I was getting a brute force attack on an FTP Server. This program helped to stop the attack and gave me confidence that the server is more secure than the vanilla install.
The configuration wasn't as simple as I had hoped. There is not a /etc/phrel.config file yet. I had to add to a script that's run at every reboot to automate the execution of the script.
The other downside is the need for root access. It probably will not work for some VPS environments, but you can always ask the admin. I'm sure once they see the thing, they'll want it installed.
Be very careful on your settings. Try testing it with a small decay (-D) first, like 10 seconds or so. Of course, have a way of getting to the box other than ssh when testing. Otherwise, you may need a reboot. Note, even if you test the FTP port, all ports are closed when you get blocked.
It's definitely worth the effort of learning how this thing works. It's so very cool. After a few failed logins, the entire IP is dropped for a period of time. It can even be throttled down to a certain number of packets/second after an offense.
The cool thing is that its protocol independent. It will work for FTP, SSH, HTTP, DNS, SMTP, and any other protocol tcp or udp. Learn one tool and protect all protocols on your network. Could also work great on a router box.
So very happy for this one. I give it a 10!
Use for animating
This is very impressive software. 3D animation is a very complicated technology and this software did a wonderful job encapsulating all the minor details.
I like how it can import .wings files and .3ds files all into one scene. This is the perfect environment for putting together a sophisticated 3D animation. I especially like the options of creating a variety video files as the final output.
I would suggest using Wings3D to create any complicated subjects to animate. Together, these products are as good as any professional product that I've used.
