netbios简介:
IBM公司开发,主要用于数十台计算机的小型局域网。该协议是一种在局域网上的程序可以使用的应用程序编程接口(API),为程序提供了请求低级服务的同一的命令集,作用是为了给局域网提供网络以及其他特殊功能。
系统可以利用WINS服务、广播及Lmhost文件等多种模式将NetBIOS名-——特指基于NETBIOS协议获得计算机名称——解析为相应IP地址,实现信息通讯,所以在局域网内部使用NetBIOS协议可以方便地实现消息通信及资源的共享。

NBTscan version 1.5.1. Copyright (C) 1999-2003 Alla Bezroutchko.
This is a free software and it comes with absolutely no warranty.
You can use, distribute and modify it under terms of GNU GPL.

Usage:
nbtscan [-v] [-d] [-e] [-l] [-t timeout] [-b bandwidth] [-r] [-q] [-s separator] [-m
retransmits] (-f filename)|(<scan_range>)
-v verbose output. Print all names received

from each host

-d dump packets. Print whole packet contents.

-e Format output in /etc/hosts format.
-l Format output in lmhosts format.
Cannot be used with -v, -s or -h options.
-t timeout wait timeout milliseconds for response.

Default 1000.

-b bandwidth Output throttling. Slow down output
so that it uses no more that bandwidth bps.
Useful on slow links, so that ougoing queries
don't get dropped.

-r use local port 137 for scans. Win95 boxes

respond to this only.
You need to be root to use this option on Unix.

-q Suppress banners and error messages,
-s separator Script-friendly output. Don't print

column and record headers, separate fields with separator.

-h Print human-readable names for services.

Can only be used with -v option.
-m retransmits Number of retransmits. Default 0.
-f filename Take IP addresses to scan from file filename.
-f - makes nbtscan take IP addresses from stdin.
<scan_range> what to scan. Can either be single IP

like 192.168.1.1 or
range of addresses in one of two forms:
xxx.xxx.xxx.xxx/xx or xxx.xxx.xxx.xxx-xxx.

Examples:
nbtscan -r 192.168.1.0/24
Scans the whole C-class network.
nbtscan 192.168.1.25-137
Scans a range from 192.168.1.25 to 192.168.1.137
nbtscan -v -s : 192.168.1.0/24
Scans C-class network. Prints results in script-friendly
format using colon as field separator.
Produces output like that:
192.168.0.1:NT_SERVER:00U
192.168.0.1:MY_DOMAIN:00G

192.168.0.1:ADMINISTRATOR:03U
192.168.0.2:OTHER_BOX:00U
...
nbtscan -f iplist
Scans IP addresses specified in file iplist.
