Hi Jeffrey,
The offending host is 59.64.129.175. To err on the side of caution we attempted to block the entire netblock. According to whois data, that's 59.64.128.0-59.64.159.255.
iptables -A INPUT -s 59.64.128.0/19 -p TCP -j DROP
After reboot cpu usage is still high and access_log still shows useless requests from the host:
Did you actually arrange for your iptables rule to be reinstated at boot?
If you just configure a rule as above, but don't save it, it will disappear ar reboot.
