서버 진단을 받아보니깐.. 포트가 많이 열려있더라고 하더군요.. 어디서 줏어 들은 얘기론.. /etc/services에 있는 걸 필요한거 빼고 주석처리 한담에 inetd를 restart하믄 댄다구 하던데.. (맞나? -_-;;) 글구.. 물론 inetd.conf 파일도 바꿔야죠, restart하기 전에.. 제가 하고 싶은건, ftp,telnet,sendmail,pop3,web/dns서버로 쓰려고 하는데.. 포트가 많은건지.. 뭐가 몬지 잘 모르겠더군요.. services 목록이 하도 길어서.. 어딜 어떻게 고쳐야 하는지 아시는 분.. 좀 도와주시면 고맙겠습니다.. ㅠ_ㅠ 현재 고쳐놓은 상탠데.. 맞는지도 모르겠고.. 좀 봐주세요~ /etc/services # $Id: services,v 1.4 2000/01/23 21:03:36 notting Exp $ # # Network services, Internet style # # Note that it is presently the policy of IANA to assign a single well-known # port number for both TCP and UDP; hence, most entries here have two entries # even if the protocol doesn't support UDP operations. # Updated from RFC 1700, ``Assigned Numbers'' (October 1994).
