CHOPARP(8) System Manager's Manual CHOPARP(8) NAME choparp -- cheap and omitted proxy ARP SYNOPSIS chpoarp if_name mac_addr [-]net_addr[/net_mask] ... DESCRIPTION choparp is a easy-to-use proxy ARP daemon. It watches ARP request packets visible on the interface specified by argument if_name, and sends proxy ARP reply to the sender if the ARP request queries the MAC address (ethernet hardware address) for the network specified by net_addr/ net_mask. mac_addr is th MAC address to be published for the specified hosts. It is normally the address of if_name. The format of mac_addr must be 6 colon- separated bytes of hexadecimal value, such as 00:00:01:01:14:46. The key- word auto can also be used to use the address of if_name from the system configuration. A carp(4) virtual router address can be specified as vhid:<hex> net_addr must be in dotted quad notation (for example 133.138.1.134) or be a 32 bit hexadecimal value starting with "0x" (for example 0x858a0186). net_mask can likewise be speficied as a dotted quad or hexadecimal value, or alternatively as a mask length. The following address specifications are therefore equivalent: 192.168.98.0/255.255.254.0 192.168.98.0/0xfffffe00 192.168.98.0/23 Multiple addresses can be specified. Addresses can be excluded by preced- ing them with - EXAMPLES If you have network interface "ne0" with MAC address "00:00:01:01:14:16", and would like to send proxy ARP reply for 192.168.0.64/26, the argument would be as follows: choparp ne0 00:00:01:01:14:46 192.168.0.64/255.255.255.192 BUGS Supports Ethernet interfaces only. Handles single interface at a time. (you can start multiple choparp for multiple interfaces, though). FreeBSD ports 15.quarterly November 20, 2014 CHOPARP(8)
