Using sudo ping -f (URL) on a Mac gives the message:
Request timeout for icmp_seq as a reply.
How can I fix this?
11 Answer
The reply means the target host is unreachable which is not an error and can happen using a plain 'ping' as well. Now, using the -f(lood) option, some firewalls or hosts can believe it's a DoS attack and drop the icmp packets silently.
Do you really need this -f option ? It can overflow the network and should be avoided as much as possible.
