我知道不建议这样做,但是是否有可能将用户的密码传递给scp?

我想通过scp复制一个文件,作为批处理作业的一部分,接收服务器当然需要密码,不,我不能轻易地将其更改为基于密钥的身份验证。

Make sure password authentication is enabled on the target server. If it runs Ubuntu, then open /etc/ssh/sshd_config on the server, find lines PasswordAuthentication=no and comment all them out (put # at the start of the line), save the file and run sudo systemctl restart ssh to apply the configuration. If there is no such line then you're done. Add -o PreferredAuthentications="password" to your scp command, e.g.: scp -o PreferredAuthentications="password" /path/to/file user@server:/destination/directory

我有一个简单的方法:

使用相同的scp cmd,因为您使用ssh密钥,即

scp -C -i <path_to打开sshkey> <'local file_path'> user@<ip_address_VM>: <'remote file_path'>

用于从本地传输文件到远程

但是不要提供正确的<path_to_opensshkey>,而是使用一些垃圾路径。由于错误的密钥路径,您将被要求输入密码,而不是你现在可以简单地通过密码来完成工作!

如果你观察到一个严格的主机密钥检查错误,那么使用-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null选项。

完整示例如下 sshpass -p "password" scp -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root@domain-name.com:/tmp/from/psoutput /tmp/to/psoutput

如果您从Windows连接到服务器,Putty版本的scp(“pscp”)允许您使用-pw参数传递密码。

这里的文档中提到了这一点。

您可以在unix/terminal上使用'expect'脚本

例如,创建'test。经验值:

#!/usr/bin/expect
        spawn scp  /usr/bin/file.txt root@<ServerLocation>:/home
        set pass "Your_Password"
        expect {
        password: {send "$pass\r"; exp_continue}
                  }

运行脚本

expect test.exp 

我希望这对你有所帮助。
