  32 .Sh NAME
  33 .Nm mtest
  34 .Nd test multicast socket operations
  35 .Sh SYNOPSIS
  36 .Nm
  37 .Sh DESCRIPTION
  38 The
  39 .Nm
  40 utility
  41 is a small program for testing multicast socket operations.
  42 .Pp
  43 It accepts the following commands, interactively, or as part of a scripted
  44 input file (useful for automated testing):
  45 .Bl -tag -width "a ifname e.e.e.e e.e.e.e" -compact -offset indent
  46 .Pp
  47 .\"
  48 .It Ic a Ar ifname Ar mac-addr
  49 Join the link-layer group address
  50 .Ar mac-addr
  51 on interface
  52 .Ar ifname .
  53 The group address should be in IEEE 802 MAC format,
  54 delimited by colon (':') characters.
  55 .It Ic d Ar ifname Ar mac-addr
  56 Leave the link-layer group address
  57 .Ar mac-addr
  58 on interface
  59 .Ar ifname .
  60 .It Ic m Ar ifname Ar 1/0
  61 Set or reset ALLMULTI mode on interface
  62 .Ar ifname .
  63 This option is deprecated and is now a no-op.
  64 .\".It Ic p Ar ifname Ar 1/0
  65 .\"Set or reset promiscuous mode on interface
  66 .\".Ar ifname .
  67 .Pp
  68 .It Ic j Ar mcast-addr Ar ifname Op Ar source-addr
  69 Join the multicast address
  70 .Ar mcast-addr
  71 on the interface with name
  72 .Ar ifname .
  73 .Pp
  74 If an optional source
  75 .Ar source-addr
  76 is specified, a source-specific join will be performed;
  77 if
  78 .Nm
  79 is already joined to the multicast address, the source
  80 will be added to its filter list.
  81 .Pp
  82 .It Ic l Ar mcast-addr Ar ifname Op Ar source-addr
  83 Leave the multicast address
  84 .Ar mcast-addr
  85 on the interface with address
  86 .Ar ifname .
  87 If a source
  88 .Ar source-addr
  89 is specified, only that source will be left.
  90 .\"
  91 .It Ic i Ar mcast-addr Ar ifname Ar n Ar source-addr ...
  92 Set the socket with membership of
  93 .Ar mcast-addr
  94 on interface
  95 .Ar ifname
  96 to include filter mode, and add
  97 .Ar n
  98 sources beginning with
  99 .Ar source-addr
 100 to the inclusion filter list.
 101 .\"
 102 .It Ic e Ar mcast-addr Ar ifname Ar n Ar source-addr ...
 103 Set the socket with membership of
 104 .Ar mcast-addr
 105 on interface
 106 .Ar ifname
 107 to exclude filter mode, and add
 108 .Ar n
 109 sources beginning with
 110 .Ar source-addr
 111 to the exclusion filter list.
 112 .\"
 113 .It Ic t Ar mcast-addr Ar ifname Ar source-addr
 114 Set the socket with membership of
 115 .Ar mcast-addr
 116 on interface
 117 .Ar ifname
 118 to block traffic from source
 119 .Ar source-addr .
 120 .\"
 121 .It Ic b Ar mcast-addr Ar ifname Ar source-addr
 122 Set the socket with membership of
 123 .Ar mcast-addr
 124 on interface
 125 .Ar ifname
 126 to allow traffic from source
 127 .Ar source-addr .
 128 .\"
 129 .Pp
 130 .It Ic g Ar mcast-addr Ar ifname Ar n
 131 Print
 132 .Ar n
 133 source filter entries for
 134 .An mcast-addr
 135 on interface
 136 .An ifname .
 137 .\"
 138 .Pp
 139 .It Ic f Ar filename
 140 Read commands from the file
 141 .Ar filename .
 142 .It Ic s Ar n
 143 Sleep for
 144 .Ar n
 145 seconds.
 146 .It Ic ?\&
 147 List legal commands.
 148 .It Ic q
 149 Quit the program.
 150 .El
 151 .Sh IMPLEMENTATION NOTES
 152 For each command implemented by
 153 .Nm ,
 154 the address family of each argument must be identical; it is not possible
 155 to mix IPv4 multicast memberships with IPv6, for example.
 156 .Pp
 157 To support IPv6, all commands have now changed to accept an interface
 158 name rather than an interface address.
 159 For IPv4, the program will perform
 160 a lookup of the primary IP address based on the interface name.
 161 This may fail if no primary IP address is assigned.
