How to enter ssh password using bash?
提问by Prostak
Everyday I am connecting to a server through ssh. I go through this routine:
我每天都通过 ssh 连接到服务器。我经历了这个例程：
IC001:Desktop user$ ssh [email protected]
[email protected]'s password:
Last login: Tue Jun 4 10:09:01 2013 from 0.0.0.0
$
I would like to automate this process and create a bash script to do it for me. I don't care about security and okay to store my password openly in the script. I am also okay for it to get typed openly on the screen while the script gets executed. So I've created this:
我想自动化这个过程并创建一个 bash 脚本来为我做这件事。我不关心安全性，可以在脚本中公开存储我的密码。我也可以在脚本执行时在屏幕上公开输入它。所以我创建了这个：
#!/bin/bash
ssh [email protected]
echo mypassword
But it doesn't work. I've also tried sendinstead of echo, but it also didn't work. Please advise if it is possible to do.
但它不起作用。我也试过send代替echo，但它也没有奏效。请告知是否可行。

Double check if you are not able to use keys.
仔细检查您是否无法使用密钥。
Otherwise use expect:
否则使用期望：
#!/usr/bin/expect -f
spawn ssh [email protected]
expect "assword:"
send "mypassword\r"
interact

Create a new keypair: (go with the defaults)
创建一个新的密钥对：（使用默认值）
ssh-keygen
Copy the public key to the server: (password for the last time)
将公钥复制到服务器：（最后一次的密码）
ssh-copy-id [email protected]
From now on the server should recognize your key and not ask you for the password anymore:
从现在开始，服务器应该识别您的密钥并且不再要求您输入密码：
ssh [email protected]
