配置兩臺Linux主機互信（suse11sp2版本）

1.分別登陸兩臺主機

#ssh-keygen

目的是簡單地在/root下創建目錄.ssh，當提示輸入passphase時輸入兩次回車，將生成兩個文件：

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

2.測試，從一臺ssh到另一臺

#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.測試

kaesrer:~/.ssh # ssh 20.26.3.82
