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

SYNOPSIS
nemesis-arp [-rsTRvZ?] [-d IFNAME] [-D ADDR] [-h MAC] [-H MAC] [-m MAC] [-M MAC] [-P FILE] [-S ADDR]

DESCRIPTION
nemesis 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 ADDR
    Specify the destination IP address of the injected ARP frame.

-h MAC
    Specify the sender hardware address within the ARP frame only.

-m MAC
    Specify the target hardware address within the ARP frame only.

-P 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.

-r  Enables ARP/RARP replies.

-R  Enables RARP mode.

-s  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 ADDR
    Specify the source IP address of the injected ARP frame.

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

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

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

-Z  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.
