Save the first column of the file host_password_user.txt below to ipaddr.txt, the second column to password.txt and the third column to user.txt
Code:
ipaddr1 password1 user1
ipaddr2 password2 user2
ipaddr3 password3 user3

then invoke the script change_passwd.sh below
Code:
#!/bin/bash

mapfile addr < ${1}
mapfile pass < ${2}
mapfile user < ${3}

for((i=0; i<${#addr[@]}; ++i)); do
     ssh ${addr[i]} "echo '${pass[i]}' | passwd --stdin '${user[i]}'"
done

this way
Code:
bash change_passwd.sh ipaddr.txt password.txt user.txt

I don't wonder your intelligence what the file host_password_user.txt stands for!
