自动化SSH不使用公共密钥认证或预期（1） [英] Automate SSH without using public key authentication or expect(1)

问题描述

有没有办法通过一个密码来自动SSH协议。我想自动ssh到服务器不的使用公钥认证或期望的脚本，通过某种方式让ssh来阅读从标准输入或文件的密码。

Is there a way to pass a password to ssh automatically. I would like to automatically ssh to a server without using public key authentication or expect scripts, by somehow getting ssh to read the password from stdin or a file.

它是这个样子的原因是，我想我的备份文件，使用运行作为cron作业的rsync / SSH服务器。该服务器后装入我的主目录的 它验证了我，因此，使用公钥验证不起作用，因为的〜/ .ssh不适后才登录成功。期待（1）是不可能的，因为我想运行它作为一个cron作业，而且由于cron作业没有终端下运行预期的组合/ SSH是行不通的。我没有到该服务器的root访问权限，这将是很难得到管理员做任何改变的东西在那里工作的方式。

The reason it has to be that way is that I would like to backup my files to a server using rsync/ssh running as a cron job. This server mounts my home directory after it authenticates me, so using public key authentication does not work since ~/.ssh isn't available until after the login is successful. expect(1) is out of the question because I would like to run it as a cron job, and since cron jobs don't run under a terminal the combination of expect/ssh just doesn't work. I do not have root access to that server, and it would be difficult to get the admins to make any changes to the way things work there.

推荐答案

使用 sshpass 。

例如，当密码是在的password.txt 文件：

For example, when password is in password.txt file:

sshpass -fpassword.txt ssh username@hostname
