# If you would like to connect to your machine through ssh without
# being asked for a password you should do this.
# 1. Create a public/private key pair
#        ssh-keygen -t rsa
#        Please Do not forget not to write any passphrase, just empty
#        for no passphrase for this to work
# 2. Copy te file id_rsa.pub to the $HOME/.ssh directory of the machine
#    you wish to connect to, where $HOME is the direcotory fo the user
#    you would like to connect as. /root/.ssh in the case you would
#    like to connect as root. Consider you would like to connect as the
#    user user
#        scp $HOME/.ssh/id_rsa.pub (line break)
#        usuario@server.remoto:/home/user/.ssh/authorized_keys2
# 3. Now you can connecto the remote server with out being asked for a password.
#        ssh -l usuario server.remoto
