    There is one way we are using to logon to the devices through script for
    automization of backup. Where we have written a script which run's on Linux

    spawn ssh X.X.X.X

    expect "*login:*"
    send "admin\r"
    expect "password:"
    send "Pre$!denT\r"
    expect "*->*"
    send "(the command which you want to execute)\r"
    expect "*(the result line which you expect)*"
    send "exit\r"

    and so on.
    In front of username we have hardcoded the username and infront of password
    we supply the hardcoded passwords.

    I think (not sure) that you can use this for sftp too in place of ssh in
    above lines.
