How to interpret packets?
I have developed a program using JPCAP in java,which will capture packets and display it received by my pc but the problem is that output is not understandable by me
when i execute that program and enter the url address in web browser say Google.com,it displays me output like this
1277469255:706879
1277469255:708581
what does it means?Is there any possible way to extract header ,length ,type of packet and data that resides in that program
This is my program

import jpcap.*;

import jpcap.packet.TCPPacket.*;
import java.net.InetAddress;
class NetworkList
{
public static void main(String args[])throws IOException
{
int i;
try
{
NetworkInterface[] devices = JpcapCaptor.getDeviceList();
for (i = 0; i < devices.length; i++)
{
//print out its name and description
System.out.println(i+": "+devices[i].name + "(" + devices[i].description+")"+devices[i].loopback);
}
JpcapCaptor captor=JpcapCaptor.openDevice(devices[0], 65535, false, 20);
for(i=0;i<10;i++){
System.out.println(captor.getPacket());
}
captor.close();
}
catch(Exception e)
{
System.out.println(e.getMessage());
}
}
}I have also tried using captor.getPacket().data ,but then it throws null exception
