Script to change password on linux servers over ssh

Question

We have a number of Red Hat linux servers in our IT environment. I am being asked by my team members to write a script (preferably shell script) to change a user\'s password

Answer 1

Building on squashbuff's example, I tried the following, which worked well for me:

#!/bin/bash
for server in `cat hostlist`; do
echo $server;
ssh username@$server 'passwd <<EOF
old_password
new_password
new_password
EOF';
done

Security wise, Could be improved to take input without echoing to the screen OR saving the plaintext to disk.
