Module caracat::builder

source ·
Expand description

Functions for building probe packets.

These functions are meant to be called in order, from the lowermost layer to the uppermost layer.

Examples

To keep this example self-contained we use empty MAC and IP addresses. Use crate::neighbors to get the gateway MAC address .

use std::net::Ipv4Addr;
use pnet::util::MacAddr;
use caracat::builder::{build_ethernet, build_icmp, build_ipv4, Packet};
use caracat::models::{L2, L3, L4};

let mut buffer = [0u8; 65535];
let mut packet = Packet::new(&mut buffer, L2::Ethernet, L3::IPv4, L4::ICMP, 2);

build_ethernet(&mut packet, MacAddr::zero(), MacAddr::zero());
build_ipv4(&mut packet, Ipv4Addr::UNSPECIFIED, Ipv4Addr::UNSPECIFIED, 32, 42);
build_icmp(&mut packet, 42, 4242);

println!("{:?}", packet.l2());

Structs

  • Packet
    A Packet holds pointers to the L2/L3/L4 layers over a buffer.
