[질문] wu-ftpd 접근권한에 대해 질문 좀....

지금 wu-ftpd 어찌어찌 겨우겨우 해서 동작은 되게 해놨는데요...

이제 접근권한만 하면 다될것 같은데 이게 잘 안되네요;;;

메뉴얼을 봐도 무슨 소린지 이해도 잘 안가고;;;

지금 할려는게 passwd에 있는 특정 유저의 홈디렉토리를 /jffs2/config로 해놓는데까지는

성공했는데 이 유저가 저상위 디렉토리 이상 접근을 못하게 하고싶습니다...realuser, guestuser

이런 얘기들 막 나오는데 이해가 잘 안되네요...;

ftpaccess파일의 어느부분을 손봐야 하는지 지적좀 해주셔요;
