Re: SSH Unexpectedly Not Prompting for Password



You will probably find that you have used "teddys" public key in each of
bears ~/.ssh/authorized_keys files and have teddys corresponding id_rsa
(the private key file) in each of the ~/.ssh/ directories.

the id_rsa.pub file should have no bearing on anything, as this is simply
the text that is supposed to be added to the authorized_keys file.

I'm guessing you just copied everything, including the private key, off the
teddy server and this is why its authing with no password.

As someone suggested, use the -v option to ssh to see what files its using.
To stop this happening remove the private key files from each of the bear
servers ~/.ssh/ directories.
