Hi, I am relatively new to GNU/linux and using slackware and something very weird happened and I would really appreciate some help figuring out what it was. Thank very much.
My terminal suddenly printed something like "broadcast message from root" but I couldn't finish reading because my computer suddenly shutdown.
Here is the relevant parts of /var/log/messages http://pastebin.com/YhqZk7az
I changed all my passwords immediately in case someone had found it an "ssh" into my computer to shut it down, but I don't think this is actually what happened. On the other hand I do not know what did happen and I am a bit worried about it, as well as of course not wanting it to happen in future.
So any advice on how to track this down or thoughts on what it might be would be greatly appreciated. Thanks again..
