https://blog.csdn.net/wang1144/article/details/51731059

问题

每次ssh 进入一台新机器都会跳出如下的提示:

1
2
3

The authenticity of host '111.222.333.444 (111.222.333.444)' can't be established.
RSA key fingerprint is f3:cf:58:ae:71:0b:c8:04:6f:34:a3:b2:e4:1e:0c:8b.
Are you sure you want to continue connecting (yes/no)?

解决方法

  1. 加入一个参数：
1

ssh -o "StrictHostKeyChecking no" user@host

2.修改配置文件

在文件/etc/ssh/ssh_config(全局)或者~/.ssh/config(某用户)开头加入以下内容:

1
2
3
4
5
6
7
8

Host 192.168.0.*
	StrictHostKeyChecking no
	UserKnownHostsFile=/dev/null
or

Host *
	StrictHostKeyChecking no
	UserKnownHostsFile=/dev/null
