Raspberry Pi ssh login

[francesco scaglione]

I've downloaded an image from here:

ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/arm/armv6/ISO-IMAGES/10.0/

copied it on my SD card and booted the Raspberry Pi. Now, since the
machine is headless, I'm trying to login through ssh from another
computer, as "pi" or as "root", but without success. Is there a
default password?

Thank you very much,
Francesco
