当我们尝试以下面的方式访问远程主机服务器时，它要求我输入密码。

]# ssh remotehost
Enter passphrase for key '/root/.ssh/id_rsa':
Enter passphrase for key '/root/.ssh/id_rsa':
Enter passphrase for key '/root/.ssh/id_rsa':
Password:

remotehost-1#

有没有办法在sshpass或expect等ssh命令中提供密码。

在连接remotehost之前，有一个.ssh / config文件可以访问2个jumphost。

我们可以在提示时执行可以预期/提供密码的内容，然后我们会登录。

以下是我们正在尝试但不起作用的内容。它给出了密码短语3次，但是当输入最后一个密码时，它就会出现，并且本地机器中没有创建文件。

#!/usr/bin/env expect
set timeout 10

spawn ssh ip < ./ai.py >> stinfo_2017.txt
expect "Enter passphrase for key '/root/.ssh/id_rsa':"
send "12345\r"
expect "Enter passphrase for key '/root/.ssh/id_rsa':"
send "12345\r"
expect "Enter passphrase for key '/root/.ssh/id_rsa':"
send "12345\r"
expect "Password:"
send "54321\r"
interact

运行脚本时，输出就是这样。

[root@centseven ~]# ./directconnect
spawn ssh ip < ./ai.py >> stinfo_2017.txt
Enter passphrase for key '/root/.ssh/id_rsa':
Enter passphrase for key '/root/.ssh/id_rsa':
Enter passphrase for key '/root/.ssh/id_rsa':
Password: 
zsh: no such file or directory: ./ai.py
Killed by signal 1.
Killed by signal 1.
[root@centseven ~]#

脚本未在远程服务器上执行，因此没有创建文件stinfo_2017.txt。

当我们手动运行它时，它会创建一个文件。

产卵线出现问题。

#!/usr/bin/env expect
set timeout 10

spawn sc -h "ssh ip < ./ai.py >> stinfo_2017.txt"
expect "Enter passphrase for key '/root/.ssh/id_rsa':"
send "12345\r"
expect "Enter passphrase for key '/root/.ssh/id_rsa':"
send "12345\r"
expect "Enter passphrase for key '/root/.ssh/id_rsa':"
send "12345\r"
expect "Password:"
send "54321\r"
