    Hello,
    Number one, I have to admit that openssh has always been a bit of a
    "black magic" to me. The everyday stuff is a breeze (ssh scp), but I've
    had hell of a time setting up passwordless ssh for a little MPI cluster
    I have running here at school.
    I got the darned thing running about a year ago, having tried various
    methods, I finally STUMBLED on a working setup... unfortunately a hasty
    rm -rf .ssh here and there really messed things up.
    I've now decided I should learn how to get openssh-3.1p1 setup for
    passwordless ssh the right way, and in such a way that I know what's
    going on and can properly maintain my cluster.
    Please note the I've been RTFMing for the past 5 hours... and am on the
    verge of my nerves (hence the babbling on in my post).

    WHAT I NEED: passwordless login for ALL users from "master" to all
    "nodes" 1-14...

    WHAT I'M TRYING TO DO: I've worked on the one "master" to see if I can
    get pswd'less ssh on there first...
    -sshd creates the keys.
    -I take /etc/ssh/ssh_host_key.pub and copy it into
    /etc/ssh/ssh_known_hosts with "master" prepended
    -create /etc/hosts.equiv AND /etc/ssh/hosts.equiv with "master" listed

    QUESTION: Why the HECK does it keep asking me for a password to
    login???? Should I use protocol I ? And if so how do I enable it ( I
    have tried, and it would still insist on a password)

    Any suggestion and/or help ARE MUCH APPRECIATED.
    THANK YOU,
    Mike
