    I have 2 machines:

    One runs sshd 2.4.0. I have succesfully connected to this host with
    publickey authentication from other machines. Let's call this machine1.

    I have installed a new machine, with Slackware 8.1. This has openSSH
    preinstalled. Let's call this machine2.

    On machine2 I generate a version 2 rsa key with:

    ssh-keygen -t rsa

    This results in:

    id_rsa private key
    id_rsa.pub public key

    I put the public key on machine1 (on useraccount, (same accountname I
    use on machine2)).
    Changed ~/.ssh2/authorization by adding:

    Key id_rsa.pub

    Now I log into machine1 from machine2.

    dubhead = machine1
    dubhead2 = machine2

    marc@dubhead2:~$ ssh -v -2 dubhead

    marc@dubhead's password:

    Why does it say: 'try pubkey: /home/marc/.ssh/id_rsa' while this is not
    a public key but a private key.

    As you can see publickey authorisation does not work, so I'am left with
    password authentication.
