Program not capturing
I have a program running as an alerting system in my station. I am brand new to Java and learning as I go. Anyway the program compiles and runs but does not capture any of the packets. Im hoping you all can give me a little input on what I am missing. Thanks in advance.
Listener
package prealert;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import jpcap.JpcapCaptor;
import jpcap.NetworkInterface;
public class Listener {
private NetworkInterface[] devices;
private NetworkInterface deviceName;
private Reciever Reciever;
private JpcapCaptor jpcap;
public static Logger log;
public Listener() {
PropertyConfigurator.configure("log4j.properties");
log = Logger.getRootLogger();
log.debug("Log4j has been initialized");
devices = JpcapCaptor.getDeviceList();
for (int i = 0; i < devices.length; i++) {
log.info(devices[i].description);
}
deviceName = devices[1];
Reciever = new Reciever();
try {
jpcap = JpcapCaptor.openDevice(deviceName, 2000, true, 100);
} catch (Exception e) {
log.error("Error with JPcapCreation", e);
}
Reciever.jpcap = jpcap;
Reciever.start();
new SetBoard(SetBoard.DEFAULT).start();
}
public static void main(String args[]) {
try {
Listener listener = new Listener();
} catch (Exception e) {
log.error("ERROR IN THE MAIN METHOD OF LISTENER!", e);
}
}
}
