下不出现提示使用远程拷贝命令计划

把你的本地主机用户的ssh公匙文件写入到远程主机用户的~/.ssh/authorized_keys文件中,具体方法如下：

假设本地主机test1,远程主机test2

一，在test1主机里的用户

运行 ssh-keygen -t rsa

结果如下

Generating public/private rsa key pair.

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

Enter passphrase (empty for no passphrase):#回车

Enter same passphrase again:#回车

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

Your public key has been saved in /home/.username /.ssh/id_b.

The key fingerprint is:

38:25:c1:4d:5d:d3:89:bb:46:67:bf:52:af:c3:17:0c username@localhost

Generating RSA keys:

Key generation complete.

会在用户目录~/.ssh/产生两个文件，id_rsa，id_b

消费者也无从选择。最可怕的是 二，把id_b文件拷贝到test2主机的用户目录下

cat id_b ~/.ssh/authorized_keys

就可以了

这样test1主机的用户就可以通过ssh而不用密码登陆test2主机。
