Password encryption

if I change my password on two different servers, using the same string but the encrypted password in /etc/passwd look different.

If I copy an entry from one /etc/password to the other server. I can still log in to both servers using the same password. Only now both /etc/passwd entries are identical.

How is this possible?

They don't want people to be able to compare hashes like that. Otherwise, if an attacker got to the hashes, they could compare it to a list of known hashes -- which would speed up password bruteforcing tremendously.

In short, they mutate (salt) it a little to prevent people from doing exactly what you tried to do just now. Smilie
