    Hello,

    Sorry if this question may seem obvious, but I've currently found no
    appropriate solution to my problem. I also hope this newsgroup is the
    right place to ask such a question.

    The problem is that I'm still asked for a password (no passphrase
    chosen) when I login with ssh to the computer where I've put my public
    key, in files called authorized_keys/authorized_keys2.

    The key pair was on generated a local FreeBSD system, and the public key
    is put on a remote Linux system.

    On the local machine, ssh -V returns :

    OpenSSH_3.6.1p1+CAN-2004-0175, SSH protocols 1.5/2.0, OpenSSL 0x0090702f

    and on the remote one, it gives :

    OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090702f

    The problem is not solved by moving from rsa to dsa.

    The debug messages are appended below.

    NB: however, everything works good when ssh connecting from the same
    local FreeBSD computer to an IRIX64 system with :
            OpenSSH_3.9p1, OpenSSL 0.9.7d 17 Mar 2004
    installed.

    Any hint greatly appreciated,
    Thanks
    Ch. D.
