Just ignore it, if your passwords are long enough and are NOT based on 
words that can be found in dictionaries. Change the passwords from time 
to time AND keep your sshd up to date.

If I have too many root login requests (>200) and I'am able to find out 
the attackers provider (with nslookup <ip-address>), I sometimes write 
an abuse report to the provider.

Most of these are attacks are script kiddies who are only successfull in 
case that your password is emty or matches the username
