Examples of org.jnetpcap.protocol.tcpip.Tcp.calculateChecksum()

org.jnetpcap.protocol.tcpip.Tcp.calculateChecksum()
Calculates a checksum using protocol specification for a header. Checksums for partial headers or fragmented packets (unless the protocol alows it) are not calculated. @return header's calculated checksum


    ip.destination(dst.getAddress());
    ip.source(src.getAddress());


    ip.checksum(ip.calculateChecksum());
    tcp.checksum(tcp.calculateChecksum());
    packet.scan(Ethernet.ID);


    System.out.println(packet);
    List<PcapIf> alldevs = new ArrayList<PcapIf>(); // Will be filled with NICs
    StringBuilder errbuf = new StringBuilder(); // For any error msgs
