  37 .Sh NAME
  38 .Nm arp
  39 .Nd address resolution display and control
  40 .Sh SYNOPSIS
  41 .Nm arp
  42 .Ar hostname
  43 .Nm arp
  44 .Fl a
  45 .Nm arp
  46 .Fl d Ar hostname

  53 .Sh DESCRIPTION
  54 The
  55 .Nm arp
  56 program displays and modifies the Internet-to-Ethernet address translation
  57 tables used by the address resolution protocol
  58 .Pq Xr arp 4 .
  59 With no flags, the program displays the current
  60 .Tn ARP
  61 entry for
  62 .Ar hostname .
  63 The host may be specified by name or by number,
  64 using Internet dot notation.
  65 .Pp
  66 Available options:
  67 .Bl -tag -width Ds
  68 .It Fl a
  69 The program displays all of the current
  70 .Tn ARP
  71 entries.
  72 .It Fl d
  73 A super-user may delete an entry for the host called
  74 .Ar hostname
  75 with the
  76 .Fl d
  77 flag.
  78 .It Fl s Ar hostname ether_addr
  79 Create an
  80 .Tn ARP
  81 entry for the host called
  82 .Ar hostname
  83 with the Ethernet address
  84 .Ar ether_addr .
  85 The Ethernet address is given as six hex bytes separated by colons.
  86 The entry will be permanent unless the word
  87 .Ar temp
  88 is given in the command.
  89 If the word
  90 .Ar pub
  91 is given, the entry will be "published"; i.e., this system will
  92 act as an
  93 .Tn ARP
  94 server,
  95 responding to requests for
  96 .Ar hostname
  97 even though the host address is not its own.
  98 .It Fl f
  99 Causes the file
 100 .Ar filename
 101 to be read and multiple entries to be set in the
 102 .Tn ARP
 103 tables.  Entries
 104 in the file should be of the form
 105 .Pp
 106 .Bd -filled -offset indent -compact
 107 .Ar hostname ether_addr
 108 .Op Ar temp
 109 .Op Ar pub
 110 .Ed
 111 .Pp
 112 with argument meanings as given above.
