PF for nearly ALL *nix-Systems!

Hay, I found this one in a Forum. That guy said that it has all the functionality of a real Personal Firewall like ZoneAlarm!

I think he's right!


#!/bin/bash
# Great Personal Firewall för Unix-Systems
echo -n Starting firewall.
while true; do
  sleep 1
    echo -n .
    if [ $(($RANDOM%13)) -eq 2 ]; then
    break;
 fi
    done
    echo
    echo "Your system is now secure\!"
    while true; do
    sleep $(($RANDOM%53))
    echo "Blocked attack from host
  
$(($RANDOM%256)).$(($RANDOM%256)).$(($RANDOM%256)).$(($RANDOM%255+1))
    on port $(($RANDOM%65535+1))!!!"
    done
exit 0

packets can have broadcast IPs as the source IP.
