ReadTNSDataNSN reads a TNSDataNSN packet from a stream pointing to the start of the NSN data.

ReadTNSRedirect reads a TNSRedirect packet from the stream, which should point to the first byte after the TNSHeader.

ReadTNSRefuse reads a TNSRefuse packet from the stream, which should point to the first byte after the TNSHeader.

ReadTNSResend reads a TNSResend packet from the reader, which should point to the first byte after the end of the header -- so in this case, it reads nothing and returns an empty TNSResend{} instance.

RegisterModule registers the zgrab2 module.

DataIDNSN identifies a Native Security Negotiation data payload.

NSNValueTypeVersion identifies a 32-bit ReleaseVersion value.

PacketTypeAbort identifies an Abort packet.

PacketTypeAccept identifies an Accept packet (the server's response to a Connect packet, contains some server configuration flags).

PacketTypeAcknowledge identifies an Acknowledge packet.

PacketTypeAttention identifies an Attention packet.

PacketTypeConnect identifies a Connect packet (first packet sent by the client, containing the connect descriptor).

PacketTypeControl identifies a Control packet.

PacketTypeData identifies a Data packet.

PacketTypeMarker identifies a Marker packet.

PacketTypeNull identifies a Null packet.

PacketTypeRedirect idenfies a Redirect packet.

PacketTypeRefuse identifies a Refuse packet.

PacketTypeResend identifies a Resend packet.

TNSMode12c uses the newer TNSHeader format, with 32-bit lengths and no PacketChecksum.

TNSModeOld uses the pre-12c format TNSHeader, with 16-bit lengths.

ErrBufferTooSmall is returned when the caller provides a buffer that is too small for the required data.

ErrInvalidData is returned when the server returns syntactically-invalid (or very unlikely / problematic) data.

ErrInvalidInput is returned when user-supplied data is not valid.

ErrUnexpectedResponse is returned when the server returns a valid TNS response but it is not the expected type.

Connection holds the state for a scan connection to the Oracle server.

DescriptorEntry is a simple key-value pair representing a single primitive value in the descriptor string.

Flags holds the command-line configuration for the HTTP scan module.

HandshakeLog gives the results of the initial connection handshake in a form suitable for zgrab2 output.

Module implements the zgrab2.Module interface.

NSNService is an individual "packet" inside the NSN data payload; it consists in an identifier and a list of values or "sub-packets" giving configuration settings for that service type.

NSNValue represents a single value or "sub-packet" within an NSNService.

Scanner implements the zgrab2.Scanner interface.

ScanResults instances are returned by the module's Scan function.

TNSAccept is the server's response to a successful TNSConnect request from the client.

TNSConnect is sent by the client to request a connection with the server.

TNSData is the packet type used to send (more or less) arbitrary data between client and server.

TNSDataNSN represents the decoded body of a TNSData packet for a Native Security Negotiation payload.

TNSDriver abstracts the bottom-level TNS packet encoding.

TNSHeader is the 8-byte header that precedes all TNS packets.

TNSPacket is a TNSHeader + a body.

TNSRedirect is returned by the server in response to a TNSConnect when it needs to direct the caller elsewhere.

TNSRefuse is returned by the server when an error occurs (for instance, an invalid connect descriptor).

TNSResend is empty -- the entire packet is just a header with a type of PacketTypeResend (0x0b == 11).

TNSPacketBody is the interface for the "body" of a TNSPacket (that is, everything after the header).
