    SSH client uses password authentication by default, so if you want
    to authenticate with private key then you need to explicitly setup
    "IdentityFile" directive or use "-i" command line parameter to
    select a key file.
    It is a good practice, at least for me, to explicitly setup separate
    entries for each host, because different hosts might have different
    keys, different ports and protocols, different users, different
    encryption algorithms, etc.
    If you have one-ssh-key-for-everything and always use the default
    port, then you can use "Host *" directive to choose default
    settings, but doing this might complicate things in the future.
