finger 실습을 하고 싶은데
문서에는 /etc/xinetdd/finger 파일 수정하라고 하는데 없다.
[root@centos etc]# ls /etc/xinetdd/finger
ls: cannot access /etc/xinetdd/finger: 그런 파일이나 디렉터리가 없습니다
그냥 막무가내로 설치하고 확인해보았다.

여전히 finger는 없다.

finger-server 를 설치한 것 같은데 이상한걸..
/etc/xinetd.d/finger 가 없다. 문제가 있다고 ABRT 알림이 온것일까?
재부팅을 해보자.
ACPI 종료도 안된다.
