pid 8282 커맨드 whois 로 나오는데 이게 어떤 데몬인지는 모르시는지요??

참고로 홈페이지에 사람은 많지 않습니다. centos 를 쓰고 업체에서 설치해준후 아무것도 건드리지

않았습니다.

일단 8383 pid를 종료시켰어요 무엇인지는 잘 모르겠는데 pid번호로 무슨 프로그램인지 검색하려면 어떻게 해야할까요?

/proc/pid번호/ 경로로 찾아가시면, 해당 프로세스 번호로 실행된 정보들을 이곳에서 알수있습니다.

시스템에 특이한 프로세스는 올라와 있지 않은데, whois 라는 명령어의 부하가 높네요.

저 부분을 찾아보시는게 좋겠어요.
