An ICMP Packet (ping packet) https://en.wikipedia.org/wiki/Internet_Control_Message_Protocol#header_rest

Fields

icmp_type: u8

code: u8

checksum: u16

icmp_identifier: u16

sequence_number: u16

payload: Vec<u8>

Implementations

impl ICMPPacket

pub fn echo_request( icmp_identifier: u16, sequence_number: u16, body: Vec<u8>, src: &Address, dst: &Address, ttl: u8, ) -> Vec<u8>

Create a basic ICMP ECHO_REQUEST (8.0) packet with checksum.

Arguments

• icmp_identifier - the identifier for the ICMP header
• sequence_number - the sequence number for the ICMP header
• body - the ICMP payload
• src - the source address of the packet
• dst - the destination address of the packet
• ttl - the time to live of the packet

pub(crate) fn calc_checksum(buffer: &[u8]) -> u16

Calculate the ICMP Checksum.

This calculation covers the entire ICMP message (16-bit one’s complement). Works for both ICMPv4 and ICMPv6
