I echo what you and others have said.  If you aren't using it, turn it off.

You will continually see such traffic in your logs when hosting a
service on a default port.  There are always script kiddies out there
sweeping a range of IPs with their cracking tools.  You won't notice
the good ones because they will be slow and methodical.

I had SSH activated for a while on a box because I needed remote
access to administer the web server (I was hosting a pretty basic site
for some elementary school kids - kid friendly links).  I wrote a
couple of scripts to carve out offending traffic in my logs and tag a
standard paragraph to it advising the IP owner of malicious traffic
originating from their network.  Some responded (most did) thanking me
for advising them and stating that they would look into it.  Usually
another infected machine as was pointed out in this thread.  Much like
if someone was able to compromise your box and then use it to initiate
attacks against other systems.  Your ISP would come to you telling you
that they will take you off the grid until you correct the problem.
