Module negotiate 

NEGOTIATE ([MS-SMB2] §2.2.3).

Modules

caps

Capability bits (§2.2.3.2.5).

ctx_type

Negotiate context types (§2.2.3.1.2).

Structs

Context

One parsed negotiate context.

Request

Parsed SMB2 NEGOTIATE request.

Constants

DIALECT_202

Dialect numbers (§2.2.3.1.1). SMB 2.0.2 dialect revision.

DIALECT_210

SMB 2.1.0 dialect revision.

DIALECT_300

build_response_full

Build the NEGOTIATE response body (§2.2.3.1) — no security blob (clients initiate NTLMSSP in SESSION_SETUP).

parse_signing_algos

Parse a client SMB2_SIGNING_CAPABILITIES context (§2.2.3.1.7) into its advertised SigningAlgorithms list.

select_signing_algo

Select the signing algorithm: the client’s first that the server supports ([MS-SMB2] §3.3.5.4).
