How to configure ssh known_hosts?

Question

I am using OpenSSH on Red Hat Linux. How do I set up the known_hosts file in the .ssh folder so that I can log on to remote machines without typing in a password?

Answer 1

On your local machine, you need to create a private/public key files.

Log in, they type "ssh-keygen -t rsa", and just press enter when asked for the passphrase (no password). It will put two files in your ~/.ssh/ folder. They are "id_rsa" and "id_rsa.pub". Don't give out your "id_rsa" file, it is private. The "id_rsa.pub" is the public key and you need to add it to the remote computer's "authorized_keys" file. Once it is added, you should be able to connect with no password.
