[태그:] nmblookup

외부 단말의 NetBIOS 이름을 찾아보고 싶었다. RHEL OS 에서는 nmblookup 과 nbtscan 이라는 명령어로 확인 할 수 있다.

1. nmblookup

samba-client 패키지에 포함되어 있다.

~]$ sudo dnf install samba-client

~]$ nmblookup -A 192.168.2.123
Looking up status of 192.168.2.123
        MACBOOKPRO-212C <00> -         H <ACTIVE> 

        MAC Address = BC-D0-74-5F-21-2C

2. nbtscan

nbtscan 은 epel 저장소에 있는 패키지이다. epel 저장소를 활성화 후 ntbscan 패키지 설치하면 된다.

]$ sudo dnf install -y epel-release
...
]$ sudo dnf install -y nbtscan

]# nbtscan 192.168.2.123
Doing NBT name scan for addresses from 192.168.2.123

개인적으로 nbtscan을 선호한다.
