LogChekker searches log files sent from your router to your e-mail client. It presents results in IP address, port number and the count from the IP address on that specific port. You can then do a quick search on any IP address to see if there are more incidents on other ports from the selected IP address. If more incidents were found, you can then (by using the copy/paste button) copy the IP address to the search box and search again. This time you will be presented with an IP address port number and the number of times the IP address was found on different port numbers.
