Busybox doesn't do that as far as I know, as it's intended as a single-user
/sbin/init replacement. You'll need a full-featured userspace with an actual
init daemon (sysvinit, systemd, etc) and an ssh daemon (openssh, or if you want
something smaller, dropbear - works well on embedded things like routers...)
And of course things like /bin/login and all the /etc files that needs in order to work...
