  Hello

  If you want to test your server, there are a number of things that you might need to do, simple attack complicated. It depends on what you want to achieve, attack type, for example, server operating system application.

  But that simple could use ICMP/ping attack or attack SYN TCP (you can easily get tools on the Net).

  Perspective PIX of firewall, you will probably need to active built-in IDS feature, limit the embryonic level and open ICMP to the target server. Make sure your ACL allows ICMP and authorized service port requests to pass through. In addition, make sure that you enable syslog and probably set for information or debugging, to capture the log.

  PIX will easily pickup the ICMP attack based on the ID services, while for the attack of TCP - SYN (targeted to your application via ACL), you can see the attempts of the newspaper.
