  /etc/xinetd.d/ 에서 ssh파일 생성해서  설정을 하고 나서
 /etc/rc.d/init.d/xinetd restart
 하고 로그아웃 한 다음 아래와 같이 테스트 하는데 안되네요..
 [root@bada etc]# ssh localhost     ==> ssh -root localhost해도 마찬가지요..
warning: Authentication failed.
Disconnected; connection lost (Connection closed by remote host.).
[root@bada root]# sshd2 
sshd2: SSH Secure Shell 3.1.0 (non-commercial version) on i686-pc-linux-gnu
sshd2[11589]: WARNING: Host key pair is not specified, trying to use default 'hostkey'.
sshd2[11589]: FATAL: Creating listener failed: port 22 probably already in use!
  /etc/servies 에서 ssh가 port22 할당되어 있는건 확인 했거든요..
  
 안되는데 어찌해야하나요?
