NAME

       mcfirst - check if you can receive IPv4/IPv6 multicast

SYNOPSIS

       mcfirst [ -46vr ] [ -I interface ] [ -c count ] [ -t time ] [ source ] group port

DESCRIPTION

       mcfirst	can  be  used to check whether one can receive multicast packets from a host. The host may send any type of multicast packets, any
       application, IPv4 or IPv6, ASM or SSM.  mcfirst joins the specified (source) and group, and listens to the specified port.  mcfirst will by
       default exit when the first packet is received, and print how long it waited.

OPTIONS

       The options are as follows.

       -4     Force IPv4

       -6     Force IPv6

       -v     Print version

       -r     Print rate information only

       -I interface
	      Interface to join on

       -c count
	      Stop after receiving count packets. Default is 1 unless time limit is specified

       -t time
	      Exit  after time seconds. Default is to exit after the first packet. If both count and time are specified, mcfirst will exit as soon
	      as one of them is satisfied.

SEE ALSO

       ssmping(1) a tool for checking whether can receive SSM.

       dbeacon(1) a distributed beacon multicast implementation.

BUGS

       Please report them to Stig Venaas <venaas@uninett.no>, the author of this tool.

HISTORY

       mcfirst was developed by Stig Venaas during the early days of the m6bone, the IPv6 multicast backbone.
