    Automated SSH scans that have been happening for a while.
    If you aren't getting them then your SSH server isn't working :-P .

    There are a few ways to stop them cluttering up your logs, simplest is
    to put SSH on a port other than 22, as these are not often targeted
    scans - they are blanket scans. Another effective technique is to drop
    any IP's that appear to be brute forcing you , eg...
    http://www.debian-administration.org/articles/187

    Generally this is nothing to worry about if you have decent passwords on
    your user accounts, but the log clutter can be a nuisance.
