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
