实验目的：在linux上通过ssh直接登录到windows系统上，不用密码

实验环境：在windows上安装cygwin，在linux 上通过ssh 连接到windows

          Windows ip  ：10.1.165.1   linux ip ： 10.1.151.111

配置前，由linux登录到windows需要密码

[yang@rac1 python]$ ssh -laaaa 10.1.165.1

aaaa@10.1.165.1's password:

aaaa@dfvkr-PC ~

$ dir

aaaa@dfvkr-PC ~

$ pwd

/home/aaaa

步骤：

1 在linux上通过ssh-keygen –t rsa 产生密钥

[yang@rac1 ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/yang/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/yang/.ssh/id_rsa.

Your public key has been saved in /home/yang/.ssh/id_rsa.pub.

The key fingerprint is:

58:d9:4d:ad:04:08:ae:f7:5d:15:fd:36:58:b3:79:a2 yang@rac1

在home/yang目录下产生.ssh，修改其属性

[yang@rac1 ~]$ chmod 755 .ssh

进入该文件夹，查看生成的文件

[yang@rac1 .ssh]$ ls

id_rsa  id_rsa.pub  known_hosts

其中id_rsa 为私钥，id_rsa.pub 为公钥。我们需要将公钥拷贝到windows系统中cygwin显示的家目录，我的是/home/aaaa ,在此文件夹下建立 .ssh文件夹。（一下是在windows系统下的操作）

aaaa@dfvkr-PC ~

$ mkdir .ssh

aaaa@dfvkr-PC ~

$ ls -al

total 26

drwxr-xr-x+ 1 aaaa None    0 Jul 18 11:27 .

drwxrwxrwt+ 1 aaaa root    0 Jul 17 19:52 ..

-rw-------  1 aaaa None  309 Jul 18 10:24 .bash_history

-rwxr-xr-x  1 aaaa None 1103 Jul 17 17:28 .bash_profile

-rwxr-xr-x  1 aaaa None 5663 Jul 17 17:28 .bashrc

-rwxr-xr-x  1 aaaa None 1461 Jul 17 17:28 .inputrc

-rwxr-xr-x  1 aaaa None  792 Jul 17 17:28 .profile

drwxr-xr-x+ 1 aaaa None    0 Jul 18 11:27 .ssh

-rw-r--r--  1 aaaa None  391 Jul 18 11:17 d:

然后拷贝linux上生成的公钥到.ssh目录下，并命名为authorized_keys

aaaa@dfvkr-PC ~

$ cd .ssh

aaaa@dfvkr-PC ~/.ssh

$ ls

authorized_keys

再次由linux登录到windows

[yang@rac1 python]$ ssh -laaaa 10.1.165.1
