ssh key authentication problem...

[Peter Harrison]

Can anyone help me debug an ssh key-based authentication problem?

I have an 8.1-R server running sshd, with one user account. On the server, I've used ssh-keygen to generate id_rsa  and id_rsa.pub.

On my laptop I then pulled the id_rsa.pub file over and:

% cat id_rsa.pub >> .ssh/authorized_keys

Now I try to login from the laptop (also 8.1-R) to the server. It pauses for a second and presents me with a 'Password:' prompt, so obviously the key authentication isn't working.

He's a debugging chunk from sshd run with '-ddd' flags:

debug1: PAM: initializing for "peter"

debug1: attempt 1 failures 0
debug2: input_userauth_request: try method publickey

Anyone suggest what I'm doing wrong?

TIA.
