ssh-keygen -t rsa -f ~/.ssh/id_rsa -b 2048 -Pssh-keygen -P ''; ssh-copy-id -i ~/.ssh/id_rsa user@host; ssh user@hostthat's two single quotes after the -P setting the passphrase to an empty string which I believe should be the same as no passphrase at all.ssh-keygen -P '' -f ~/.ssh/id_rsa -b 2048...will not ask you for a thing. @bwoodacre: your second command doesn't need the -i in it, that is the default (and without prompt) So, for most of you out there, if you are doing this on a new machine or machine that otherwise needs a new key to be written, your command for doing everything you need (without a passphrase) on one line is:ssh-keygen -P '' -f ~/.ssh/id_rsa -b 2048; ssh-copy-id user@host; ssh user@host...ssh user@host is obviously only for logging in when done ...and most systems don't prompt for the -b (bits) and default to 2048 :)
