ethspray [-v] rx|tx DEV:MAC [DEV:MAC]*
-v be verbose (also keeps process in foreground)
-r --rate packets per second [10]
-l --loss N packet loss trigger level [3]
-R --rtime N recoverytime in seconds after reconnect until recovered [200]
-F stay in foreground (no daemon)
-e --exec PRG run this program to handle events
Ethspray has two modes: 'rx' and 'tx'
rx mode is the receiver mode.
The receiver will expect packets from the MAC-addresses listed.
If sequential packet loss is detected the alarm function will trigger.
tx mode is the transmitter mode.
The transmitter will send packets to all MAC-addresses listed at the given rate.
Exec program:
The program/script given to the '-e' switch receives event information in argv.
$1 = MAC
$2 = RESET|FAIL|RECONNECT|RECOVER|LOSS
RESET is sent at program startup.
$3 = HH:MM:SS.ms
$4 = (LOSS PERCENTAGE)
