I'm using the OpenSSH client on Red Hat Linux. Does anyone know how to
set up the known_hosts file in the .ssh folder to log in to and scp
into remote machines without being prompted for a password?

much appreciated,

Timo Jeranko

You have to copy your private key onto the remote machine, and add it
to .ssh/authorized_keys. For example:

on local machine do:
ssh-keygen -t rsa
scp ~/.ssh/id_rsa.pub user@remote:~/.ssh/my_key
login to the remote machine, and:
cd ~/.ssh
cat my_key >> authorized_keys
rm my_key

You're done.

PS. Some paths may vary depending on local and remote machine' OS.

Or maybe simpler:

ssh-keygen -t rsa
ssh user@remote 'cat >> .ssh/authorized_keys' < ~/.ssh/id_rsa.pub

And though that wasn't what the question asked for (note "known_hosts"),
it was probably the right answer.

/.ssh/known_hosts file is a local user database. This is used for
server authentication.
The client checks this file for the remote machine's entry to
authenticate the server.
Use Public key authenitcation for transfering files using scp. For
this, we should copy the
public key file to /.ssh/authorized_keys on remote machine rather than
private key.
