We received a notification today, from a company that checks our network for
vulnerabilities, that the web servers we host are vulnerable to HPing
(http://www.hping.org/). The company stated that using this tool it is
possible to ping the box via port 80 and thus open to service denial
attacks(?!). Even do trace routes etc. Has anybody had any experience with
this, and more importantly, how would one go about blocking this type of
"ping"?

Thanks!

Chad
