    A good article on basic SSH setup including pub/priv keys that should answer you question.

    Subject: Passwordless ssh, "once and for all"...

    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
