nmap scripts for ping of death, syn flood, etc..

[fs5]

I need an nmap script that will test a router for ping of death, syn flood, etc... basically anything nmap can do to crash a router I'd like a script for.

No, I'm not trying to be a script kiddie and this is only for private use.

edit:
sorry I was looking for nmap related stuff when I should've been looking for something more general... I think nessus will do what I need... thanks.
