ICMP echo request packets. Why are pings not allowed to certain
systems?   acid_kewpie 02-08-2011 02:21 AM  Well it just depends
on your security policies. ICMP will imply that a system exists
(although can be spoofed by honeypots etc.) Personally I don't
like permitting ICMP in general. If you have no business
connecting to a web service on a given machine, what right would
you have to know if that machine can be pinged?
