SEND_ARP(8)						      System Manager's Manual						       SEND_ARP(8)

NAME

       send_arp - Send out one ARP packet with source/target IP and Ethernet hardware addresses suuplied by the user.

SYNOPSIS

       send_arp sndr_ip_addr sndr_hw_addr targ_ip_addr targ_hw_addr [src_int [src_hw_addr [dest_hw_addr]]]

DESCRIPTION

       send_arp This program sends out one ARP packet with source/target IP and Ethernet hardware addresses suuplied by the user.  It compiles and
       works on Linux and will probably work on any Unix that has SOCK_PACKET.

       The idea behind this program is a proof of a concept, nothing more.  It comes as is, no warranty.  However, you're allowed to use it  under
       one condition: you must use your brain simultaneously.  If this condition is not met, you shall forget about this program and go RTFM imme-
       diately.

       sndr_ip_addr
	      Sender IP address for ARP packet.
