and to make it a bit easier...
So you generated your public key on the local system using ssh-keygen...now you need to copy it to the remote system and append right?
1. cd into /root/.ssh on your source box
2. Use this command:
cat *.pub | ssh <hostname> "cat - >> /root/.ssh/authorized_keys"
You will read out the the contents of your rsa/dsa .pub keys, using ssh to copy and append to the destination host. After you type the password (for the last time), then try again something simple such as:
ssh <hostname> date
And if you've done everything correctly, no password.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)
NAME
ssh-keysign -- ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host-
based authentication is used.
/etc/ssh/ssh_host_dsa_key-cert.pub
/etc/ssh/ssh_host_ecdsa_key-cert.pub
/etc/ssh/ssh_host_rsa_key-cert.pub
If these files exist they are assumed to contain public certificate information corresponding with the private keys above.
SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)
HISTORY
ssh-keysign first appeared in OpenBSD 3.2.
