iptables -A INPUT -p icmp -j DROP(But the guy running the probes is making a good counter argument)
Maybe if you delay pings by some amount (20ms? 100ms?), or randomize the delay, you can do a lot better at masking location.
I disabled ICMP reply on my home router.
it's a bit like greeting-back ppl on the street.
not doing it will not make you invisible. it will break somebody's assumption of decency, but most ppl don't care either way.
Doesn't actually help at all because the BGP announced prefix of your IP can still be tracerouted. You won't be physically far from it.
Say if your ISP announces 125.15.18.0/17 and you're in 125.15.29.145, a traceroute will still yield a pretty good approximation of where you're at. The last hop ping is really quite immaterial here.
