fawx.c is an igmp-8+frag attack for linux, similar to ssping.c, that sends oversized fragmented IGMP packets to a box either making it freeze (WinNT/9x), or lagging it to hell and back. Since most Win32 firewalls dont support IGMP, the attack successfully penetrates most systems, making it much more effective than an ICMP attack which is likely to be filtered. It has successfully crashed NT4.0+sp1+2, Win95, Win95 with ConSeal PC firewall blocking icmp, Win95 with McAfee PC firewall. It also passed undetected through ipfwadm and ipchains (useful for flooding).
