# nemesis-arp(1)

ARP/RARP Protocol (The Nemesis Project)

## NAME

nemesis-arp - ARP/RARP Protocol (The Nemesis Project)

## SYNOPSIS

**nemesis-arp \[-rsTRvZ?\] \[-d** *Ethernet-device* **\] \[-D** *destination-IP-address* **\] \[-h** *sender-hardware-address* **\] \[-H** *source-MAC-address* **\] \[-m** *target-hardware-address* **\] \[-M** *destination-MAC-address* **\] \[-P** *payload-file* **\] \[-S** *source IP address* **\]**

## 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-arp** provides an interface to craft and inject ARP frames allowing the user to  specify any portion of an ARP frame.

## ARP/RARP OPTIONS

- \-D destination-IP-address

  Specify the *destination-IP-address* of the injected ARP frame.

- \-h sender-hardware-address

  Specify the *sender-hardware-address* within the ARP frame only.

- \-m sender-hardware-address

  Specify the *target-hardware-address* within the ARP frame only.

- \-P payload-file

  This will cause nemesis-arp to use the specified *payload-file* as the payload when injecting ARP/RARP frames.  The maximum payload size is  1472 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.

- \-r reply-enable

  Enables ARP/RARP replies.

- \-R RARP-Enable

  Enables RARP mode.

- \-s Solaris-mode-enable

  When performing ARP requests, rather than zero out the 6 byte target hardware  address field within the ARP frame, Solaris systems copy the target hardware  address from the Ethernet header into this field.  This option emulates Solaris systems by setting the target hardware address within ARP frame to  ff:ff:ff:ff:ff:ff rather than the standard 00:00:00:00:00:00.

- \-S source-IP-address

  Specify the *source-IP-address* of the injected ARP frame.

- \-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.

## DATA LINK 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).

- \-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-arp returns 0 on a successful exit, 1 if it exits on an error.
