How to make ssh receive the password from stdin

Question

How can you make SSH read the password from stdin, which it doesn't do by default?

Answer 1

FreeBSD mailing list recommends the expect library.

If you need a programmatic ssh login, you really ought to be using public key logins, however -- obviously there are a lot fewer security holes this way as compared to using an external library to pass a password through stdin.

Answer 2

You can't with most SSH clients. You can work around it with by using SSH API's, like Paramiko for Python. Be careful not to overrule all security policies.
