.Sh NAME
.Nm mtest
.Nd test multicast membership socket operations and ioctls
.Sh SYNOPSIS
.Nm
.Sh DESCRIPTION
The
.Nm
utility
is a small program for testing the multicast membership socket operations
and ioctls.
It accepts the following commands, interactively:
.Bl -tag -width "a ifname e.e.e.e e.e.e.e" -compact -offset indent
.It Ic j Ar g.g.g.g Ar i.i.i.i Op Ar s.s.s.s
Join the IP group address
.Ar g.g.g.g
on the interface with address
.Ar i.i.i.i .
.Pp
If an optional source
.Ar s.s.s.s
is specified, a source-specific join will be performed;
if
.Nm
is already a member of the group, the source
will be added to its filter list.
.Pp
.Ar i.i.i.i
may be specified as 0.0.0.0 to use the default interface,
although this is legacy behaviour and is not recommended,
as group memberships are keyed to each individual link.
.It Ic l Ar g.g.g.g Ar i.i.i.i Op Ar s.s.s.s
Leave the IP group address
.Ar g.g.g.g
on the interface with address
.Ar i.i.i.i .
If a source
.Ar s.s.s.s
is specified, only that source will be left.
.It Ic a Ar ifname Ar e.e.e.e.e.e
Join the Ethernet group address
.Ar e.e.e.e.e.e
on interface
.Ar ifname .
.It Ic d Ar ifname Ar e.e.e.e.e.e
Leave the Ethernet group address
.Ar e.e.e.e.e.e
on interface
.Ar ifname .
.It Ic m Ar ifname Ar 1/0
Set or reset ALLMULTI mode on interface
.Ar ifname .
.It Ic p Ar ifname Ar 1/0
Set or reset promiscuous mode on interface
.Ar ifname .
.\"
.It Ic i Ar g.g.g.g Ar i.i.i.i Ar n Ar x.x.x.x ...
Set the socket with group membership of
.Ar g.g.g.g
on IPv4 address
.Ar i.i.i.i
to include filter mode, and add
.Ar n
sources beginning with
.Ar x.x.x.x
to the inclusion filter list.
.\"
.It Ic e Ar g.g.g.g Ar i.i.i.i Ar n Ar x.x.x.x ...
Set the socket with group membership of
.Ar g.g.g.g
on IPv4 address
.Ar i.i.i.i
to exclude filter mode, and add
.Ar n
sources beginning with
.Ar x.x.x.x
to the exclusion filter list.
.\"
.It Ic t Ar g.g.g.g Ar i.i.i.i Ar s.s.s.s
Set the socket with group membership of
.Ar g.g.g.g
on IPv4 address
.Ar i.i.i.i
to block traffic from source
.Ar s.s.s.s .
.\"
.It Ic b Ar g.g.g.g Ar i.i.i.i Ar s.s.s.s
Set the socket with group membership of
.Ar g.g.g.g
on IPv4 address
.Ar i.i.i.i
to allow traffic from source
.Ar s.s.s.s .
.\"
.It Ic g Ar g.g.g.g Ar i.i.i.i Ar n
Print
.Ar n
source filter entries for group
.An g.g.g.g
on IPv4 address
.An i.i.i.i .
.\"
.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.
.It Ic q
Quit the program.
