【问题描述】：

我在云端有 2 台机器。

172.31.2.102 = Ansible ec2 服务器 172.31.8.56 = ec2 主机

我曾经用私钥连接这两个服务器。甚至两台服务器都可以使用 pem 密钥通过 SSH 相互连接。 请查找连接日志：

ubuntu@ip-172-31-2-102:~$ ssh -i mkey.pem ec2-user@172.31.14.167
Last login: Thu Aug  6 07:08:11 2015 from ip-172-31-2-102.us-west-2.compute.internal

https://aws.amazon.com/amazon-linux-ami/2015.03-release-notes/
[ec2-user@ip-172-31-14-167 ~]$ ifconfig
eth0      Link encap:Ethernet  HWaddr 0A:67:A8:97:F9:29
          inet addr:172.31.14.167  Bcast:172.31.15.255  Mask:255.255.240.0

Ansible 使用 SSH 连接来连接主机。但是这次我的 ansible 机器（ubuntu 用户）无法连接到主机（ec2-user）

请查看以下调试日志
