Hi,

My father recently setup a new 7.0-Release system for some web development. I use ssh to login remotely. I've normally not had any trouble configuring authentication through public key encryption using ssh-keygen and such. I have for myself a id_rsa.pub and an id_rsa key pair that I use for this purpose.

Normally, I just copy, via scp, the file id_rsa.pub to my ~/.ssh/authorized_keys file on the remote host and the next time I attempt a login all is well. That is, I don't have to enter my password. However, on my Dad's new machine, this isn't the case. I still have to enter the password.

Now, I've looked through his /etc/ssh/sshd_config file and nothing in there looks odd, or different, from other remote hosts I do this on. So, I'm embedding a copy/paste of an ssh login session on my father's host using -v -v to ssh:

[/usr/home/andy/MCH]
-> ssh -v -v malumgat

[...]

debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Trying private key: /home/andy/.ssh/identity
debug1: Offering public key: /home/andy/.ssh/id_rsa
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,keyboard-interactive

It seems OpenSSH (on your dad's box) hasn't recognized your private key, so how about checking permissions of ~/.ssh/authorized_keys and ~/.ssh on his box. Or how about enabling verbose logging on his box, using 'LogLevel' parameter in sshd_config.
