Package edu.internet2.ndt

Class OsfwWorker

java.lang.Object

edu.internet2.ndt.OsfwWorker

All Implemented Interfaces:

Runnable

public class OsfwWorker
extends Object
implements Runnable

OsfwWorker creates a thread that listens for a message from the server. It functions to check if the server has sent a message that is valid and sufficient to determine if the server->client direction has a fire-wall.

As part of the simple firewall test, the Server must try to connect to the Client's ephemeral port and send a TEST_MSG message containing a pre-defined string "Simple firewall test" of 20 chars using this newly created connection. This class implements this functionality. The result of the test is set back into the Tcpbw100._iS2cSFWResult variable (using setter methods) for the test results to be interpreted later
