    Post keep ip address event

    I want to keep track ip address where have 135 destination port then in next packet with same ip address have 4445 destination port. I try the code at below, but can't run it. how to solve it? please help.Thanks.



    packet = jpcap.getPacket();
    if(packet instanceof IPPacket){
    IPPacket ipp = (IPPacket)packet;
    InetAddress destAdd = ipp.dst_ip;
    InetAddress srcAdd = ipp.src_ip;
    if(ipp instanceof TCPPacket){
    TCPPacket tcp = (TCPPacket)ipp;
    int destPort = tcp.dst_port;
    int srcPort = tcp.src_port;
    if(destPort == 135 || destPort == 445)
    {

    System.out.println(srcAdd + " " + destAdd + " " +srcPort + " " + destPort);
    Packet packet2 = jpcap.getPacket();
    if(packet2 instanceof IPPacket){
    IPPacket ipp2 = (IPPacket)packet2;
    InetAddress destAdd2 = ipp2.dst_ip;
    InetAddress srcAdd2 = ipp2.src_ip;
    if(destAdd2 == destAdd && srcAdd2 == srcAdd ){
    if(ipp2 instanceof TCPPacket){
    TCPPacket tcp2 =(TCPPacket)ipp2;
    int destPort2 = tcp2.dst_port;
    int srcPort2 = tcp2.src_port;
    if(destPort2 == 4444 || destPort2 == 9996){

    System.out.println(srcAdd2 + " " + destAdd2 + " " +srcPort2 + " " + destPort2);
    }

    }
    }
    }
    }

    Default Re: keep ip address event

    What does "but can't run it" mean?
    Errors?
    Exceptions?
    Stack traces?

    Also, when posting code please use [code] tags [/code].
    Please do not ask for code as refusal often offends.

    Then I'd suggest adding in some more debugging statements to find out exactly where it is getting stuck.
    I can't follow the flow of that code as it stands with no formatting.
