fix return/exit codes in some cases. Add -S which will delete any old entry first. Add "auto" in proxy case, so it finds the right interface automatically.

.Sh DESCRIPTION
|
|
The
|
|
.Nm arp
|
|
program displays and modifies the Internet-to-Ethernet address translation
|
|
tables used by the address resolution protocol
|
|
.Pq Xr arp 4 .
|
|
With no flags, the program displays the current
|
|
.Tn ARP
|
|
entry for
|
|
.Ar hostname .
|
|
The host may be specified by name or by number,
|
|
using Internet dot notation.
|
|
.Pp
|
|
Available options:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
The program displays all of the current
|
|
.Tn ARP
|
|
entries.
|
|
.It Fl d
|
|
A super-user may delete an entry for the host called
|
|
.Ar hostname
|
|
with the
|
|
.Fl d
|
|
flag.
|
|
.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
|
|
.Ar temp
|
|
is given in the command.
|
|
If the word
|
|
.Ar pub
|
|
is given, the entry will be "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 ether_addr can be given as `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
|
|
ether_addr will be used.
|
|
.It Fl S Ar hostname ether_addr
|
|
Is just like
|
|
.Fl s
|
|
except any existing arp entry for this host will be deleted first.
|
|
.It Fl f
|
|
Causes the file
|
|
.Ar filename
|
|
to be read and multiple entries to be set in the
|
|
.Tn ARP
|
|
tables. Entries
|
|
in the file should be of the form
|
|
.Pp
|
|
.Bd -filled -offset indent -compact
|
|
.Ar hostname ether_addr
|
|
.Op Ar temp
|
|
.Op Ar pub
|
|
.Ed
|
|
.Pp
|
|
with argument meanings as given above.
