From linuxproblem.org:
You want to use Linux and OpenSSH to automize your tasks. Therefore you need an automatic login from host A / user a to Host B / user You don't want to enter any passwords, because you want to call ssh from a within a shell script. First log in on A as user a and generate a pair of authentication keys.
