|
||||||
|
.Nd Address Resolution Protocol
|
||||||
|
.Sh SYNOPSIS
|
||||||
|
.Cd "device ether"
|
||||||
|
.Sh DESCRIPTION
|
||||||
|
The Address Resolution Protocol (ARP) is used to dynamically
|
||||||
|
map between Protocol Addresses (such as IP addresses) and
|
||||||
|
Local Network Addresses (such as Ethernet addresses).
|
||||||
|
This implementation maps IP addresses to Ethernet,
|
||||||
|
ARCnet,
|
||||||
|
or Token Ring addresses.
|
||||||
|
It is used by all the Ethernet interface drivers.
|
||||||
|
.Pp
|
||||||
|
ARP caches Internet-Ethernet address mappings.
|
||||||
|
When an interface requests a mapping for an address not in the cache,
|
||||||
|
ARP queues the message which requires the mapping and broadcasts
|
||||||
|
a message on the associated network requesting the address mapping.
|
||||||
|
If a response is provided, the new mapping is cached and any pending
|
||||||
|
message is transmitted.
|
||||||
|
ARP will queue at most one packet while waiting for a response to a
|
||||||
|
mapping request;
|
||||||
|
only the most recently ``transmitted'' packet is kept.
|
||||||
|
If the target host does not respond after several requests,
|
||||||
|
the host is considered to be down allowing an error to be returned to
|
||||||
|
transmission attempts.
|
||||||
|
Further demand for this mapping causes ARP request retransmissions, that
|
||||||
|
are ratelimited to one packet per second.
|
||||||
|
The error is
|
||||||
|
.Er EHOSTDOWN
|
||||||
|
for a non-responding destination host, and
|
||||||
|
.Er EHOSTUNREACH
|
||||||
|
for a non-responding router.
|
||||||
|
.Pp
|
||||||
|
The ARP cache is stored in the system routing table as
|
||||||
|
dynamically-created host routes.
|
||||||
|
The route to a directly-attached Ethernet network is installed as a
|
||||||
|
.Dq cloning
|
||||||
|
route (one with the
|
||||||
|
.Li RTF_CLONING
|
||||||
|
flag set),
|
||||||
|
causing routes to individual hosts on that network to be created on
|
||||||
|
demand.
|
||||||
|
These routes time out periodically (normally 20 minutes after validated;
|
||||||
|
entries are not validated when not in use).
|
||||||
|
.Pp
|
||||||
|
ARP entries may be added, deleted or changed with the
|
||||||
|
.Xr arp 8
|
||||||
|
utility.
|
||||||
|
Manually-added entries may be temporary or permanent,
|
||||||
|
and may be
|
||||||
|
.Dq published ,
|
||||||
|
in which case the system will respond to ARP requests for that host
|
||||||
|
as if it were the target of the request.
|
||||||
|
.Pp
|
||||||
|
In the past,
|
||||||
|
ARP was used to negotiate the use of a trailer encapsulation.
|
||||||
|
This is no longer supported.
|
||||||
|
.Pp
|
||||||
|
ARP watches passively for hosts impersonating the local host (i.e., a host
|
||||||
|
which responds to an ARP mapping request for the local host's address).
|
||||||
|
.Pp
|
||||||
|
Proxy ARP is a feature whereby the local host will respond to requests
|
||||||
|
for addresses other than itself, with its own address.
|
||||||
|
Normally, proxy ARP in
|
||||||
|
.Fx
|
||||||
|
is set up on a host-by-host basis using the
|
||||||
|
.Xr arp 8
|
||||||
|
utility, by adding an entry for each host inside a given subnet for
|
||||||
|
which proxying of ARP requests is desired.
|
||||||
|
However, the
|
||||||
|
.Dq "proxy all"
|
||||||
|
feature causes the local host to act as a proxy for
|
||||||
|
.Em all
|
||||||
|
hosts reachable through some other network interface,
|
||||||
|
different from the one the request came in from.
|
||||||
|
It may be enabled by setting the
|
||||||
|
.Xr sysctl 8
|
||||||
|
MIB variable
|
||||||
|
.Va net.link.ether.inet.proxyall
|
||||||
|
to 1.
|
||||||
|
.Sh MIB Variables
|
||||||
|
The ARP protocol implements a number of configurable variables in
|
||||||
|
.Va net.link.ether.inet
|
||||||
|
branch
|
||||||
|
of the
|
||||||
|

|
MIB.

.Sh DIAGNOSTICS
|
||||||
|
.Bl -diag
|
||||||
|
.It "arp: %x:%x:%x:%x:%x:%x is using my IP address %d.%d.%d.%d on %s!"
|
||||||
|
ARP has discovered another host on the local network which responds to
|
||||||
|
mapping requests for its own Internet address with a different Ethernet
|
||||||
|
address, generally indicating that two hosts are attempting to use the
|
||||||
|
same Internet address.
|
||||||
|
.It "arp: link address is broadcast for IP address %d.%d.%d.%d!"
|
||||||
|
ARP requested information for a host, and received an answer indicating
|
||||||
|
that the host's ethernet address is the ethernet broadcast address.
|
||||||
|
This indicates a misconfigured or broken device.
|
||||||
|
.It "arp: %d.%d.%d.%d moved from %x:%x:%x:%x:%x:%x to %x:%x:%x:%x:%x:%x on %s"
|
||||||
|
ARP had a cached value for the ethernet address of the referenced host,
|
||||||
|
but received a reply indicating that the host is at a new address.
|
||||||
|
This can happen normally when host hardware addresses change,
|
||||||
|
or when a mobile node arrives or leaves the local subnet.
|
||||||
|
It can also indicate a problem with proxy ARP.
|
||||||
|
This message can only be issued if the sysctl
|
||||||
|
.Va net.link.ether.inet.log_arp_movements
|
||||||
|
is set to 1, which is the system's default behaviour.
|
||||||
|
.It "arpresolve: can't allocate llinfo for %d.%d.%d.%d"
|
||||||
|
The route for the referenced host points to a device upon which ARP is
|
||||||
|
required, but ARP was unable to allocate a routing table entry in which
|
||||||
|
to store the host's MAC address.
|
||||||
|
This usually points to a misconfigured routing table.
|
||||||
|
It can also occur if the kernel cannot allocate memory.
|
||||||
|
.It "arp: %d.%d.%d.%d is on if0 but got reply from %x:%x:%x:%x:%x:%x on if1"
|
||||||
|
Physical connections exist to the same logical IP network on both if0 and if1.
|
||||||
|
It can also occur if an entry already exists in the ARP cache for the IP
|
||||||
|
address above, and the cable has been disconnected from if0, then reconnected
|
||||||
|
to if1.
|
||||||
|
This message can only be issued if the sysctl
|
||||||
|
.Va net.link.ether.inet.log_arp_wrong_iface
|
||||||
|
is set to 1, which is the system's default behaviour.
|
||||||
|
.It "arp: %x:%x:%x:%x:%x:%x attempts to modify permanent entry for %d.%d.%d.%d on %s"
|
||||||
|
ARP has received an ARP reply that attempts to overwrite a permanent
|
||||||
|
entry in the local ARP table.
|
||||||
|
This error will only be logged if the sysctl
|
||||||
|
.Va net.link.ether.inet.log_arp_permanent_modify
|
||||||
|
is set to 1, which is the system's default behaviour.
|
||||||
|
.It "arp: %x:%x:%x:%x:%x:%x is multicast"
|
||||||
|
Kernel refused to install an entry with multicast hardware address.
|
||||||
|
If you really want such addresses being installed, set the sysctl
|
||||||
|
.Va net.link.ether.inet.allow_multicast
|
||||||
|
to a positive value.

.Ar interface .
|
||||||
|
Applicable only to the following operations:
|
||||||
|
display one, display all, delete all.
|
||||||
|
.It Fl n
|
||||||
|
Show network addresses as numbers (normally
|
||||||
|
.Nm
|
||||||
|
attempts to display addresses symbolically).
|
||||||
|
.It Fl s Ar hostname ether_addr
|
||||||
|
Create an
|
||||||
|
.Tn ARP
|
||||||
|
entry for the host called
|
||||||
|
.Ar hostname
|
||||||
|
with the Ethernet address
|
||||||
|
.Ar ether_addr .
|
||||||
|
The Ethernet address is given as six hex bytes separated by colons.
|
||||||
|
The entry will be permanent unless the word
|
||||||
|
.Cm temp
|
||||||
|
is given in the command.
|
||||||
|
If the word
|
||||||
|
.Cm pub
|
||||||
|
is given, the entry will be
|
||||||
|
.Dq published ;
|
||||||
|
i.e., this system will
|
||||||
|
act as an
|
||||||
|
.Tn ARP
|
||||||
|
server,
|
||||||
|
responding to requests for
|
||||||
|
.Ar hostname
|
||||||
|
even though the host address is not its own.
|
||||||
|
In this case the
|
||||||
|
.Ar ether_addr
|
||||||
|
can be given as
|
||||||
|
.Cm auto
|
||||||
|
in which case the interfaces on this host will be examined,
|
||||||
|
and if one of them is found to occupy the same subnet, its
|
||||||
|
Ethernet address will be used.
|
||||||
|
.Pp
|
||||||
|
If the
|
||||||
|
.Cm reject
|
||||||
|
keyword is specified the entry will be marked so that traffic to
|
||||||
|
the host will be discarded and the sender will be notified the
|
||||||
|
host is unreachable.
|
||||||
|
The
|
||||||
|
.Cm blackhole
|
||||||
|
keyword is similar in that traffic is discarded but the sender is
|
||||||
|
not notified.
|
||||||
|
These can be used to block external traffic to a host without
|
||||||
|
using a firewall.
|
||||||
|
.It Fl S Ar hostname ether_addr
|
||||||
|
Is just like
|
||||||
|
.Fl s
|
||||||
|
except any existing
|
||||||
|
.Tn ARP
|
||||||
|
entry for this host will be deleted first.
|
||||||
|
.It Fl f Ar filename
|
||||||
|
Cause the file
|
||||||
|
.Ar filename
|
||||||
|
to be read and multiple entries to be set in the
|
||||||
|
.Tn ARP
|
||||||

|
Entries

in the file should be of the form
