Help with my question, please.

[COMCAST]

The question is. What password am I being asked? I dearly need to know! 
I've tried my servers password of  "fast" and my remote password of 
"raspberry". And it still gives me the same permission error..

root@debian:/etc/ssh# ssh debian@192.168.0.213
Debian GNU/Linux 12
debian@192.168.0.21's password:
