ssh连不上

redware

以前装完debian3.1的基本系统后就能远程用ssh连上。昨天又装了一次基本系统，还特地看了看确实已经装了ssh的。结果现在远程连接时出现：
# ssh root@192.168.57.39
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
ed:4b:8d:19:34:74:11:ff:ef:ce:6d:f8:32:ea:dd:24.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
RSA host key for 192.168.57.39 has changed and you have requested strict checking.
Host key verification failed.
请问是怎么回事？以前装和现在装好像步骤上没什么区别吧。

将你本地的~/.ssh/的key去掉

谢谢！居然完全相同的安装，这个东东也变了。

à为Ï次安Å会§生不同的rsa和dsa key,所åÜï主机Í°安Å后，本地主机就要把£›know hosts keys删除掉
