[Mac] listen 포트 & pid 확인 방법, TCP/UDP 세션 확인 방법 본문
맥 환경에서,
잘모르는 프레임웍 이용한 서버 동작시,
특정프로그램 이용시,
내가 사용하는 것 외 데이터가 세어나가는지,
내가 모르는 포트를 열어놓은 프로세스가 있는지 (찾아서 kill하려고),
혹은 방화벽 제외 / NAT환경에서의 포트포워딩 정책에 SNAT, DNAT등에 포트 값을 알아내야 할 경우
lsof와 netstast과 다음과 같은 옵션으로 찾으면 된다.
(기타 : linux의 경우 netstat -anp|grep 포트번호 or LISTEN or EST등의 소켓 상태로 필터링해서 사용해왔음)
lsof (list open files) 이용시
$ sudo lsof -iTCP -sTCP:LISTEN -n -P
$ sudo lsof -iTCP -sTCP:LISTEN -n -P
