CentOS ssh 호스트 키 변경

[root@theingka ~]# ls -l /etc/ssh/ssh_host_* 
-rw-------. 1 root root  668 Nov 21  2011 /etc/ssh/ssh_host_dsa_key
-rw-r--r--. 1 root root  590 Nov 21  2011 /etc/ssh/ssh_host_dsa_key.pub
-rw-------. 1 root root  963 Nov 21  2011 /etc/ssh/ssh_host_key
-rw-r--r--. 1 root root  627 Nov 21  2011 /etc/ssh/ssh_host_key.pub
-rw-------. 1 root root 1675 Nov 21  2011 /etc/ssh/ssh_host_rsa_key
-rw-r--r--. 1 root root  382 Nov 21  2011 /etc/ssh/ssh_host_rsa_key.pu

[root@theingka ~]#rm /etc/ssh/ssh_host_* 
[root@theingka ~]#ssh-keygen --A 

[root@theingka ssh]# service sshd restart
Stopping sshd: [  OK  ]
Generating SSH1 RSA host key: [  OK  ]
Generating SSH2 RSA host key: [  OK  ]
Generating SSH2 DSA host key: [  OK  ]
Starting sshd: [  OK  ]

이렇게 설정하면 새로운 호스트키 생성 끝 ~
