.Nm
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility
|
|
is a small program for testing multicast socket operations.
|
|
.Pp
|
|
It accepts the following commands, interactively, or as part of a scripted
|
|
input file (useful for automated testing):
|
|
.Pp
|
|
.Bl -tag -width "a ifname e.e.e.e e.e.e.e" -compact -offset indent
|
|
.\"
|
|
.It Ic a Ar ifname Ar mac-addr
|
|
Join the link-layer group address
|
|
.Ar mac-addr
|
|
on interface
|
|
.Ar ifname .
|
|
The group address should be in IEEE 802 MAC format,
|
|
delimited by colon (':') characters.
|
|
.It Ic d Ar ifname Ar mac-addr
|
|
Leave the link-layer group address
|
|
.Ar mac-addr
|
|
on interface
|
|
.Ar ifname .
|
|
.It Ic m Ar ifname Ar 1/0
|
|
Set or reset ALLMULTI mode on interface
|
|
.Ar ifname .
|
|
This option is deprecated and is now a no-op.
|
|
.It Ic p Ar ifname Ar 1/0
|
|
Set or reset promiscuous mode on interface
|
|
.Ar ifname .
|
|
.Pp
|
|
.It Ic j Ar mcast-addr Ar ifname Op Ar source-addr
|
|
Join the multicast address
|
|
.Ar mcast-addr
|
|
on the interface with name
|
|
.Ar ifname .
|
|
.Pp
|
|
If an optional source
|
|
.Ar source-addr
|
|
is specified, a source-specific join will be performed;
|
|
if
|
|
.Nm
|
|
is already joined to the multicast address, the source
|
|
will be added to its filter list.
|
|
.Pp
|
|
.It Ic l Ar mcast-addr Ar ifname Op Ar source-addr
|
|
Leave the multicast address
|
|
.Ar mcast-addr
|
|
on the interface with address
|
|
.Ar ifname .
|
|
If a source
|
|
.Ar source-addr
|
|
is specified, only that source will be left.
|
|
.\"
|
|
.It Ic i Ar mcast-addr Ar ifname Ar n Ar source-addr ...
|
|
Set the socket with membership of
|
|
.Ar mcast-addr
|
|
on interface
|
|
.Ar ifname
|
|
to include filter mode, and add
|
|
.Ar n
|
|
sources beginning with
|
|
.Ar source-addr
|
|
to the inclusion filter list.
|
|
.\"
|
|
.It Ic e Ar mcast-addr Ar ifname Ar n Ar source-addr ...
|
|
Set the socket with membership of
|
|
.Ar mcast-addr
|
|
on interface
|
|
.Ar ifname
|
|
to exclude filter mode, and add
|
|
.Ar n
|
|
sources beginning with
|
|
.Ar source-addr
|
|
to the exclusion filter list.
|
|
.\"
|
|
.It Ic t Ar mcast-addr Ar ifname Ar source-addr
|
|
Set the socket with membership of
|
|
.Ar mcast-addr
|
|
on interface
|
|
.Ar ifname
|
|
to block traffic from source
|
|
.Ar source-addr .
|
|
.\"
|
|
.It Ic b Ar mcast-addr Ar ifname Ar source-addr
|
|
Set the socket with membership of
|
|
.Ar mcast-addr
|
|
on interface
|
|
.Ar ifname
|
|
to allow traffic from source
|
|
.Ar source-addr .
|
|
.\"
|
|
.Pp
|
|
.It Ic g Ar mcast-addr Ar ifname Ar n
|
|
Print
|
|
.Ar n
|
|
source filter entries for
|
|
.Ar mcast-addr
|
|
on interface
|
|
.Ar ifname .
|
|
.\"
|
|
.Pp
|
|
.It Ic f Ar filename
|
|
Read commands from the file
|
|
.Ar filename .
|
|
.It Ic s Ar n
|
|
Sleep for
|
|
.Ar n
|
|
seconds.
|

.It Ic ?\&

List legal commands.

|
|
.Sh IMPLEMENTATION NOTES
|
|
For each command implemented by
|
|
.Nm ,
|
|
the address family of each argument must be identical; it is not possible
|
|
to mix IPv4 multicast memberships with IPv6, for example.
|
|
.Pp
|
|
To support IPv6, all commands have now changed to accept an interface
|
|
name rather than an interface address.
|
|
For IPv4, the program will perform
|
|
a lookup of the primary IP address based on the interface name.
|
|
This may fail if no primary IP address is assigned.
