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(params...); # Not implemented
$icmp_data = NetPacket::ICMP::strip($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::IGMP->encode(param => value)
-
Return an IGMP packet encoded with the instance data specified. Not implemented.
Functions
NetPacket::IGMP::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
