How can you access the packet information in a JpCap Packet

How can I pull relevant packet information from a JpCap packet? I am trying to find the source/destination ip and port. So far I have tried string parsing the Packet's to开发者_如何学编程String() method, but that seems brutish.


You have to cast the Packet object to the correct type of Packet i think.

So something like:

TCPPacket p = (TCPPacket)packet;

// Get the tcp src and dest ports
int destPort = p.dst_port;
int srcPort = p.src_port;

// Get the src and dest IP addresses from the IP layer
InetAddress destIp = p.dst_ip;
InetAddress srcIp = p.src_ip;


Here is a good example about accessing packets information using Jpcap Packet
