I have started playing around with the jpcap classes for java and I would like to use some stuff I saw in the IPAddress package(setAddressConvert(boolean isDomainName), getHostName(), getHostAddress(), toString() )
 and was wondering if anyone new of a site where I could get more info on how to use them or if anyone could post some sample code would be great. I looked through the api manual, but I like to see examples.

Thank you to all

am not familiar with jpcap package or IPAddress class, but have you looked at InetAddress class in java.net package?.....sound like is something similar to what you want.

what sort of info are you after? (be specific)

I had already looked through the API Manual at the from the link listed by mayankeagle and it doesn't tell me much. I like to see examples. I haven't looked at the InetAddress, I was looking at the packet capturing side and wanted to use jpcap because it does that. I don't think the InetAddress class would handle that.

You've seen this example? Is from the same site as the link above.
To get it work you need libcap from: http://www.tcpdump.org/


import jpcap.*;

class Tcpdump implements JpcapHandler
{
   public void handlePacket(Packet packet){
     System.out.println(packet);
   }
 
   public static void main(String[] args) throws java.io.IOException{
     String[] lists=Jpcap.getDeviceDescription();
     System.out.println("Start capturing on "+lists[0]);

     Jpcap jpcap=Jpcap.openDevice(Jpcap.getDeviceList()[0],1000,false,20);
     jpcap.loopPacket(-1,new Tcpdump());
   }
}

Another link I've found:

http://jpcap.sourceforge.net/

setAddressConvert(boolean isDomainName), getHostName(), getHostAddress(), toString() )

I've seen it and ranit and it doesn't tell me anything about the items that I am looking for. I also found the visual JpcapDumper, but I can't figure out how it displays the destination host name and source hostname. That's really what I am looking for is how to capture packets witht he jpcap package and display the destination ip and url. So if I went to say the experts exchange website I would see(this is not the real ip of the expert's exchange)
68.45.98.109 www.experts-exchange.com the tcpdump program shows how to capture packets, but nothing more. I wish they would have more examples listed.
