If your circumstances allow it, I suggest moving your sshd to a port other than 22. That stopped it for me.

I have quite a few entries in /var/log/messages for connection attempts. Is there anything other than ignoring them I can do? Example is below.
Aug 21 15:48:19 machine sshd(pam_unix)[17903]: check pass; user unknown Aug 21 15:48:19 machine sshd(pam_unix)[17903]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=wsip-24-234-149-156.lv.lv.cox.net

In addition, there are options in the /etc/ssh/sshd_config file to limit allowed users. Such as AllowUsers username. Also, setting PermitRootLogin no Will increase safety.
