Just as a thought, if such a DoS was so difficult, why would I be
logging lots of ICMP Type 3 packets at my firewall from IP's that have
not been connected to? The most recent one (involving approx 200
packets over a few seconds) was supposedly from 10.240.x.x, not even
available on my internal network. Quite obviously these packets are
spoofed, but if their is no real way to D0S a system with them, why
would someone spoof them?
Unfortunately, using Windows 9x, I am unable to give you tcp dumps of
the packets....if anyone knows of a program to do this, please let me
know.
