Batch deployment of machine execution command templates without public keys

Run the "www.2cto.com" script to copy the ip address of the master control machine to more than two machines (IP: 172.16.1.187 and 172.16.1.188) without using the public key: 172.16.1.199 directory/liang/ceshi. sh script (if there are more objective requirements here...
Run the "www.2cto.com" script to copy the ip address of the master control machine to more than two machines (IP: 172.16.1.187 and 172.16.1.188) without using the public key: 172.16.1.199 directory/liang/ceshi. sh script (if you have more requirements, follow these steps to expand it !) You can run the following script on the master control machine IP address: 172.16.1.199! Method 1: (continuous ip) vim bushu. sh #! /Usr/bin/empty CT-ffor {set I 187} {$ I <= 208} {incr I} {spawn ssh-l root 172.16.1. $ ishortct "* password:" sleep 1 send "123456 \ r" ### you can continue to extract keywords! Keep CT "root" send "scp root@172.16.1.199:/liang/ceshi. sh/liang/\ r" # Here is the command operation to be executed in batches! More operations can be similar and written! ### Note that if you connect to IoT platform for the first time, the system may prompt yes/no! If this is the first time, you have to add the following two lines: # Your CT "yes" # send "yes \ r" your CT "pasword: "send" 123456 \ r "wrong CT eof} Method 2: (discontinuous ip address) the above can be written as follows :#! /Usr/bin/login CT-fforeach ip {172.16.1.187172.16.1.188} {spawn ssh-l root $ ipshortct "* password: "sleep 1 send" 123456 \ r "### you can continue to extract keywords!
