SSH密码验证绕过

2019独角兽企业重金招聘Python工程师标准>>> html

导读	常常咱们使用脚本登入服务器的时候，若是使用ssh 命令，常常会提示密码输入，咱们不得不手动输入密码，由于ssh 没有密码的选项。为了能绕过交互式验证，咱们使用sshpass命令解决这个问题：

1. 安装linux

➜  Desktop sudo yum install sshpass
[sudo] password for xuyaowen: 
Last metadata expiration check: 0:04:22 ago on Mon 02 Jul 2018 11:25:32 AM CST.
Package sshpass-1.06-5.fc28.x86_64 is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!

检查是否安装服务器

[root@yaowenxu Desktop]# rpm -qa sshpass
sshpass-1.06-5.fc28.x86_64

2. 查看 sshpass 命令帮助, 也可使用 man sshpassssh

View Codeide

[root@yaowenxu Desktop]# sshpass
Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
   -f filename   Take password to use from file
   -d number     Use number as file descriptor for getting password
   -p password   Provide password as argument (security unwise)
   -e            Password is passed as env-var "SSHPASS"
   With no parameters - password will be taken from stdin

   -P prompt     Which string should sshpass search for to detect a password prompt
   -v            Be verbose about what you're doing
   -h            Show help (this screen)
   -V            Print version information
At most one of -f, -d, -p or -e should be used

3. 使用密码验证登陆this

➜  ~ sshpass -p 123 ssh root@10.66.65.15

4. ssh 第一次登陆提示问题使用：google

ssh -o StrictHostKeyChecking=no.net

来解决orm

➜  Desktop sshpass  -p 123 ssh -o StrictHostKeyChecking=no root@10.66.8.142
Warning: Permanently added '10.66.8.142' (ECDSA) to the list of known hosts.

5. 优缺点htm

优势：快速，便捷

缺点：密码明文暴露，可使用 history 命令查找到
