主机密钥验证失败-亚马逊EC2
主机密钥验证失败-亚马逊EC2
提问于 2015-03-18 01:15:56
我正在使用win7和git bash以及一个亚马逊EC2实例。我尝试登录我的实例：
$ ssh -i f:mykey.pem ubuntu@ec2-52-10-**-**.us-west-2.compute.amazonaws.com
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
71:00:d7:d8:a------------------26.
Please contact your system administrator.
Add correct host key in /m/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /m/.ssh/known_hosts:27
ECDSA host key for ec2-52-10-**-**.us-west-2.compute.amazonaws.com has changed and you have request
ed strict checking.
Host key verification failed.以前以这种方式登录工作得很好，但这个问题是在我重启EC2实例后出现的。我怎么才能让它再次工作呢？
编辑：
$ ssh -i f:tproxy.pem ubuntu@ec2-52-10-**-**.us-west-2.compute.amazonaws.com
ssh: connect to host ec2-52-10-**-**.us-west-2.compute.amazonaws.com port 22: Bad file number
重试：
The authenticity of host 'ec2-52-10-**-**.us-west-2.compute.amazonaws.com (52.10.**-**)' can't be
established.
ECDSA key fingerprint is d6:c4:88:-----------fd:65.
Are you sure you want to continue connecting (yes/no)? y
Please type 'yes' or 'no': yes

Permission denied (publickey).我现在该怎么做？

键入以下命令以设置权限。将~/mykeypair.pem替换为密钥对私钥文件的位置和文件名。
chmod 400 ~/mykeypair.pem
在您的示例中，mykeypair.pem是tproxy.pem
我也面临着同样的问题，在把pem文件设为私有文件之后，这个问题就解决了。
