Behavior/Usage:
Usage: mturoute [-t] [-f] [-m MAX_PAYLOAD_SIZE] host
Flags:
-t : Toggles ‘traceroute‘ mode. (Default is off)
-f : Allow fragmentation. This will return the max ping size that the
target host will respond to, but not necessarily the MTU.
-w : Set the number of milliseconds to wait for a response (default 3000).
-r : Set the maximum number of probe retries on timeout (default = 3).
-i : Set the interval between two echo requests.
-d : Increases the debugging level. Reports ICMP status/failures.
-m : Sets a maximum payload size to test. (Default is 10000)
-v : Print version info and exit.
-z : Fill ICMP packets with random data.
-p : Fill ICMP packets with a specified pattern.
-s : Skip speed optimizations.
-x : Redact IP addresses in output.
-h,-? : Print usage information and exit.
