Python 에서 Nmap 설치 하고 네트워크 검색(port)해보기(설치시 에러 해결)

Python 에서 Nmap 설치 하고 네트워크 검색해보기

 

현재 나는 윈도우 OS를 사용하고 파이썬 프로그래밍 툴로 Visual Studio를 사용한다. 이를 기초로 Nmap을 설치하고 동작 시켜볼 예정이다.

Nmap 설치

 

코드>>

import nmap
nm = nmap.PortScanner()
print(nm.scan('127.0.0.1', '22-443'))

 

위와 같이 단순한 코드를 동작 시켰다. 하지만 아래와 같은 에러메세지가 발생하였다.

AttributeError: module 'nmap' has no attribute 'PortScanner'

 

웹 검색결과 "pip install nmap" 으로 설치하는 것이 아닌 "pip install python-nmap" 으로 설치하라고 하여 다시 아래와 같이 설치 하였다.

하지만 위와 같이 다시 에러 메세지가 발생하였다. 그리고 동작이 안되었다.

 

결론적으로 말하자면 잘못설치된 nmap을 지우고 다시 python-nmap을 설치하여야 한다. (아래 코드 참조)

PS C:\Users\for> pip uninstall nmap
Uninstalling nmap-0.0.1:
  Would remove:
    c:\users\forgo\appdata\local\programs\python\python39\lib\site-packages\nmap-0.0.1.dist-info\*
    c:\users\forgo\appdata\local\programs\python\python39\lib\site-packages\nmap\*
  Would not remove (might be manually added):
    c:\users\forgo\appdata\local\programs\python\python39\lib\site-packages\nmap\test_nmap.py
Proceed (y/n)? y

Successfully installed python-nmap-0.6.4

 

그리고 코드를 실행시키니 결과가 아래와 같이 정상적으로 나왔다.

 

코드 결과>>

다음장부터는 nmap이용한 어플리케이션 제작을 해보겠다.
