NetBIOS / NBT


Overview
Overview

  • History

  • What is NetBIOS

  • What is NBT

  • Services Provided

    • Name Service

    • Session Service

    • Datagram Service


History
History

  • Developed by Sytek Inc. for IBM's PC-Network in 1983

  • Did not work over large scale wide spread networks

  • NBT(NetBIOS over TCP/IP) was invented to run on these large TCP/IP networks

  • It is described by

    • RFC 1001 to work over TCP/UDP

    • RFC 1002 to work on multiple platforms


What is netbios
What is NetBIOS

  • NetBIOS stands for Network Basic Input/Output System

  • NetBIOS allows applications on different computers to communicate over LANs

    • Currently uses TCP/IP

    • Gives each computer a NetBIOS name along with normal IP address


What is nbt
What is NBT

  • NBT is a protocol that allows legacy applications that rely on NetBIOS to be used on modern TCP/IP networks

  • NBT implements a Name Service that records all name registrations


Services provided by netbios and nbt
Services Provided by NetBIOS and NBT

  • NetBIOS provides three basic services:

    • NAME SERVICE

      • The name service provides name registration and resolution for clients

    • SESSION SERVICE

      • The session service provides connection-oriented communication

    • DATAGRAM SERVICE

      • The datagram service provides for a connectionless communication


Name service
Name Service

  • The length of names are 16 bytes

  • 16th byte commonly use for type

  • Operates on TCP or UDP port 137

  • Follows the packet structure of DNS

  • Services provided:

    • Add name – Registers a NetBIOS name

    • Add Group Name – Registers a NetBIOS group name

    • Delete Name – Un-registers a NetBIOS name

    • Find Name – Looks up a NetBIOS name


Session service
Session Service

  • Establishes a connection

  • Error detection and recovery

  • Operates on TCP port 139

  • Services Provided:

    • Call – Opens a session to a remote NetBIOS name

    • Listen – Listens for attempts to open sessions

    • Hangup – Closes a session

    • Send – Sends a packet to the computer on the other end

    • Send No Ack – Send, but does not require a ack

    • Receive – Waits for a packet to arrive


Datagram service
Datagram Service

  • Connectionless

  • Runs on UDP port 138

  • Services Provided:

    • Send Datagram – Sends a datagram to a remote host

    • Send Broadcast Datagram – Sends a datagram to the entire network

    • Receive Datagram – waits for a packet from a send datagram operation

    • Receive Broadcast Datagram - waits for a packet from a send broadcast datagram operation
