Sets the Time-To-Live of generated ICMP packets.
+=item B<Size> I<size>
+
+Sets the size of the data payload in ICMP packet to specified I<size> (it
+will be filled with regular ASCII pattern). If not set, default 56 byte
+long string is used so that the packet size of an ICMPv4 packet is exactly
+64 bytes, similar to the behaviour of normal ping(1) command.
+
=item B<SourceAddress> I<host>
Sets the source address to use. I<host> may either be a numerical network
