBOSE=false
   SNMP_UDP_PORT=7776
   AGENTX_UDP_PORT=7777
   #SNMP_UDP_PORT=161
   #AGENTX_UDP_PORT=705
   
   # Values to fill in the system node of the MIB
   SYS_DESCR=SNMP eXtensible Agent developed at University of Coimbra, Portugal
   SYS_OBJECTID=0.0
   SYS_CONTACT=agentx@dei.uc.pt
   SYS_NAME=J.AgentX
   SYS_LOCATION=UC-PT
   SYS_SERVICES=0
   
   # IP and UDP port from the managers that receive the traps
   SEND_TRAPS=localhost:162;
   
   # Views over the MIB implemented in the master agent - note that
   # the SNMP MIB module is read only.
   VIEWS=public:system.read/snmp.read/agentx.read;admin:system.readwrite/
   snmp.read/agentx.readwrite;
   

Starting the SNMP master agent

1. Change to the ROOT/bin directory, and enter:On UNIX or in an MKS shell on Windows – SybMaster.sh [-v]

   On Windows – SybMaster.bat [-v]

   Use the -v option to generate more verbose output. SybMaster writes output to master.stdout, in the EAServer SysMgmt directory.

Stopping the SNMP master agent on UNIX

1. Find the SybMaster process number and kill the process; for example:

   ps -ef | grep java
   kill -9 <process_ID>
   

   You can also run these commands from an MKS shell on Windows.

Stopping the SNMP master agent on Windows

1. In the SybMaster window, enter Ctrl-C.
