Ethernet Protocol (The Nemesis Project)

## NAME

nemesis-ethernet - Ethernet Protocol (The Nemesis Project)

## SYNOPSIS

**nemesis-ethernet \[-vZ?\] \[-d** *Ethernet-device* **\] \[-H** *source-MAC-address* **\] \[-M** *destination-MAC-address* **\] \[-P** *payload-file* **\] \[-T** *Ethernet-type* **\]**

## DESCRIPTION

**The Nemesis Project** is designed to be a command line-based, portable human IP stack for UNIX-like  and Windows systems.  The suite is broken down by protocol, and should allow  for useful scripting of injected packets from simple shell scripts.

**nemesis-ethernet** provides an interface to craft and inject Ethernet frames allowing the user to  inject an entirely arbitrary Ethernet frame.

## ETHERNET OPTIONS

- \-d Ethernet-device

  Specify the name (for UNIX-like systems) or the number (for Windows systems)  of the *Ethernet-device* to use (eg. fxp0, eth0, hme0, 1).

- \-H source-MAC-address

  Specify the *source-MAC-address* (XX:XX:XX:XX:XX:XX).

- \-M destination-MAC-address

  Specify the *destintion-MAC-address* (XX:XX:XX:XX:XX:XX).

- \-P payload-file

  This will cause nemesis-ethernet to use the specified *payload-file* as the payload when injecting Ethernet frames.  The maximum payload size is  1500 bytes in order to account for the maximum Ethernet frame size.  Payloads can also be read from stdin by specifying '-P -' instead of a payload-file.

  The payload file can consist of any arbitrary data though it will be most useful to create a payload resembling the structure of a packet type not supported by nemesis.  Used in this manner, virtually any link layer frame can be injected.

- \-T Ethernet-type

  Specify the *Ethernet-type* as an integer.  Valid Ethernet types include:

  ```
  512   (PUP)
  2048  (IP)
  2054  (ARP)
  32821 (RARP)
  33024 (802.1q)
  34525 (IPv6)
  34915 (PPPOE discovery)
  34916 (PPPOE session)
  ```

- \-v verbose-mode

  Display the injected packet in human readable form.  Use twice to see a hexdump of the injected packet with printable ASCII characters on the right.  Use three  times for a hexdump without decoded ASCII.

- \-Z list-network-interfaces

  Lists the available network interfaces by number for use in link-layer  injection.

  NOTE: This feature is only relevant to Windows systems.

## DIAGNOSTICS

Nemesis-ethernet returns 0 on a successful exit, 1 if it exits on an error.
