The authenticity of host '<host>' can't be established.

软件环境

Client：Mac OS X

Server：Cent OS 6.5

问题描述

修改/etc/hosts的Server名称之后ssh登陆出现如下信息：

localhost:~ Bob$ ssh root@www.vm.com

The authenticity of host 'www.vm.com (10.211.55.4)' can't be established.

RSA key fingerprint is 75:b4:45:24:04:71:b9:64:5e:fc:58:8a:7d:14:ff:c0.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'www.vm.com' (RSA) to the list of known hosts.

解决方案

由于是内网通信，所以不存在安全问题，所以去掉登录时主机密钥验证即可

localhost:~ Bob$ ssh  -o StrictHostKeyChecking=no www.vm.com
