试试
iptables -A INPUT -s 60.12.109.16 -p tcp --dport ssh -j DROP
?

these are zombies infected by backdoor programs, not from actual person.
banning that IP is not helpful because you will soon find other IPs trying
the same thing.
make sure you disable remote root access, by setting PermitRootLogin to no
in sshd_config (of course, make your account sudoer first), then
sudo /etc/init.d/sshd restart
you can also install tripwire to automatically disable intruders after
failed passwords
