    NAME

    "NetPacket::ICMP" - Assemble and disassemble ICMP (Internet Control
    Message Protocol) packets. 
     
    

    SYNOPSIS

      use NetPacket::ICMP;
    
    

      $icmp_obj = NetPacket::ICMP->decode($raw_pkt);
      $icmp_pkt = NetPacket::ICMP->encode();
      $icmp_data = NetPacket::ICMP::strip($raw_pkt);
    
    
     

    DESCRIPTION

    "NetPacket::ICMP" provides a set of routines for assembling and disassembling packets using ICMP (Internet Control Message Protocol).  

    Methods

    NetPacket::ICMP->decode([RAW PACKET])
    Decode the raw packet data given and return an object containing instance data. This method will quite happily decode garbage input. It is the responsibility of the programmer to ensure valid packet data is passed to this method.
    NetPacket::ICMP->encode()
    Return an ICMP packet encoded with the instance data specified.
     

    Functions

    NetPacket::ICMP::strip([RAW PACKET])
    Return the encapsulated data (or payload) contained in the ICMP packet.
     

    Instance data

    The instance data for the "NetPacket::ICMP" object consists of the following fields.
    type
    The ICMP message type of this packet.
    code
    The ICMP message code of this packet.
    cksum
    The checksum for this packet.
    data
    The encapsulated data (payload) for this packet.
