( ProxyPass )
The software blocks open proxies and shared passwords. Its written in C just like Iprotect and features a realtime admin. I had it installed and that was the end of the bullshit with those proxy hackers.
Iprotect/Pennywize/StopThatHacker - just dont work.
Lets say you have Pennywize set to block a user after 5 bad auths. These hackers use 1000's of proxies to attack you and get 5 guesses on each one. If the hacker has 8000 proxies to use, he gets 40,000 guesses all total. Whats the point in even blocking ?
