## DESCRIPTION

``

``

## COMMAND

`odev ```

- Name of Ethernet device to test. See warning below.

`pkt_size ```

- Size of packet to generate. The size includes all the headers: UDP, IP, MAC, but does not account for overhead internal to medium, i.e. FCS and various paddings.

`frags ```

- Each packet will contain ``

`count ```

- Send stream of ``

`ipg ```

- Introduce artificial delay between packets of ``

`dst ```

- Select IP destination where the stream is sent to. Beware, never set this address at random. ``

`dst ```

- Select MAC destination where the stream is sent to. Default value is 00:00:00:00:00:00 in hope that this will not be received by any node on LAN.

`stop`

- Abort packet injection.

## WARNING

When output device is set to some random device different of hardware Ethernet device, ``

Do not use it on VLAN, ethertap, VTUN and other devices, which emulate Ethernet not being real Ethernet in fact.

## SECURITY

This can be used only by superuser.

This tool creates floods of packets which is unlikely to be handled even by high-end machines. For example, it saturates gigabit link with 60 byte packets when used with Intel's e1000. In face of such stream switches, routers and end hosts may deadlock, crash, explode. Use only in test lab environment.
