This script allows to determine MaxTranssmitUnit size for current network.
Argument "-M" selects Path MTU Discovery strategy:
- "do" means prohibit fragmentation, even local one;
- "want" do PMTU discovery, fragment locally when packet size is large;
- "dont" do not set DF flag.
Argument "-s" specifies payload size. Value 1472 produces frames of 1500 bytes. And value 1473 is for frames 1501 byte which is more than usual MTU.
Arguments "-c 3 -A" are used to send 3 packets as fast as possible (adaptive ping).
