[Dshield] Interesting information about SSH scans

I set up some honeypots and also made a few
modifications to the ssh daemon to print out the
passwords these scans were trying to use. I noticed a
reduction in the number of scans, but I still got a
few in the last few days.

Basically I noticed 2 different scans.

** Scan 1 - Attempt many passwords against the root
account and a lot of attempts against common/default
accounts (with the password being the same as the
account name). Interesting is that some of the
passwords for root doesn't look very simple and some
use keyboard combinations (probably common too). 
Received scans of this type from 7 different IPS (same
passwords, users, etc).

** Scan 2 - Attempt a lot of strange passwords against
the root and admin account. Look bellow to see why I
think they are strange. Looks like the scanner is
broken :)
Received scans of this type from 3 different IPS.


*** User, password combinations:
