以前维护测试环境，经常遇到某一个测试或者开发跑压测，乱改数据，乱改配置等等。。总之最终需要我去把环境恢复好，最好不过的是再把这个人给抓出来。。之前是知道nbtstat基本可以根据IP查出对于的netbios名字，这个就能和工号对应起来了。
今天发现linux下其实有个类似的命令，netscan，而且还能批量扫描，更为强大。具体的使用man一下就行。
“Human-readable service names” (-h) option cannot be used without verbose (-v) option.
Usage:
nbtscan [-v] [-d] [-e] [-l] [-t timeout] [-b bandwidth] [-r] [-q] [-s separator] [-m retransmits] (-f filename)|(
-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.
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.
