To specify an interval of five seconds between packets sent to host opus, enter: ping -i5 opus Information similar to the following is displayed: PING opus.austin.century.com: (129.35.34.234): 56 data bytes 64 bytes from 129.35.34.234: icmp_seq=0 ttl=255 time=5 ms The attacker hopes that the victim will respond with ICMP "echo reply" packets, thus consuming both outgoing bandwidth as well as incoming bandwidth. The TCP/IP specification states that the TTL field for TCP packets should be set to 60, but many systems use smaller values (4.3 BSD uses 30, 4.2 used 15). You can set preload mode with the -l {packets} option. In this attack, the attacker sends a large number of ICMP Echo Request or ping packets to the targeted victim's IP address. The maximum possible value of this field is 255, and most Unix systems set the TTL field of ICMP ECHO_REQUEST packets to 255. Every time a ping reply has been recieved it will echo a backspace character, deleting the period. as in example? Ping is a command tool available in Cisco/Windows/Unix/Linux Operating Systems to check the network connectivity between two computers.
