SSH login attempts from hundreds of different IP addresses. Could not get my IT department to block the port at the firewall. It's an old Mac OSX server - thus, why the POS locked up within minutes of the attack starting. Come to think of it, I haven't used SSH for ages. I always ARD into it to administer. CLICK. No more SSH.
At least it made me review my server security. I was way too lax, knowing how little value the data, or even the server itself, has. But the attack itself still annoyed me, so I tightened that bitch up real good (well, as good as you can tighten up an old Mac server).
