Looks like someone trying to break in. You *are* running fail2ban, are you
not? If not, you need to install and fire it up, now.
I see a *lot* of this... but then, I work for a US gov't federal
contractor (civilian sector), and let me assure you, I get tired of all
the attempts from China, Brazil, and other places trying to ssh in - it
really clutters my logfiles.
