How do I configure SSH on OS X?

Question

I'm trying to SSH from one Mac running OS X 10.6 to another. Seems to work fine via a password, but I can't get it to use a RSA key instead. Where is the ssh configuration file on OS X and what is the command to reload SSH?

Update

What I'm asking is how to configured advanced options. For example, on Ubuntu there is a ssh config file at /etc/ssh/sshd_config and if you do something like change the port or disable password authentication for a particular user (PasswordAuthentication no) you need to run /etc/init.d/ssh reload to reload the config. I didn't see that file on OS X, so was just wondering where it was. I am aware of the ~/.ssh ~/.ssh/authorized_keys and `~/.ssh/config

Answer 1

The SSH configuration is stored in

/private/etc/sshd_config

To stop and start sshd:

launchctl stop com.openssh.sshd
launchctl start com.openssh.sshd

Answer 2

You can restart SSH somewhere in the sharing dialogs, but you don't have to. According to the man page on apple.com keys go to the ~/.ssh/authorized_keys file.
