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

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 ]

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.

-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.

"-d

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.

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