Running the AsyncManager Example

If you have not done so already, launch the simple SNMP agent in examplesDir/Snmp/Agent, after making sure that no other agent is running on port 8085. The manager also requires the same OID table description that we generated for the synchronous manager. See "Running the SimpleManager Example" for instructions to do this.

Here we give commands for launching the agent and manager from the same terminal window running the Korn shell. On the Windows NT platform, you will have to launch each application in a separate window. We redirect the output messages since this agent sends traps periodically.

$ cd examplesDir/Snmp/Agent
$ java -classpath classpath Agent > Agent.out &

Now we can launch the manager application to connect to this agent. If you wish to run the manager on a different host, replace localhost with the name of the machine where you launched the agent.

$ cd examplesDir/Snmp/Manager
$ java -classpath classpath AsyncManager localhost 8085

You should then see the output of the SnmpWalkUntil request: the response handler method is called for each variable that is returned. Since this manager also has a trap listener running in a different thread, the output may be interspersed with trap reports.

When you are done with the agent, don't forget to stop it with the following commands:

$ fg
java [...] Agent > agent.out <Control-C>
^C$ rm examplesDir/Snmp/Agent/agent.out
