sequence_number: u16

body: Vec<u8>

Implementations

impl ICMPPacket

pub fn echo_request( identifier: u16, sequence_number: u16, body: Vec<u8>, src: u32, dst: u32, ttl: u8, info_url: &str, ) -> Vec<u8>

Create a basic ICMPv4 ECHO_REQUEST (8.0) packet with checksum.

Arguments

• ‘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

• ‘info_url’ - the URL to be added to the packet payload (e.g., opt-out URL)

pub fn echo_request_v6( identifier: u16, sequence_number: u16, body: Vec<u8>, src: u128, dst: u128, hop_limit: u8, info_url: &str, ) -> Vec<u8>

Create an ICMPv6 echo request packet with checksum

Arguments

• ‘identifier’ - the identifier for this packet

• ‘sequence_number’ - the sequence number for this packet

• ‘body’ - the payload of the packet

• ‘src’ - the source address of the packet

• ‘dst’ - the destination address of the packet

• ‘hop_limit’ - the hop limit (TTL) of the packet

• ‘info_url’ - URL encoded in packet payload (e.g., opt-out URL)

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
