Example 30–2 Sending Packets to Hosts on the Network

The following example sends 100 packets to a host (-c 100), with a packet size of 2048 bytes (-l 2048). The packets are sent with a delay time of 20 microseconds between each burst (-d 20).

$ spray -c 100 -d 20 -l 2048 pluto
sending 100 packets of length 2048 to pluto ...
no packets dropped by pluto
