안녕하세요.하나로ADSL Pro 외장형 RAS 사용자입니다.
 인터넷연결에대해서 여쭈어 볼려고 합니다.  리눅스는 래드헷 7.1입니다.
 인터넷에 연결을 하여 리눅스공부를해볼려고 했는데 에러가 나네요.

  이 스크립트는 /etc/rc.d/init.d/ras 에 있는 적혀 져 있는 스크립을 수정하여 나온것
 을 다시 기록하였슴니다.  그리고 물론 /etc/ras.conf에 제 id와 패수워드
 기록했습니다.
 
rpm -Uvh ras-3.2.2-1.noarch.rpm  이걸로 ras파일설치햇습니다.
 음 근데 이런 에러가 나네요.
