MCASTREAD(1)		  BSD General Commands Manual		  MCASTREAD(1)

NAME
     mcastread -- read multicast packets forever

SYNOPSIS
     mcastread [-v46] [-s source] interface address port [file]

DESCRIPTION
     The mcastread utility reads UDP multicast data continuously, and writing
     the data to the standard output.  You must	specify	the interface, multi-
     cast address and UDP port number or service name (services(5)).  If you
     specify the file, mcastread will write the	data to	the file.

     With -v, mcastread	generates more messages.

     With -4 and -6, you can use either	IPv4 or	IPv6.  By default, mcastread
     uses IPv6.

     With -s source option, you	can also specify the sender address of the
     multicast packet.	If your	kernel supports	IGMPv3 / MLDv2,	this source
     information is passed to the upstream multicast router.

RETURN VALUES
     mcastread will exit with positive value on	errors.
