This host is built up just for 3+ days, but the system logged some unauthorized ssh login attempt. Someone was trying to login with guessed user names from IP 213.192.59.x and 222.73.18.x.

Here's a list of the user names he/she used, interesting.

I have reconfigured sshd to use public key authentication only so that further attempt will fail. I would like to address something here in case you are happened to be the evil guy - this host is just a tiny website hosting my personal weblog and homepage, the host resources are very limited since I am too poor to rent a better one ;-), it's not worth to take as a zombie system for other evil usage. So please stop.
