    Try this.

    The first time you run ssh-agent redirect the output to a file.
    $ssh-agent > /tmp/agentid

    Add the following to your .bash_profile or whatever is appropriate.
    . /tmp/agentid
    (create a new session or reload your profile: ". ~/.bash_profile")

    Once ssh-add is run all subsequent sessions should be ready to go.

    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

    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
