PHP Firewall
 

An adaptation of this is posted for tsse 5.6 elsewhere, however I am going to post what I can about it so that others will adapt this to other codes as well. Now the reason why is I have used this over a year on maybe 15 different installs, and I have seen it work, very well. I installed a tsse nightcrawler about 10 days ago and it got hit pretty good, as you can see in the pic.

The site stayed up and running to the extent that they never really knew it and even ran their shoutcast. Was it all because of this? Hardly, but the server stayed up and that's a pretty good hit, so for the price of 5 minutes to download this and add it has paid of several times on the sites I have installed it on.
