NAME¶

nemesis-ethernet — Ethernet Protocol (The Nemesis Project)

SYNOPSIS¶

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.
