    Hi,

    I have a linux cluster (RedHat 7.3) with 4 linux boxes. In order for ssh
    to operate without password I seted up private authentication keys using
    ssh-keygen -t rsa command. Created authorized_keys and known_hosts files
    and everything works fine. The problem is that every time I open a new
    window or start a new session I have to carry out several commands in
    order to use this ssh without password. The commands I need to do is
    following

     ssh-agent $SHELL
    ssh-add

    I also need to write my passphrase and only after this procedure I am
    able do carry out any command on any nodes directly from server without
    typing password or passphrase. (For example, command like
    ssh -n har3 date). Har3 is the name of one of the node.

    What I want is to skip this procedure with ssh-agent and ssh-add
    commands. Is it possible to modify some configuration files of ssh so
    that I would be able to carry out command on nodes when I write it
    actually on server (like
    above command ssh -n har3 date) directly when I start a new session
    without ssh-agent and ssh-add commands.

    Thank you in advance David
