配置两台Linux主机互信（suse11sp2版本）

1.分别登陆两台主机

#ssh-keygen

目的是简单地在/root下创建目录.ssh，当提示输入passphase时输入两次回车，将生成两个文件：

/root/.ssh/id_rsa
/root/.ssh/id_rsa.pub

2.测试，从一台ssh到另一台

#ssh 20.26.3.82

kaesrer:~/.ssh # ssh 20.26.3.82
Password:

3.

#scp /root/.ssh/id_rsa.pub [email protected]:/root/.ssh/authorized_keys

4.测试

kaesrer:~/.ssh # ssh 20.26.3.82
