Tracking connected IPs
tail -n 10000 yourweblog.log|cut -f 1 -d ' '|sort|uniq -c|sort -nr|more
# Take a look at the top IP addresses. If any stand out from the others, those would be the ones to firewall.
netstat -n|grep :80|cut -c 45-|cut -f 1 -d ':'|sort|uniq -c|sort -nr|more
# This will look at the currently active connections to see if there are any IPs connecting to port 80. You might need to alter the cut -c 45- as the IP address may not start at column 45. If someone was doing a UDP flood to your webserver, this would pick it up as well.
#On the off chance that neither of these show any IPs that are excessively out of the norm, you would need to assume that you have a botnet attacking you and would need to look for particular patterns in the logs to see what they are doing. A common attack against wordpress sites is:
GET /index.php? HTTP/1.0
#If you look through the access logs for your website, you might be able to do something like:
