SYN cookies firewall version 0.9.1 for Linux kernel 2.2.12 - 2.2.17.
Written by Bordi Zhou(bordi@bronzesoft.org) Oct. 20, 2000.

NOTE:This patch is for kernel 2.2.17

Install:
  Please read the file "Install" within the package.

Basic idea:
  Please read file "doc.html" within the package. Or visit www.bronzesoft.org

Config:
  After installation, "man ipscfwadm".

Test:
  To test it, you should set up an environment like this:


                                ------------ 
         ------------          |SYN cookies |             ----------
        | attacker's |---------| firewall   |------------|protected |
        |    host    |         |            |            |  server  |
         ------------          |------------|             ----------

  The firewall has two network interface cards (For example, two ethernets),
One connects to the attacker's host, the other connects to the protected
server. Run a SYN flooding tool in attacker's host to flood the server.

  NOTE: Just test it on machines you have the permission.

Happy hacking!
