Since an echo reply packet is sent back for each incoming packet, the amount of data in the outgoing network traffic is equally high. The attacker hopes that the victim will respond with ICMP "echo reply" packets, thus consuming both outgoing bandwidth as well as incoming bandwidth. On networks with low RTT this mode is essentially equivalent to flood mode. -t option is used to specify TTL field value in the IP header for, -T option is used for set special timestamp options, -V option is used to display the version and exit.
