All Implemented Interfaces:
ServiceMonitor

public final class Pop3Monitor
extends IPv4LatencyMonitor

This class is designed to be used by the service poller framework to test the availability of the POP3 service on remote interfaces. The class implements the ServiceMonitor interface that allows it to be used along with other plug-ins by the service poller framework.

Method Detail

poll

public int poll(NetworkInterface iface,
                java.util.Map parameters,
                Package pkg)

Poll the specified address for POP3 service availability.

During the poll an attempt is made to connect on the specified port (by default TCP port 110). If the connection request is successful, the banner line generated by the interface is parsed and if the response indicates that we are talking to an POP3 server we continue. Next, a POP3 'QUIT' command is sent to the interface. Again the response is parsed and verified. Provided that the interface's response is valid we set the service status to SERVICE_AVAILABLE and return.

Parameters:
iface - The network interface to test the service on.
parameters - The package parameters (timeout, retry, etc...) to be used for this poll.
Returns:
The availibility of the interface and if a transition event should be supressed.
