Detailed Description

Implements common ICMP packet building routines and ICMP checksum.

Implements code common to all ICMP services, such as checksum and packet preparation

This is an abstract base class, a building block for any ICMP-based service.

Definition at line 31 of file ICMP.h.

Member Function Documentation

void ICMP::calcICMPChecksum ( )

protected

Calculates the ICMP checksum and populates the checksum field in the ICMP header.

If receiving, calculating the checksum sets packet.icmp.checksum to zero if the packet had no checksum errors.

Definition at line 59 of file ICMP.cpp.

bool ICMP::loadAll ( )

protected

Loads the entire ICMP packet into memory.

Returns: true if checksum is correct, false otherwise. The packet contents are nevertheless loaded into the packet buffer

Definition at line 40 of file ICMP.cpp.

virtual bool ICMP::onICMPMessage ( )

protectedpure virtual

void ICMP::sendICMPPacket	(	const IPAddress &	targetIP,
		uint16_t	dataLength
	)

protected

Sends an ICMP packet

Parameters

targetIP	Where to send the ICMP packet
dataLength	ICMP payload length
