NAME
nemesis-ethernet - Ethernet Protocol (The Nemesis Project)

SYNOPSIS
nemesis-ethernet [-vZ?] [-d IFNAME] [-H MAC] [-M MAC] [-P FILE] [-T TYPE]

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

ETHERNET OPTIONS

-d IFNAME
    Specify the name, for UNIX-like systems, or 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).

-P 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.

    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 TYPE
    Specify the Ethernet type/length field, 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  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  Lists 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.
