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.
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.
