Struct RelayConn 

pub struct RelayConn { /* private fields */ }

One inbound SMB client being relayed: instead of answering the NTLM challenge with our own fixed value (capture), we hand the victim’s Type1 out to the caller, relay back the target’s Type2, and surrender the victim’s Type3 — so the caller can complete an authenticated session to a third-party target as the victim.

Implementations

impl RelayConn

pub fn new(stream: TcpStream) -> Self

pub async fn recv_type1(&mut self) -> Result<Vec<u8>>

Handle NEGOTIATE and the first SESSION_SETUP; return the victim’s NTLM Type1.

pub async fn send_challenge(&mut self, type2: &[u8]) -> Result<()>

Relay the target’s Type2 challenge back to the victim.

pub async fn recv_type3(&mut self) -> Result<Vec<u8>>

Receive the victim’s Type3 (computed over the target’s challenge).

pub async fn listen(addr: &str) -> Result<TcpListener>

Bind a listener for relaying; returns accepted RelayConns via the closure.
