## NetBios Name Service
|
||
|
||
**NetBIOS名称服务**在其中扮演着至关重要的角色，涉及各种服务，如**名称注册和解析**、**数据报分发**和**会话服务**，为每项服务利用特定端口。
|
||
|
||
[来自维基百科](https://en.wikipedia.org/wiki/NetBIOS_over_TCP/IP):
|
||
|
||
* 用于名称注册和解析的名称服务（端口：137/udp和137/tcp）。
|
||
* 用于无连接通信的数据报分发服务（端口：138/udp）。
|
||
* 用于面向连接通信的会话服务（端口：139/tcp）。
|
||
|
||
### 名称服务
|
||
|
||
为了使设备参与NetBIOS网络，它必须具有唯一名称。这是通过**广播过程**实现的，其中发送一个“名称查询”数据包。如果没有收到异议，则该名称被视为可用。或者，可以直接查询**名称服务服务器**以检查名称的可用性或将名称解析为IP地址。工具如`nmblookup`、`nbtscan`和`nmap`被用于枚举NetBIOS服务，揭示服务器名称和MAC地址。
|
||
```bash
|
||
PORT STATE SERVICE VERSION
|
||
137/udp open netbios-ns Samba nmbd netbios-ns (workgroup: WORKGROUP)
|
||
```
|
||
通过枚举 NetBIOS 服务，您可以获取服务器正在使用的名称和服务器的 MAC 地址。
|
||
```bash
|
||
nmblookup -A <IP>
|
||
nbtscan <IP>/30
|
||
sudo nmap -sU -sV -T4 --script nbstat.nse -p137 -Pn -n <IP>
|
||
```
|
||
### 数据报分发服务
|
||
|
||
NetBIOS 数据报允许通过 UDP 进行无连接通信，支持直接消息传递或广播到所有网络名称。此服务使用端口 **138/udp**。
|
||
```bash
|
||
PORT STATE SERVICE VERSION
|
||
138/udp open|filtered netbios-dgm
|
||
```
|
||
### Session Service
|
||
|
||
对于面向连接的交互，**Session Service** 通过 **139/tcp** 端口利用 **TCP** 连接促进两个设备之间的对话。会话以 "Session Request" 数据包开始，并可以根据响应建立。该服务支持更大的消息、错误检测和恢复，TCP 处理流量控制和数据包重传。
|
||
|
||
会话中的数据传输涉及 **Session Message packets**，会话通过关闭 TCP 连接来终止。
|
||
|
||
这些服务是 **NetBIOS** 功能的核心，能够在网络中实现高效的通信和资源共享。有关 TCP 和 IP 协议的更多信息，请参阅它们各自的 [TCP Wikipedia](https://en.wikipedia.org/wiki/Transmission_Control_Protocol) 和 [IP Wikipedia](https://en.wikipedia.org/wiki/Internet_Protocol) 页面。
|
||
```bash
|
||
PORT STATE SERVICE VERSION
|
||
139/tcp open netbios-ssn Microsoft Windows netbios-ssn
|
||
```
|
||

## HackTricks 自动命令
|
||
```
|
||
Protocol_Name: Netbios #Protocol Abbreviation if there is one.
|
||
Port_Number: 137,138,139 #Comma separated if there is more than one.
|
||
Protocol_Description: Netbios #Protocol Abbreviation Spelled out
|
||
|
||
Entry_1:
|
||
Name: Notes
|
||
Description: Notes for NetBios
|
||
Note: |
|
||
Name service for name registration and resolution (ports: 137/udp and 137/tcp).
|
||
Datagram distribution service for connectionless communication (port: 138/udp).
|
||
Session service for connection-oriented communication (port: 139/tcp).
|
||
|
||
For a device to participate in a NetBIOS network, it must have a unique name. This is achieved through a broadcast process where a "Name Query" packet is sent. If no objections are received, the name is considered available. Alternatively, a Name Service server can be queried directly to check for name availability or to resolve a name to an IP address.
