| | RFC 1001 (rfc1001) - Protocol standard for a NetBIOS service on a TCP/UDP |
 | | A NetBIOS Datagram is composed of the following protocol elements: - IP header of 20 bytes (minimum) - UDP header of 8 bytes - NetBIOS Datagram Header of 14 bytes - The NetBIOS Datagram data. | | | NetBIOS messages are sent by prepending the user data with a message header and sending the header and the user data over the TCP connection. | | | NetBIOS on other computer systems may present the NetBIOS services to programs using other interfaces. |

| | Netbios |
| | NetBIOS names can either be registered as UNIQUE, in other words only one owner, such as a computer's or user's name or they can be registered as a GROUP, where this refers to a group of computers or users such as a Workgroup or Domain. | | | The NetBIOS header is set to Byte 1 = 81h (session request), Byte 2 = 00h, Byte 3 = 00h and Byte 4 = 44h. | | | It must be noted though that NetBIOS is not a protocol but it does have a base of rules such as naming conventions - for the naming of computers, workgroups, domains, users and other services. |

| | Hacking FAQ and Information |
| | NetBIOS hacks are the worst kind, since they don't require you to have any hidden backdoor program running on your computer. | | | NetBIOS is meant to be used on local area networks, so machines on that network can share information. | | | Note that GRC will attempt to connect to your computer using NetBIOS - this is just to test whether your computer is vulnerable. |

| | NetBIOS protocol, netbeui over TCP, server message blocks |
| | NetBIOS, being effectively an interface rather than a protocol, requires a network protocol to carry its sessions across a network. | | | NetBIOS datagrams are connectionless and unreliable and can only manage messages up to 512 bytes in length. | | | This makes the NetBIOS frame shorter as the Session Number fields are now just one byte instead of the NetBIOS name fields which were 16 bytes fields. |

| | EHS Company - - Primer: An Overview of NetBIOS-Over-TCP/IP Name Resolution Services - |
| | The NetBIOS name you are querying for must match the name as registered by the system that owns it. | | | An m-node is a mixed node that uses broadcasted queries to find a node, and failing that, queries a known p-node name server for the address. | | | Several years ago, IBM developed NetBIOS with the goal of drawing up a network protocol that would work on small networks of PCs. |

| | NetBIOS |
| | NetBIOS is a program run on windoze b0xes and it is used for either a to identify remote networks or file and print sharing. | | | If you are on another chatting medium try to make a direct connection or send them an email with a reciept of reading attached so when they open it the receipt will return to you and inside the headers will be their IP or hostname. | | | # # Finally, non-printing characters can be embedded in mappings by # first surrounding the NetBIOS name in quotations, then using the # \0xnn notation to specify a hex value for a non-printing character. |

| | NetBEUI - Wikipedia, the free encyclopedia |
| | Sytek developed NetBIOS for IBM for the PC-Network program and was used by Microsoft for MS-NET in 1985. | | | To do so, an "Add Name Query" or "Add Group Name Query" packet is broadcast on the network. | | | NetBIOS Extended User Interface (NetBEUI, pronounced net-booey, also known as NetBIOS Frame, or NBF) is an unrouted network- and transport-level data protocol most commonly used as one of the layers of Microsoft Windows networking. |

| | File and Printer Sharing (NetBIOS) Fact and Fiction |
| | This is because computers running NetBIOS over TCP/IP with Scope ID are invisible to other computers that do not have the same Scope ID. | | | The real impact on your computer is insignificant. | | | In other words, if (for example) you have not actually configured any "shares," then there is no real security risk from File and Printer Sharing for Microsoft Networks being bound to TCP/IP. |

| | NetBIOS/NetBEUI (Linktionary term) |
| | The NetBIOS (Network Basic Input Output System) was designed by IBM and Sytek to support client/server computing in LAN environments. | | | Since you cannot build internetworks with NetBEUI, most organizations have moved to NetBIOS and Windows Sockets over TCP/IP. | | | According to the paper at the dtool Web site (see link on the related entries page), NetBEUI formalized the transport layer frame that was never standardized in NetBIOS. |

| | Name Resolution |
| | After checking address cache, a broadcast is sent, then the lmhost file is checked if broadcasting did not resolve the query. | | | If entries in this file contain the entry "#PRE", the value of that line is loaded into the NetBIOS name cache memory and broadcasts will not be used to resolve these host name to IP addresses. | | | #PRE - Preload the line information into memory (NetBIOS name cache). |

| | What is SMB, NetBIOS etc.? |
| | It turns out that there are advantages to using TCP/IP, IPX, or some other protocol as the underlying communication between computers. | | | If you open the "Network" configuration window in recent versions of Windows, you might have noticed that there is no option for "NetBIOS over TCP/IP". | | | If you do want the TCP/IP protocol, but not "NetBIOS over TCP/IP" (because you're worried about security), you should uncheck "Files and Printer Sharing" in the Bindings tab of the TCP/IP entry in Network Configuration. |

| | Network Basic Input/Output System - NetBIOS |
| | Short for Network Basic Input/Output System, NetBIOS was developed by IBM, Microsoft, and Sytek and is what allows software applications, commonly used on IBM compatible computers, communicate with network hardware, allowing data to be transmitted properly over a network. | | | If your network or computer has a firewall setup that blocks any of these ports it is likely warning messages will be received when your computer communicates with another computer that utilizes NetBIOS (for example: Microsoft Windows). | | | NetBIOS commonly communicates on ports 137, 138 and 139. |
