    Hi,

    I'm trying to write a script that automatically ssh-es into a network, executes a command, and logs out

    ssh <login-node>
    <command>
    exit

    I know the trouble is with "scope". Are there ssh options that will let me get around this? So that I can perform the command on the login-node via a script executed off the login node?

    Thanks

    If you want to log in via a script then you must set up ssh keys to remove the need for a password.

    The remote execution of the command is very simple :
    ssh myuser@myremotelocation "some command"

    That will log in to the remote location, execute the command and log out.
